LaunchDarkly - Full Stack Engineer, Foundation

• 5+ years of full-stack engineering experience, with a portfolio of features you personally drove from idea to production. • Shipped AI-first features in production. You have used MCP servers, agent frameworks, or LLM tool-use in real products, not just demos, and you have a point of view on what works and what does not. • Comfort across the stack. Strong with TypeScript and React on the frontend. Able to hold your own in Go or Node on the backend. Our stack is TypeScript and Go. • Track record of moving product-led growth metrics. Hands-on experience with instrumentation, funnel analysis, and A/B testing. You think in leading and lagging indicators. • An experimentation habit. You are comfortable defining a hypothesis, wiring up a flag, running the test, reading the result honestly, and changing your mind. • Good instincts for what makes developer onboarding actually work. You have an opinion about when friction is a bug and when it is a feature. • A collaborative engineer who works well alongside product and design, communicates crisply, and enjoys the parts of the job that are not code. • Genuine interest in where AI belongs in a developer platform. You have thought about where agents help in your own workflow, and you want to bring that thinking into a product that a lot of developers will touch. • Target pay ranges based on Geographic Zones* for Level 3: • Zone 1: San Francisco/Bay Area or NYC Metropolitan Area, Boston, Seattle - $171,200 - $235,400** • Zone 2: Irvine, LA, Monterey, Santa Barbara, Santa Rosa, Austin, Portland, Philadelphia, Chicago - $154,100 - $211,860** • Zone 3: All other US locations - $145,500 - $200,090  ** • LaunchDarkly operates from a place of high trust and transparency; we are happy to state the pay range for our open roles to best align with your needs.
