Software Systems Engineer

• Perform systems engineering for software-intensive systems, including requirements analysis, functional decomposition, interface definition, and architecture development.
• Elicit, document, and manage system and software requirements in collaboration with warfighters, mission stakeholders and development teams.
• Develop and maintain system architectures, data flows, and technical baseline documentation (e.g., ICDs, design descriptions, CONOPS).
• Support software integration troubleshooting and issue resolution across multiple components and environments.
• Participate in and/or lead technical reviews (SRR, PDR, CDR, TRR) and provide technical input to decision-makers.
• Work with software development teams using Agile and DevSecOps practices; support backlog refinement, sprint planning, and acceptance criteria definition.
• Define and support verification and validation (V&V) activities, including test planning, test case development, and requirements traceability.
• Collaborate with cybersecurity, infrastructure, and operations teams to ensure solutions meet performance, security, and availability requirements.
• Support risk management, issue tracking, and configuration management of system baselines.
• Prepare and deliver technical briefings, status reports, and engineering artifacts to both technical and non-technical audiences, including government customers.

• Active TS/SCI clearance is required at the time of hire.
• Bachelor s degree in Computer Science, Computer Engineering, Systems Engineering, or a related technical discipline;
• Additional years of relevant experience may be considered in lieu of a degree per contract guidelines.
• 5+ years of experience in systems engineering and/or software engineering on complex, software-intensive systems.
• Demonstrated experience with:
  • Requirements development, analysis, and management (e.g., DOORS, Jama, JIRA, or similar).
  • Development of system-level designs, architecture diagrams, and interface control documents.
  • Strong understanding of software development lifecycles (SDLC) and systems engineering processes (e.g., INCOSE, ISO, or DoD/IC standards).
  • Conducting or supporting **system integration and test** activities in lab or operational environments.
  • Excellent technical communication skills (written and verbal), including the ability to synthesize complex technical topics for diverse audiences.
  • Proven ability to work onsite in a classified environment, collaborating closely with customer and contractor teammates.

• Master s degree in a relevant technical field (CS, CE, SE, EE, etc.).
• Experience supporting DoD or Intelligence Community (IC) programs.
• Experience with:
  • Cloud environments** (AWS, Azure, or government cloud variants).
  • Microservices, containerization, and orchestration** (Docker, Kubernetes).
  • DevSecOps pipelines and CI/CD tools (GitLab, Jenkins, Nexus, SonarQube, etc.).
  • Model-Based Systems Engineering (MBSE) tools and approaches (Cameo, MagicDraw, SysML).
  • Familiarity with zero trust, cybersecurity controls (NIST 800-53, RMF), and secure software design principles.
  • Experience defining and maintaining Interface Control Documents (ICDs) and data models for distributed systems.
  • Relevant certifications (e.g., INCOSE CSEP, AWS/Azure certifications, SAFe, PMP, or security-related certs such as Security+ if applicable to contract).
