observability, and run a reliable model release process. Work with Science to ship measurable improvements to quality, latency, safety, and reliability What you will do • Build and maintain an LLM evaluation framework (reference tests, heuristics, model-graded checks). • Define and track metrics: task success, helpfulness, hallucination proxies, safety flags, latency/cost. • Run A/B tests for prompts … models, and system prompts, analyze results, recommend rollout or rollback. • Set up observability for LLM calls: structured logging, tracing, dashboards, alerts. • Operate the model release: canary and shadow traffic, sign-offs, SLO-based rollback criteria, regression detection. • Improve core behaviors: memory write/retrieve policies and evals, intent classification, follow-ups, routing, tool-call reliability. • Create templates and docs so … other teams can author evals and ship safely. • Partner with Science, diagnose regressions and lead post-mortems. About you • Strong TypeScript or Python skills • Production LLM experience: prompts, tool/function calling, and system prompts. • Hands-on with evals and A/B testing, you can design metrics and make rollout decisions from data. • Observability: logging, tracing, dashboards, alerting • Product More ❯

one of the first Backend Engineers focused on platform and infrastructure, you'll: Build core systems capable of handling tens of millions of lines of code and large-scale LLM workloads. Own big pieces of the architecture - from job orchestration to APIs, infra, and developer tooling. Make product teams fly by building reliable, well-designed infrastructure that scales without slowing … anyone down. Tame complex LLM infrastructure (real-time usage, flaky providers, token routing - the lot). Raise the quality bar across the board: observability, auth, reliability, and more. This isn't a role for passengers. It's for engineers who love ambiguity, thrive under pressure, and see infrastructure as a multiplier. What We're Looking For 3+ years backend engineering … and the shift from scrappy MVPs to rock-solid systems. Strong system design skills - taking problems end-to-end, not just handing off parts. Bonus if you've wrangled LLM infrastructure at scale. Pragmatic, resourceful, and happy to operate autonomously in lean teams. Excited to work onsite in Soho, London with a team that's building something exceptional. Tech Snapshot More ❯
