• Systems engineering or program management certifications such as CSEP, ESEP, PMI / PMP.
• An active DoD secret security clearance or higher.

Responsibilities

• Provide engineering analysis and SE&I leadership for secure software applications supporting DoD mission planning and operations, with emphasis on integration oversight rather than feature factory development.
• Serve as the Government’s technical integrator across PTS G software elements other Space Force / DoD product teams, ensuring interoperability, data flow, message correctness, and operational alignment.
• Lead Government coordination with prime contractors and stakeholders to define mission use cases, system constraints, and integration priorities within governed DoD environments.

• Operational constraints for IL environments and cross domain data movement
• Produce and maintain Government technical artifacts used for contractor direction and evaluation, such as:
• Interface Control Documents (ICDs)
• Interface Requirements Specifications (IRS)
• Verification cross references and requirements traceability
• Test objectives, evaluation criteria, and acceptance measures (software integration focused)
• Plan and oversee software integration into restricted DoD operating environments, including air gapped and classified deployments, addressing sustainment constraints, network limitations, and accreditation realities
• Coordinate software deployment and integration activities with Government teams and primes using DoD aligned DevSecOps pipelines, including automated testing, security scanning, artifact management, and compliant delivery processes
• Ensure end to end integration supports mission workflows requiring cross domain data transport (when applicable), and that interfaces are testable and operationally supportable
• Define and lead software integration verification strategy: integration test approach, exit criteria, defect triage patterns, and readiness recommendations for Government decisions
• Drive continuous improvement via architecture and tooling recommendations to improve integration reliability, repeatability, and sustainment readiness
• Develop and present decision packages, technical recommendations, and risk assessments to customers at multiple levels; facilitate technical interchange with primes and Government teams
• Mentor engineers on secure integration patterns, interface discipline, verification rigor, and defense software engineering best practices
