About the Team The Codex App team owns the desktop application and IDE extension that bring Codex into developers’ daily workflows. We build product experiences end-to-end, and we care equally about usability, performance, and reliability. Our stack is centered on a TypeScript/Node/Electron application that interfaces with external systems including the Codex CLI and an app server (Rust). Windows is a critical platform for our users — delivering a great experience means working across packaging, system integration, and varied developer environments, from native Windows setups to WSL-based workflows. About the Role We’re hiring a Full Stack Software Engineer to own and evolve the Windows experience for the Codex desktop app and IDE extension. You’ll work across UI → Node/TypeScript backend layers → IPC/process orchestration → integration with Rust services. This role also owns how the app installs, runs, updates, and interacts with the system across real-world Windows environments — including enterprise-managed machines, varied shell/toolchain setups, and WSL-based development workflows. This is a product-minded role: you’ll help define what reliable “human ↔ agent” collaboration looks like on Windows, and ensure it works in practice. What You’ll Do Build end-to-end features across the Electron app (UI + Node/TypeScript backend layers). Design robust integrations with the Codex CLI and app server (Rust), including process lifecycle, streaming output, and failure handling. Own IPC architecture and process orchestration (renderer/main boundaries, message schemas, cancellation, retries). Build and maintain Windows packaging and distribution pipelines (installers, code signing, auto-update). Ensure reliable operation across varied environments: native Windows WSL-based development setups multiple shells/toolchains (PowerShell, Git Bash, etc.) Manage filesystem and process boundaries between Windows and WSL environments. Improve reliability and debuggability through logging, tracing, crash reporting, and performance tooling. You Might Thrive Here If You Have strong TypeScript/Node fundamentals and enjoy owning product features end-to-end. Have experience building or distributing Windows desktop applications (Electron or similar). Understand Windows-specific packaging, signing, and update flows. Are comfortable spawning and managing native processes on Windows. Have experience with WSL interop (filesystem paths, process boundaries). Have worked in enterprise Windows environments (e.g., proxies, Defender, GPO constraints). Are interested in IPC patterns and local orchestration of long-running tasks. Bring strong product judgment and enjoy making complex systems feel dependable and fast.
