About LaunchDarkly:

LaunchDarkly is a Feature Management Platform that serves trillions of feature flags daily to help software teams build better software, faster. Feature flagging is an industry standard methodology of wrapping a new or risky section of code or infrastructure change with a flag. Each flag can easily be turned off independent of code deployment (aka "dark launching"). LaunchDarkly has SDKs for all major web and mobile platforms. We are building a diverse team so that we can offer robust products and services. Our team culture is dynamic, friendly, and supportive. Our headquarters are in Oakland.

At LaunchDarkly, we believe in the power of teams. We're building a team that is humble, open, collaborative, respectful and kind.

We encourage you to apply to this role even if you don’t think you meet 100% of the qualifications outlined above. We can find out together if it's the right match for your skillset.
