Performs survivability analyses for satellite systems across contamination, micrometeoroid, radiation, EMI/EMC, and other space-environment disciplines. Executes material and subsystem tests in simulated space environments, documents results, supports compliance documentation and test planning, and participates in multidisciplinary design reviews involving cost, weight, and risk trade-offs. The role is fully onsite in El Segundo, California, supporting national security space missions.

Design and develop advanced digital electronics hardware for aerospace applications, ensuring compliance to specifications and collaborating across teams.

Lead development and integration of fault and autonomy architectures for first-of-kind space vehicles. Perform failure analyses (FMECA, fault tree), write onboard fault protection software requirements, design autonomy and ground recovery procedures, coordinate stakeholders and customers, present reviews, and provide occasional on-call anomaly support. Ensure redundancy and fault tolerance across spacecraft and ground systems.

Leads the design, development, integration, testing, and performance analysis of SIGINT systems for airborne and space missions. Collaborates with cross-functional teams on sensor and data processing integration, validates system data, creates technical and operational documentation, assesses risks, supports project planning, recommends system improvements, and mentors junior engineers.

Manage supplier performance, supply and demand, schedules, quality, delivery and financials. Lead supplier performance teams, negotiate pricing and contracts, prepare and execute contractual agreements, manage risk and supplier improvement activities, consult with customers on supplier issues, and participate in supply chain process improvements.

Designs, develops, tests, integrates, debugs, and maintains non-embedded software for classified defense programs. Translates customer requirements into software architectures, interfaces, algorithms, and designs; supports system integration and lifecycle processes. The role also handles technical issues, improves development processes and metrics, conducts software research, and ensures compliance with quality, safety, regulatory, and customer standards. Work involves Java, ReactJS, DevOps tools, Agile methodologies, and classified-program environments.

Develop RF and electrophysics architectures, requirements, simulations, trade studies, gain-loss budgets, test procedures, and validation plans for aerospace and defense systems. The engineer supports RF product development throughout the lifecycle, including qualification, production, and environmental performance analysis. This fully onsite role requires U.S. citizenship, eligibility for a Top Secret clearance, a bachelor’s degree, and at least five years of related experience. Travel may be required up to 10%.

Design, implement, test, and maintain real-time/near-real-time software simulation models and system-level simulators for satellite mission rehearsal and operator training. Translate customer requirements, integrate and debug simulation scenarios, collaborate with multidisciplinary teams, and create automation tools for configuration and deployments in an agile CI/CD environment.

Design, implement, integrate, test, and debug spacecraft dynamic models and interface software for real-time simulators and emulators. Support hardware/software integration, produce design and test documentation, collaborate with multidisciplinary teams, support STE testbeds, and provide simulation operation and maintenance support in an agile CI/CD environment.

Lead design and technical strategy for spacecraft Command & Data Handling architectures. Perform trade studies, requirements and ICD definition, signal integrity/EMI analysis, vendor selection, integration/test oversight, FDIR collaboration, and mentor engineering staff to ensure mission-ready avionics and electrical hardware.
