Software Engineer, Web Layer

OpenAI•San Francisco, CA

7d•$255,000 - $405,000•Hybrid

About The Position

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.

Requirements

Significant experience building technically complex features end-to-end.
Strong C++ developer, especially with experience in browser environments like Chromium and Electron.
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.
Self-directed, identifying important work and executing it end-to-end.

Responsibilities

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.
