Full Stack Engineer

Full-Stack Engineer – London

A high-growth, AI-native enterprise software startup is looking for seasoned Full-Stack Engineers in London to help build and scale their AI-enabled workspace for professional services, investment banking, and asset managers.

What you’ll be doing

• Building and maintaining frontend web applications using React and Next.js
• Developing, testing, and deploying backend services and APIs (Python preferred, e.g. Django, FastAPI)
• Working closely with founders, design, growth, and other engineers to ship high-impact features
• Ensuring scalability, performance, security, reliability and maintainability across the full stack
• Contributing to cloud infrastructure setup and optimisation (AWS, GCP or Azure), containerisation, deployment pipelines, monitoring and optimisation
• Implementing CI/CD pipelines, automated testing, monitoring, and related DevOps practices
• Mentoring junior engineers and helping improve engineering practices across the team

What they’re looking for

• At least 5 years’ professional software engineering experience
• Strong experience delivering production-grade web applications with React and Next.js
• Solid backend skills, preferably in Python, with good understanding of both relational and NoSQL databases
• Familiarity with Git and collaborative workflows, background workers/task queues (e.g. Celery, RQ), and caching/pub-sub systems such as Redis
• Experience with containerisation (Docker, Kubernetes), asynchronous processing, DevOps, and cloud deployment environments
• An ability to solve complex problems, work under shifting priorities, and thrive in a fast-paced startup environment

Why this is a compelling opportunity

• You’ll work side-by-side with experienced founders who’ve previously built and exited VC-backed startups
• Competitive salary plus equity, offering genuine upside
• A chance to help shape a generational product and scale it from a small team to large global deployments
• A challenging but rewarding environment: you’ll often be in unfamiliar territory, but you’ll have real ownership and visible impact

If you’re a pragmatic engineer who enjoys building robust, scalable, full-stack web systems, and you’re excited by working on next-gen enterprise AI products, this could be the right next step.
