About Our Team
Our Full stack engineering team brings together experienced engineers, diverse perspectives, and a flat team structure that enables visibility and impact from day one. With 40–50 professionals across the practice, we deliver some of the most exciting projects in the market — from next‑generation fintech payment platforms to global insurance systems deployed across multiple countries.
AI is an important part of our work, but this role is grounded in strong software engineering fundamentals. We are looking for senior engineers who enjoy architecture, system design, and end‑to‑end delivery, with a genuine interest in modern technologies, including AI.
The role requires Security Clearance or ability to get SC in short timescales.
About the Role
We are seeking a Senior Full Stack Engineer who is passionate about building high‑quality software and designing robust systems. You will work on complex, large‑scale solutions across multiple technology stacks, collaborating closely with clients and internal stakeholders.

This is a true full stack role, offering exposure to a broad range of technologies and architectures. You will continuously upskill while working alongside highly talented engineers, selecting the most appropriate tools and languages for each challenge.
Contribute to diverse and meaningful projects
