About the role

About the Job: LaunchDarkly is hiring a Backend Software Engineer to join our Flag Delivery team.
The team is very senior, and this role is for someone eager to learn and grow as the team balances modernization with resilience and operational improvements.
About LaunchDarkly: Modern software delivery was supposed to be the foundation for a thriving digital business but reality has proven otherwise.

Build, improve, and operate backend services that power LaunchDarkly's Flag Delivery systems.
Contribute to systems that support streaming and polling delivery models for LaunchDarkly SDKs.
Debug production issues, improve service reliability, and help the team maintain strong standards around latency, availability, observability, and operability.
Collaborate closely with partner teams including SDK, Platform, SRE, Security, and Enterprise to deliver improvements across the broader platform.
Participate in the on-call rotation and take ownership of the systems you help build.
In this role, you'll build and improve backend services that sit directly on LaunchDarkly's critical delivery path, partner closely with SDK, Platform, SRE, and Security, and work on real-time production systems at scale.
Slow, inefficient development cycles, costly outages, and fragmented customer experiences are preventing developers from building their best software.
