About The Position

Embedded Systems and Firmware @ Torus
We’re building energy storage and management solutions that help:
Homeowners become their own renewable energy provider—saving money and reducing carbon emissions.
Commercial and industrial businesses reduce their operating costs while increasing reliability.
Grid operators keep the electricity grid stable and cost efficient.

Torus is hiring a Staff Embedded Systems Engineer to be a senior level individual contributor on our firmware team, working in close partnership with our Firmware Architect. This is a hands-on role where you'll translate architectural direction into well-engineered, production-grade firmware, raise the technical bar across the team, and take deep ownership of the most complex problems in our embedded stack—from serial protocol integrations to fleet-scale deployment and field diagnostics.
Our Tech Stack
Our firmware application layer is Python on Embedded Linux (Yocto)—not C, not C++. This was a deliberate architectural choice: Python gives us speed-to-market, flexibility to respond to changing grid program requirements, and a clean separation between hardware and application logic. Our comms are primarily RS-485, so Python runtime overhead is seldom the limiting factor.

If you've been writing Python to control hardware over serial protocols—in energy, robotics, industrial IoT, or test & measurement—you'll feel immediately at home here. If you've spent your career in C/C++ and are looking for that, this probably isn't the right fit.

Each Torus device generates over a million data points per day and integrates with our cloud platform via MQTT/AWS IoT. Our systems also participate in Virtual Power Plant (VPP) programs, responding to real-time dispatch signals from utilities—which means our firmware decisions have direct, measurable impact on grid operations.

Requirements

• BS in Electrical Engineering, Computer Science, Embedded Systems, or equivalent practical experience.
• 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.
• Proven track record leading or mentoring engineers on technical projects.

Nice To Haves

• Experience with IoT device management at scale (fleet OTA, remote diagnostics).
• Familiarity with AWS IoT, MQTT, or data telemetry pipelines.
• Exposure to energy storage systems, inverters, or grid-connected hardware.
• Knowledge of VPP programs, demand response, or utility interconnection standards (IEEE 1547, UL 1741).
• Experience with containerized embedded deployments (Docker/Balena on Linux targets).
• CI/CD practices in embedded or hardware-adjacent environments.

Responsibilities

• Supporting and mentoring a small team of firmware engineers—ensuring technical direction matches the architectural intent, reviewing designs, and building a culture of responsiveness and collaboration.
• Developing firmware features across our 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.

Benefits

• Employee Rewards Package including Equity
• 401(k) Retirement Savings Plan
• Health Benefits Package: Choice between traditional PPO or HSA eligible medical plans; Dental insurance; and Vision insurance
• Human-centered Paid Time Off including Unlimited Discretionary PTO; 10-days paid company holidays; Waiting period-free 100% paid parental leave
• Torus paid Life and AD&D Insurance with option to purchase additional coverage
• Voluntary Short- and Long-Term Disability Insurance
• Peer Recognition Program
