Wait…
Over 90% of commercial insurance is still human-led. We’re building the inverse: 90%+ AI-led, pushing toward the higher 90s. Not by patching legacy workflows—by building AI that makes humans more effective, improves the customer experience, and eliminates friction at every step.
We’re adding ~1,000 customers per month. We’ve grown 100x since last year. We’re looking to do even more this year—and that’s why we’re hiring.
You’ll build the AI systems that operate Harper—not features, the actual intelligence that runs the company.
The Thesis
This is full-stack in the truest sense: the interface a customer sees, the backend that powers their entire journey—application, business data, history, ongoing service—and the AI layer that makes decisions. Your code ships to production and generates revenue the same week you write it.
You’ll build AI agents, workflow orchestration, and voice AI that actually works. Not demos—real systems serving real users at scale. You work directly with founders. No committee. No approval chain. You build it, you ship it, you own the outcome.
To Apply
If you want to build something that’s never existed, ship code that runs a real business, and work with people who show up with the same intensity every day—send your resume and a link to something you’ve built.
