Senior Staff Product Engineer

• Built and shipped production systems end-to-end, from design through rollout, monitoring, and iteration, in settings where correctness, performance, and resource efficiency mattered.
• Designed testing and observability that made complex behaviour understandable, debuggable, and safe to evolve.
• Worked effectively in a polyglot environment, choosing the right tool for the problem and picking up unfamiliar languages, domains, and codebases fast.
• Strong systems experience, for example in Rust, C/C++, or Python.
• Shipped work outside your strongest layer of the stack when the problem needed it, picking up the front end, the data layer, or the infrastructure rather than waiting for someone else to.
• Used AI tools as a serious part of how you build, with the judgement to direct, review, and stand behind what they produce.
• Carried product and design judgement into your engineering work, shaping the solution rather than only implementing a spec and making sensible calls under ambiguity.
• Owned outcomes beyond your immediate task, taking decisions rather than escalating them.
• At Level 5: set technical direction on a hard problem other engineers built on, and been judged on whether you made them faster and safer rather than on the size of your team.
• At Level 5: held a quality bar across other people's work without becoming the gate they wait on.
• At Level 5: led cross-cutting or decoupling work that teams adopted because it was the best path, not because it was mandated.
