Job Description

About REalyse

REalyse operates in the PropTech space with a focus on data and analytics. We've built the foundational technologies powering some of the most advanced property data tools in the UK, enabling our customers to make better, faster, data-driven real estate decisions.

Our products bring together massive datasets on property, planning, demographics, and investment performance into a unified platform. We're a small, ambitious, and technically strong team solving complex problems in a fast-moving industry — and we're looking for someone who wants to help shape the next generation of property intelligence products.

*The Role*

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.

Requirements

*What You'll Do*

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.

What You'll Bring

We're not looking for a "jack of all trades" — we're looking for someone who

excels in full-stack development across most of our stack

and is eager to close any remaining gaps fast. 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

*Highly 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

Who You Are

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

Benefits

[TBC] per annum, depending on experience

25 days annual leave + generous parental leave

Regular social events, meetups, and game nights

International and diverse team culture

Educational resources and professional development opportunities

Hybrid working flexibility
