About the role

Frontend-focused role building the Codex desktop app and IDE extension, partnering with design to prototype and polish new interaction models for human ↔ agent collaboration, and owning frontend architecture and delivery across the Codex desktop app and IDE extension.

Responsibilities

  • Build and ship polished, high-performance UI across the Codex desktop app and IDE extension.
  • Partner tightly with design to turn prototypes into production-quality experiences (layout, motion, typography, interaction details).
  • Iterate on future interfaces for interacting with agents: delegation, task timelines, status/progress, handoffs, review, and control surfaces.
  • Own frontend architecture decisions (component systems, state management, navigation, rendering performance).
  • Improve quality and reliability through testing, instrumentation, and thoughtful UX for failure modes.
  • Collaborate with platform/model/backend partners to integrate new capabilities into cohesive product flows.

Qualifications

  • Have strong experience with modern frontend stacks (React, TypeScript) and a high bar for UI craft.
  • Love design engineering: sweating the details while keeping velocity.
  • Have built desktop-caliber product experiences (Electron or similar), and care about performance, responsiveness, and “it just feels right.”
  • Enjoy exploring ambiguous problems and iterating rapidly with design and product.
  • Think in end-to-end workflows, not isolated screens.
  • Have experience with developer tools or IDE extensions (nice-to-have)
