CoLoop, the YC S21 startup aiming to make companies as customer-obsessed as Amazon, is hiring ex-technical founders in London. The role offers £90,000 to £180,000 GBP salary plus 0.10% to 0.40% equity for engineers who've built and shipped AI products. CoLoop's flat structure empowers engineers to own the full product cycle – gathering context, building, launching, measuring, and iterating – without product managers.

They seek candidates with proven experience in agentic AI systems and a strong opinion on AI-augmented engineering tools like Claude Code and Codex. The interview process spans two weeks, including technical evaluations and a paid contract day. CoLoop explicitly values the resilience and customer-centric mindset forged by startup failure, stating, 'If you failed to find PMF, we're building the product that helps companies avoid that fate.'
