About The Company
LaunchDarkly is the runtime control platform for releases, AI behavior, and customer experiences in real time with no redeploys required. As the pioneer of feature management, LaunchDarkly introduced a new way for engineering teams to separate code deployment from feature release, allowing organizations to innovate faster while reducing risk in production. Today, LaunchDarkly’s control plane enables teams to govern how software and AI-powered features behave after code is deployed. By progressively rolling out changes, targeting specific users or environments, monitoring performance, and instantly rolling back when needed, organizations can safely operate at global scale. This approach empowers DevOps, product, and business teams to deliver better customer experiences while maintaining reliability and control. LaunchDarkly processes more than 40 trillion feature flag evaluations per day and serves over a quarter of the Fortune 500. Founded in 2014 in Oakland, California by Edith Harbaugh and John Kodumal, LaunchDarkly has been named to the Inc. 5000, the Forbes Cloud 100 for five consecutive years, and Fast Company’s Most Innovative Companies list.
About the Role

About the Job:

As an SDK Engineer on LaunchDarkly’s AI Configs team, you'll build the primary touchpoint that our customers interact with on a daily basis. You’ll drive the development of the SDK that enables customers to control, monitor, and optimize their GenAI functionality. You’ll primarily work in Python and Typescript, but you’ll also be exposed to other languages in LaunchDarkly’s stack. When working on our SDKs, you’ll contribute 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’s AI Configs team is on a mission to manage the complete software development lifecycle for GenAI features, from configuring to benchmarking to observing and beyond. This team has a huge opportunity ahead of it; we're growing fast and we need your help writing the next chapter in our story.

Responsibilities:

  • Contribute to the development of our open-source AI SDKs, including implementing new features and keeping up-to-date with the latest development practices

  • Collaborate with our engineering and product teams to drive the implementation and release of major features

  • Drive key improvements to key developer experience touch points within the SDK

  • Actively maintain our open-source repositories

  • Identify areas of improvement and advocate for best practices

  • Have an active voice in shaping both technology and product decisions

Qualifications:

  • Demonstrable experience building libraries and packages used by other developers

  • 5+ years experience with Python and Typescript

  • Experience working with AI SDKs such as the OpenAI and Vercel AI SDKs

  • Strong computer science fundamentals

  • Committed to working in a communicative, collaborative environment

  • 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 writing production-ready code with emphasis on quality and maintainability

  • Experience contributing to open-source software

About LaunchDarkly:

Modern software delivery was supposed to be the foundation for a thriving digital business but reality has proven otherwise. Slow, inefficient development cycles, costly outages, and fragmented customer experiences are preventing developers from building their best software. The LaunchDarkly platform helps developers innovate on new features faster while protecting them with a safety valve to instantly rewind when things go wrong. Developers can target product experiences to any customer segment and maximize the business impact of every feature. And by gradually rolling out new application components, they escape nightmare "big-bang" technology migrations. 

The LaunchDarkly platform was built to guide engineers to the next frontier of DevOps by:

  • Improving the velocity and stability of software releases, without the fear of end customer outages
  • Delivering targeted experiences by easily personalizing features to customer cohorts
  • Maximizing the business impact of every feature through the ability to experiment and optimize
  • Coordinating the release and optimization of software to provide consistent experiences across mobile platforms and device types
  • Improving the effectiveness and productivity of engineering teams, by providing insights into engineering cadence and stability
