Key Responsibilities & Objectives
- 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).
Required Qualifications & Candidate Blueprint
- Have strong experience with modern frontend stacks (React, TypeScript) and a high bar for UI craft.
- Have experience with developer tools or IDE extensions (nice-to-have).

About the Role
We’re hiring a Frontend Software Engineer to build a top-tier desktop experience and push forward the interface for working with agents. This is a craft-heavy role: you’ll partner closely with design to prototype, iterate, and polish new interaction models — then turn them into reliable, high-performance product.
You’ll help define what great looks like for “human ↔ agent” collaboration: what belongs in the UI, how state is represented, how progress and uncertainty are communicated, and how users stay oriented across long-running and multi-step work.
What You’ll Do
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.
You Might Thrive Here If You
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).
