Firmware Engineer

Location: Kitchener, Canada

Department: Hardware

Who You Are:

• Someone who thrives in ambiguity. Early-stage companies don’t hand you a spec and walk away. You’re comfortable defining problems as much as solving them, and you’ve learned to make good decisions with incomplete information.
• A systems thinker at the hardware-software boundary. You find satisfaction in making complex systems work reliably (and you know how to apply Gall’s Law to get there). When debugging an issue, you naturally consider how all the pieces connect and interact. You’re drawn to the intersection of hardware and software, where the abstractions are thinner and the consequences of your decisions are more tangible.
• An empathetic collaborator. You enjoy working with hardware engineers on bring-up, backend teams on device-to-server communication, field ops on diagnostics, customer support on real-world issues, and more. You communicate clearly across these boundaries, and you remember that at the end of the day we all succeed or fail together.

What We Need:

• End-to-end ownership of device firmware. Our Jetson Hub and Jetson Thermostat control heat pumps, water heaters, EV chargers, and other home comfort & energy devices, and the magic is in their software. These aren’t disposable gadgets: our devices need to run reliably for 10+ years in homes across the continent.
• Embedded systems depth. Production C or C++ on microcontrollers. Experience with communication protocols (Modbus, BLE, Wifi, LoRa), memory management, and real-time constraints. Comfort debugging hardware-software interactions.
• Engineering rigour. Tests, code review, and CI/CD are table stakes–practices which are often treated as optional in firmware. Not at Jetson.
• Designing for resiliency. Think through failure modes before writing code, but assume the device will encounter unanticipated conditions anyway. Design for diagnostics, graceful degradation, and self-healing recovery paths: we should never have to roll a truck to fix a software bug.
• Comfort with on-call responsibility. Our customers rely on our systems to heat & cool their homes. When production issues arise, we need engineers who can quickly diagnose, resolve, and ensure they don’t happen again.

How You Will Grow:

• Develop expertise in high-reliability, long-lived systems. Most IoT devices are toys, and most high-reliability software ships once and never changes. Not at Jetson: we keep homes comfortable and safe while pushing new features. You’ll learn to build resilient software that survives a decade in the field and evolves along the way.
• See the full picture, and influence it. Firmware at Jetson touches hardware, cloud infrastructure, energy markets, end customers, and more. You’ll gain context that’s rare for firmware engineers, with the opportunity to expand into adjacent areas if you’re interested.
• Shape how we build. We’re a small team building our practices as we go. You’ll help shape our firmware architecture, tooling, and standards, including how we use AI to move faster than ever.

About the Company

About Jetson:

Jetson is on a mission to accelerate the transition of 100 million homes across North America away from fossil fuels toward sustainable energy use. We believe in a future that is 100% electric and 100% better.

Homes are one of the largest sources of carbon emissions, yet adoption of solutions like heat pumps remains slow due to cost and complexity. Jetson is solving this by building the first fully vertically integrated home electrification company — making clean energy simple, transparent, and affordable.

We rely heavily on technology, automation, and data to scale this impact. At Jetson, we value people who are excellent at their craft, curious about new tools (including AI), and motivated to continuously improve how work gets done.
