Senior Model Developer Sacramento, CA

Senior Model Developer job at Hyperexponential. Sacramento, CA.

At Hyperexponential, we're building the AI-powered platform that enables the world's most critical decisions in a $7 trillion industry: which risks to take, and how to price them. These are the decisions that shape real-world outcomes: whether rockets successfully launch into space, autonomous vehicles make it to market, or communities recover after major storms.

Until now, insurance has been making billion-dollar decisions using outdated tools. We're changing that. Our platform brings together data, AI, and human expertise to give insurers the fastest path from submission to decision. We help them move faster, act smarter, and take on more risk with confidence.

Backed by a16z, Highland Europe, and Battery Ventures, we're scaling globally. We are already trusted by nearly 50 of the world's largest insurers, with zero churn and billions in premiums flowing through hx.

What began as a single product in one market has rapidly evolved into a multi-product, multi-territory platform powering every stage of pricing and underwriting. AI is at the core of what we do, from building the world's first domain-specific AI peer programmer for insurance (think Git Hub Copilot with a PhD in actuarial science) to shaping agentic workflows that reinvent how this industry operates.

What makes hx different is the people who build it. Here, impact isn't tied to title or tenure. It's defined by the challenges you take on and the discipline you bring. Surrounded by peers who stretch you, you'll do the best, hardest work of your life in a company built to endure.

If that sounds like you, join us in building what comes next.

The Model Development team operates at the intersection of actuarial science and technology, enabling customers to unlock the full potential of hx Renew. We are the technical backbone of acostum .
