Founding Product Engineer

Our Mission

Grit is on a mission to crush technical debt.
We believe that a big challenge in the next decade will be crumbling digital infrastructure. Our entire modern economy runs on code, but we haven’t developed appropriate tools to ensure software remains reliable over time.
Companies know that technical debt threatens the reliability of their services and slows down the pace of innovation, but struggle to find enough engineering talent to fix issues—most software maintenance today is still done manually and delayed as long as possible.
We believe there is a better way: we’re building AI bots that automatically maintain software through a combination of static analysis, our own query language, and machine learning.
Founders Fund and Abstract Ventures led our $7M seed round and we have many paying customers on our beta product.
We’re currently a small team of 3 engineers and are looking for others who are excited to make a big impact in a tight-knit team.

About the role

As a founding engineer at Grit, you will work on developing our end-to-end AI agents for software maintenance. You’ll be working on interfaces for AI to make changes and for humans to collaborate on those changes.
What’s the best way to present thousands of AI changes to humans for rapid review?
How can we discover the dependencies and requirements for running unit tests on a repository, even if there’s no configuration written?
How do we efficiently fork a running cloud instance to try two alternative migration strategies in parallel?
How can we build a caching file system to make it faster to check out repositories on new machines, without keeping permanent copies of customer code?
How do we stream results back to customers with minimal latency to allow live monitoring and intervention?
