Position Summary

The Principal Electrical Design Engineer - Compute is responsible for the architecture, design, analysis, development, and verification of advanced aerospace computing electronics. This role supports new product development and evolution of Trident's space computing product line, including flight computers, processor and FPGA-based electronics, daughter cards, interface electronics, and supporting circuitry.

The Principal Electrical Design Engineer serves as a senior technical contributor throughout the hardware development lifecycle, from architecture and component selection through schematic design, analysis, PCB layout oversight, prototype bring-up, qualification, and production transition.

The ideal candidate has deep hands-on electrical design experience and is comfortable independently solving complex board-level problems involving high-speed digital interfaces, power, signal integrity, radiation environments, and aerospace reliability requirements.

 Duties and Responsibilities

• Architect and design new aerospace computing electronics, including processor-based systems, FPGA-based systems, daughter cards, interface electronics, and supporting circuitry.
• Develop electrical architectures, schematics, component selections, interface definitions, and detailed board-level designs.
• Perform or lead electrical analyses including worst-case circuit analysis (WCCA), component derating, power analysis, timing analysis, signal integrity (SI), and power integrity (PI).
• Design and analyze high-speed digital interfaces such as DDR memory, PCIe, Ethernet, LVDS, and other high-speed serial and parallel interfaces.
• Design supporting analog and mixed-signal circuitry including power conversion, sequencing, monitoring, reset, clocking, sensor, and interface circuits.
• Develop radiation-effects-mitigation approaches appropriate for space electronics, including component selection, circuit-level mitigation, fault tolerance, and analysis of radiation-induced failure modes.
• Support radiation-effects analysis and testing, including consideration of total ionizing dose (TID), single-event effects (SEE), and other applicable space-environment effects.
• Select electrical components based on performance, reliability, radiation tolerance, lifecycle, availability, manufacturability, and program requirements.
• Develop and maintain component derating, parts analysis, and engineering documentation supporting flight hardware designs.
• Provide technical direction and oversight for PCB layout, including high-speed routing, controlled impedance, differential pairs, memory interfaces, power distribution, grounding, stack-up, and EMI/EMC considerations.
• Perform design trade studies balancing performance, SWaP-C, reliability, radiation tolerance, schedule, manufacturability, and lifecycle considerations.
• Lead and participate in schematic reviews, peer reviews, design reviews, and technical trade studies.
• Support prototype hardware bring-up, board-level debug, characterization, integration, and verification using laboratory instrumentation.
• Troubleshoot complex electrical issues involving processors, FPGAs, memory, power systems, high-speed interfaces, clocks, communication interfaces, and board-level circuitry.
• Develop hardware verification strategies and support development of engineering test plans, procedures, and acceptance criteria.
• Support environmental and qualification testing including thermal, thermal-vacuum, vibration, EMI/EMC, and radiation testing, as applicable.
• Investigate hardware failures and anomalies through structured root-cause analysis and recommend corrective actions.
• Work closely with FPGA, embedded software, mechanical, integration and test, GSE, manufacturing, quality, and program personnel throughout product development.
• Support transition of new designs from engineering development into repeatable production.
• Mentor junior electrical engineers and provide technical guidance on design practices, analysis, troubleshooting, and hardware development.
• Support customer technical discussions and design reviews as a subject matter expert for electrical hardware.
• Perform other duties as assigned.

Required Qualifications
