Senior Full Stack Engineer, Enterprise, Feature Management

About the Job:

The Enterprise team builds LaunchDarkly for the customers who push it hardest. Global banks, national health systems, and Fortune 100 manufacturers run us across thousands of engineers and tens of thousands of flags, inside audit and change control processes most software never meets.

That scale breaks things that work fine everywhere else. A permissions model designed for a hundred users can be the reason a rollout to twenty thousand stalls. Volume creates a different class of problem, where a flag payload that costs nothing to deliver once gets expensive across a large service fleet. Your work is to find where a current design stops holding and build what replaces it. You will own that end to end, in Go on the backend and TypeScript and React on the frontend.

The problems fall into a few areas:

• Governance and access control. Roles, permissions, approvals, and audit trails that satisfy a regulator.

• Scale and performance. Finding the limit before the customer does, then changing the design rather than tuning around it.

• Programmatic control. Our public API, Terraform provider, and configuration surfaces, so a platform team can run LaunchDarkly as infrastructure.

• Resilience under real constraints. Data residency, regional isolation, and sane behavior when a dependency is degraded.

Enterprise runs closer to its own business than most product teams. Roughly half the roadmap traces back to requests from named customers, so you will often know who is waiting on your work and what it unblocks for them. You will speak with those customers directly. The other half is larger forward-looking work, where the brief is a capability our biggest customers will need rather than one they have already asked for.
