AI models: OpenAI, Anthropic, Google. Benefits include unlimited AI token budget, take-what-you-need vacation, healthcare/vision/dental, daily office meals and snacks. REQUIREMENTS: - Exceptional software fundamentals: system design, architecture, data modeling, API design - Strong code quality and codebase management, including monorepo experience - Proven ability to scale large, data-intensive, multi-tenant distributed services - Track record of independently shipping features with direct customer impact - Deep expertise in core stack: TypeScript, React, containers, Postgres, Redis, Temporal - Proficiency with AI tools and ability to leverage frontier AI coding in your workflow - Senior or Staff-level experience (role explicitly targets this level)
