🏢 About Fuse Energy

Fuse Energy is a renewable energy startup with $210M in funding from top-tier investors, aiming to deliver a terawatt of renewable energy fast. They combine first-principles thinking with cutting-edge technology to build a fully integrated energy company, including the decentralized Energy Network of smart devices. This is a unique opportunity to work on impactful hardware that balances the grid and supports AI data centers.

About This Role

As an Embedded Software Engineer, you will design, build, and scale the connected hardware powering the Energy Network. You'll work on embedded systems, networking, device security, and fleet connectivity from prototype to deployment, contributing to resilient connectivity and robust telemetry. Your work will directly impact grid stability and the renewable energy transition.

💡 A Day in the Life

A typical day might start with a stand-up to discuss progress on firmware features for the Energy Network, followed by coding in C/C++ for secure connectivity and telemetry. You might debug a device issue using logic analyzers, then collaborate with hardware engineers on prototype testing. Afternoons could involve reviewing OTA update strategies or writing documentation for fleet management.
