• Design System Level harnesses from power distribution to high-speed communications
• Own the harness design lifecycle and implement harness design best practices
• Collaborate across teams-mechanical, RF, electrical, and systems-to ensure seamless integration. Knowledge of industry-standard electrical design principles, to include, but not limited to electrical component selection, testing, manufacturing, and production processes
• Technical point of contact for Wire, Cable, Connector, and Harness suppliers
• Support resolving non-conformances from harness suppliers
• Provide critical input to schedule planning, hardware requirements, and process improvements
• Define test plans and verification strategies that meet flight readiness requirements
• What Success Looks Like
• You consistently deliver flight-quality harnesses on schedule with minimal oversight
• You proactively identify and articulate system-level risks and drive mitigations early
• You communicate across hardware/software and cross-functional gaps with confidence and clarity
• You make thoughtful trade-offs in constrained environments and justify them with data
• You show curiosity about advanced areas like architecture optimization or radiation mitigation, even if they're outside your scope for now
