The role We're looking for Technical Ex-Founders to join our Engineering team. If you wrote your company's early code, operated it through real user growth, and miss building and shipping more than you miss anything else about the founder job, this role is for you. Engineers who've founded or been the early technical leader at a startup tend to thrive at Slingshot because they get to work autonomously and own a large set of problems. They're product-minded owners by default, comfortable defining a problem, talking to users, building a solution, and iterating. We'll always have a place for smart and motivated technical people who have built and scaled something interesting.

What we look for You founded or was the early technical lead at a startup, wrote a meaningful share of the production code yourself, and operated it through meaningful user growth. 6+ years of (recent) hands-on engineering experience, with opinions on trade-offs and quality formed by having to live with your own decisions in production. Comfortable building inside AI/ML codebases. We don't need you to be an ML Engineer, but having an interest in AI helps! If this sounds like you, we'd love to hear from you. A short note about what you built last, what you'd want to build next, and links to anything you've shipped (projects, repos, writing) is more useful to us than a polished CV.
