Product Engineer, Core
About Key AI
Key AI is an AI-native professional intelligence platform. Think warm introductions, elite communities, and an AI agent (Kai) that actually works — for the kind of people who've built, led, and invested in the companies you've heard of. We're growing fast, shipping constantly, and building infrastructure that scales.
What you'll actually do
- Own features end-to-end — from product intuition design implementation metrics
- Sit with users, understand their problems, and translate that directly into what you build
- Debug infra at 2am if it matters, then walk a user through a new feature the next morning
- Work directly with Kush and Chris (the co-founders) on the hardest, most important problems
- Raise the bar for the eng team — mentor, review, and help the people around you win
Who we're looking for
- You've shipped products at scale at a startup — not just inside a big company
- You think in systems but obsess over the details that make products feel great
- You're as comfortable talking to users as you are debugging infrastructure
- You wear multiple hats not because you have to, but because you want to
- You have an eye for what great software feels like, not just what it does
- You want to unlock potential in the people around you
We're full-stack, AI-native, and moving fast. You should be fluent across the stack and have opinions about how to build things well. We care more about taste and track record than a specific language or framework. This is not a ticket-taker role. There's no PM handing you specs. You'll be expected to figure out what to build, build it well, and own the outcome after it ships.
