Software Engineer I/II

Sunnyvale, CA or San Diego, CA or Seattle, WA

ABOUT US

E-commerce got real-time data infrastructure decades ago. Physical stores still have not. RADAR is changing that.

RADAR is building the data infrastructure layer for the physical world, starting with retail. Our hardware-enabled SaaS platform uses proprietary overhead sensors, software, and AI-powered analytics to locate every product in a store, continuously, down to the fixture.

RADAR is already deployed across 1,400+ stores with retailers including American Eagle Outfitters and Old Navy, processing tens of billions of real-world events every day, delivering 99%+ accuracy in complex, noisy environments - at fleet scale.

RADAR is one of the best-funded companies in retail technology, backed by a recent Series B financing at a $1 billion valuation. Inventory accuracy is only the beginning. We believe RADAR can become foundational infrastructure for the physical economy, powering new AI-driven commerce experiences across retail and beyond.

Join us if you want to work on a large, unsolved, technically challenging problem with an ambitious team building category-defining technology.

  • High Impact: You’ll make meaningful contributions from day one and help shape the future of our product and company.
  • Clear Communication: We value honesty, humility, and respectful dialogue—everyone’s voice matters.
  • Balanced Lives: We work hard, but not at the expense of well-being. We respect time, boundaries, and life outside of work.
  • Diverse Perspectives: We believe better ideas come from diverse backgrounds, experiences, and viewpoints.
  • Empathy-Driven Design: We build with deep respect for our end users, listening closely to their feedback and needs.

Form CC-305
Page 1 of 1

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
