About the role
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 error handling.
- Own IPC architecture and patterns (renderer/main boundaries, message schemas, backpressure, safety, debugging).
- Build systems for orchestration: long-running tasks, incremental progress updates, cancellation, retries, and state synchronization.
- Improve reliability, observability, and performance (logging/tracing/metrics, profiling, crash/debug tooling).
- Partner with design and product to turn ambiguous needs into crisp, shippable workflows.
You Might Thrive Here If You
- Have strong TypeScript/Node fundamentals and enjoy owning product features end-to-end.
- Have experience with Electron or desktop app architecture (renderer/main separation, performance pitfalls, packaging/release concerns).
- Are comfortable integrating with native processes/services (e.g., Rust) and designing clean, testable boundaries.
- Know (or are excited to learn) IPC patterns and distributed-systems-like thinking applied locally: message ordering, buffering, backpressure, retries, idempotency.
- Bring strong product judgment and enjoy iterating based on real usage and feedback.
- Have experience with developer tools, CLIs, or IDE integrations (nice-to-have).
