Senior Embedded Systems Engineer (Wireless Product Development)

About the role

PassiveLogic, a building automation platform, is looking for a Senior Embedded Systems Engineer to co-lead the development of its suite of wireless products from concept to manufacture. The engineer works closely with electrical, mechanical, industrial design and verification and validation teams to deliver robust, innovative solutions.

Key responsibilities

• Lead end-to-end development of ultra-low-power wireless devices, from architecture design to high-volume production.
• Write and optimize production-ready C code for embedded systems running TI-RTOS and Zephyr RTOS.
• Lead the architecture, implementation and refinement of a custom sub-GHz wireless protocol, evaluating technical trade-offs.
• Apply math and physics to power accounting and systems-of-systems optimization in resource-constrained environments.
• Design and implement HIL/SIL testing frameworks to validate robust, fail-safe code before V&V handoff.
• Use Git, Python, Bash and Linux to maintain clean, modular codebases and automate workflows.
• Perform hands-on board bring-up and system debugging to integrate hardware and software.

Required profile

• Degree in Electrical Engineering, Computer Engineering, Computer Science or a related field, or proven exceptional ability through experience.
• 6+ years in embedded software development with deep expertise in C and real-time operating systems (TI-RTOS, Zephyr RTOS).
• Track record of production-grade code with rigorous HIL/SIL testing.
• Strong communication, organization, collaboration and adaptability in a fast-paced startup environment.
• Bonus: experience with AI-assisted testing systems, interfacing with overseas vendors, mentoring junior engineers or leading cross-functional teams.

Required skills

• C programming and real-time OSes (TI-RTOS, Zephyr RTOS)
• Git, Python, Bash and Linux
• Altium for schematic capture and board layout
• Power budgeting and system modeling with spreadsheets
• Ultra-low-power wireless protocols (IEEE 802.15.4, BLE, 900 MHz) and RF design and compliance testing

What we offer

• Competitive compensation and a generous equity package
• Medical, dental and vision coverage, disability and life insurance options
• Flexible paid time off and team-building events
• Free catered lunch Monday through Friday, free National Parks pass, free ski pass and free ClassPass access
