  • An active U.S. Secret security clearance is required.

Responsibilities

  • Lead the definition, decomposition, allocation, management, verification, and validation of hardware and software requirements for complex technical products and systems.
  • Provide technical leadership for large, cross-functional systems-engineering initiatives across the lifecycle, including concept, design, fabrication, test, installation, operation, maintenance, and disposal.
  • Analyze program objectives, concepts of operation, equipment, functions, interfaces, and operational needs to establish an integrated technical approach for complex systems.
  • Translate customer and product requirements into system solutions that balance technical performance, schedule, cost, risk, supportability, and effectiveness constraints.
  • Direct functional and timeline analysis, trade studies, requirements allocation, interface-definition work, and resolution of complex technical issues across multiple disciplines.
  • Establish and maintain an integrated requirements baseline; lead definition, flow-down, traceability, verification planning, and model-based systems-engineering work for complex electronic systems.
  • Lead development and technical integration of systems-engineering work products, including system specifications, derived and linked requirements, interface definitions, system diagrams, analyses, trade studies, and detailed designs.
  • Provide technical leadership for program design reviews and influence internal and external stakeholders on systems-engineering practices, approaches, and technical decisions.
  • Coach and guide engineers across the organization and drive significant improvements to systems-engineering processes, methods, or products.

Desired Qualifications

  • Demonstrated experience leading complex systems-engineering work and government program acquisition-lifecycle activities across multiple engineering disciplines.
  • Experience leading application of a recognized systems-engineering process, such as MIL-STD-499, EIA-632, IEEE 1220, or ISO/IEC/IEEE 15288.
  • Experience leading requirements-management and model-based systems-engineering activities using tools appropriate to the work, such as DOORS and MBSE toolsets.
  • Advanced knowledge of model-based systems-engineering languages, including UML, SysML, and UPDM.
  • Experience with frameworks including DoDAF, UAF, and Magic Grid.
  • Experience applying methodologies including OOSEM, Harmony-SE, RUP-SE, or OPM to complex, cross-functional technical work.
