Staff Frontend Engineer, Feature Management

LaunchDarkly is hiring a Staff Frontend Engineer to own the quality and consistency of the core flag surfaces: the flag list, flag targeting, segments, and contexts. These surfaces grew up across several teams over several years, and the role is about bringing them into one coherent experience. The engineer works from the product backwards, knowing the personas who operate these surfaces—platform engineers, product managers, release managers, support engineers, and developers who delegate flag work to agents—and telling which friction is worth fixing. The levers are the shared frontend foundations: the design system, interaction primitives, and platform capability pulled in from upstream.

• Own the consistency and quality of the core flag surfaces across teams.
• Set the direction for how shared interactions work and review what teams build on these surfaces.
• Set the agenda from customer evidence, working from support, sales, and usage signal rather than taste.
• Own LaunchPad, the design system, as a lever on the product—including adoption, migration of call sites, lint enforcement, and a measurable adoption baseline.
• Track library and platform capability upstream and translate it into product improvement.
• Build interaction primitives for tables, filtering, sorting, comparison, and bulk change as shared capabilities, then migrate the product onto them.
• Prototype and land interaction patterns for hybrid human and agent workflows.
• Be the first line of defense on frontend performance for the highest-traffic surfaces.

• 10+ years of software engineering experience with deep frontend expertise, including a surface or system owned across multiple teams not managed.
• Strong with TypeScript and React; the stack is TypeScript and React on the frontend and Go on the backend.
• Experience owning a design system that was genuinely adopted.
• Product and UX judgment on top of engineering depth.
• A track record of cross-team influence without authority.
• Judgment about leverage.
• Real experience with data-dense enterprise product UI: large collections, filtering, permissions, environments, bulk operations, and performance work at customer scale.
• A point of view on agents in developer tooling, including building with LLM tool use, MCP, or agent frameworks in production.
• Excellent written communication.
