Frontend Engineer, Guarded Releases

Launch Darkly is looking for an experienced Frontend Engineer to play a key role in shaping the future of software delivery on the Guarded Releases team. The Guarded Releases team is focused on making every release safer, faster, and more reliable. Our mission is to redefine how software is released: automating release processes, measuring the real‑time impact of feature rollouts, and simplifying debugging when things go wrong.

We are solving critical challenges in modern software delivery: reducing the time it takes to detect regressions, automating responses to minimize risk, and eliminating manual effort. We extensively use the products we build, allowing us to create our own ideal release process while shaping the developer experience for teams across the industry.

If you’re interested in building the systems that help software teams ship safely at scale, we’d love to work with you.
