Job description

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.

Key Responsibilities

• 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

Required Qualifications

• 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 (e.g., 250 MHz clocks, multi‑Gbps serial links, DDR, ADC/DAC interfaces)
• 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

Candidates must be US citizens eligible for a Top‑Secret US Government security clearance.
