Join an early-stage AI-defence startup as a founding-level frontend engineer to design and build the core frontend platform that operators and engineers will use to control and understand autonomous systems. You will develop responsive, intuitive UIs that distil complex data into real-time situational awareness, working closely with users and cross-functional teams in AI, robotics, and systems engineering. The role includes defining the frontend technology stack and growing the frontend team to around five engineers by the end of 2025. This position offers meaningful ownership, competitive pay (up to £110k), and equity at a mission-driven company.

Full Job Description
Shape the Interface to the Future of Autonomous Defence
Join one of the UK’s most ambitious AI-defence startups, backed by top-tier investors and moving fast. They are building intelligent systems that operate in high-stakes environments and looking for an founding level engineer to craft the interface through which humans will guide, trust, and collaborate with these machines.
What will I do?
You’ll own the design and development of the core frontend platform – the window into their technology. This means building responsive, intuitive UIs that distil complex data into insight, enable precision control of autonomous systems, and deliver situational awareness in real time. You’ll work directly with users (from engineers to field operators) and collaborate daily with top minds in AI, robotics, and systems engineering. 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.
