• Bachelor's degree in Computer Science, Engineering, or a related field with 4–8 years of relevant experience, or an equivalent combination of education and experience.
• Demonstrated experience with full lifecycle systems engineering, development, integration, testing, and implementation activities.
• Strong hands-on experience configuring, administering, and troubleshooting VMware and ESXi virtualization environments.
• Demonstrated experience with hardware and software configuration of physical systems, including network configuration, cabling, and integration of physical devices.
• Experience developing and maintaining DoDAF architecture frameworks to support systems engineering design and implementation, including proficiency with Microsoft Visio.
• Demonstrated experience performing advanced Tier III-level troubleshooting, root cause analysis, and resolution of complex technical issues within operational environments.
• Experience developing, modifying, or maintaining automation scripts using technologies such as XML, Python, Bash, PowerShell, Java, or C++.
• Strong working knowledge of system development processes, databases, operating systems, and enterprise IT infrastructure concepts.
• Hands-on Linux command-line experience, with certification such as CompTIA Linux+ or Red Hat certification, and understanding of virtual machine architecture.
• Experience implementing and maintaining DISA STIGs and supporting security compliance within DoD environments.
• Must possess DoD 8140 (formerly 8570) IAT Level II certification (e.g., Security+) prior to start date and maintain certification.
• Demonstrated ability to independently analyze technical requirements, troubleshoot complex systems, and implement effective engineering solutions with minimal oversight.
• Strong analytical, organizational, and communication skills, with the ability to collaborate effectively across technical teams and mission stakeholders.
• Ability to manage multiple technical assignments, adapt to changing priorities, and consistently deliver high-quality work in a dynamic operational environment.
• Willingness to travel CONUS and OCONUS up to 10% of the time.

Preferred Qualifications

• Active TS clearance.
• Familiarity with containerization technologies, including Docker and OpenShift.
• Cisco Certified Network Associate (CCNA) certification.
• Experience supporting end-to-end cross domain systems development, integration, and deployment efforts.
• Experience working within DISA or other DoD enterprise environments.
• Experience with infrastructure automation and configuration management tools.
• Familiarity with engineering best practices such as Raise the Bar Version 5.
