Job summary

Torus is hiring a Firmware Engineer to join our embedded systems team. The role centers on Python-based firmware on Embedded Linux (Yocto) for energy storage and grid-ready devices, with RS-485 communication and cloud integration via MQTT/AWS IoT. You will translate architecture into production code and collaborate with hardware, data, and software teams.

This is a remote U.S.-based position with occasional onsite work in Salt Lake City. Compensation ranges from $135,000 to $180,000 per year.

Qualifications

• BS in Electrical Engineering, Computer Science, Embedded Systems, or equivalent.
• 2-5+ years of hands-on experience developing commercial embedded software or firmware applications.
• Strong Python proficiency and real production experience running Python on Embedded Linux (Yocto or similar).
• Solid understanding of serial communication protocols—RS-485, Modbus, I²C, CAN, Ethernet.
• Experience with real-time embedded systems: multi-threading, inter-process communication, timing constraints.
• Ability to read schematics and PCB layouts to troubleshoot hardware integration issues.

Responsibilities

• Developing firmware features across energy storage product lines: telemetry, control loops, cloud connectivity, and hardware abstraction layers.
• Owning system integration —working closely with hardware, data, and software teams to ensure seamless interoperability across the full stack.
• Driving quality through design reviews, automated testing, and documentation. (We believe engineers own their own QA.)
• Debugging and optimizing real-time embedded applications and serial communication interfaces in the field and in the lab.
• Supporting scaling operations —deployment tooling, remote monitoring, and root-cause analysis of field issues across a growing fleet.
• Participate in on-call rotation for escalated technical issues.
