Senior Hardware Design Engineer - Satellite Payload - PCB Design & Lab

Senior Hardware Design Engineer - PCB Board Satellite Payload - Design & Lab Location: Bellevue, WA Contract: 12+ months, extendable; C2H opportunity Work Arrangement: 5 days onsite About the Role We are seeking a Senior PCB Hardware Design Engineer / Senior Hardware Development Engineer to support the development of advanced satellite payload hardware. This is a hands‑on role focused heavily on board bring‑up, hardware debug, design verification, validation, and supporting the transition of validated designs into subsequent hardware revisions. The ideal candidate will have strong board‑level design experience combined with extensive laboratory expertise and the ability to troubleshoot complex hardware issues from initial power‑on through root‑cause identification and resolution. Responsibilities Lead bring‑up of newly fabricated circuit boards, including power‑on, section‑by‑section checkout, and first‑time hardware debug through root cause. Plan and execute design verification and validation campaigns, including high‑speed link testing, power measurements, functional testing, and detailed documentation of results. Partner closely with hardware design engineers to identify issues and drive corrective actions into subsequent board revisions. Contribute to schematic capture and PCB layout activities for next‑generation hardware as project priorities and bandwidth allow. Support RF and antenna engineering teams with validated hardware and assist with their measurement and characterization requirements. Troubleshoot board‑level hardware issues using systematic debug methodologies and laboratory instrumentation. Support the complete hardware development lifecycle from design and fabrication through bring‑up, validation, and manufacturing support. Required Qualifications 8+ years of electrical engineering experience in board‑level hardware design. Strong experience with schematic capture and complex, dense multilayer PCB designs. Solid understanding of power delivery, power distribution, and sequencing. Extensive hands‑on laboratory experience with board bring‑up, hardware debug, and validation. Proficiency with oscilloscopes, logic/protocol analyzers, and high‑speed test and measurement equipment. Experience with high‑speed digital interfaces and multi‑gigabit SerDes technologies such as JESD204, PCIe, 25G+ Ethernet, DDR, or similar. Strong understanding of signal integrity and power integrity considerations. Demonstrated experience across the full hardware lifecycle: design → build → bring‑up → validation → manufacturing support. BSEE, MSEE, or equivalent practical engineering experience.
