Sr Hardware Development Engineer

GCS Recruitment; Issaquah (WA); On-site; USD 120,000 - 190,000; Full time

Job summary

GCS Recruitment seeks a senior EE to join a satellite hardware team designing phased-array antenna electronics. You will lead board bring-up, validate high-speed assemblies, and work closely with the design and RF/antenna teams in the lab.

You will own verification campaigns, plan debugging, and contribute to next-generation schematic/layout while supporting manufacturing as needed.

Qualifications

• Board-level design experience with dense multilayer PCBs.
• Hands-on lab bring-up, debug and validation with oscilloscopes and high-speed test gear.
• Experience with SerDes/interfaces (e.g., JESD204, PCIe, 25G+ Ethernet, DDR).
• Full lifecycle experience: design through manufacturing support.
• Bachelor or higher in EE (BSEE or MSEE) or equivalent experience.

Responsibilities

• Lead bring-up of newly fabricated boards: power-on, section-by-section checkout, first-time debug to root cause.
• Plan and run design verification/validation campaigns - high-speed link testing, power measurements, functional test - and document results to program standards.
• Partner daily with the design team; drive fixes into the next board revision.
• Contribute to schematic and layout work on next-generation boards as bandwidth allows.
• Hand off validated hardware to the RF/antenna team and support their measurement needs.

Job description

Job role:

The team designs the satellites' phased-array antenna electronics: meter-wide, 20+ layer boards carrying thousands of components - including three families of Amazon custom silicon (beamforming, modem, network processing) - linked by ~25 Gbps high-speed digital buses. Boards are coming back from fabrication faster than the design team can validate them. That's where you come in: senior EEs who can do real board design and own hardware in the lab.

• Lead bring-up of newly fabricated boards: power-on, section-by-section checkout, first-time debug to root cause.
• Plan and run design verification/validation campaigns - high-speed link testing, power measurements, functional test - and document results to program standards.
• Partner daily with the design team; drive fixes into the next board revision.
• Contribute to schematic and layout work on next-generation boards as bandwidth allows.
• Hand off validated hardware to the RF/antenna team and support their measurement needs.

What we're looking for

• Experience of EE board-level design: schematic capture, complex dense multilayer PCBs, power delivery and sequencing.
• Hands-on lab strength - the heart of this role: board bring-up, debug, and validation; fluency with oscilloscopes, logic/protocol analyzers, and high-speed test gear.
• High-speed digital experience: multi-gigabit SerDes/interfaces (e.g., JESD204, PCIe, 25G+ Ethernet, DDR) and signal/power integrity awareness.
• Full lifecycle experience: design - build - bring-up - validation - manufacturing support.
• BSEE or MSEE (or equivalent experience).

Nice to have

• Satellite, aerospace, or space-qualification experience; phased-array or radar hardware exposure.

Boards built around custom ASICs/SoCs; RF familiarity as a secondary skill; FPGA familiarity; Python bench automation
