As a Senior Staff Electrical Hardware Design Engineer, you will take ownership of full‑cycle PCBA designs, from early concept to flight readiness and in‑orbit debug. 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 areas and drive projects across disciplines to help facilitate ideas, product readiness, and conduct reviews.

• Own the full electrical design lifecycle for complex spaceflight hardware: concept of operations, requirements engineering, schematic capture, layout, bring‑up, test, manufacturing handoff, and in‑orbit debug
• Develop robust analog/digital designs for mission‑critical systems under environmental and performance constraints
• Organize collaborative cross‑disciplinary design reviews sharing feedback and shaping solutions with a team of experienced engineers
• Provide critical input to schedule planning as well as mission and system requirements
• Lead hardware requirements and process improvements (Altium, DFM, DFT)
• Lead board‑level bring‑up and debugging, integrating firmware/software/FPGA with embedded systems
• Define test plans and verification strategies that meet flight readiness requirements
• Play a key role in scaling up our manufacturing facility, bringing hardware from prototype to low‑volume production
• Lead collaboration across teams – mechanical, harness, RF, software, FPGA/SoC, and systems to ensure seamless integration
• Mentor early‑ and mid‑career engineers contributing to internal process improvements and elevating the overall quality of the team
• Engage with external vendors and contract manufacturers, ensuring delivery quality, resolving DFM/DFT issues, and ensuring on‑time delivery
• Drive failure analysis and root‑cause investigations across flight or test anomalies

• Consistently deliver flight‑quality hardware on schedule with minimal oversight
• Get things done, align with stakeholders, and document concisely
• Proactively identify and articulate system‑level risks and drive mitigations early
• Communicate across hardware/software and cross‑functional gaps with confidence and clarity
• Make thoughtful trade‑offs in constrained environments and justify them with data
• Show curiosity about advanced areas such as architecture optimization or radiation mitigation, even if those areas are outside your scope…
