[Remote] Full Stack Engineer, Foundation

Note: The job is a remote job and is open to candidates in USA. LaunchDarkly is hiring a Full Stack Engineer for the Foundation team. The role involves partnering closely with various teams to enhance the developer onboarding experience and improve product-led growth metrics.

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
• Ship MCP server capabilities and agent skills that extend LaunchDarkly into the tools customers already use
• Partner closely with our PM (Natalie Friedman), design team, and data analyst to turn qualitative signal from self-serve customers into shippable experiments
• Dogfood LaunchDarkly. Use flags, guarded rollouts, and experimentation on your own work. Give the product team real feedback on the developer experience
• As part of our you-build-it-you-run-it culture, all developers may be responsible for supporting applications in production, including on-call

Skills

• 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

Benefits

• Restricted Stock Units (RSUs)
• Health, vision, and dental insurance
• Mental health benefits
