Description

Design and architect complex high-speed digital circuit cards for aerospace and defense systems, driving work from architecture and schematic capture through PCB layout, integration, and first-pass hardware success. Work with multi-lane high-speed serial interfaces, Ethernet, fiber and copper connectivity, multiple FPGAs and SoCs, and DDR5/DDR6-class memory. Solve challenging signal-integrity, timing, crosstalk, and electrical-interference problems with strong ownership.

Responsibilities

• Architect and design complex high-speed digital circuit cards
• Develop schematics, select components, and define board-level interfaces and design requirements
• Design multi-lane high-speed serial interfaces (Ethernet, fiber, copper)
• Integrate multiple FPGAs, complex SoCs, and DDR5/DDR6 or comparable memory
• Analyze and resolve signal integrity, timing, crosstalk, and electrical interference issues
• Partner with ECAD and PCB layout engineers on stackups, routing constraints, and placement/layout requirements
• Lead technical reviews, design trade studies, risk assessments, and hardware troubleshooting
• Support board bring-up, integration, testing, debugging, and validation in the lab
• Collaborate with FPGA, software, systems, mechanical, and test engineers
• Create and maintain schematics, design documentation, BOMs, analysis results, and test procedures
• Drive first-pass hardware success while meeting program schedules

Requirements

• Bachelor’s degree in Electrical Engineering, Computer Engineering, or related discipline
• 5+ years of experience designing complex digital hardware or circuit-card assemblies
• Hands-on high-speed digital board design experience from schematic capture through hardware bring-up and validation
• Experience designing high-speed serial interfaces with multiple lanes per card
• Experience integrating multiple FPGAs, complex SoCs, and high-performance memory such as DDR5 or DDR6
• Strong understanding of signal integrity, timing, crosstalk, electrical interference, and board-level design constraints
• Experience collaborating closely with ECAD and PCB layout engineers
• Ability to lead technical decisions, resolve complex hardware issues, and deliver under demanding schedules
• Ability to work onsite in Cedar Rapids, Iowa
• U.S. citizenship and ability to obtain and maintain U.S. security clearance

Benefits

• Competitive pay
• Comprehensive medical/dental/life and disability coverage
• 401(k) with employer match
• Professional development support
• Certification assistance and clear advancement opportunities
• Flexible, friendly, people-first workplace
