About the company

Our client is a fast-growing software company.

The role

Raydar is recruiting for this role on behalf of our client. Contribute to a desktop software product that runs on multiple operating systems, writing code that spans the user interface and low-level native layers. You will take features from concept to release, add AI-driven capabilities, and have a voice in technical decisions on a small, close-knit engineering group.

What you'll do

  • Build and maintain key capabilities of a desktop application used across operating systems.
  • Take full responsibility for delivering features, covering both interface work and native components.
  • Create and connect functionality driven by large language models.
  • Work alongside teammates on platform-specific native code for Windows and macOS.
  • Weigh in on system architecture and help set engineering direction.

What we're looking for

  • A track record of taking product features from idea to launch in a rapidly growing startup or a large, fast-moving technology company, on products with real impact.
  • Exceptional depth in one area you care deeply about, shown through things like following AI developments, working with language models or open-source contributions.
  • Skill at describing technical choices in plain language to people outside engineering, and willingness to think aloud while solving problems.
  • A team-first attitude suited to a small, tightly knit group.
  • Meticulous habits and real pride in delivering polished, high-quality work.
  • A hands-on, accountable mindset with readiness to take on any task that moves the team forward.

Bonus points

  • Working knowledge of TypeScript with React and Node.js, plus Swift or C++ for native development.
  • Familiarity with building desktop apps using a web-based framework.
  • Hands-on work with AI-powered product features.
  • Background at consumer productivity software companies.
  • Prior experience founding a company or working at an early-stage startup.
  • Health, dental and vision coverage
  • Flexible time off and parental leave
  • Relocation support

Location and work model

  • San Francisco, California, United States
  • On-site, 5 days per week in office
  • Full-time
