The posting

Unlock the power of Safety and Mission Critical Engineering with QDSS. We are seeking exceptional individuals to join our elite team- where your expertise will make an impact that matters. Elevate your career in a company dedicated to excellence and the pursuit of safety and mission success.

Quest Defense Systems & Solutions is seeking a Senior High-Speed Digital Hardware Engineer to design complex circuit cards for advanced aerospace and defense systems. You’ll work with high-speed serial interfaces, multi-lane architectures, Ethernet, fiber and copper interfaces, multiple FPGAs and SoCs, and advanced DDR5/DDR6 memory.

As an early senior member of the team, you’ll help establish the technical direction and drive designs from architecture and schematic capture through PCB layout, integration, and first-pass hardware success. This is an excellent opportunity for a hands-on engineer who enjoys solving challenging signal-integrity problems and taking meaningful ownership of critical hardware designs.

This position is based in Cedar Rapids, IA. Relocation assistance is available.

U.S. citizenship and the ability to obtain a Secret clearance are required. Active Secret clearance is preferred.

What You’ll Do

  • Architect and design complex high-speed digital circuit cards for aerospace and defense applications.
  • Develop schematics, select components, and define board-level interfaces and design requirements.
  • Design high-speed serial interfaces with multiple data lanes, including Ethernet, fiber, and copper connectivity.
  • Integrate multiple FPGAs, complex SoCs, and DDR5/DDR6 or comparable high-performance memory.
  • Analyze and resolve signal-integrity, timing, crosstalk, and electrical-interference challenges.
  • Partner closely with ECAD and PCB layout engineers to define stackups, routing constraints, placement, and layout requirements.
  • Lead technical reviews, design trade studies, risk assessments, and hardware troubleshooting activities.
  • Support board bring-up, integration, testing, debugging, and validation in the lab.
  • Collaborate with FPGA, software, systems, mechanical, and test engineers to deliver cohesive system solutions.
  • Create and maintain schematics, design documentation, bills of materials, analysis results, and test procedures.
  • Drive first-pass hardware success while meeting demanding technical and program schedules.

Required Qualifications:

  • Bachelor’s degree in Electrical Engineering, Computer Engineering, or a related discipline.
  • 5+ years of experience designing complex digital hardware or circuit-card assemblies.
  • Hands-on experience with high-speed digital board design, 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 the ability to obtain and maintain a U.S. security clearance.

Preferred Qualifications:

  • Active Secret security clearance.
  • Master’s degree in Electrical Engineering, Computer Engineering, or a related field.
  • Previous experience developing hardware for aerospace or defense applications.
  • Experience with schematic and PCB design tools such as Cadence, Mentor Graphics, or Altium.
  • Experience with Ethernet and fiber and copper communication interfaces.
  • Familiarity with signal- and power-integrity analysis tools and techniques.
  • Hands-on experience using oscilloscopes, logic analyzers, and other high-speed debugging equipment.
  • Knowledge of DO-160, MIL-STD, EMI/EMC, or environmental qualification requirements.
  • Experience serving as a technical lead for complex circuit-card development.
  • Experience adopting and/or integrating emerging technologies (e.g., generative AI, automation platforms, digital assistants) into day-to-day operations for continuous improvement.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
