Full Stack Mobile Engineer | React + Node

Full Stack Engineer | Mobile | High-Growth Tech Start-Up | London

I’m working with a product led tech start-up that’s looking for a Full Stack Engineer to join their team in London. A chance to be part of a small, high-impact team building the foundation for something big – and genuinely different.

What you’ll be doing

• Building new features in React using Expo (must-have)
• Designing and developing GraphQL APIs and backend services in Node.js
• Scaling and maintaining a modern platform built on Kubernetes, serverless, and AWS
• Integrating external services and SDKs (authentication, payments, etc.)
• Improving observability, reliability, and CI/CD pipelines
• Contributing to solution design, product discussions, and shaping the technical roadmap

What you’ll bring:

• 5+ years of experience as a full stack engineer
• Expert-level skills in React (with Expo) and Node.js
• Solid experience with GraphQL on both frontend and backend
• Experience working with modern cloud environments, preferably AWS
• Strong testing discipline and familiarity with automation and CI/CD
• A practical understanding of event-driven architecture and microservices
• Comfort working in fast-paced, ambiguous environments with frequent change

You’ll thrive here if you:

• Have built customer-facing digital products at pace and scale
• Want to play a key role in an ambitious, hands-on, and collaborative team
• Care about quality, simplicity, and getting things done
• Enjoy finding solutions, not dwelling on blockers
• Can shift gears easily — from strategy to code, from solo focus to team debate
• Value feedback and constant learning over perfection

Why join?

• No red tape. Move fast, take ownership and make decisions.
• Real impact. Your code, your ideas – all will make an impact.
• Creative freedom. Shape the product, the culture and the future.
• User-first mindset. Everything we build starts with the customer in mind.
• Start-up energy. They’re lean, focused, and full of momentum — with space to experiment and room to grow.

Hybrid role, 3 days in the London office.
