Lead Machine Learning Research Engineer

What we look for

• Six years or more building and shipping ML systems that customers used and that you were responsible for end-to-end, from offline metric to user-visible behaviour.
• Strong on at least one of: federated or edge ML systems; evaluation and orchestration; simulation-based testing and benchmarking; compiler-style configuration systems, or anything in that family.
• An instinct for making things simpler alongside making them more capable. We hire people who reduce complexity, not just add to it.
• Comfortable in both owning a multi-surface engineering programme and deepen one component.
• The kind of senior who unblocks others by default.
• Fluent in PyTorch and modern serving infrastructure; comfortable engaging with the front-end team on Rust and React adjacent product work even if not writing it.

Nice to have

What we offer

• Base salary of £95,000 – £140,000 annually (dependent on experience).
• Meaningful share-pool participation in a UK-based deeptech company.
• Pension and standard UK benefits.
• A conference budget that funds at least one tier-1 venue per year as a co-author or first-author submission.
• Full access to Blankstate's research compute. No notebook-only roles.
• A direct line to the cofounder, the operational research-leadership seat for the next two years, and a clear path to grow alongside the Scientific Director once that seat is filled.
