Greater London, United Kingdom Duku AI Full time

QA slows the world down. Flaky tests kill trust, stall releases, and bleed engineering velocity. Duku AI is ending that era. We’re building autonomous agents that think like engineers: they run every critical user journey, catch failures before users do, and self-heal as the codebase evolves. Real AI teammates, not test scripts that break on impact. We’re venture-backed and led by operators who’ve scaled Meta’s testing infrastructure, launched Uber’s global playbooks, and grew Deliveroo from zero to hypergrowth. We know what elite execution looks like and we’re hunting for one more builder to help us rewrite the rules of software quality. What You’ll Do Ship fast, learn faster: We deploy daily, not monthlyTalk to users, shape the roadmap: Sit in the trenches with founders on calls that define what we buildTrain AI agents: Design LLM-powered testers that explore, learn, and adapt in real timeOwn the stack: Python, TypeScript, cloud infra, from commit to productionTurn prototypes into production: Run real experiments on models, embeddings, and retrieval pipelines What We’re Looking For Relentless drive: You execute fast, adapt fasterStartup scar tissue: You’ve shipped product with no safety netFluency with AI/LLMs: LangChain, vector stores, prompt engineeringProduct obsession: You care more about outcomes than outputs Ideal Background There’s no perfect pedigree. We hire for mindset, not credentials. That said, you might have: Shipped AI features in prodBuilt something from 0 to 1Thrived in chaos with high ownership Why This Matters Software is accelerating. QA hasn’t kept up. Autonomous testing is inevitable, and we’re building it. Five years from now, every high-velocity team will rely on AI agents like ours to ship faster, safer, and smarter. Join now, and help make that future real, before someone else does. #J-18808-Ljbffr
