Backend Engineer, Observability

About the Job: LaunchDarkly is looking for a Backend Engineer to help build and expand Vega, our AI-powered platform that surfaces insights and automates actions across LaunchDarkly products. This is a greenfield opportunity: you'll help evolve Vega from an Observability-focused assistant into a cross-product platform that serves Feature Management customers and powers a new, usage-based SKU. You'll build the APIs, services, and agent infrastructure that make Vega and the whole Observability platform broadly valuable—enabling capabilities like AI-driven dashboard creation, flag cleanup automation, and safe, sandboxed agent execution. You'll work primarily in Go services and data pipelines at significant scale, and collaborate closely with product, design, and other engineering teams to shape how AI capabilities land across LaunchDarkly. Additionally, you'll work on other Enterprise-grade capabilities for the Observability platform to help drive customer activation and success. Responsibilities: Design, build, and ship backend features across the Vega platform (APIs, Go services, agent infrastructure, and data pipelines) 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 an
