Senior Ground Systems Engineer

Overview

Modern Technology Solutions, Inc. (MTSI) is seeking a Sr Ground System Engineer with deep expertise in ACAT-like classified space control ground and command-and-control (C2) systems. This position directly supports a U.S. Space Force (USSF) program office responsible for developing, integrating, testing, and transitioning advanced ground architectures that enable responsive, resilient, and secure space control mission capabilities. Work will be performed in a secure government environment supporting highly sensitive programs across space, ground, and mission management domains.

Responsibilities

As a Sr Ground System Engineer, you will provide senior-level technical guidance on ground system architecture development, requirements analysis, interface design, information assurance, and integration activities for highly classified space control programs. You will support the government in evaluating system maturation, assessing engineering risks, and ensuring alignment across space, ground, and C2 segments. You will routinely brief senior government leadership, coordinate across multi-disciplinary engineering teams, and contribute to the development of acquisition and technical baseline documentation.

Roles And Responsibilities

• Serve as the technical expert on ACAT-like space control ground and C2 systems, including architecture development, system design, and integration activities.
• Develop, review, and refine DoDAF architecture views, interface diagrams, and end-to-end ground segment architectures supporting space control mission needs.
• Lead the development, evaluation, and documentation of the program’s Information Support Plans (ISPs) and related architectural products.
• Provide expert guidance on system requirements, performance modeling, and ground segment functional analysis to ensure alignment with program objectives.
• Evaluate system engineering artifacts from contractors, including requirements specifications, design reviews, ICDs, verification plans, and test documentation.
• Conduct trade studies assessing architecture alternatives, technology maturity, interoperability, and sustainment considerations for mission ground systems.
• Provide highly knowledgeable insight into DoD Information Assurance (IA) and cybersecurity design, testing, certification, and accreditation requirements.
• Support government decision-making by identifying impacts to cost, schedule, and system performance across ground system development and integration efforts.
• Coordinate with operations, security, test, software, network, and mission management teams to ensure technical consistency across all ground and C2 segments.
• Develop briefings, technical analyses, and decision-quality products for senior acquisition, engineering, and operational leadership.
• Represent the program office at government, military, contractor, and FFRDC technical meetings regarding ground and C2 capabilities.
  
  

Qualifications

• Expert-level knowledge of ACAT-like, highly classified ground and C2 systems supporting space control missions.
• Demonstrated experience developing and documenting DoDAF architecture views and program-level Information Support Plans.
• Deep knowledge of DoD Information Assurance, to include secure architecture design, cyber assessment, testing, certification, and accreditation.
• Ability to evaluate system-level architecture tradeoffs, identify technical risks, and support strategic engineering decision-making.
• Experience supporting DoD or Intelligence Community program offices within SAPF/SCIF environments.
• Strong written and verbal communication skills, capable of clearly presenting technical findings to senior government officials.
  
  

Desired Requirements

• Prior experience as a SETA, advisor, or lead systems engineer supporting highly classified ground system development programs.
• Experience with ACAT I/II-like programs and advanced technology development efforts.
• Familiarity with DoD acquisition documentation, SOW/PWS development, risk management processes, and engineering technical review frameworks.
• Understanding of integrated space-ground-cyber architecture development and mission assurance principles.
  
  

Education Requirements

• MA/MS degree required.
• Tradeoff: A Bachelor’s degree is acceptable with 12 years of directly relevant experience in similar roles or programs.
• The Materiel Leader may waive the MA/MS requirement based on experience and mission needs.
• Degree should be in engineering, computer science, physics, or a related technical discipline from an accredited institution.
  
  

Clearance Requirements

• Active TS/SCI eligibility required; must be willing to work in SAP environments.
• Must maintain TS/SCI eligibility and be willing to undergo a Counter-Intelligence polygraph.
• U.S. Citizenship is required.
  
  

Location/Travel Requirements

• Full-time on-site support within secure government facilities (SAPF/SCIF).
• Travel approximately 15–20% within CONUS; some OCONUS travel may be required depending on mission needs.
