The Role

As a Staff Electrical Harness Design Engineer, you will take ownership of full-cycle PCBA designs, from early concept to flight readiness. You will work cross-functionally with RF, mechanical, software, FPGA/SoC, and operations teams to bring high-reliability, space-ready electronics to orbit. You will guide the Electrical Engineering team on special topics and present across disciplines to help facilitate ideas, product readiness, and conduct reviews.

Responsibilities

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

You exhibit advanced wide-ranging experience in harness engineering, using in-depth professional knowledge

You get things done, align with stakeholders, and document concisely

Requirements
