How to Apply for Sr Principal Software Systems Engineer

at Enovix

🏢 About Enovix

Enovix is pioneering next-generation lithium-ion battery technology with a unique 3D silicon architecture that delivers higher energy density and improved safety. As a company focused on sustainable energy storage, you'll work on cutting-edge technology that directly impacts the clean energy transition. The remote-first culture offers flexibility while working on impactful projects.

About This Role

This role involves developing software for battery management and control systems, including GUI design and algorithm modeling for high-energy-density power applications. You'll bridge the gap between complex system data and user-friendly interfaces, directly contributing to the performance and safety of next-gen batteries. Your work will support both product development and manufacturing systems.

💡 A Day in the Life

A typical day might involve collaborating with hardware engineers to define software requirements for a new battery management system, then writing C++ code for a GUI that visualizes real-time battery data. You'd also model control algorithms in Python, simulate their performance, and later test them on embedded hardware in the lab.
