Senior Software Engineer: Fleet Operations and Test

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 a Senior Software Engineer 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.
