Founding Product Engineer (AI security startup)
Jack
San Francisco, CA, United States
We're recruiting a Founding Product Engineer for a seed-stage AI security startup in San Francisco.
Their AI risk platform is already used by Fortune 500 enterprises and a major pro sports team to assess and monitor the risk that comes with the AI tools they roll out.
You'd be the first engineer who works only on the customer-facing product, and you own it end to end. That means figuring out what to build, building it, and seeing how customers actually use it.
What you'd own
- Making the platform easy for every team inside a big enterprise to use, well beyond the workflows it supports today
- New product experiences built on top of the AI risk data for new use cases
- Improving existing features and UI end to end across Python, Postgres and React
- Digging into customer data and feedback to decide what gets built next (a good chunk of this is PM-type work)
- Working closely with engineering and sales, and meeting customers when it makes sense
Stack: Python, React, PostgreSQL.
You're probably a fit if you have
- 1 to 5 years as a product engineer or full-stack engineer
- Real product intuition.
You care about the customer's problem, not just the ticket
- Clear communication and a high sense of ownership
- Bonus: you've been a founder or founding engineer, or you've built user-facing side projects people actually used
You don't need an AI security background.
You do need real interest in learning the space.
Who this isn't for
- Anyone who can't be in the San Francisco office 5 days a week
- Engineers who'd rather only take tickets and never talk to customers
Pay: $130K to $180K base plus meaningful founding equity.
Relocation help is available case by case.
Visa: They can't sponsor visas for this role.
