About the Job:
Software powers the world, and LaunchDarkly empowers teams to deliver and control it safely. As a Senior Software Engineer on the Flag Delivery team, you will own the critical-path systems that stream feature-flag configuration to every connected SDK globally, in near real time. These systems run at high scale and have to stay reliable, low-latency, and correct; when they fail, customers lose control of their features.
This is added headcount on a growing team. You will work on the next generation of the flag-delivery architecture, streaming rollouts, and reliability and scale hardening. Our stack is Go, AWS, Terraform, and Datadog, but exact tool match matters less than deep backend expertise and a track record of owning production systems.
Responsibilities:
•
Design, build, and operate the distributed systems that deliver feature-flag configuration to LaunchDarkly SDKs.
•
Own and improve the reliability, latency, and scalability of our streaming and polling infrastructure.
•
Debug and resolve complex production issues, sharing the team’s on-call rotation.
•
Partner with SDK, Core Product, and Data Platform teams on how flags reach customers.
•
Write maintainable, well-tested code and engage in code reviews, design reviews, and production-readiness discussions.
