Quest Defense Systems and Solutions is seeking a motivated

Digital Design Electrical Engineer to support the design and development of cutting-edge digital electronics for missile guidance, video processing, and digital signal processing applications. You will collaborate with multidisciplinary engineering teams to create advanced digital circuits using high‑speed processors, FPGAs, configurable logic, and multiprocessor architectures.

This position involves full lifecycle hardware ownership—from requirements and architecture through design, simulation, integration, and test.

We are hiring Electrical Engineers at various levels!

Location:

Onsite Tucson, AZ.  Relocation assistance is available

Citizenship:

Due to the nature of the work, US Citizenship is required.

Clearance:

Active DoD Security Clearance

What you will be doing:

• Design, analyze, simulate, test, and integrate digital electronic modules and circuit card assemblies (CCAs) for missile applications.
• Develop complex hardware designs incorporating processors, FPGAs, memory devices, and high‑speed interfaces such as PCIe, Ethernet, I2C, SPI, and UART.
• Perform requirements creation and analysis, parts selection, and system‑level trade studies.
• Create system architectures and block diagrams.
• Conduct schematic capture and support PCB layout development, including applying design constraints and performing signal/power integrity analysis.
• Execute lab bring-up, hardware checkout, integration, and functional verification using test plans and standard lab equipment.
• Collaborate closely in a team‑based engineering environment to deliver high‑reliability solutions.
• (For senior-level candidates) Lead development efforts from concept through production; provide technical oversight and mentoring.

Qualifications You Must Have:

• Experience levels can be flexible — the combined job covers 2-8+ years of experience
• Experience designing and developing electronics circuit designs and multi‑assembly hardware systems.
• 8+ years and ability to drive hardware from concept to production
• Proficiency with electronic design and simulation tools for schematic creation, PCB layout, and signal/power integrity analysis.
• Experience developing multi‑layer PCBs and complex CCAs.
• Ability to perform hands-on lab testing, troubleshooting, and integration.

Preferred Qualifications:

• Background in FPGA or embedded software development.
• Experience designing within high‑reliability or defense‑related environments.
• Ability to lead programs or technical teams (for senior-level roles).
• Verification using emulation platforms such as Veloce.
• The QDSS Advantage: At QDSS, our advantage is purpose-driven work, collaborative teams, and complex challenges that push boundaries and build lasting impact. You’ll grow your career while contributing to mission-critical programs that demand excellence and shape the future.
