LaunchDarkly is seeking a Senior Engineering Manager to lead the SDK team, responsible for the developer experience across every platform. The team builds and maintains 35+ open-source SDKs, OpenFeature providers, event-streaming libraries, contract tests, release tooling, and the Relay Proxy—code that developers integrate directly into their applications and the primary way customers experience LaunchDarkly daily.
The SDKs are feature-rich agents that bring LaunchDarkly's capabilities into a wide range of languages, frameworks, and platforms, with deep focus on performance, concurrency, resiliency, and idiomatic developer experiences. Trillions of feature flag evaluations run through code this team ships, giving the team direct impact on how safely and confidently engineering organizations deliver software.
You will lead a senior, polyglot team working at the intersection of developer tooling, distributed systems, open source, and software delivery. This is an opportunity to shape a highly visible portfolio, influence how developers integrate with LaunchDarkly, and help define what great developer infrastructure looks like at scale.
Key responsibilities include:
- Lead and develop a team of senior engineers, providing coaching, feedback, and career growth opportunities
- Own prioritization and intake for the SDK portfolio, balancing feature work, maintenance, security, and customer escalations across 35+ SDKs and the Relay Proxy
- Partner with Product Management to define and deliver the SDK and Relay Proxy roadmap, including version support and deprecation policy
- Guide technical tradeoffs across languages and platforms, ensuring SDKs remain idiomatic, performant, and resilient
- Represent SDK engineering with customers, Support, Solutions, and Sales; communicate roadmaps, risks, and progress to engineering leadership
- Drive operational excellence in release quality, observability, and incident response
- Build team working norms that promote collaboration, reduce silos and bus factor, and keep engineers engaged
- Participate in hiring to grow the team and raise the engineering bar
Requirements:
- 5+ years of experience in a formal engineering management role, including managing senior engineers
- Experience leading teams that build developer-facing software: SDKs, client libraries, public APIs, or open-source projects used by external developers
- Working familiarity with several programming languages and ecosystems, with judgment to guide technical tradeoffs in a polyglot codebase
- Proven ability to prioritize across many stakeholders and partner with Product Management to translate business goals into engineering plans with reliable estimates
- Track record of coaching and developing senior engineers, including performance management, career growth planning, and technical mentorship
- Excellent communication skills with technical and non-technical stakeholders, including customers
- Familiarity with observability practices and comfort with production incident response
- Experience contributing to or maintaining open-source software is a plus
