Job description
This Principal Systems Engineer role provides technical leadership for the design, development, integration, test, verification, and sustainment of advanced space systems and satellite technologies. You will shape system architectures, drive cross-functional engineering efforts, and lead complex aerospace and defense programs from initial concept through mission deployment and operations. The position suits a strategic thinker who combines deep systems engineering expertise with hands-on experience across electrical, mechanical, software, and spacecraft subsystems, and who enjoys leading multidisciplinary teams while remaining closely engaged in the technical details that drive mission success. Responsibilities
- Lead the full systems engineering lifecycle, including requirements development, architecture definition, interface management, integration, verification, validation, and mission readiness activities.
- Develop and maintain system requirements, specifications, Interface Control Documents (ICDs), verification matrices, and technical data packages.
- Establish system architectures and technical solutions for spacecraft, payloads, ground systems, and mission operations.
- Support the design, development, assembly, integration, testing, and deployment of satellite systems and related technologies.
- Lead system-level trade studies and technical assessments to optimize performance, reliability, cost, and schedule objectives.
- Oversee subsystem integration efforts spanning electrical power systems, communications, avionics, structures, propulsion, software, and payload technologies.
- Provide technical direction and mentorship to engineers across multiple disciplines.
- Serve as the primary technical authority for system-level decisions, risk management, and engineering problem resolution.
- Drive and lead engineering reviews, including System Requirements Reviews (SRR), Preliminary Design Reviews (PDR), Critical Design Reviews (CDR), Test Readiness Reviews (TRR), Flight Readiness Reviews (FRR), and mission readiness assessments.
- Develop and execute integration, qualification, acceptance, and environmental test strategies for flight and ground hardware.
- Lead anomaly investigations, conduct root cause analyses, and implement corrective actions to ensure mission reliability.
- Ensure traceability between requirements, verification activities, and mission performance objectives throughout the program lifecycle.
- Evaluate emerging technologies and lead research initiatives focused on next-generation spacecraft and mission capabilities.
- Support rapid prototyping, technology maturation, and transition of innovative concepts into operational systems.
- Collaborate with internal and external stakeholders, customers, and mission partners to advance program objectives and resolve technical issues.
- Maintain accurate and comprehensive engineering documentation throughout the program lifecycle.
- Present technical information and program status to executive leadership, customers, partners, and formal review boards.
- Ensure effective communication and coordination across cross-functional teams in a fast-paced development environment.
