Product Engineer

What You Will Own

The chat truth experience, end to end. You own it the way a founder owns a product — the experience, the metrics, the roadmap, the build — and you own falsifiable outcomes, each with an evidence test a stranger could run.

Product calls in the gray area. Most decisions on a consumer surface have no clean data answer: when does a confidence indicator build trust, and when does it create doubt? When is "don't buy this" the right answer to render boldly? You weigh the data, the user, and your taste — and you decide.

The Mockup-Before-Code Gate

You run the discipline that everything gets seen before it gets built: mockup first, spec locked, then the agents build. You own the spec quality that determines whether a long unattended run lands clean or wanders.

Quality and Eval Gates for Agent-Written UI Code

You define what "correct" means for a streaming, citation-bearing interface and make that definition executable — so the review wall scales with the velocity. Almost no one shipping with agents has built this; you will.
