What you will do

• Define, integrate, and verify software systems supporting commercial space station operations and infrastructure.
• Author functional, performance, safety, cybersecurity, and interface requirements using a model-based approach.
• Maintain bidirectional traceability from concepts of operations through system, software, design, and test stages.
• Define interface control documents, message schemas, timing budgets, failure behaviors, and software architecture trades.
• Collaborate with avionics, network, FPGA, hardware, and multidisciplinary engineering teams on end-to-end integration.
• Plan verification methods and acceptance criteria, and support SIL/HIL environments, test benches, laboratories, and flight or field test readiness.

Requirements

• U.S. citizenship or permanent residency is required.
• Eligibility for access to export-controlled technical data under NASA regulations, ITAR, or EAR is required; additional export-control screening may apply.
• 10+ years of systems engineering experience on software-intensive programs, or an equivalent combination of education and experience.
• Bachelor's degree in aerospace, electrical, systems engineering, computer science, or another technical or engineering field.
• Experience authoring and managing software and system requirements, maintaining lifecycle traceability, defining interfaces, and planning verification activities.
• Hands-on MBSE experience with SysML or an equivalent modeling language, plus proficiency with a requirements management tool such as Jama, DOORS, or Innoslate.

Nice to have

• Experience with aerospace, spaceflight, human-rated, or safety-critical systems.
