Linux Systems Engineer

Job Title: Linux Systems Engineer (Mid-Level)
Location: Middle River, MD (Hybrid)
Employment Type: Full-Time (Hybrid). 3 days per week on-site, plus on-site presence for projects, experimentation, and testing events. Includes occasional outdoor work in varying terrain and weather, and travel 2–3 times per year for up to two weeks.

Salary: $110K – $135K

Position Overview:
MCFA is partnering with a defense research organization and leading their search for a Robotics Engineer to support intelligent robotics research. You’ll focus on software and hardware integration for proof-of-concept demonstrations and performance evaluation of autonomous behaviors on individual robots and teams of ground and aerial platforms. 

Key Responsibilities:

• Administer Linux servers, services, and research systems supporting the ROS Enclave, VPG computing environment, virtual test range, and lab and field platforms (Ubuntu and/or RHEL derivatives)


• Build, configure, patch, monitor, and troubleshoot Linux hosts used for simulation, data handling, robotics integration, and LVC / hardware-in-the-loop (HWIL) experimentation


• Manage researcher and partner access to prototype environments, including accounts, permissions, storage, and secure data-management processes


• Partner with the Network Engineer and ARL researchers to integrate Linux systems with wired, wireless, tactical, and campus test networks


• Support HPC access, data movement, and software transition into the LVC toolkit, including command-line transfer tools, live analytics, and modeling workflows


• Help define the computing and HPC capabilities for VPG integration through requirements gathering, trade-space evaluation, and architecture design. The systems aren’t predetermined, so you’ll help shape them.


• Develop and maintain SOPs, operating policies, user guides, system diagrams, and usage/performance reports


• Provide onsite and remote support for architecture reviews, integration events, demonstrations, and experimentation
  

Qualifications:

• Bachelor’s degree in computer information systems, Systems Administration, Computer Science, or a related technical field


• 3–5 years of Linux systems administration or systems engineering experience


• U.S. citizenship and an active U.S. SECRET clearance, or the ability to obtain one


• DoD 8140-aligned certification (minimum CompTIA Security+ CE or equivalent; legacy DoD 8570 IAT II acceptable), or the ability to obtain one within 3 months of start


• Hands-on Linux administration (Ubuntu and/or RHEL): package, user, and service management, storage, shell scripting, and troubleshooting


• Experience deploying software with Docker/Podman containers and orchestrating with Kubernetes


• Familiarity with configuration management and automation tools (Ansible, Puppet, Chef)


• Experience supporting HPC access or high-end simulation / AI development systems


• Working knowledge of networked Linux systems (TCP/IP, VLANs, VPN/remote access, DNS, firewalls) and troubleshooting tools (SSH, rsync, journalctl, tcpdump, Wireshark)


• Working understanding of system security standards (STIGs, CIS benchmarks, patch and configuration management)

Bonus Points:

• Experience with ROS / ROS 2 environments or Linux hosts used with robotic platforms


• Experience supporting autonomous vehicles, robotic platforms, or field experimentation environments


• Linux+ or RHCSA certification


• Network administration experience


• Strong communication, documentation, and customer-service skills

Total Rewards:

• Competitive base salary


• Hybrid schedule


• Support for required professional certifications


• Hands-on work shaping HPC and simulation architecture at one of the nation’s premier DoD research sites
