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.

Foundation owns the first mile of the developer journey - the moment a developer finds LaunchDarkly, creates an account, ships their first flag, and starts to see real value.

We are responsible for turning initial interest into long-term adoption, and for the PLG metrics that track how well we do it: time to value, activation, developer-to-paid conversion, and the path from a free trial to a paying customer.

We are building the next version of this experience around agents.

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.

That shape of product requires engineers who already live in this space.

We want someone who has shipped features on top of MCP servers, who is comfortable designing around model capabilities, and who has a real point of view on where AI meaningfully changes a product and where it just adds surface area.

Modern software delivery was supposed to be the foundation for a thriving digital business but reality has proven otherwise. Slow, inefficient development cycles, costly outages, and fragmented customer experiences are preventing developers from building their best software. The LaunchDarkly platform helps developers innovate on new features faster while protecting them with a safety valve to instantly rewind when things go wrong. Developers can target product experiences to any customer segment and maximize the business impact of every feature. And by gradually rolling out new application components, they escape nightmare "big-bang" technology migrations.

The LaunchDarkly platform was built to guide engineers to the next frontier of DevOps by:

Improving the velocity and stability of software releases, without the fear of end customer outages

Delivering targeted experiences by easily personalizing features to customer cohorts

Maximizing the business impact of every feature through the ability to experiment and optimize

Coordinating the release and optimization of software to provide consistent experiences across mobile platforms and device types
