About the role

The Problem

36 million businesses in America need insurance—it’s not optional. 77% are underinsured. 40% have no coverage at all. The distribution system failed them: too slow, too opaque, too confusing.

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.

The Role

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.

What You’ll Do

Build AI agents that run the business — Lead qualification, customer service, underwriter follow-up—all without human intervention
Create workflow orchestration — Document retrieval, carrier API calls, compliance checks, human review—coordinated across thousands of concurrent transactions
Ship voice AI that actually works — Handle skeptical business owners asking “wait, what does that actually cover?”
Build systems that compound — Every decision gets traced; every outcome feeds back; the AI gets smarter with each interaction

You Might Be a Fit If…

You write code with AI (Cursor, Claude Code, Windsurf) and can manage multiple coding sessions

You’ve shipped AI to production—real systems serving real users

You’re full-stack by instinct (frontend, backend, infrastructure)

You ship fast and iterate—meaningful features in days that others take months on

You’re 1-4 years into your career
