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.

• 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

• 8+ 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:
