Software Engineer, Fullstack

YCombinator - North America, 🇺🇸 US, San Francisco

Software engineering is being fundamentally transformed by AI, and we're building the tools to lead that shift. Aviator is creating the engineering productivity supertools that will define how the best teams build software in the AI era. We as strongly believe that we can provide developers with superpowers to build faster and better by solving the challenges that they face every day. We believe the future of software development isn't engineers replaced by AI—it's engineers supercharged by it. Small teams will ship what once required hundreds of people. Complex workflows that took days will complete in minutes. Backed by Y Combinator (S21), we're a small, focused team in San Francisco tackling one of the most important problems in tech: making every engineer dramatically more effective. Our platform already powers workflow automation at Slack, Figma, DoorDash, Square, and other industry leaders. MergeQueue eliminates merge conflicts and broken builds. FlexReview intelligently routes code reviews. And Runbooks—our newest product—is a collaborative AI agent platform that lets engineering teams automate complex workflows through natural language specs and shared context.
