Full Stack Engineer, Foundation

Responsibilities:

• Drive features from problem framing through design partnership, full-stack implementation, instrumentation, rollout, and experimentation. Each initiative should have a clear line of sight to a PLG metric.
• Build the next version of LaunchDarkly's onboarding, including agentic flows that work inside a developer's IDE and plug into MCP servers and LLM-powered tooling. The goal is customers with a useful flag running in production on day one.
• Instrument and analyze the growth funnel: signup, activation, first flag, first experiment, first paid conversion. Run experiments that move each step.

Qualifications:

• 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 using MCP servers, agent frameworks, or LLM tool-use.
• Comfort across the stack: strong with TypeScript and React on the frontend, able to hold your own in Go or Node on the backend.
