About the Job

Requirements

  • A bachelor's degree in Electrical Engineering, Physics, Mathematics, Computer Science, or another relevant STEM field, plus at least 15 years of relevant experience; alternatively, a graduate degree plus at least 13 years of related experience, or 19 years of related experience in lieu of a degree.
  • Experience with project engineering best practices, capture and proposal execution, early lifecycle development, and program execution.
  • An active TS/SCI security clearance is required.

Responsibilities

  • Own the integrated technical baseline across capture, proposal, and early development transition activities for the program.
  • Lead and integrate cross-functional teams to define architecture, requirements, design concepts, technical discriminators, and executable plans aligned to customer mission needs.
  • Serve as the primary technical decision-maker for the pursuit baseline and communicate technical positions, assumptions, risks, and opportunities to leadership, customers, and teammates.
  • Lead concept development, architecture trades, requirements definition, model-based systems engineering and modeling, design analysis, and verification planning.
  • Apply knowledge of Department of Defense missions, especially space systems, to shape competitive, affordable, and executable mission solutions.
  • Own technical review content and proposal artifacts, including technical baseline packages, proposal cost estimates, technical volume inputs, basis of estimates, should-cost or design-to-cost activities, and customer-facing technical material.
  • Provide continuity from pursuit into program start-up by helping establish engineering strategy, technical plans, priorities, and resource alignment for executable development and later program success.
  • Provide mentorship, guidance, and leadership to other engineers and serve as a technical voice of the customer for the pursuit.
  • Establish and actively manage technical risks and opportunities, including cost-influencing technical decisions, mitigation strategies, and corrective actions for engineering issues.
  • Partner with Independent Review Teams and key stakeholders to improve pursuit readiness, proposal quality, and transition readiness into development.
  • Support holistic engineering performance by promoting cross-functional integration and adherence to applicable quality, safety, regulatory, and organizational process expectations as the program matures.
  • Partner with engineering disciplines, operations, supply chain, business development, finance, program management, security, and quality to develop the integrated technical baseline and support transition into development and later execution.
  • Prepare technical baseline packages, proposal cost estimates, proposal technical volume inputs, trade studies, design-to-cost planning, reuse strategy, and customer-facing technical material.
  • Help drive engineering strategy aligned to program and business priorities, support engineering plans and resource alignment, and promote adherence to quality, safety, regulatory, and organizational processes.

Desired Qualifications

  • Experience in an engineering leadership role such as Lead Pursuit Engineer, Chief Engineer, Chief Systems Engineer, Integrated Product Team Lead, Project Engineer, Technical Director, or a similar role.
  • Experience leading capture, proposal, architecture maturation, technical baseline development, or early lifecycle execution for defense or space systems programs.
  • Experience presenting to program leadership and external customers for technical reviews, pursuit gate reviews, technical negotiations, trade studies, requirements discussions, and data analysis.
  • Experience with design-to-cost, reuse strategy, model-based systems engineering, modeling, engineering planning, cross-functional resource coordination, or other advanced engineering practices.
