RF/Radar Hardware Engineer to $6000

We're building a contactless inmate monitoring system for correctional facilities using millimeter-wave radar sensors. The system needs to track a person's position and stream real-time vitals (heart rate, respiratory rate) from within a small concrete cell.

What you'd be doing:

Designing and deploying a multi-sensor radar setup in a 3×3m cell environment with heavy concrete and steel surfaces. 

We're looking for someone with:

• Strong RF engineering fundamentals — antenna design, propagation modeling, interference mitigation
• Hands-on experience with FMCW or CW radar modules (60 GHz preferred)
• Ability to design synchronization/multiplexing schemes for co-located radar sensors
• Familiarity with multipath-heavy environments (concrete, steel)
• Embedded systems skills for sensor integration and real-time data streaming
• Signal processing experience (range estimation, triangulation, vital-sign extraction from radar returns)

Nice to have:

• Experience with point-cloud or micro-Doppler processing for human activity recognition
• Background in sensor fusion or RTLS (real-time location systems)
• Familiarity with the Seeed/60 GHz sensor ecosystem
