Senior Software Engineer

Software Engineering · Seattle, Washington

First Mode is a carbon reduction company developing creative, clean energy solutions for heavy industry’s toughest problems.

We hope you’ll join us in building a brighter future for people and planet.

First Mode is seeking engineers to join our software team and contribute to the development of our clean energy technologies. Applicants from all industries are welcome, with particular emphasis in software development in complex, multidisciplinary systems.

You will help build the software that powers our clean energy product line, leveraging modern tools, techniques, and best practices to craft solutions to real-world problems. Our software projects span a wide spectrum from embedded systems to large-scale distributed computing, but usually involve interaction with a physical system. You will work alongside -- and learn from! -- engineers of mixed disciplines as you think outside the boundaries of your own code to make a major impact on the systems we design and implement.

A successful engineer in this role will thrive in an inventive environment and be excited by researching and teaching themselves new technologies and skills. You will be hands-on with hardware and learn about the clean energy space in the lab, in the field, and in building the software to operate our vehicle fleets.
