- You will define the technology stack for the frontend team, looking to grow to 5 engineers by end of 2025.
What They’re Looking For:
- Deep frontend engineering experience using modern JavaScript/TypeScript frameworks (React, Angular, or similar).
- Comfort designing frontend architectures in greenfield environments.
- A CS or technical background - you understand what’s happening under the hood.
- Bonus: experience with 3D/mapping libraries (Mapbox, Cesium, WebGL) or backend work in Rust, Python, or C++.
Why Join Them?
- Mission with Impact – You’ll be building tools that have real-world significance in national security and defence.
- True Ownership – You’ll have end-to-end control over a mission-critical product, with direct access to users and real influence over product direction.
- Elite Team – Work alongside top engineers and researchers in a focused, no-ego culture that values initiative, creativity, and velocity.
- Startup Momentum – Competitive salary (up to £110k), meaningful equity, and the chance to grow with a fast-scaling company at the intersection of AI and defence.
