About Runloop
Runloop is pioneering the next generation of AI-powered software engineering. Our platform empowers developers to build, scale, and optimize AI coding solutions-accelerating how software gets built, maintained, and evolved.
We're a tight-knit, senior team of former Google and Stripe engineers, deeply focused on the hard problems of productionizing AI systems for real-world development.
The Role
We're looking for an experienced Software Engineer to join our Infrastructure team. You'll help build the robust, scalable, and secure foundation that powers Runloop's core platform-supporting the AI agents that assist software developers in real time.
You'll get to work hands-on with cutting-edge tech like MicroVMs, Kubernetes, AWS, and GCP-while collaborating closely with product engineers to support developer-facing systems at scale.
What You'll Do
Location
This is a hybrid role based in San Francisco. We work from the office 4 days/week, with optional WFH on Fridays.
Interested?
If you're excited to build the backbone of the future of AI-assisted software development, we'd love to meet you.
Apply now and help us redefine how code gets written.
