Hardware Design Engineer

GCS; Redmond (WA); On-site; USD 120,000 - 180,000; Full time

Job summary

GCS is seeking a Senior Hardware Development Engineer to design and bring-up advanced phased-array payload electronics for next-generation satellite broadband. The role blends ownership of hardware design with extensive hands-on lab work, taking products from schematic through validation and into manufacturing.

Ideal candidates have 8+ years in board-level hardware, experience with high-speed digital interfaces, and strong SI/PI skills.

Qualifications

• 8+ years of board-level electrical hardware design experience.
• Strong hands-on lab and hardware debugging expertise.
• Experience with high-speed digital technologies such as: PCIe, DDR, Ethernet, JESD204, SerDes interfaces.
• Knowledge of signal integrity, power integrity, and hardware validation.
• Full product lifecycle experience from design through manufacturing support.
• Bonus points for Satellite, aerospace, or space hardware experience.

Responsibilities

• Develop phased-array payload electronics that power satellite communications.
• Own hardware design from schematic to bring-up with hands-on lab work.
• Work with thousands of onboard components and multi-gigabit interfaces.
• Ensure hardware validation and manufacturing support throughout the product lifecycle.

Job description

Do you know: Every second, satellites orbiting Earth are helping millions of people stream content, make video calls, navigate cities, and connect to the internet from some of the most remote locations on the planet.

But the main Fun Fact is that, only a handful of companies worldwide are designing and deploying satellite broadband hardware at this Scale.

And We're #HIRING Senior Hardware Development Engineers to support the next-generation satellite internet initiative focused on delivering global broadband connectivity and enabling future direct-to-device smartphone communication. With hundreds of satellites already in orbit, launch activity accelerating, commercial service ramping up, and next-generation platforms under development, this is one of the most ambitious hardware programs in the world today.

What You'll Be Working On

The team develops the phased-array payload electronics that power satellite communications.

Think:

• Thousands of onboard components
• Multi-gigabit high-speed interfaces (~25Gbps+)
• Space-bound hardware requiring rigorous validation

This role combines hardware design ownership with significant hands-on lab work, making it ideal for engineers who enjoy taking products from schematic to successful bring-up.

We're Looking For:

• 8+ years of board-level electrical hardware design experience
• Strong hands-on lab and hardware debugging expertise
• Experience with high-speed digital technologies such as: PCIe, DDR, Ethernet, JESD204, SerDes interfaces
• Knowledge of signal integrity, power integrity, and hardware validation
• Full product lifecycle experience from design through manufacturing support
• Bonus points for someone with Satellite, aerospace, or space hardware experience

Why This Opportunity?

This isn't just another hardware role.

You'll be working on technology that leaves the lab, launches into orbit, and becomes part of a global communications network. Few engineers get the chance to influence hardware at this scale while remaining deeply involved in both design and hands-on validation.

If you're passionate about complex hardware, high-speed electronics, and building technology that literally reaches space, I'd love to connect.
