Software Engineer, SDKs
Location: Oakland, CA, USA, or remote
Company: LaunchDarkly

As a Software Engineer on LaunchDarkly’s SDK team, you will build the primary touchpoint that our customers interact with on a daily basis. You’ll work with multiple technologies across our 20+ SDKs while enabling customers of all kinds to feature flag their code. When working on our SDKs, you’d be contributing to much more than thin client wrappers. Our SDKs are feature-rich agents with strong emphases on performance, concurrency, and resiliency -- all while following idiomatic practices for their tech stack.

LaunchDarkly serves trillions of feature flags daily to customers all around the globe, and every flag is handled by our SDKs. This team has a major impact not only on our company, but on our customers (and their customers). We are growing fast and we need your help writing the next chapter in our story.


  • Contribute to SDK development for our supported platforms
  • Collaborate with our engineering and product teams to drive the implementation and release of major features
  • Actively maintain our open-source repositories
  • Write well-tested and well-organized production-quality code, with an emphasis on maintainability
  • Identify areas of improvement and advocate for best practices
  • Have an active voice in shaping both technology and product decisions

Basic Qualifications:

  • Polyglot background— fluency in at least one programming language, and an ability to context switch quickly between languages
  • Strong computer science fundamentals
  • Experience building and maintaining client applications or libraries
  • Strong communication and collaboration skills, a positive attitude, and empathy
  • Self‐starter and problem solver, willing to solve difficult problems and work independently when necessary
  • Strong testing background: experience building unit, integration, load tests, and benchmarks
  • Experience contributing to open-source software

About LaunchDarkly:

LaunchDarkly is a Feature Management Platform that serves hundreds of billions 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 are an equal opportunity employer and value diversity at our company. We do not discriminate on the basis of race, religion, color, national origin, gender, gender identity, sexual orientation, age, marital status, veteran status, or disability status. Don't let the confidence gap get in the way of applying! We'd love to hear from you.

We've partnered with KeyValues to help demonstrate the amazing culture we've built here at LaunchDarkly, find more info at
