Job Overview

About the Job: LaunchDarkly is hiring a Backend Software Engineer to join our Flag Delivery team. Serving data to our customers is the core of our product and we’re expanding the team to add bandwidth and energy.

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.

Job Description

This role is a strong fit for an engineer who is excited by distributed systems, weird production behavior, and learning quickly on a senior team, and who already brings real production instincts, strong debugging judgment, and clear AI fluency in their engineering work.

Responsibilities: 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.

Work with technologies and patterns common to modern distributed backend systems, including caching layers, network services, concurrency, failure handling, and cloud infrastructure.

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.

Learn the existing architecture deeply and make pragmatic improvements that increase system clarity, performance, and maintainability.
