Responsibilities include Creo CAD and drawing development, GD&T, interface closure, integration issue resolution, design updates, verification planning, design reviews, configuration boards, and supplier coordination. The role supports flight hardware development and requires collaboration with manufacturing, AIT, procurement, and inspection teams.

Own detailed CAD design and configuration quality for spacecraft flight hardware, including structures, mechanisms, brackets, harness accommodations, and payload mounts. Build and maintain Creo assemblies, manage packaging and clearances, release GD&T-compliant drawings, and maintain BOM accuracy in Windchill. Partner with manufacturing and assembly, integration, and test teams to ensure hardware is producible and testable. Support spacecraft integration, rework disposition, design reviews, and configuration control while mentoring designers and establishing CAD and release standards.

Develop and lead persuasive federal proposal content for national security, civil, and commercial space pursuits. Create win themes, strategic messaging, storyboards, executive summaries, technical narratives, and content plans. Translate complex aerospace and technical concepts into customer-focused messaging, collaborate with capture managers and subject matter experts, support proposal reviews, mentor writers, and maintain content libraries and best practices across multiple concurrent pursuits.

Plans, coordinates, and executes spacecraft, subsystem, software, hardware, and integrated system testing. Develops test procedures and displays, verifies readiness, monitors telemetry and system health, manages configuration control, resolves anomalies, documents results, and supports environmental qualification, mission simulations, launch readiness, and requirements verification. The role coordinates multidisciplinary teams during time-sensitive test operations while maintaining safety, procedural discipline, hardware integrity, and mission assurance.

Own the end-to-end spacecraft guidance, navigation, and control subsystem across multiple programs. Lead GNC architecture, attitude and orbit control design, estimation, simulations, verification, flight software integration, telemetry analysis, anomaly resolution, and mission operations support. Define control laws for high-Delta-V maneuvering, precision pointing, station-keeping, and proximity operations. Mentor engineers and serve as the technical authority in system reviews and spacecraft development.

Design, develop, and operate ground support equipment and vacuum test infrastructure for electric propulsion systems. Responsibilities include configuring vacuum chambers, writing procedures and safety documentation, executing environmental test campaigns, collecting data, troubleshooting vacuum and hardware issues, maintaining pumps and instrumentation, and supporting test-system requirements. The engineer collaborates with propulsion, mechanical, electrical, thermal, and integration teams while working hands-on with flight-grade hardware.
