Software Engineer, Web Layer

About the Team

The Codex Web Layer team provides the web-based systems and user experiences for Codex across the entire stack from the Electron-like application framework that powers the application to the user-facing in-app browser.

About the Role

In this role you will be responsible for designing and implementing infrastructure and features end-to-end for the Codex desktop client application. You will help define what it means to be a hybrid agentic/interactive web browser. The team embodies full stack development from the lowest-level OS integration to the highest-level interaction design.

This role is based in San Francisco. We use a hybrid work model of 3 days in the office per week and offer relocation assistance to new employees.

In this role you will:

• Partner closely with product and design to conceive design and build features for Codex web browsing features on macOS and Windows. This role will focus mostly on the backend C layer and Chromium but many features cross the full stack including some TypeScript.

• Partner with the wider Codex team to deliver a high-performance stable and secure application platform for client development. This includes API design and implementation (mostly in C) and the infrastructure that supports deploying it (in Python TypeScript and agentic skills).

• Work with a small experienced team of engineers on this critical and rapidly growing product.

You might thrive in this role if you:

• Have significant experience building technically complex features end-to-end.

• Are a strong C developer especially with experience in browser environments like Chromium and Electron. Since this role is more backend focused general knowledge of web development and TypeScript is helpful but not required.

• Thrive in a fast-paced ambiguous environment.

• Communicate clearly and concisely across many different roles in the organization.

• Are self-directed identifying important work and executing it end-to-end.
