EngineeringFullstack Developer

We’re a fast-growing startup rethinking how back-office work gets done in financial services. Our first product helps automotive lenders resolve insurance claims more effectively, delivering better outcomes for both lenders and consumers through automation and AI. Small improvements can unlock significant value for our customers. Along the way, we’ve helped consumers avoid millions in debt.

Our work spans a wide range of engineering challenges — from building core application features and integrations, to designing reliable infrastructure, to creating AI/LLM-driven workflows that automate complex processes.

We’re an early stage venture-backed startup and scaling quickly. We’re scrappy, intentional, and focused on solving real problems for our customers. We bias toward shipping, learning fast, and building solutions that work in the real world.

Our headquarters is in New York City, and our team is distributed.

We’re backed by leading investors including 81 Collection, Better Tomorrow Ventures and Capital One Ventures.

We’re looking for a Full Stack Engineer to join our team. You’ll work across the stack, own projects end-to-end, and make foundational technical decisions that will shape our product and culture for years to come.

Some of your work will involve AI/LLM-based systems, but just as much will involve building the surrounding product and infrastructure that makes those systems valuable to our customers. If you enjoy tackling different kinds of problems, moving quickly, and taking ownership, this role is for you.
