Job summary

LaunchDarkly is seeking a Backend Engineer to help expand Vega, our AI-powered platform that surfaces insights and automates actions across LaunchDarkly products. This greenfield role focuses on building APIs, services, and agent infrastructure in Go, scaling data pipelines, and enabling AI-driven capabilities across Observability and Feature Management.

You'll own features end-to-end, design production-grade architectures, and collaborate across product, design, and engineering teams to drive

Qualifications

• 5+ years of professional software engineering experience, with a track record of shipping production-quality backend systems.
• Proficient in Go (or a similar language like Java, Rust, or C++) and experienced designing APIs and distributed services
• Experience building or integrating LLM-powered features, agents, or AI-driven workflows
• Experience with data-intensive systems—streaming pipelines, columnar stores (e.g., ClickHouse), or high-volume ingest is a strong plus
• Strong product instincts: you care about how your systems are used and can translate ambiguous requirements into clean, well-scoped solutions
• Collaborative and communicative—you work well across teams and functions, and you're comfortable navigating ambiguity
• Familiarity with LaunchDarkly, feature flagging, or observability tooling is a plus

• Own features end-to-end: from prototype and API design through production rollout and iteration
• Operate high-throughput data systems and keep them reliable, performant, and cost-efficient at scale
• Collaborate cross-functionally with product managers, designers, and engineers across Observability and Feature Management
• Participate in architecture discussions and technical design reviews, contributing to sound trade-off decisions
• Write well-tested, maintainable code and promote best practices for quality, observability, and reliability
• Mentor teammates and contribute to a collaborative, high-trust engineering culture
• Participate in on-call rotations and take ownership of production reliability for your features
