The Defense Security Cooperation Agency (DSCA) Program, Analytical, Technical, and Enterprise (PATAE) contract seeks to support program management, monitoring & evaluation, policy and international affairs, strategic communications, and analytics/R&D, ensuring timely, accurate, and policy‑compliant deliverables. Core capabilities include strategic planning and integration, program design and management, performance improvement, data and resource management, quality control/assurance, and subject-matter expertise in security cooperation operations.

The anticipated period of performance is five (5) years with an optional 6-month extension of services.

The Systems/Project Engineer provides technical leadership and hands‑on engineering support for complex developmental and operational weapon system programs, system elements, and interfacing components. Responsible for systems engineering tasks across the lifecycle—requirements analysis, design, integration, verification/validation, and support to test & evaluation—this role works independently or leads teams to resolve technical issues, apply engineering best practices (including Agile where applicable), and ensure successful transition of capabilities into operations.

Essential Job Functions:

• Lead and execute systems engineering activities: requirements derivation, functional analysis, architecture development, interface definition, and system integration.
• Develop technical approaches, engineering work products, system specifications, and integration plans to support task‑order objectives.
• Support and/or lead test & evaluation planning and execution; develop test plans, coordinate T&E events, analyze results, and produce test reports and recommendations.
• Provide daily supervision and technical direction to engineering teams or work groups, assigning tasks, reviewing work, and ensuring quality of deliverables.
• Apply systems engineering processes and tools (MBSE, configuration management, trade studies, modeling & simulation) to inform design decisions and risk mitigation.
• Integrate cybersecurity, information assurance, and interoperability requirements into system design and documentation in coordination with Technical Security Specialists.
• Manage technical interfaces with stakeholders (Government CORs, OEMs, integrators) to resolve engineering issues and coordinate deliverable acceptance.
• Support agile program execution where applicable: sprint planning, backlog management, iterative development, and continuous integration/verification.
• Produce technical reports, briefings, system documentation (SSP, ICDs, CONOPS), and maintain records in Government repositories.

Required Qualifications:

• Bachelor's degree in systems engineering, electrical/mechanical/computer engineering, computer science, or related technical discipline. Master's Degree in relevant field.
• Minimum seven (7) years of experience in systems engineering for complex defense systems, including requirements, integration, and T&E support.
• Demonstrated experience leading engineering teams or work groups and providing daily technical supervision.
• Hands‑on experience with systems engineering tools and methods (modeling & simulation, MBSE, CM, trade studies) and producing engineering…
