Role
Who you are
- You’ll need to show strong, hands-on experience with:
- TypeScript & React (including modern tooling and patterns)
- TailwindCSS or an equivalent styling framework
- XState or other state machines for predictable UI logic
- REST & GraphQL API design and integration
- Data visualisation (e.g. D3.js, Recharts, or similar)
- Golang (our core backend language)
- PostgreSQL & ClickHouse, including schema design and query optimisation
- Automated testing, including unit and end-to-end (we use Vitest & Playwright)
- AWS, particularly ECS, Fargate, S3, CloudFront, Lambda, and related DevOps tooling
- You think and act like an owner — entrepreneurial, proactive, and self-driven
- You can move fast without compromising quality
- You’re comfortable with ambiguity and thrive in an environment where priorities evolve
- You care about measurable impact — technical, product, and business
- You value clarity, simplicity, and maintainability in your work
Desirable
- Familiarity with geospatial data and web mapping (e.g. vis.gl, Deck.gl, Mapbox, PostGIS)
- Proven experience building and optimising APIs for large data volumes
- Ability to design, set up, and maintain CI/CD pipelines
- Experience with React Native and delivering mobile app experiences
- Experience working with AI-assisted tooling (e.g. GitHub Copilot, Cursor, or prompt-based workflows) and awareness of their trade-offs
- Demonstrated ability to work in a start-up or scale-up environment, wearing multiple hats when required
- Strong sense of product ownership — you can articulate not only how something should be built, but why
What the job involves
- We’re looking for a senior full-stack engineer who combines strong technical depth with an entrepreneurial mindset — someone who can prototype quickly, deliver end-to-end, and help us scale and evolve our platforms
- You’ll work across our modern data and application stack — from TypeScript and React on the front end, to Golang and PostgreSQL/ClickHouse on the backend, all deployed through AWS
- You’ll have a high degree of autonomy, working within a small cross-functional team that moves fast and values clarity, quality, and measurable business impact
- Design, build, and maintain performant front- and back-end systems across our data and analytics products
- Prototype rapidly and iterate on ideas that can become new products or core features
- Deliver production-quality code and infrastructure that scales reliably
- Collaborate with product, data, and design to turn concepts into shipped features
- Contribute to architectural decisions and technical strategy
- Mentor and support other engineers in modern full-stack development practices
- Help evolve our CI/CD and deployment pipelines, with a focus on automation, observability, and developer experience

Our take
Real estate is the world's largest asset class, but decisions are too often made with incomplete and messy data, making markets unnecessarily volatile and inefficient. REalyse was founded to provide real estate big data analytics, enabling residential property developers to determine where and what to develop.
REalyse supplies cutting-edge data science and analytics to compile all property data together in an easily accessible manner. This allows investors, developers, and lenders to make decisions on complete information. It also enables users to reduce the time spent on site selection and typical appraisals by up to 90%. As a result, future properties can be built in the right places when the public actually wants and needs them.
Its platform is comprehensive, with every UK residential dataset in one place, accurate (having been collected by machines, checked by human experts, and constantly updated), and incorporates easy to use and intuitive data visualisations. This makes REalyse the best tool for helping clients create quantifiable and definitive risk/opportunity assessments - be that in existing portfolios, or planned and ongoing projects.
REalyse's approach has gained the company clients including British Land, BNP Paribas, and Legal & General. Backed by investors including XTX Markets, PiLabs, and most lately BOOST&Co, the company plans to embark on further growth, expand its sales division, and brings its comprehensive property data beyond just the UK.
