Job Description
Staff Frontend Engineer owning consistent flag-management surfaces for LaunchDarkly’s developer platform. Building design-system foundations, enterprise UI workflows, and agent-assisted product experiences.
Responsibilities:
- Own the consistency and quality of core flag surfaces across teams, including shared interaction direction and review of team implementations.
- Set the product agenda from customer evidence, personas, support, sales, and usage signals.
- Own LaunchPad, LaunchDarkly’s design system, including components, tokens, patterns, adoption, migrations, lint enforcement, and adoption measurement.
- Track upstream library and platform capabilities and translate them into product improvements.
- Build shared interaction primitives for tables, filtering, sorting, comparison, and bulk changes, then migrate the product onto them.
- Prototype and implement interaction patterns for hybrid human-and-agent workflows.
- Serve as the first line of defense for frontend performance on high-traffic enterprise surfaces.
- Collaborate closely with Design, Product, Enterprise Feature Management, and Foundation Feature Management teams.
Requirements:
- 10+ years of software engineering experience with deep frontend expertise.
- Experience owning a surface or system across multiple teams without directly managing them.
- Strong TypeScript and React skills.
- Ability to work across the frontend/API boundary; LaunchDarkly’s backend uses Go.
- Experience owning a genuinely adopted design system, including migration and enforcement.
- Strong product and UX judgment and ability to trace workflows end to end.
- Track record of cross-team influence without authority.
- Strong judgment about prioritizing high-leverage work.
- Experience with data-dense enterprise product UIs, including large collections, filtering, permissions, environments, bulk operations, and performance at customer scale.
- Production experience with LLM tool use, MCP, or agent frameworks, plus a perspective on agent-driven product design.
- Excellent written communication.
Benefits:
- Restricted Stock Units (RSUs)
- Health insurance
- Vision insurance
- Dental insurance
- Mental health benefits
