Job description

Build the AI that keeps other AI in check.

As companies hand real work to AI agents, someone has to make sure those agents stay safe, compliant and auditable. That’s the whole game here: long-running agents that do risk, compliance and security work across a company’s own systems, its suppliers, and the AI agents it now runs

About the company: who will you join?

• London-based B2B AI company in the risk, compliance & security (GRC) space
• Already in production with real, paying enterprise customers
• Backed by top-tier VCs, ~£1M ARR inside the first year, founded by an ex-Palantir operator and a research-prodigy CTO
• Tiny, exceptional engineering team scaling up

About the role: what will you do here?

• Own features end to end across a TypeScript / Node + React stack
• Build and harden the systems around the agents: orchestration, guardrails, monitoring, reliability
• Integrate LLMs into real compliance and risk workflows (Anthropic-first)
• Work directly with enterprise customers to turn messy, high-stakes compliance problems into a shippable product
• Make the architectural calls that hold as the platform scales from pilots to serious production

About you: what experience do you bring?

• You live to build: ex-founders, open-source contributors, serious side-project people
• Strong production experience across frontend and backend
• Hands-on experience putting LLMs into real products, not just demos
• High energy, good technical taste, and comfortable making calls in ambiguity
• You care about doing things right; this is high-security work for high-risk customers, so reliability is the job

In-office in King’s Cross, London (4 days in, 1 from home)
