Candidate must have strong proficiency in requirements definition and control, spacecraft bus system experience, launch vehicle interface experience, design for manufacturing, and ability to work independently in or leading in a multi-disciplined team environment.

  • Coordinate with System Integration and Test engineer responsible for the assembly, integration, and testing of payload & space vehicle software and mechanical aspects such as subsystems including power, attitude control, T&C (Telemetry & Command), C&DH (Command & Data Handling), and inter-subsystem interfaces to ensure all mechanical engineering requirements are met

  • Work with and ensure collaboration between a variety of Subject Matter Experts (SMEs) in various space vehicle subsystems and environments (thermal, EMI/EMC/ESD, dynamics etc.)

  • Perform hardware/software requirements definition, decomposition, allocation, management, verification, and validation

  • Work with SMEs to define and ensure mechanical interface requirements are properly flowed down to each subsystem and coordinated between subsystems including key suppliers such as for bus components or subsystems

  • Define and establish spacecraft technical baseline to meet program customer requirements.

  • Work with SMEs to ensure subsystem verification testing and analysis is performed with appropriate modeling of inter-subsystem interfaces

  • Participate and present information for internal and external technical reviews including peer reviews, requirements reviews, design reviews, qualification reviews and customer System Requirements Review (SRR), Preliminary Design reviews (PDR), Critical Design Reviews (CDR) and Technical Interchange Meetings (TIM)

  • Support subsystem and system level mechanical testing including data reviews, anomaly investigations and RCCA (Root Cause Corrective Action) closure

  • Contribute to the development of detailed work instructions, processes and procedures directing the assembly and test of launch space vehicle (SV) systems, ensuring consistent application of assembly processes and philosophies across all products

  • Support program technical and management leadership, as required

  • Support and lead technical discussions with customers, as required


  • Bachelor’s Degree and a minimum of 12 years of prior relevant experience. Graduate Degree and a minimum of 10 years of prior related experience.
