We are seeking a Lead Engineer to head the next generation XiP Compute Service (XCS2) team. The team works across both Java and Python, and significant experience in at least one of these languages is required. In this role you will design, build, and maintain the future engine room of Citi's enterprise-scale XiNG Platform (XiP). You will be working on a Greenfield build of a major new component. The current generation of the product is responsible for 1.5 billion risk calculations at Citi every day. The next generation of the product is expected to double the customer base and bring in huge new workloads. You will work closely with other software engineers, DevOps, and our customers to define technical strategy and ensure the reliable, secure, and scalable operation of the platform. Responsibilities Take a lead in defining the long-term strategic direction of XiP: Apply your experience and skills to develop next generation of the XiP Compute Service - making it faster, utilising resources more efficiently, and scaling to even greater sizes. This means adding new features without impacting platform performance in an undesirable manner; small changes multiplied by millions of calculations carry a high cost. It also means solving hard engineering problems, such as transferring small amounts of data to a huge number of machines with minimal overhead. Collaborate with Stakeholders to Define Platform Capabilities: Partner closely with key business stakeholders, product owners, and end-users to deeply understand their requirements, define the platform's capabilities, and translate business needs into technical specifications and solutions. Drive the implementation of these capabilities, ensuring they align with strategic objectives and deliver maximum business value. An essential skill will be assessing user requirements against the overall strategy of the application - to ensure to maintain a balance between user needs and application philosophy. This will mean explaining to senior clients that some of their requests will not be accepted, and crucially why. Take on the day-to-day leadership of the development team responsible for the next generation of XiP: Lead the team's Agile/Scrum ceremonies, including sprint planning, daily stand-ups, and retrospectives, to ensure a smooth and effective development workflow. Manage the project backlog, prioritize tasks, and coordinate development efforts to align with the product roadmap and strategic goals. Provide hands on technical leadership, guiding the team in architectural decisions, enforcing coding standards, and performing code reviews to maintain high-quality, robust, and scalable code. Serve as advisor or coach to team members, allocating and overseeing work: Mentor and guide developers, providing technical advice, code reviews, and career development support. Allocate tasks based on skill sets and project priorities, ensuring balanced workloads and timely delivery. Foster a collaborative and growth-oriented team environment, encouraging best practices and continuous learning. Implement the new generation of Citi's Risk Calculation Engine: Participate in the design, development, and implementation of the next version of the XiP Risk Calculation Engine, focusing on understanding and fulfilling the needs of new platform customers. The current generation of the platform regularly parallelizes 250,000 hours of compute into a single 90-minute execution. The new platform needs to maintain this performance while enabling new workloads. Qualifications Professional software development experience with Java or Python. Solid experience with common frameworks and tooling (e.g. Spring, Spring Boot, Quarkus in Java. Or Flask, FastAPI, Pydantic in Python). Exposure to cloud platforms (e.g., AWS, Azure, GCP) and containerization (e.g., Docker, Kubernetes). Experience designing, building, and maintaining large-scale, distributed systems. Experience with RESTful API design and implementation. Exposure to NoSQL databases (e.g., MongoDB, Cassandra) is a plus. Experience with unit testing, integration testing, and test automation frameworks. Experience working in Agile/Scrum development environments. Experience with CI/CD pipelines and DevOps practices is a plus. Education Bachelor's or Master's degree in Computer Science, Engineering, or a related field.

We're looking for someone who is passionate about the backend and brings lessons learned from scaling SaaS platforms that were used by thousands of active users. About the Backend Team The backend team builds and operates the systems behind the company's cloud platform, focusing on the services and infrastructure that provide the core APIs, real time collaboration, file storage, and background processing for the editor. We also own a few full stack services that power the marketplace and customer facing experiences. How we work With a high degree of autonomy and ownership, engineers are trusted to identify problems, shape solutions, and drive the technical direction of the platform. Everyone contributes to architectural decisions and has a broad impact across our stack. While our focus is on backend systems, there are also opportunities to influence and contribute to other parts of the company, including the editor and the runtimes. Collaboration is core to our culture - teams across the company work closely to design, build, and evolve our product together. We provide modern tooling, including a generous AI/tooling budget, and encourage thoughtful use of AI assisted development where it improves speed, understanding, and quality. The team is distributed between the U.K. and U.S., where we maintain a hybrid office for collaboration and deep technical work. What you'll work on: Core APIs and services that drive the company editor, multiplayer collaboration, asset management, and the company Marketplace. Database architecture and optimization, designing schemas and queries that perform at scale and evolve with our product. Customer facing applications for authentication, accounts, billing, and team management. Observability and telemetry, building insight into how our systems behave and how customers use the company. File and asset storage systems, including object storage, CDN distribution and caching layers for fast, reliable access. Real time infrastructure for live collaboration, syncing thousands of changes per second across sessions with low latency. Distributed background systems for rendering, asset conversion, and large scale task orchestration. Scalability and reliability engineering, ensuring the company stays fast and stable as we grow. Security, compliance, and permissions models that protect our customers and meet enterprise grade standards. Tech Stack includes: Node.js (TypeScript & JavaScript), Dart/Flutter, C++, MySQL (Aurora), Redis, OpenSearch, AWS (Fargate, Lambda, CloudWatch), Docker, Terraform, GitHub Actions Requirements 8+ years of professional software engineering experience, specifically in backend and infrastructure. Proven track record of owning and delivering backend services for scaling SaaS based products that are widely relied upon by active users. Node.js experience, or strong experience in multiple programming languages and evidence of learning new ones quickly. Experience with cloud infrastructure (AWS preferred), infrastructure as code, and container orchestration. Strong SQL skills, including hands on experience with query analysis and optimization. Ability to work independently in ambiguous situations: seek out requirements, make sound decisions, and prioritize effectively. Excellent communication skills, with willingness to work directly with customers when needed. Benefits £120k-£135k or $170-195k USD base salary + stock options Unlimited holiday (PTO) and comprehensive health benefits Parental leave Regular team meetups and travel opportunities Hybrid flexible work environment with Offices in London (Farringdon) and San Francisco (Potrero Hill) Coffee and lunch on us when you're in the office Compensation may depend on the level of experience and geographic location. Visa sponsorship is not available. The successful candidate will be required to provide evidence of their right to work in the U.K. or U.S. prior to commencing employment. At the company, we are a global group of passionate designers and developers who believe in transparency, failing fast, quick iteration, and experimentation. We aim to build a diverse and inclusive culture where everyone feels supported. We have an incredible opportunity to change the world of interactive content creation. Help us accelerate the design industry's transition to the company! A real human will read your resume, cover letter, and answers to the application questions so please take a minute and tell us more about you! Applications suspected to be entirely AI generated may not be considered. We value genuine, thoughtful responses and authentic, human communication.

Full time
the company is where designers, animators, and developers build interactive experiences. Design, animate, and code in one place. What you build in the editor is what ships in your app, game, or website. No mockups, no prototypes, no handoff. The real thing. With the company, designers and developers work with the same tools. No silos. What you see in the editor is what ships in production. Companies like Spotify, Duolingo, LinkedIn, Google, and Fortune 500 automakers use our open-source runtimes to build once and ship everywhere - websites, apps, games, and vehicles.

Senior Full Stack Developer Reporting to: Engineering Manager Office Environment: Hybrid (minimum two days per week) Type: Full time, permanent Join Our Mission Skip the queue. Shape the future. See real impact. At QuantSpark, we're transforming how data and AI serve society. We combine the analytical discipline of strategy consulting with the pace and ownership of a scale-up. That means you'll work directly on the problems that matter most-whether combating economic crime, modernising government services, or accelerating commercial growth for FTSE 100 companies. Here, you'll compress 5-10 years of traditional career progression into 2-3 years. From day one, you'll lead end-to-end projects, access leadership directly (including the CEO), and build cross-industry expertise that usually takes a decade to gain. We don't just develop - we build, own, and scale solutions that shape the organisations we work with and have meaningful societal impact. Our Client Portfolio We partner with forward-thinking organisations across sectors: Private Equity & Financial Services: Portfolio analytics, AI-powered value creation, and risk management tools for global investment and wealth firms. Retail & Consumer: Pricing optimisation, inventory efficiency, and personalised engagement for major UK retailers and brands. Asset Management: Advanced investment platforms and automated risk management for asset managers. Public Sector: Trusted by multiple UK government departments for fraud analytics, predictive maintenance, and supply chain optimisation. SaaS & Manufacturing: Sector-spanning technology transformation for SaaS innovators and manufacturers. The Role You'll design, build, and scale web applications across backend and frontend, owning projects from ideation through to production - architecture, CI/CD, cloud infrastructure, monitoring, the lot. We're a small team that punches well above its weight. Client feedback is outstanding, and every engineer here has a visible impact. Day to day, you'll: Architect and deliver scalable, secure software for commercial clients across multiple sectors. Assess technical trade-offs and guide design decisions across projects. Write, review, and own high-quality code - primarily Python (Flask, FastAPI, or Django) and JavaScript/TypeScript (React preferred). Build and maintain RESTful APIs and modern frontends. Work directly with clients - communicating clearly, understanding the why behind what you're building. Feed into new client proposals and help improve internal engineering processes. Mentor junior developers through code reviews, pairing, and knowledge-sharing. Use AI coding agents to accelerate delivery whilst maintaining correctness and security. AI Engineering (Required) Hands-on experience with AI coding agents in day-to-day work - prompting, iterating, reviewing generated code, validating outputs. Working understanding of LLM fundamentals and limitations (hallucinations, context windows, evaluation). Familiarity with prompting patterns, tool use, and concepts like RAG and embeddings. Awareness of safety and privacy concerns when using AI tools (secrets, PII, licensing). Ability to integrate AI into your workflow without compromising code quality. What We're Looking For 5+ years' experience as a full-stack engineer. Strong track record delivering enterprise-grade web applications and APIs. Confident across Python backend frameworks and modern frontend (React/TypeScript). Comfortable owning the full product lifecycle. Proactive, accountable, and effective in small, fast-moving teams. Clear communicator across technical and non-technical audiences. Keen to broaden into a generalist whilst deepening your core strengths - not just staying in one lane. What We Offer Tech ownership and autonomy from day one. High-impact work - you'll see real results within months, not years. Room to innovate, not just maintain. A small, collaborative team that owns problems end to end and learns fast. Clients ambitious enough to rethink how they use data and technology. A clear path to leading technical programmes and shaping strategy - growth here is earned, not queued. Perks & Benefits £6,000 annual training & conference budget to stay at the cutting edge Up to 6% matched pension for long-term financial security Comprehensive private healthcare via Vitality EMI share options scheme - own a piece of the growth you help create Work from anywhere in the world for up to 1 month/year 25 days holiday + buy/sell up to 5 additional days Cycle-to-work scheme for sustainable commuting Central London office stocked with refreshments, socials, and vibrant atmosphere Exclusive discounts on retail, travel, tech & fitness memberships Access to cutting-edge tools, platforms, and regular tech talks & innovation time Equal Opportunities We're building a team that benefits from different perspectives, experiences, and ways of thinking. We know that great talent comes from all backgrounds, and we encourage applications from everyone who meets the role requirements, regardless of age, disability, gender identity, race, religion, sexuality, or any other characteristic. If you're unsure whether you're a perfect fit but believe you can do the job well, we'd still like to hear from you. We hire based on your skills, potential, and ability to contribute to our team, and we're committed to a fair and objective selection process for all candidates.
