## About the role

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.

## What they're looking for

- 6+ years of professional backend engineering, with significant work on distributed or high-throughput production systems
- Track record designing, building, operating, and debugging reliable, low-latency services
- Strong production ownership, including on-call experience and a focus on reliability and observability
- Proficient in at least one backend language (Go, Rust, Python) and comfortable on a cloud platform (AWS or equivalent)
- Hands-on with infrastructure-as-code (Terraform or equivalent) and observability tooling (Datadog, Prometheus, New Relic)
- Deep grasp of distributed-systems fundamentals: concurrency, partitioning, retries, idempotency, backpressure, and failure handling
