• Control who gets which features, with feature flags for staged rollouts and entitlements after rollout
• Improve the public interfaces developers and agents use: the SDKs, CLI, MCP servers and docs

Requirements:

• Have 5+ years of full-stack engineering on customer-facing products or high-throughput APIs
• Are strong in backend engineering, ideally in Python
• Have built and operated latency-sensitive, high-QPS APIs
• Have shipped production UI with a modern frontend framework such as React, Next.js or TanStack
• Have built data-heavy interfaces such as tables, charts and filters that stay fast
• Are effective in a mature, user-facing system
• Have strong product and design sense, for interfaces and for APIs

Benefits & Perks:

• Competitive compensation
