About Lendable Lendable is on a mission to build the world's best technology to help people get credit and save money.We're building one of the world's leading fintech companies and are off to a strong start: One of the UK's newest unicorns with a team of just over 700 people Among the fastest-growing tech companies in the UK Profitable since 2017 Backed by top investors including Balderton Capital and Goldman Sachs Loved by customers with the best reviews in the market (4.9 across 10,000s of reviews on Trustpilot) So far, we've rebuilt the Big Three consumer finance products from scratch: loans, credit cards and car finance. We get money into our customers' hands in minutes instead of days. We're growing fast, and there's a lot more to do: we're going after the two biggest Western markets (UK and US) where trillions worth of financial products are held by big banks with dated systems and painful processes. Join us if you want to Take ownership across a broad remit. You are trusted to make decisions that drive a material impact on the direction and success of Lendable from day 1 Work in small teams of exceptional people, who are relentlessly resourceful to solve problems and find smarter solutions than the status quo Build the best technology in-house, using new data sources, machine learning and AI to make machines do the heavy lifting About the role We're building a larger, dedicated Platform team at Lendable, increasing our investment in the infrastructure that enables our products and engineering teams to scale. We're hiring a Technical Product Manager to sit within Engineering and connect platform technology, reliability and commercial value. You'll own what we prioritise and why, giving engineers the business context they need while helping Product and leadership understand the impact and opportunities that Platform enables. This is a hands on technical IC role, where you'll stay close to engineering through writing code, reviewing PRs and contributing to architecture discussions. Working closely with the Platform Engineering Manager and Tech Lead, you'll help shape the Platform roadmap, connect technical investment to measurable business outcomes, and build the foundations that allow Lendable to move faster and scale with confidence. What you'll be doing Own platform stability Own platform stability as a primary accountability - SLA/SLO metrics, incident rates, release quality. Hold release gating authority: block features from production that don't meet testing standards or introduce unacceptable regression risk. Enforce CI/CD standards centrally so pods don't fragment into one-off solutions. Track and report stability metrics alongside commercial outcomes - stability is the foundation that makes the rest possible. Be commercially accountable Own the business case for platform investment and answer "why are we spending six engineers on this for three months?" in terms leadership understands. Track platform impact in business terms: developer velocity, incident cost, time-to-market, reliability, capacity - e.g. "CXO rollout removes a 3-second API fan out, reducing session abandonment" or "we can now handle 20k simultaneous logins". Input into headcount and investment decisions for the platform team. Own the platform roadmap Own the platform backlog, prioritised by business value and sequenced to unblock the highest-value product teams first - not driven by technical debt or engineer preference alone. Make trade offs explicit: "if we do X now, we defer Y by Z weeks - here's what that means for products depending on us". Ensure every initiative has a defined success metric that non-engineers can track. Be the stakeholder interface Act as the single point of contact for Pod Leads: business requirements coming from pods and engineering/developer requirements flowing to pods; prioritise both in service of platform stability. Make platform work visible to leadership - regular forums with product MDs and PMs to capture upcoming dependencies before they become blockers; represent platform work in leadership reviews; translate technical milestones into business milestones. Drive cross team collaboration and buy in with other PMs; engage architecture in technical design. Escalate when product teams make requests that would create unsustainable platform load or technical debt. Contribute as an engineer Write code, review PR's, and participate in architecture design as a core part of the role - not a side project. Bring a strong technical voice to roadmap decisions without owning final architecture calls (that's Architecture and Tech Leads). What we're looking for Essential Deep, hands on engineering background - this role must be staffed by someone who has shipped production systems, not someone who has only managed backlogs. Strong commercial instinct: can build a business case, speak to P&L impact, and hold a line on ROI. Exceptional stakeholder management across product, engineering, and finance without direct line authority over all of them. Comfortable with ambiguity - platform value is often indirect and long horizon. Track record of contributing as an IC while operating at a senior, cross team level. Proactive, low ego, and clear communicator - able to hold a line with leadership and pod leads alike. Nice to have Experience in platform, infrastructure, or developer tooling contexts. Familiarity with SLA/SLO frameworks and incident management at scale. Experience enforcing CI/CD standards across multiple teams or pods. Prior work making "invisible" infrastructure legible to non technical leadership. Our tech stack Platform & backend: Kotlin, AWS, Postgres, RabbitMQ, Docker, Kubernetes. Gateway & clients: Node GraphQL gateway, React Native / TypeScript mobile app, Relay. Tooling & observability: GitHub, GitHub Actions, Jira, Confluence, Datadog, Sentry, Grafana. Interview process Quick call with the Talent Team (30 minutes) Hiring manager interview (30 minutes) Technical and Product interview (90 minutes) Culture add interview (60 minutes) Life at Lendable Winning team: the opportunity to scale up one of the world's most successful fintech companies Flexible working: flexible approach tailored to each role. Hybrid roles require three days in office weekly; fully remote roles include regular opportunities for in person connection through socials and off sites Socials & connection: opportunities and events to come together, socialise, and get to know each other beyond the office walls Health coverage: support for your physical and mental wellbeing, including private health cover Retirement & savings: long term financial wellbeing through retirement savings plans Employee referral programme: earn a competitive bonus when you refer successful new team members Office meals & snacks: enjoy a fully stocked kitchen, plus complimentary lunches prepared by in house chefs on in office days at select locations Sustainable commuting: cycle to work and electric vehicle salary sacrifice schemes available in select locations Please note: The availability and details of specific benefits vary by location and role.

The opportunityThe researchers, data scientists, and ML engineers driving AI-driven biological discovery do not yet know Substrate exists. The Community Manager is the person who will change that. This is Substrate's first dedicated community hire. You will build from scratch: the relationships, the channels, the content, the events, and the feedback loops that turn a network of interested researchers into an active, technically engaged community. You will be the external face of Substrate to the AI x biology research world, and the voice of that world inside Substrate. About SubstrateSubstrate is building and operating a network of fully autonomous wet laboratories. We are the critical infrastructure layer for AI-driven biological discovery: cloud-based data production facilities, tightly integrated with AI foundation models, that make high-quality experimental biology as accessible as compute. We are a small team, four co-founders and a founding hire class now building out, with venture funding and government grants, opening our first node in London and a second node in San Francisco in parallel. The work is hard and the timeline is compressed. We have two scientific verticals live (protein characterisation and functional genomics), a software platform that connects API calls to automated assay execution, and a commercial pipeline that spans foundation model labs, AI biotechs, pharmaceutical companies, and publicly funded research organisations. We are growing to roughly thirty people by early 2027. The roleYou will own Substrate's community function end to end. The immediate priority is establishing Substrate's presence in the communities where our most important potential users and customers already spend time: AI-biology conferences, academic research groups, frontier AI lab developer communities, and the broader open-science data ecosystem. The obvious operational pieces are real and important: building and managing Substrate's community channels, creating content (technical posts, case studies, event recaps) that demonstrates what the platform can do, representing Substrate at conferences and research events, and tracking engagement in ways that help the commercial, product and science teams make decisions. Two parts of the role are less standard, and they are why this hire matters so much to Substrate's success. The first is technical credibility. Substrate's community spans researchers who publish in leading journals and engineers who build training pipelines for frontier models. Community management here is not event coordination and social media scheduling; it is substantive engagement with people who will interrogate the science, the data quality, and the integration architecture. The Community Manager needs to be able to meet them there. The second is commercial adjacency. Community at Substrate is not a brand exercise. The relationships built through community will directly feed the commercial pipeline, inform pricing and product decisions, and define which customer segments Substrate chooses to serve deeply. You will work closely with Anna, co-founder, who leads partnerships and go-to-market, and you will operate as a genuine commercial, product and science partner. What you will do in your first twelve monthsFIRST 90 DAYS JUL TO SEP 2026 FIRST 90 DAYS JUL TO SEP 2026 Map the existing relationships the founding team holds across research institutions, frontier AI labs, pharma and Ai-native biotechs, and the AI-biotech community; understand which are most relevant to a community-first strategy. Establish Substrate's presence on the channels where the AI x biology research community spends time: a newsletter, relevant online communities, forums, podcasts, and a cadence for conference participation. Publish Substrate's first substantive technical community content: a post or article that demonstrates what the platform does and why it matters to researchers doing AI-driven biology. Identify the ten to fifteen research groups, labs, or organisations that should be Substrate's first community anchor relationships, and begin active outreach and relationship building. MONTHS 4 TO 8 OCT 2026 TO FEB 2027 Build and manage an active community presence around the London node opening: coordinate the launch event, manage researcher outreach, and produce the content that captures what Substrate's first operational period looks like. Establish a structured feedback loop between the community and the product and science teams, so that what researchers ask for and struggle with reaches the people who can act on it. Build the San Francisco community presence in parallel: identify the key organisations, events, and channels in the Bay Area AI-biology ecosystem and establish Substrate's footprint there. Develop a content calendar and production cadence that does not depend on the founding team's time to sustain. Refine the community infrastructure: channel selection, moderation policy, engagement metrics, and reporting to the commercial and product teams. MONTHS 9 TO 12 MAR TO JUN 2027 Build the community to a size and engagement level where it is a measurable input to commercial pipeline: researcher referrals, inbound interest driven by community content, and a clear record of which community relationships have become or are likely to become commercial relationships. Produce a community playbook that documents the channels, content types, event formats, and relationship cadences that work for Substrate's audience. Continue building the community infrastructure needed for the San Francisco node: what an active and engaged community looks like in the Bay Area. Who you are The pattern we are looking for combines genuine scientific credibility with commercial experience at a technical company. You will have spent five or more years close to research communities, in a developer relations, scientific outreach, partnerships, or community role at an AI, tech or biotech company. You understand how researchers and data scientists think, what they find credible, and how to earn their attention and trust. You are a strong communicator. You can write a technical post that a principal scientist will find rigorous and a graduate student will find accessible. You can run a panel discussion at a conference, write a newsletter, and manage an online community, and you bring a consistent point of view to all three. You are not looking for a role where the output is impressions and follower counts; you are looking for a role where the output is trust, relationships and BD. You are comfortable building infrastructure that does not yet exist. The community playbook has not been written. The channels have not been established. The question of what Substrate's community is for and who belongs to it is still open. MUST HAVE Five or more years in a community, developer relations, scientific outreach, or technical partnerships role at a company serving research, life sciences, or AI scientists. A demonstrated ability to build a technical community from a low base: growing engagement, producing credible content, and managing relationships with researchers, scientists, or engineers. Strong written communication skills, with a track record of producing technical or scientific content for a specialist audience. Scientific or technical literacy sufficient to engage substantively with biology, data science, and AI practitioners. Willingness to be based in London or San Francisco, with travel to the other location and to key scientific conferences NICE TO HAVE Scientific background (BSc or higher) in biology, biochemistry, computer science, or a related field. Experience in a developer relations or community role at a platform or infrastructure company. Existing relationships within the AI x biology research community AI biotechs, frontier AI labs, academic research groups, or pharma R&D. Familiarity with the conference and events landscape for AI-driven biological discovery. Experience with data or API product communities. Why this is unusual Most community management roles sit inside companies whose community is already defined: a user base that exists, a product that is live, a channel that has followers. The job is to grow and manage something that has already started. This is not that. Substrate's community is not yet built. The audience spans researchers, data scientists, ML engineers, and computational biologists working at the intersection of AI and wet-lab biology; it includes people in academic research groups, philanthropic foundations, frontier AI labs, pharma R&D, and biotech startups, all with different professional contexts and different needs from a community of this type. Part of the job is working out who the community is for and why it exists, before building it. The commercial adjacency is also unusual. In most companies, community and commercial are kept at arm's length: community builds trust, commercial closes deals, and the two teams share data and tooling but operate separately. At Substrate, the community function is one of the primary go-to-market channels, and the Community Manager is a genuine commercial partner. Compensation and equityCompensation is competitive against London and San Francisco market rates for a senior community hire at a venture-backed company, calibrated to the seniority and scope of this role. Equity is meaningful, on the standard four-year vesting schedule with a one-year cliff. . click apply for full job details
