Build embedded software that connects directly to the physical world—and help shape the next generation of an established embedded platform for an established 20-year-old company with a solid product suite, a great culture and a cleaner future.

Our client is a profitable, privately held technology company building hardware and software that help customers understand and improve energy use. With an established global customer base and a self-funded business, the company offers financial stability, meaningful technical challenges, and a sustainable pace of work.

They’re looking for a Senior Embedded Software Engineer who enjoys working close to the hardware, solving complex systems problems, and making thoughtful architectural decisions. This is a hands-on individual contributor role with significant ownership and room to deepen your technical impact without moving into management.

The Opportunity

You’ll develop firmware and low-level software for products used in real-world environments, supporting an established installed base while helping build what comes next.

A major focus will be evolving the software architecture, maintaining core C firmware, and helping lead a transition toward Rust. You’ll work closely with experienced technical leadership, hardware engineers, and product teams, contributing from early design and board bring-up through production and ongoing support.

Your judgment will matter here. Our client values engineers who ask thoughtful questions, challenge assumptions constructively, and address underlying problems with durable solutions.

What You’ll Do

• Develop and maintain embedded Linux components, including device drivers, kernel modules, and board support packages.
