Your territory

As part of our Hardware team, you will:

• Analyze and optimize RF performance for our next-generation pet trackers with focus on antenna efficiency, power consumption, and wireless reliability through antenna matching, tuning, and integration activities

• Define RF requirements and validation criteria during product development for LTE, GNSS, Wi-Fi, and BLE technologies

• Perform comprehensive RF validation and characterization, designing and executing RF performance test plans with detailed measurement reports and pass/fail verdicts

• Conduct passive and active RF measurements including TRP/TIS, conducted and radiated measurements, sensitivity, coexistence, and OTA testing

• Perform RF debugging at system and PCB level including interference, desense, harmonics, spurious emissions, and EMC-related issues

• Review RF layouts and provide design recommendations to hardware teams for optimal RF performance

• Work closely with hardware and firmware teams on radio architecture and wireless subsystem integration

• Support certification activities including FCC, CE, IC, RCM, and EMC/EMI compliance, collaborating with external labs, antenna vendors, chipset vendors, and certification partners

• Develop and maintain automation scripts for RF instruments and validation workflows

• Support production RF testing activities, analyze production yield issues, and collaborate with manufacturing teams to ensure consistent wireless performance during mass production

• Bring in your fresh ideas to make Tractive better - you’ll never hear the phrase “...because that’s how we’ve always done things”

• Continuously grow personally and professionally, take ownership of areas that show your potential, and attend workshops which help you get to the next level
