About the role

  • About the Job: LaunchDarkly is hiring a Full Stack Engineer for the Foundation team.
  • An onboarding agent meets a developer where they already work, reads the repo in front of them, and wires LaunchDarkly into their code in a few minutes.

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.
  • Dogfood LaunchDarkly. Use flags, guarded rollouts, and experimentation on your own work. Give the product team real feedback on the developer experience.
  • Slow, inefficient development cycles, costly outages, and fragmented customer experiences are preventing developers from building their best software.
  • Maximizing the business impact of every feature through the ability to experiment and optimize

Requirements

  • 5+ years of full-stack engineering experience, with a portfolio of features you personally drove from idea to 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.
  • Track record of moving product-led growth metrics.
  • Hands-on experience with instrumentation, funnel analysis, and A/B testing.
  • You are comfortable defining a hypothesis, wiring up a flag, running the test, reading the result honestly, and changing your mind.
  • You have an opinion about when friction is a bug and when it is a feature.
  • Modern software delivery was supposed to be the foundation for a thriving digital business but reality has proven otherwise.
  • 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.
