The RF/EMC Engineer position is ideal for candidates who want to work hands-on with technologies such as cellular networks (LTE, Cat-M, NB-IoT, RedCap, eRedCap), WiFi, Bluetooth, LoRa and mesh/star sub-GHz networks. Opportunities include testing, validating, and certifying the performance of cutting-edge security devices, innovative sensing applications, and life-safety devices. This is a lab-focused role for an engineer who enjoys owning test execution end-to-end — from bench measurement through external certification — while contributing to the RF and EMC quality of in-house hardware designs.

RESPONSIBILITIES

• Independently plan and perform RF performance and EMC pre-compliance testing in accordance with product specifications and applicable regulatory requirements (FCC, ISED, CE/RED).


• Complete RF performance measurements (e.g., TRP/TIS, conducted power/spectrum, radiated/conducted emissions) to guarantee high performance across radios.


• Evaluate, troubleshoot, and help optimize the RF performance and EMC compliance of multi-radio, in-house designed hardware.


• Own the certification workflow: prepare test samples, develop test instructions, and witness/support testing at external certification labs.


• Clearly document and analyze test results, and communicate findings to design and program teams.


• Optimize and expand our testing capabilities using AI tools and other SW tools.


• Operate independently while working with senior management to stay fully aligned with company priorities, goals, and strategies.


• Other duties as assigned.

• Experience troubleshooting RF performance issues and EMC compliance failures.


• Ability to read and understand electronic schematics.


• Experience using electrical and RF lab equipment, such as: oscilloscope, DC power analyzer, spectrum analyzer, vector network analyzer, signal generator, and cellular communication tester.


• Rigorous attention to detail with focus on robustness, scalability, and quality of products.


• Self-motivation and the discipline to thoroughly test and vet wireless devices.


• Ability to work on multiple projects simultaneously in a fast-paced environment.

BONUS POINTS FOR

• Familiarity with regulatory certification processes and standards (FCC, ISED, CE/RED) and preparing devices for external certification.


• Skilled in antenna impedance matching, characterization, and optimization.


• Experience scripting/automating lab tests using Python or another scripting language.


• HW engineering design experience including schematic capture, layout design, and hardware bring-up.


• Experience conducting simulation using Ansys SIwave and HFSS software.
