Senior Software Engineer

ABOUT FATHOM ROBOTICS

Fathom Robotics provides operations, maintenance, training, and applied engineering services for uncrewed maritime systems supporting U.S. Government and commercial defense programs. We have multiple active projects across a variety of government and commercial clients and are actively fielding systems in operational environments.

ROLE OVERVIEW

Fathom Robotics is hiring a Senior Software Engineer to develop software that directly supports a government program. The work is software development first: Linux-based services and tools, network and data systems, embedded and edge platforms, and the test automation that keeps them reliable.

You will work as a Fathom contractor alongside government and industry engineers, and own your work from design through delivery. This role suits an engineer who has shipped production software for government users and is comfortable owning the result.

Government users depend on this software working the first time it is fielded.
