Full Stack Engineer - Observability

<h4><strong>About the Job:</strong></h4> <p>LaunchDarkly is looking for a Full Stack 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.</p> <p>You'll build the surfaces, APIs, and agent infrastructure that make Vega and the whole Observability platform broadly valuable—enabling capabilities like AI-driven dashboard creation, flag cleanup automation, and sandboxed agent execution. You'll work across the full stack (React/TypeScript UI, Go services, data pipelines) 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.</p> <h4>What You'll Work On:</h4> <ul> <li>Expand Vega beyond Observability into Feature Management, including the flag cleanup agent as a cross-product capability</li> <li>Support enterprise capabilities for the Observability platforms: building data import and export pipelines to connect O11y to other platforms and enabling new customer workflows.</li> <li>Build a platform that other teams can contribute to—defining contribution patterns, shared infrastructure, and safe, sandboxed AI agent execution</li> <li>Enable dashboard creation via natural language prompts, using existing Vega infrastructure as a foundation</li> <li>Consolidate Vega usage into fewer, higher-value surfaces, enabling faster iteration and justifying a usage-based monetization model</li> <li>Run experiments to expose Vega to mainstream FM customers across core workflows, measuring adoption and informing monetization</li> <li>Partner with product and design to ensure Vega capabilities are intuitive, well-integrated, and impactful for end users</li> <li>Contribute to architecture decisions, code reviews, and engineering standards across the Observability and Vega teams</li> </ul> <h4>Responsibilities:</h4> <ul> <li>Design, build, and ship full-stack features across the Vega platform (UI, APIs, backend services, and agent infrastructure)</li> <li>Own features end-to-end: from prototype and API design through production rollout and iteration</li> <li>Collaborate cross-functionally with product managers, designers, and engineers across Observability and Feature Management</li> <li>Participate in architecture discussions and technical design reviews, contributing to sound trade-off decisions</li> <li>Write well-tested, maintainable code and promote best practices for quality, observability, and reliability</li> <li>Mentor teammates and contribute to a collaborative, high-trust engineering culture</li> <li>Participate in on-call rotations and take ownership of production reliability for your features</li> </ul> <h4>About You:</h4> <ul> <li>3+ years of professional software engineering experience, with a track record of shipping production-quality full-stack features</li> <li>Proficiency across the full stack—comfortable in TypeScript/React on the frontend and Go (or similar) on the backend</li> <li>Experience building or integrating LLM-powered features, agents, or AI-driven workflows</li> <li>Strong product instincts: you care about user experience and can translate ambiguous requirements into clean, well-scoped solutions</li> <li>Collaborative and communicative—you work well across teams and functions, and you're comfortable navigating ambiguity</li> <li>Familiarity with LaunchDarkly, feature flagging, or observability tooling is a plus</li> <li>Experience with usage-based product surfaces, experimentation platforms, or developer tooling is a plus</li> </ul> <div> <p class="p1"><strong>Pay:</strong></p> <p class="p1"><em>Target pay ranges based on Geographic Zones* for Level 2:</em></p> <ul class="ul1"> <li class="li1">Zone 1: <em>San Francisco/Bay Area or NYC Metropolitan Area, Boston, Seattle</em> - $136,500 - $187,660**</li> <li class="li1">Zone 2:<em> Irvine, LA, Monterey, Santa Barbara, Santa Rosa, Austin, Portland, Philadelphia, Chicago - </em>$122,800 - $168,850**</li> <li class="li1">Zone 3: <em>All other US locations - </em>$<span class=&q*
