Position Overview
We are seeking a High-Speed Digital Hardware Engineer to support the development and testing of advanced electrical subsystems and PCBAs for next-generation optical communications systems, including space-based applications.

This role involves contributing to and leading the integration and testing of complex hardware systems combining high-speed digital, analog, and electro-optic components. The engineer will also influence system architecture and support future hardware design efforts.

Key Responsibilities

• Support and lead integration and testing of electrical subsystems for advanced communications systems
• Debug complex electrical issues in collaboration with cross-functional engineering teams (hardware, firmware, mechanical, optical)
• Develop integration and test procedures
• Contribute to system architecture and future high-speed digital hardware designs
• Perform electrical design, analysis, and validation for next-generation systems

Required Qualifications

• Bachelor’s degree in Electrical Engineering, Computer Engineering, or related field
• 5+ years of experience designing and testing complex mixed-signal hardware
• 5+ years of experience with:
  • Component selection, schematic capture, PCB layout, and board bring-up
  • High-speed digital systems targeting SoCs or FPGAs (including clocking, power, and high-speed interfaces)
  • Working in cross-functional teams (e.g., mechanical, RF)
  • Lab equipment (e.g., high-speed oscilloscopes, power supplies, spectrum analyzers, signal generators)
• 3+ years of experience with programming or scripting (e.g., Python, C/C++, Bash)
• 1+ year of experience with embedded or desktop Linux

Preferred Qualifications

• Master’s degree in Electrical Engineering, Computer Engineering, or related field
• Experience with high-reliability hardware design (e.g., aerospace or defense environments)
• Experience designing and testing hardware for space or similarly demanding environments
• Familiarity with optical or RF communication systems and digital signal processing
• Experience translating system requirements into hardware specifications (e.g., data converters, signal chains)
• Experience with modern high-speed interfaces and components, including:
  • SERDES
  • RF ADCs/DACs
  • DDR memory
• Experience with FPGA-based systems (e.g., AMD/Xilinx platforms)
• Familiarity with PCB design tools (e.g., Mentor Graphics Xpedition or similar)

Additional Information

• Ability to obtain a security clearance is required; active clearance is a plus
• Role is primarily onsite due to the nature of hardware development and testing
• Limited remote flexibility may be available during certain project phases
• Interview process includes an initial virtual screening followed by a panel interview (onsite or virtual depending on candidate location)
