Compensation USD (period not stated)

is a rapidly expanding technology company developing innovative cloud and device solutions across a wide range of cutting-edge technologies that provide a unified, connected service to millions of residential and commercial properties in the US and abroad. We are looking for a talented and passionate RF/EMC engineer to join the Device Engineering team and help us define the future of the Internet-of-Things for residential and commercial properties by creating and integrating devices including security panels, networking gateways, and video cameras.

You will be working with a team of talented engineers across a diverse set of technological backgrounds to design devices, build and manufacture hardware, architect and implement software, and collaborate in an agile and fast-paced environment.

You will work on cellular (LTE, Cat-M, NB-IoT, Red Cap), Wi-Fi, Bluetooth, LoRa, and sub-GHz radios in security, sensing, and life-safety devices. About two-thirds of the role is RF performance and EMC testing and verification, done independently. The other third is design: matching antennas, reviewing RF and EMI-sensitive circuits, and turning test failures into design fixes, working with senior RF engineers who will grow you into simulation and RF circuit design.

Areas the team owns; prior exposure is a plus, not a prerequisite.

• RF performance testing, conducted and over-the-air: TRP/TIS, output power, spectrum, and receiver sensitivity.
• EMC pre-compliance testing and debugging: radiated and conducted emissions and immunity.
• Antenna matching, characterization, and placement in the product enclosure.
• RF front-end and EMI design reviews, and design fixes proven on the bench.
• Antenna and EMI simulation with Ansys HFSS and SIwave.
• Regulatory certification support (FCC, ISED, CE/RED) at external laboratories.
• Test automation for repeatable measurements.

• Independently plan and perform RF performance and EMC pre-compliance testing on multi-radio hardware against product specifications and regulatory requirements (FCC, ISED, CE/RED).
• Document and analyze results; state the impact on product performance and communicate findings to design and program teams.
• Design and tune antenna matching networks, single- and multi-band, and characterize antennas in the product enclosure.
• Participate in schematic and layout reviews of RF front ends, antennas, and EMI-sensitive circuits.
• Troubleshoot RF performance and EMC failures, propose design changes, and verify them on the bench.
• Contribute RF circuit blocks and run antenna and EMI simulations with senior engineers.
• Support certification testing: prepare samples, write test instructions, and witness testing at external laboratories.
• Automate repeated measurements to increase test throughput and reliability, using AI and software tools.
• Communicate effectively and collaborate with others to ensure the timely delivery of projects.
• Other duties as assigned.

• Bachelor's degree in Electrical Engineering or a related technical field, with coursework or experience in RF, microwave, or EMC.
• 2+ years of hands‑on RF or EMC testing; graduate research and co‑ops count.
• Works independently: scopes their own work, follows through, and communicates progress and blockers early.
• RF and EMC test results analysis and able to explain results to non-RF team members.
• Hands‑on use of spectrum analyzers, vector network analyzers, signal generators, oscilloscopes, DC power analyzers, and cellular communication testers.
• Designs single-band impedance matching networks from VNA measurements using Smith chart fundamentals.
• Understands the types and sources of EMI and common…
