The Aerospace Corporation's Experiment Lab,xLab, develops prototypes, instruments, pathfinders, and demonstration systems to address our customers' hardest problems at the speed of need. We engage with our customers to conceptualize innovative solutions and deliver impactful products for ground and space and everything in between. We are looking for a High-Speed Digital Design Engineer (Senior Member of Technical Staff/Engineering Specialist - General Integrated Circuit Design Engineering) with a passion for design, a commitment to teamwork and a desire to helpxLabmake a difference to today's challenges. We need a skilled high-speeddigitalinterface engineer to design, develop, andvalidatecutting-edgecommunication systems for space and ground applications.

This is a full-time position based inEl Segundo, CA., requiring at least 4 days onsite.

WhatYoullBe Doing

• Design and develop high-speed digital interfaces forxLabprototype systems supporting Department of Defense and civil space customers

• Perform board-level design, schematic capture, and layout coordination for Ethernet, SGMII, 1000BASE-X, and similar high-speed serial interfaces

• Conduct signal integrity analysis, testing, and troubleshooting to ensure robust performance in challenging operational environments

• Collaborate with multidisciplinary teams including RF engineers, software developers, and system architects to integrate communication subsystems

• Support hardware bring-up, validation testing, and system integration activities for flight and ground demonstration systems

• Provide technical leadership and mentorship to junior engineers on high-speed design best practices

• Duties, responsibilities, and activities may change, or new ones may be assigned as needed

• This position emphasizes the Innovation, Velocity, and Accountability Leadership Competency Model (LCM) attributes through rapid prototyping, technical excellence, and delivery of mission-critical systems

This position is available as a Sr. Member of Technical Staff or Engineering Specialist.

What You Need to be Successful

MinimumRequirements for Sr. Member of Technical Staff:

• Bachelor's, Master's, or PhD degree from an accredited program in Electrical Engineering, Computer Engineering, or related STEM discipline

• 4 or more years of professional experience in high-speed digital interface design

• Hands-ondesign and implementationexperience with Ethernet protocols (10/100/1000 Mbps), SGMII, 1000BASE-X, or similarhigh-speed serial interfaces

• Working knowledge of Ethernet PHY layer specifications and IEEE 802.3 standards

• Demonstrated experience with PCB design and layout requirements for high-speed signals including impedance control, differential pairs, and layerstackupconsiderations

• Proficiencywith signal integrity testing equipment and techniques (oscilloscopes, TDR, VNA, eye diagrams, jitter analysis, BERT, spectrum analyzers)

• Strong troubleshooting and lab debugging skills for high-speed digital systems

• Experience with schematic capture and PCB layout tools (e.g., Altium, Cadence OrCAD, Mentor Graphics)

• Ability to obtain andmaintaina security clearance, which is issued by the US government. U.S. citizenship isrequiredto obtain a security clearance.

In addition to the requirements above, the minimum requirements for an Engineering Specialist are:

• 6 or more years of professional experience in high-speed digital interface design and implementation

• Proventrack recordof leading complex hardware development projects from concept through productionor prototype delivery

How You Can Stand Out

It would be impressive if youhaveone or more of these:

• Experience with advanced protocols such as 10GBASE-KR, PCIe, USB 3.x, or other multi-gigabit serial standards

• Proficiencywith signal integrity simulation tools (e.g.,HyperLynx, HFSS, CST, ADS)

• Experience with FPGA-based interface implementations and embedded system integration

• Knowledge of space-gradecomponentselection, radiation effects, and design for harsh environments

• Experience designing high-speed circuits for optical communications, including modulator drivers, TIAs, or SerDesfront-ends
