AI Engineer

Frontier AI startup building state-of-the-art agentic systems that automate complex, multi-step tasks typically done by humans. Well-funded, with a value prop combining cutting-edge research (in computer use and proprietary models) with forward-deployed implementation alongside enterprise clients.

You'd be joining the Agent team - a small, high-calibre group building the systems and tooling that actually makes agents work in production. This is engineering embedded in research - the model team trains the models; the agent team builds everything around them.

What you'll do

• Build and improve agent logic: planning, tool use, skills, memory, orchestration
• Work on internal and academic benchmarks to measure and push agent performance
• Translate research ideas into working systems (tool calling, new agent capabilities, training signals)
• Build and evolve the in-house agent stack used across the organisation
• Partner closely with researchers to turn ideas into production-ready agent behaviour
• Iterate quickly, experiment often, and own problems end-to-end

• Senior-level engineering experience from a high-bar environment (top AI lab, scale-up, or Big Tech)
• Strong software engineering fundamentals and system design skills
• Interest in agentic AI - prior agent experience is helpful but not mandatory
• Proactive, autonomous, and creative - you spot gaps and fill them
• Comfortable working in fast-moving, loosely specified problem spaces

This is an opportunity to build agentic AI at the frontier - not writing papers, but shipping systems that push the boundaries of what agents can do.
