Frontend Software Engineer, Codex App

About The Team

The Codex App team builds and maintains the Codex desktop app and IDE extension — the primary ways developers interact with Codex. Our goal is to make AI feel like a real software engineering teammate inside real workflows: editing code, running tasks, reviewing changes, and coordinating long-running work.

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.

• 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.

• Have strong experience with modern frontend stacks (React, Type Script) 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).
