Digital Design Engineer(Mid-Career)High Speed, Mixed Signal

ATC is seeking a highly motivated, mid-career Digital Design Engineer to lead and contribute to the development of advanced, high-speed, mixed-signal and digital FPGA-based electronics for next-generation sensing and processing systems. This role is part of ATC’s Advanced Solutions Group, delivering mission-critical electronics for space and airborne platforms. In this position, you will play a key technical role in architecting, designing, and implementing complex digital and mixed-signal systems utilizing advanced processors, high-speed data converters, high-bandwidth memories, and FPGAs. You will drive technical decisions from system concept through design, verification, production, and operational deployment., * Lead and contribute to digital and mixed-signal system architecture and definition, balancing performance, reliability, power, and environmental constraints

• Design, simulate, and verify high-speed digital and mixed-signal circuits, including high-speed serial interfaces, clocks, data converters, and memory subsystems
• Develop and implement high-performance FPGA designs for real-time digital signal processing, data movement, and control functions
• Perform and guide signal integrity, power integrity, and timing analysis for high-speed board-level designs
• Define and manage power budgets and contribute to robust designs for radiation-tolerant and mission-critical environments
• Collaborate closely with systems, electrical, RF, mechanical, thermal, software, and firmware teams to ensure cohesive system implementation
• Support designs through manufacturing, integration, test, and operational support, including failure analysis and design refinements
• Provide technical mentorship to early-career engineers and contribute to design reviews and best-practice development

• B.S. or M.S. in Electrical Engineering or a closely related discipline
• 5 or more years of experience in digital hardware design, with significant exposure to high-speed and mixed-signal systems
• Strong experience designing and implementing FPGA-based systems, including HDL development, simulation, synthesis, and hardware bring-up
• Mixed-signal board design involving high-speed ADCs, DACs, precision clocks, and power regulation
• Hands-on experience with high-speed digital interfaces ( 250 MHz clocks, multi-Gbps serial links, DDR, ADC/DAC interfaces, or similar)
• Proficiency in signal integrity, timing, and power integrity analysis at the board and system level

Preferred / Desired Experience

• High-reliability or mission-critical electronics (space, airborne, defense, or aerospace systems)
• Single Event Effects (SEE) mitigation and radiation-tolerant or radiation-aware design practices
• Experience developing and integrating DSP algorithms (e.g., filtering, modulation, data conditioning) in FPGAs
• Collaboration across hardware, firmware, and software boundaries in complex system environments
• Experience supporting designs through production and operational lifecycle phases
