• Experience with requirements analysis, parts selection, trade studies, hardware architecture, and schematic capture
• Experience supporting PCB physical layout and applying appropriate design constraints
• Ability to independently support hardware checkout, troubleshooting, and integration

Digital Design Engineer IV - Approximately 8+ Years

In addition to the qualifications above:

• 8+ years of experience developing digital electronics, circuit card assemblies, and/or multi-assembly electronic systems
• Demonstrated ability to take a hardware design from requirements or initial block-diagram concept through detailed design, hardware fabrication, test, and integration
• Strong understanding of the complete PCB/CCA design process
• Advanced experience with schematic capture, design analysis, simulation, and design verification prior to hardware execution
• Experience developing complex hardware incorporating processors, FPGAs, memory, and high-speed digital interfaces
• Strong background developing multi-layer CCAs and defining or applying hardware design constraints
• Ability to provide technical direction, mentor less-experienced engineers, and lead hardware development activities
• Experience supporting programs through development and transition into production

Preferred Skills: 

• Experience designing electronics for missile, aerospace, avionics, defense, or other high-reliability applications
• Experience with high-speed digital electronics
• Experience with homogeneous or heterogeneous multiprocessor architectures
• Familiarity with FPGA development and integration
• Familiarity with embedded software and hardware/software integration
• Experience with signal integrity and/or power integrity analysis
• Experience troubleshooting prototype hardware in a laboratory environment
• Experience supporting hardware throughout the complete product development lifecycle
