Responsibilities
- Build, improve, and operate backend services that power LaunchDarkly’s Flag Delivery systems.
- Collaborate closely with partner teams including SDK, Platform, SRE, Security, and Enterprise to deliver improvements across the broader platform.
Requirements
- 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.
- 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:
- Work with technologies and patterns common to modern distributed backend systems, including caching layers, network services, concurrency, failure handling, and cloud infrastructure.
- Use AI as part of your engineering workflow with sound judgment, including knowing when to use it, how to direct it effectively, and how to verify or reject its output.
- Reason clearly about code, architecture, and whole-system behavior even when AI is in the loop. About You:
- You already use AI regularly in your engineering work and can explain how, when, and why
- Strong programming skills in Go, Java, Rust, or a similar backend language; today the team primarily uses Go, with some Rust in the broader environment.
- Clear, existing AI usage in engineering work.
- Ability to use AI without surrendering technical judgment.
- Familiarity with distributed systems fundamentals such as caching, concurrency, failure modes, and reliability. •
- Strong collaboration and communication skills, with the ability to work well across engineering teams.
Experience
- 5+ years of backend software engineering experience. •
