Device Engineer II
About The Position
A rapidly expanding, entrepreneurial technology company, Alarm.com, is seeking an ambitious and talented RF/EMC Engineer. Very few small companies innovate and develop across such a broad range of technologies as Alarm.com. 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.
Requirements
- Bachelor of Science degree in Electrical Engineering or a similar technical discipline, with a background in RF and/or EMC.
- 2-3 years of hands-on experience performing RF performance and/or EMC testing and interpreting results against pass/fail criteria.
- Familiarity with different wireless communication protocols (cellular, WiFi, Bluetooth, sub-GHz).
- 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.
Nice To Haves
- 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.
- Master of Science degree in Electrical Engineering.
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.
Benefits
