With an established, AI-enabled finance function and a lean leadership team, the business is now repositioning for its next phase of growth, and this role sits at the centre of that. The Role Covering a 12-month maternity leave, the Fractional Finance Director will join the leadership team alongside the CEO and CTO, reporting to the CEO, two to three days a week. This is a strategic role rather than a hands-on one: a Senior Finance Manager leads day-to-day finance, management accounts and monthly reporting with support from external accountants, so your focus is senior challenge and judgement, testing commercial assumptions, sharpening the board narrative and keeping the leadership team focused on what drives commercial impact. You will line-manage the Senior Finance Manager and the Operations Lead, and hand back cleanly at the end of the cover period. Key Responsibilities Stress-test strategic direction with the CEO and CTO, using customer, retention and unit economics data to shape priorities, resource allocation, investment decisions, forecasts and plans. Lead finance reporting to the board, including narrative, meetings and updates, and support the Chair on shareholder relations. Guide leadership team decision-making, keeping the business focused on the priorities with the biggest commercial impact. Line-manage the Senior FP&A Manager and the Operations Lead, setting priorities and supporting their development. Oversee forecasting and statutory matters, stepping in for detailed review and judgement rather than production. Own cash and treasury management. Develop the finance stack and processes, exploring how AI can deliver sharper commercial insight. Maintain continuity through the cover period and hand back cleanly. Essential Experience Qualified accountant (ACA / ACCA / CIMA). FD or CFO experience in D2C e-commerce, subscription or consumer tech. Track record of board and shareholder relationship management, and the confidence to challenge the leadership team and the board. Experience partnering a CEO and leadership team to bring clarity through change. Strong commercial and data fluency (customer cohorts, retention, CAC and LTV, pricing), and comfortable working with a modern, AI-enabled reporting stack. Proven fractional or part-time track record, with high impact in two to three days a week. Desirable Experience Subscription or credit-based pricing models. Experience repositioning a business for growth. US market experience. Rate: £600-£700/day Contract Length: 12 months (2-3 days a week) Location: London (Shoreditch), hybrid, with Thursdays in the office Start Date: December 2026 At Harmonic, we are dedicated to fostering an inclusive and equitable workplace. We actively welcome applications from individuals of all backgrounds and assure you that every candidate will be thoughtfully considered for the roles we represent, without regard to race, religion, gender expression, disability, or sexual orientation.

Interim Financial Controller Family/Founders Office London Harmonic are delighted to be partnering with a serial entrepreneur in their search for a Interim Financial Controller to sit across their business and wider interests. Alongside a portfolio of investments and property, the founder is building a number of new business ventures, the largest of which is a fast-growing tech business. These interests have grown over time and are closely tied together, and the founder now wants to put proper structure around them. The Role This is a full-time interim role, which is open to part-time fractional candidates. The brief is to bring the whole picture together: oversight of the operating businesses, the related entities, the property portfolio and the investments, and how capital moves between them. The role also involves being 'hands-on' in the new business venture, managing month-end, payroll, accounts and general bookkeeping. The founder is also thinking about a permanent founder's or family office role, and this person will help inform what that looks like. Key Responsibilities Build a single view of the founder's businesses, entities, property and investments Ownership of the finance function within the main operating business Get on top of the group and entity structure, and simplify it where it makes sense Advise the founder on funding new ventures and allocating capital across the portfolio Manage the finance and admin around the property portfolio Help design the longer-term finance structure, including the full-time hire into the operating business Stay hands-on with the detail, including the admin that comes with a multi-asset structure What We Need to See (Essential) Senior finance experience in a family office, founder's office, or PE or VC fund finance Experience across multiple entities and asset types, including complex ownership structures Exposure to investing into businesses, and getting in and out of them Hands-on and comfortable as a player-coach with no large team underneath What We'd Like to See (Bonus) Operating finance experience in a start-up or scale-up Experience working directly with a founder or principal Day Rate: £550-700 Location: London, mix of office and remote to be agreed Contract: Full-time, 6 months (open to part-time fractional candidates) Start Date: ASAP At Harmonic, we are dedicated to fostering an inclusive and equitable workplace.

Contracts Manager Digital Media London The Role The Contracts Manager will work independently across the business affairs department initially, partnering with teams across the business, owning the day-to-day contracts function and partnering with the commercial and creative teams. You'll handle a wide range of agreements, from smaller individual contracts to significant commercial deals. The role is hands-on, and there's a lot of room to grow with the business. Progression depends on the quality of your work, your drive and your ownership, not on years of experience. The plan is to expand the department within 6 months of your start, so once you settle in, you'll have the opportunity to hire and mentor a junior team member to support you. New commercial ideas come up all the time, so you'll need to give clear, practical advice that keeps deals moving. The ideal candidate is a confident communicator who enjoys being part of a busy, social office. This is perfect a role for someone who likes building relationships, working in a collaborative, high performing business, and has a clear passion for social media. Responsibilities Draft, review and negotiate talent, creator, brand partnership, sponsorship and agency agreements, including high-value commercial contracts. Negotiate key terms including fees, payment terms, exclusivity, termination, liability and indemnities. Manage IP, content ownership, image rights and usage rights provisions, including paid media, whitelisting and extended usage. Act as the internal point of contact for compliance matters, escalating significant matters to leadership. Identify contractual and commercial risk while finding practical ways to move deals forward. Coordinate disputes and potential claims, instructing external counsel where needed. Maintain and improve contract templates, processes and internal guidance as the business scales. Ad hoc tasks to support the wider leadership team What We Need to See (Essential) Around 3+ years of commercial contract drafting and negotiation experience. A background in entertainment, media, publishing, TV, advertising, social media or talent management (or generally creative, IP led businesses) Experience in an entrepreneurial, non-corporate environment, handling a high volume of contracts with competing priorities. Package: Salary: £45,000-£50,000 Benefits include: Frequent salary reviews and inflation raises, bonus, plus private healthcare, monthly performance incentives, team trips and an early finish on Fridays Working pattern: 5 days per week in-office with flexibility to reduce to 4 days following probation, based in North London If this role is of interest, please apply online or get in touch with Halle at Please feel free to share this with any friends or colleagues who may be interested.

Fractional Financial Controller VC-Backed Hardware Tech Scale-Up London / Hybrid The Client Harmonic is delighted to be partnering with a well-funded, VC-backed hardware technology business that combines its own software with physical manufacturing. The business has grown quickly into an international, multi-site operation and is now at the point where its accounting foundations need to catch up with the scale of its operations. The Role Reporting into the Finance Director, the Fractional Financial Controller will come in part-time between now and the end of January to own a focused set of manufacturing accounting work ahead of a permanent Financial Controller hire. The scope is narrow, specialist and high impact: designing a chart of accounts that fits a growing manufacturing business, and setting up the accounting policies and processes for work in progress, inventory, fixed assets and leases. This is a hands-on technical accounting role, not a general finance lead role; fundraising, payroll and wider finance operations are out of scope. You will leave behind a structure and set of policies the permanent Financial Controller can run from day one. Key Responsibilities Design and implement a chart of accounts built for a multi-site, multi-entity manufacturing business, supporting reporting by site, product line and customer. Set up WIP accounting, including how labour, machine time and overheads are captured and absorbed into jobs, and how WIP is valued and released at month end. Establish inventory accounting covering raw materials, work in progress and finished goods, including costing method, valuation and provisioning. Build the fixed asset register and depreciation policy for machinery, tooling and site fit-outs, including useful lives, capitalisation thresholds and componentisation where relevant. Implement lease accounting for property and financed equipment, including calculating right-of-use assets and lease liabilities, and the ongoing journals. Write clear accounting policies and month-end procedures so the work can be handed over to the incoming permanent Financial Controller. Work with the Finance Director, operations and the external auditors to make sure the treatment is robust and audit-ready. Essential Experience Qualified accountant (ACA / ACCA / CIMA). Hands-on experience of WIP and inventory accounting in a manufacturing, engineering or industrial business, including job or standard costing and overhead absorption. Strong fixed asset and depreciation experience in a capital-intensive environment. Practical lease accounting experience under IFRS 16 and/or the amended FRS 102 lease requirements. Has designed or redesigned a chart of accounts for a growing business. Able to start immediately and deliver a defined scope within a short timeframe on a part-time basis. Desirable Experience Multi-site or multi-entity manufacturing, including overseas entities. Hardware, engineering or contract manufacturing background. Experience linking accounting to operational or ERP data (job costing, MRP or shop-floor systems). Previous interim or project work setting up manufacturing accounting ahead of a permanent hire. Day Rate: £400-£500 per day Commitment: 1-2 days per week Location: London, hybrid Duration: 3 Months (potential to extend) Start Date: Immediate Please feel free to get in touch with Ewan Fenley for more information ().

Interim Financial Controller VC-Backed Hardware Manufacturing Scale-Up London / Hybrid The Client Harmonic is partnering with a well-funded, VC-backed hardware technology business that combines its own software with a fast-growing physical manufacturing operation, making high-value components for demanding engineering customers. Two years after founding, and having raised significant capital, it has grown into an international group with entities across the UK, US and Europe. The business has scaled faster than its accounting. A Finance Director has recently joined to professionalise the function, a permanent Financial Controller is being recruited for early 2027, and in the meantime the accounts need putting right now. The Role Reporting to the Finance Director, the Interim Financial Controller will start immediately on a full-time basis to stabilise and rebuild the group's accounts ahead of the permanent hire. Day-to-day bookkeeping is outsourced, so the job is to review and correct what the external accountants have produced, redesign the chart of accounts, put balances in the right places and set the guardrails so the group reports correctly and is ready for its first Big Four audit next year. This is a narrow, technical and hands-on remit. There is no structure to inherit and no team to delegate to: you will know the standards and do the work yourself, across manufacturing, inventory, capex, debt financing, franchise arrangements and four entities. It is messy and it is demanding, but the impact is high: the work will give the business a clear view of where its costs come from and how it is performing. Key Responsibilities Redesign and implement the chart of accounts in Xero for a multi-entity manufacturing group, so costs and performance can be reported properly by entity, site and activity. Review the outsourced accountants' work, correct misposted and incorrectly processed transactions, and clean up historical balances. Set up WIP and inventory accounting across raw materials, work in progress and finished goods, including valuation, production costing and overhead allocation. Build the fixed asset register and depreciation policies for machinery, tooling and site fit-outs, and account correctly for capital expenditure. Implement lease accounting for property and financed equipment, and account correctly for the group's debt financing. Bring the monthly management accounts to a reliable, accurate standard across all four entities, including intercompany balances. Set the accounting policies and guardrails the external accountants work to, and coach them on best practice. Lay the foundations for a Big Four audit and hand over a clean set of accounts and policies to the permanent Financial Controller. Essential Experience Qualified accountant (ACA preferred, ACCA or equivalent), ideally Big Four audit trained. Post-qualification experience in manufacturing, aerospace, defence, engineering, automotive or another capex-heavy business carrying significant inventory and fixed assets. Strong technical command of IFRS and UK accounting standards, including inventory, fixed asset and lease accounting. Hands-on experience of WIP, inventory valuation, CAPEX, and production costing. A doer: comfortable getting into the detail yourself, without a team, in a business with little existing structure. Available immediately or at very short notice. Desirable Experience Redesigning a chart of accounts or cleaning up accounts ahead of an audit. Multi-entity reporting and international consolidation, including US and European entities. Working knowledge of Xero. What This Role Is Not Not a transactional role; bookkeeping sits with the external accountants, and you fix their output and hold them to the standard. Not a systems, automation or process-design role; technical accounting depth is what matters here. Not a team leadership role; there is no team to direct, and the work is yours to do. Day Rate: £450-600 per day (dependent on experience) Location: London, hybrid. In the office for the first week to get up to speed, then 1 to 2 days a week in the office with the rest remote Duration: 3 months initially, potential to extend. Start Date: Immediate Please feel free to get in touch with Ewan Fenley for more information (). Please feel free to share this with any friends or colleagues that may be interested.

We actively welcome applications from individuals of all backgrounds and assure you that every candidate will be thoughtfully considered for the roles we represent, without regard to race, religion, gender expression, disability, or sexual orientation.

Interim Financial Controller AI & Hardware Deep Tech Business Hybrid The Client Harmonic is partnering with a venture-backed deep tech business that pairs proprietary AI software with its own sensing hardware, already in use with UK government customers. Having recently closed a significant funding round and grown from under ten people to more than thirty in a year, the business is moving from R&D into production, with its first batch of units in build and large contracts in sight. Finance needs to be ready before those orders land. The Role This is a hands-on interim of around six months, working alongside the Chief of Staff and closely with the COO. You will take a finance function that has grown faster than its processes, get the ledger right, deliver the December year-end and leave clean foundations and processes. It is primarily a fixer's role rather than a management one, with real scope to shape how finance works. You will also coach a part-qualified accounts assistant. Key Responsibilities Review and correct nominal coding across the ledger, clearing out catch-all codes. Put inventory, cost of sales and fixed asset accounting on a proper footing, including stock, paid and unpaid customer trials, and demonstration units. Lead the December year-end and audit preparation, with the accounts turned round within four months. Build a rolling cash flow forecast, linking committed purchase orders to cash. Produce clear quarterly management accounts for the founder and board, written in plain English. Tighten purchase-to-pay controls in a newly implemented PO system: PO detail, supplier terms, payment status and moving suppliers onto account. Support R&D tax credit claims, lease accounting for new premises, and the set-up of invoicing and support-package billing ahead of larger contracts. Work alongside the external accountants, challenging their output where needed. Essential Experience Qualified accountant (ACA / CIMA / ACCA). Financial control experience in a hardware, manufacturing or physical product business, with strong grounding in inventory, cost of sales and fixed assets. Strong, current technical accounting, including delivering a year-end and audit. A genuinely hands-on approach: comfortable working from incomplete records and fixing problems at source. Able to explain finance clearly to non-finance founders and to develop junior team members. Desirable Experience Experience in a scaling, venture-backed or engineering-led business; sector movers are welcome. R&D tax credit claims. Sage 50 and purchasing or inventory systems. Day rate: £450-600 per day (Outside IR35) Contract: 6 months Location: Hybrid; 1-2 days per week in Cambridge. Start Date: ASAP For more information, get in touch with Ewan Fenley ().
