About the role

Example projects include:

  • Building core client infrastructure: shared abstractions, build systems, and observability foundations.
  • Improving reliability and performance: eliminating memory leaks, crashes, and frame-time inconsistencies.
  • Designing instrumentation and telemetry systems for profiling, structured logging, and performance measurement.
  • Partnering with product teams to unlock faster release velocity—shipping updates to users daily.
  • Evaluating Electron vs. native approaches for critical code paths, guiding architectural tradeoffs.
  • Building internal tooling that enables other engineers to ship safely and quickly on the client platform.

You might be a fit if:

  • You have deep experience in client infrastructure—build systems, performance, distribution, or observability.
  • You’ve built or contributed to high-performance desktop applications, whether Electron-based or native.
  • You care deeply about performance, reliability, and developer experience, and have an eye for elegant systems design.
  • You thrive in environments that are fast-moving, collaborative, and product-focused.
  • You’re excited to push the limits of what’s possible in AI-driven developer tools.
