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

The CMMC Compliance & IT Support Specialist leads Fathom Robotics’ day-to-day readiness for CMMC Level 2 and supports the systems we use to handle Controlled Unclassified Information (CUI) on Department of Defense programs. Most of the role is compliance work; the rest is hands-on IT support for our team.

This person works closely with the Chief Administrative Officer and our outside IT providers. The aim is a security program that holds up at assessment and fits the way our engineering, operations, and field staff work.

Meeting CMMC requirements is a condition of our DoD contract work.

LOCATION: Fort Worth, TX (Hybrid)

WORK TYPE: Part-Time, approximately 20 hours per week

CLEARANCE: US Person Required | SECRET Eligible (Minimum)

PROGRAM CONDITIONS

This is a part-time, hybrid position of approximately 20 hours per week based in Fort Worth, TX, scheduled around agreed core hours with some flexibility. On-site time is needed for hands-on equipment work and in-person coordination. Workload increases in the weeks leading up to a self-assessment or third-party assessment, and system maintenance may occasionally need to happen outside normal business hours to avoid disrupting program work. Limited travel to other Fathom Robotics sites may be required.
