Build high-fidelity productivity infrastructure for a globally distributed workforce—software that operates quietly, reliably, and intelligently in the background.

Job Type: Full-time | Location: Remote

What You’ll Work On

  1. Architect and evolve a cross-platform desktop agent using Electron.js, optimized for performance and minimal resource footprint.

  2. Build real-time timekeeping systems with precise event tracking and background execution.

  3. Design and implement system-level signal collection (keyboard, mouse, app usage) with strong privacy and efficiency guarantees.

  4. Develop offline-first data pipelines with reliable background sync and conflict resolution.

  5. Integrate with distributed backend services and internal APIs to enable analytics and reporting.

  6. Continuously improve runtime performance, memory efficiency, and fault tolerance.

  7. Collaborate with product, design, and backend teams to ship features that directly impact user productivity.


What We're Looking For

  1. 3+ years building production-grade desktop applications with Electron.js.

  2. Strong proficiency in JavaScript/TypeScript and Node.js.

  3. Experience designing cross-platform systems (MacOS + Windows) with consistent behavior.

  4. Hands-on work with real-time tracking, event streams, or activity monitoring systems.

  5. Familiarity with OS-level APIs for capturing user/system interactions.

  6. Deep understanding of performance optimization in desktop environments.

  7. Strong debugging skills and ability to reason about edge cases in distributed/offline systems.


Preferred

  1. Experience building productivity, monitoring, or telemetry-driven applications.

  2. Knowledge of native OS integrations (permissions, background processes, system hooks).

  3. Understanding of security and privacy considerations in user activity tracking.

  4. Familiarity with auto-update systems and release management in Electron.

Candidate profile

As a Software Engineer focused on desktop systems, you’ll help design and scale a cross-platform time intelligence application (MacOS + Windows) used daily by thousands of professionals.

Working environment

US-based technology company building AI-powered solutions that help organizations streamline and automate their hiring processes. Their platform combines artificial intelligence with modern software engineering to improve how companies discover, evaluate, and engage talent at scale.
