What this job asks for AI summary
A senior-level embedded engineering role focused on taking wireless hardware products from initial concept through to high-volume manufacture. The work centers on writing production C code for real-time operating systems, architecting a custom sub-GHz wireless protocol, and building HIL/SIL test frameworks, while collaborating across electrical, mechanical, and industrial design disciplines. Best suited to someone with deep embedded software experience and a background in ultra-low-power wireless systems.
Senior level · 6+ years · Salt Lake City, UT · Full-time
“or” means any one of them counts — you don't need all of them.
We read this from the posting text with AI. Skim the description below before ruling yourself out.
Why we read it this way (8)
PassiveLogic is headquartered in Salt Lake City, UT; the posting describes an in-office role (in-office lunch perk, no remote language), so the CBSA is inferred from the company's known location.
The role sits at the intersection of embedded firmware (C, RTOS) and hardware-adjacent work (board bring-up, RF, schematic review). 15-1252 Software Developers is the best fit because the primary deliverable is production-grade embedded software; 15-1299 is noted as a runner-up given the strong hardware/systems engineering flavor.
TI-RTOS and Zephyr RTOS are listed together as a paired requirement in the 'You Must Have' section; they are treated as interchangeable alternatives (the role requires deep RTOS expertise, with either qualifying).
IEEE 802.15.4, BLE, and 900 MHz sub-GHz protocols appear under 'You should have' (secondary requirements section) as examples of ultra-low-power wireless protocol knowledge — listed as preferred. 900 MHz is a frequency band rather than a named protocol standard, so it is not emitted as a separate skill.
Altium (schematic capture/board layout) and RF design/compliance testing appear under 'You should have' — preferred, not hard gates.
AI-assisted testing systems are explicitly called a 'bonus' in the posting and are not emitted as a skill.
No compensation figures are provided; the posting states only 'competitive compensation' and equity.
Ignored 1 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): RF design.
