Note: The job is a remote job and is open to candidates in USA. LaunchDarkly builds a software delivery platform that helps engineering teams release features safely, target customer experiences, and improve development velocity. The Senior Full Stack Engineer will own enterprise features end to end across Go backend and TypeScript/React frontend, focusing on governance, scalability, APIs, resilience, customer needs, and operational excellence.
Responsibilities
- Own features end to end: problem framing with your PM and designer, technical design, implementation across backend and frontend, rollout, and the operational life of the thing after it ships
- Design for enterprise constraints from the start. Permissions and access control, approval and audit requirements, data residency and regional isolation, and the behavior of the system when a region or dependency is degraded
- Find and fix scalability and performance limits before customers do. Identify where a current design stops holding at the top end of our customer base, quantify it, and lead the work to change it
- Make LaunchDarkly manageable at fleet scale. Extend our public API, Terraform provider, and configuration surfaces so a platform team can operate LaunchDarkly as infrastructure rather than click through it
- Work directly with customers. Join escalations and discovery calls, read the support and account signal, and turn a specific customer's problem into something that serves the whole segment rather than a one-off
- Raise operability of what the team owns. Observability, runbooks, and participation in the on-call rotation, plus the follow-through after an incident
- Drive alignment beyond your own team. Enterprise depends on and is depended on by several other teams, so surfacing a misalignment early and getting the right people in a room is a real part of the job at this level
- Mentor and review. Give substantive review on specifications and pull requests, including for engineers on neighboring teams, and help newer engineers get faster
Skills
- 6+ years of professional software engineering experience, with a track record of features you drove from design through production
- Genuine full stack ability. Strong in a statically typed backend language and comfortable owning frontend work rather than handing it off. Our stack is Go on the backend and TypeScript and React on the frontend
- Experience building for enterprise customers. Multi-tenancy, roles and permissions, SSO and identity, audit logging, approval workflows, or compliance requirements in a production product
- Demonstrated work on scale and performance problems: finding a bottleneck, measuring it, and changing the design rather than tuning around it
- API design judgment. You have built interfaces other engineers depend on and have dealt with the consequences of getting one wrong
- Comfort talking to customers. You can sit in a call with a large customer's platform team, understand what they actually need underneath what they asked for, and come back with something more general than the request
- A collaborator across time zones. Some of your teammates and stakeholders are in EMEA, and you are willing to flex occasionally to work with them properly
- Clear writing. Design documents and written decisions are how this team stays aligned across regions
