About the role

Key responsibilities & impact

Products end-to-end. You pick up a problem from product or a founder, write the spec yourself, decide what's in and out of scope, build it, ship it, and watch the metric. If the metric doesn't move, you figure out why and try again.
A direct line to product. No PM in the middle. You talk to product directly, push back when you should, and decide together what's worth building this week.
A team of agents. Claude (or whatever ships next month) handles code review, test generation, and boilerplate. You set the rules, review the reviews, and keep the bar for agent-produced code in your project above the company average.
Production health in your area. Bug count, incidents, test coverage, the long-term shape of the codebase agents are touching. You own the number, and we measure it.
Speed, measured. Lead time, throughput, agent cycle time. You'll have a personal baseline in week 2 and an improvement target by month 2. We don't count tickets closed.
Saying no. Roughly a third of what lands on your plate shouldn't get built. The right answer is often "let's run a 2-day experiment first" or "this doesn't move a metric we care about". Push back with reasoning, not instinct.
