Apex Technology
Space Vehicle Systems Engineer
About this role
Apex seeks a Space Vehicle Systems Engineer to lead spacecraft architecture, requirements allocation, and cross-disciplinary integration for a classified national security satellite program. You'll drive system-level design decisions, manage interfaces across all domains, and serve as the technical bridge between engineering teams, government customers, and payload partners throughout the vehicle lifecycle.
What you'll do
- Define and maintain spacecraft architecture and requirements with full traceability from mission objectives through subsystem level
- Lead trade studies, risk analyses, and simulations to balance performance, cost, and schedule constraints
- Develop and maintain system documentation including specifications, Interface Control Documents, and technical budgets
- Coordinate cross-domain subsystem integration and enforce interface compatibility across electrical, mechanical, thermal, and software systems
- Analyze test and anomaly data to isolate issues and drive resolution with subsystem teams
- Present technical readiness and compliance at design reviews (SRR, PDR, CDR, TRR) and engage with government customers on requirements and technical issues
What they're looking for
- Systems engineering principles and V&V methodologies
- Requirements management tools (DOORS, Jira, SysML)
- Spacecraft subsystems knowledge (attitude control, power, thermal, propulsion, communications, C&DH)
- Mission analysis and modeling
- Risk management and FMEA
- Technical documentation and interface control
- Cross-functional coordination and stakeholder communication
- Industry standards (INCOSE, NASA systems engineering guidelines)
