Senior Electrical Engineer – High-Speed Digital, RF Hardware Integration

Role Overview

• Design high-speed digital and mixed-domain PCBs for RF and multi-sensor platforms.
• Architect board-level hardware around FPGAs/SoCs, RF transceivers, ADCs/DACs, MCUs, memory, clocks, power, and high-speed interconnects.
• Create schematics, BOMs, layout constraints, design notes, and release packages using tools such as Altium.
• Support interfaces such as PCIe, USB, Ethernet, SFP/QSFP28, JESD204, QSPI, I2C, RS-422, and similar board-level buses.
• Develop clocking, synchronization, reset, and power-sequencing approaches for coherent sensors and high-throughput data paths.
• Collaborate with FPGA and embedded software engineers to define clean hardware interfaces, bring-up paths, debug hooks, control signals, and data-movement needs.
• Collaborate with RF engineers on mixed-domain partitioning, RF/digital layout, transceiver integration, signal integrity, power integrity, and EMI/EMC considerations.
• Bring up new boards using oscilloscopes, logic analyzers, spectrum analyzers, VNAs, power analyzers, protocol analyzers, and related lab tools.
• Troubleshoot hardware, firmware, and system-level issues from bench prototypes through integration and field testing.
• Iterate designs quickly based on test results, evolving requirements, manufacturing feedback, and field observations.
• Support design reviews, DFM/DFT activities, vendor coordination, prototype builds, and transition from proof-of-concept hardware toward reusable platform designs.
• Keep schematics, layout files, test plans, bring-up notes, validation results, and engineering documentation clear and current.

Requirements

• Minimum Eligible to obtain a U.S. Security Clearance
• U.S. Citizenship required.
• B.S. in Electrical Engineering, Computer Engineering, or related technical field.
• 5+ years of experience designing high-speed digital, mixed-signal, embedded electronics, FPGA/SoC carrier boards, RF-adjacent hardware, or similar systems.
• Strong schematic capture and PCB design experience; Altium experience preferred.
• Working knowledge of high-speed serial design, differential signaling, controlled impedance, stack-up planning, timing, clocking, reset, and board-level signal integrity.
• Experience with power supplies, power sequencing, power integrity, thermal constraints, and dense embedded hardware design.
• Ability to design hardware that supports FPGA/SoC integration, ADC/DAC or sensor interfaces, memory, PCIe/DMA-capable data paths, and application-facing control needs.
• Hands-on board bring-up and troubleshooting experience with common lab and test equipment.
• Ability to read datasheets, schematics, layout constraints, interface specifications, and system requirements, then turn them into practical hardware designs.
• Clear communicator who documents decisions and works well across electrical, FPGA, embedded software, RF, DSP, mechanical, and systems teams.
