Job Summary:

The Space Systems Engineer (Senior/SME) provides system-wide technical leadership and management for complex spacecraft and mission programs across conceptualization, requirements definition, design, development, manufacturing, integration, testing, launch, operations, demonstration, sustainment, and documentation. This position directs cross-disciplinary systems engineering efforts, manages technical baselines, interfaces, schedules, risks, and mission readiness, and coordinates government customers, program leadership, launch providers, engineering organizations, and mission operations stakeholders. The SME serves as a senior technical authority for especially complex mission-system decisions and issues.

Key Responsibilities:

System Design & Implementation:

• Lead development and evaluation of spacecraft and mission-system architectures to satisfy mission, performance, reliability, safety, security, and interface requirements; resolve system-level trades and technical risks.
• Direct stakeholder needs analysis, requirements capture and allocation, traceability, operational concept (OPSCON/CONOPS) development, modeling and simulation, verification planning, requirements closeout, and deployment validation.
• Lead cross-organizational interface coordination across spacecraft bus, payloads, flight software, communications, ground systems, launch providers, and mission operations.
• Direct preparation, approval coordination, and configuration control of technical baselines, system specifications, interface control documents (ICDs), verification criteria, and program engineering artifacts.
• Lead architecture and technology trade studies, recommend technically sound system-level decisions, and resolve multidisciplinary design issues.

Troubleshooting & Operational Support

• Direct multidisciplinary investigation and resolution of complex spacecraft, payload, software, communications, and ground-system anomalies and interface issues.
• Manage mission operations and demonstrations for spacecraft, as applicable, including mission readiness, command-and-control coordination, anomaly response, performance monitoring, and operational reporting.
• Oversee root-cause analyses, corrective-action closure, lessons learned, and sustained system reliability improvements.

Project Management & Collaboration

• Lead system-wide technical and programmatic trade studies balancing performance, cost, schedule, resources, risks, and mission outcomes.
• Lead system integration planning, cross-site coordination, interface and configuration control, program milestones, and readiness planning; coordinate use of government launch, operational, and mission facilities as required.
• Direct technical coordination among government customers, program leadership, engineering organizations, contractors, launch providers, and mission operations teams.
• Lead technical planning, schedules, resource coordination, milestone management, risk assessments, technical briefings, and decision support for program leadership.

Documentation & Compliance

• Direct development, review, and configuration control of aerospace specifications, ICDs, requirements documents, verification procedures, engineering analyses, mission products, and program-level documentation.
• Oversee engineering data collection, processing, analysis, interpretation, and documentation; ensure the integrity and traceability of technical baselines and verification evidence.
• Ensure work complies with applicable program, customer, security, safety, quality, and regulatory requirements.
• Evaluate emerging mission technologies and systems engineering practices; mentor less experienced engineers and advise program leadership on complex technical issues.

Qualifications:

• Education: Bachelor’s degree in engineering, physics, mathematics, or a closely related technical field, or an equivalent combination of education and experience where permitted by program and contract requirements.
• Experience: Minimum 15 years of professional experience supporting aerospace systems, including spacecraft, launch, mission, ground, or related complex aerospace capabilities; including at least 5 years providing system-wide management of spacecraft programs across design, development, integration, test, launch, operations, demonstration, or sustainment.
• Clearance Requirement: Must have an active Top Secret Clearance
• Required Skills:
• Demonstrated leadership of management or systems engineering activities for space-flight hardware development, integration, operation, or maintenance.
• Demonstrated experience directing technical baselines, interfaces, requirements, reviews, mission readiness, and system-level engineering documentation.
• Advanced knowledge of space systems engineering principles and spacecraft lifecycle engineering, including architecture, requirements, integration, verification, and validation.
• Ability to direct multidisciplinary engineering teams and provide system-wide technical judgment under complex mission constraints.
• Experience assessing program risks, engineering tradeoffs, configuration management, technical issues, and corrective actions.
• Excellent executive-level technical communication, problem-solving, coordination, and stakeholder management skills.
• Ability to lead technical work across program management, government customers, suppliers, launch providers, and operations organizations.
• Required Skills:
• Deep experience across spacecraft mission lifecycles, flight and ground segments, launch interfaces, payload integration, communications, or mission operations.
• Experience leading major program reviews, mission-readiness assessments, spacecraft demonstrations, and complex multi-organization integration efforts.
• Advanced experience with model-based systems engineering, simulation, mission data analysis, test automation, or other relevant systems engineering tools.
• Relevant advanced systems engineering or program-management certifications (for example, INCOSE CSEP/ESEP or PMP), or demonstrated equivalent technical leadership.

Work Environment/Physical Requirements:

• Work is generally performed in an office or technical environment and may include on-site work at laboratories, integration and test facilities, mission operations centers, or customer/government locations.
• May require after-hours or weekend support for critical program activities, integration and test events, or mission operations.
• Some travel may be required to support customer meetings, testing, technical reviews, or program milestones.
• Ability to work at a desk and operate a computer for extended periods. Additional site-specific physical or safety requirements may apply to assigned laboratory or hardware activities.

Work Schedule:

This is a full-time position, typically working 40 hours per week. Overtime may be required depending on operational needs.
