Delighted to announce bloom's newest Product search, helping a long-standing retained partner in stealth make their first product hire We went to meet them when there were only 3 people in their London office that day, and just 6 in the whole company. Within 48 hours we'd agreed to partner, and help deliver their hugely ambitious hiring plans for late 2025 & throughout 2026 8 months later, they've scaled to over 50 permanent staff, with Bloom hiring over 25 Members of Technical Staff across Senior, Staff and Principal Engineers. This business is building the infrastructure for that shift: interactive, resettable training grounds, from simple websites to complex applications, where AI agents learn, explore and master real tasks through trial and error. A small, focused, ambitious team of builders with hubs in London and Paris, working hand in hand with leading AI labs to push the frontier of what's possible. You'll own the tooling that enables a 60-strong technical team to build these training environments faster, at higher quality and with less friction. A senior IC role owning the internal platform end to end: developer-facing products, quality and observability workflows that scale without adding headcount, building for a user base that's increasingly agentic as much as human. You'll prototype rather than just spec, hold strong opinions on UX for technical users, and go deep before you go wide. Not a strategy or management hire.
