Senior Site Reliability Engineer

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. We are deployed across 1,500+ 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.

OUR VALUES

• Mission-Driven: We're transforming retail with cutting-edge technology and building something that truly matters. • Collaborative Team: We thrive on curiosity, shared goals, and solving complex problems together. • 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.

ABOUT THE JOB

RADAR runs data infrastructure across 1,600+ live retail stores, processing tens of billions of real-world events every day. We’re hiring a Site Reliability Engineer to own the reliability of that system end to end — leading incident response, running day-to-day NOC operations, and building the observability foundation that lets us catch issues before they hit a store floor. You’ll be the steady hand during a live incident, and the engineer making sure there are fewer of them to begin with.

Responsibilities:

• Own the incident management lifecycle end to end: detection, triage, escalation, communication, resolution, and postmortem for production incidents. • Act as Incident Commander for high severity incidents, coordinating across engineering, support, and leadership until resolution. • Run day-to-day NOC (Network Operations Center) operations, including 24/7 shift coverage, escalation matrices, and shift handover protocols. • Coach and mentor NOC analysts on triage discipline and escalation judgment, and own NOC KPIs like response time and escalation accuracy. • Design and maintain observability pipelines across metrics, logs, and traces, and define SLIs/SLOs with engineering and product. • Build dashboards and alert that surface true signal from our sensor and platform data, cutting down on noise and alert fatigue. • Facilitate blameless postmortems and root cause analysis, and track corrective actions through to closure. • Maintain on-call rotations, runbooks, and escalation policies, and report on MTTA/MTTR/MTBF trends to leadership.
