Senior Electrical Engineer

FullTime Lawton, OK, US

26 days ago Requisition ID: 1035

Job Purpose/Summary

The Senior Electrical Engineer supports the rapid development of next-generation, AI-enabled hardware and sensor platforms for counter-UAS (cUAS) and multi-sensor applications. This role creates the board-level hardware foundation that enables future capabilities.

The engineer will design high-speed digital, mixed-signal, and RF-supporting electronics. This includes integrating embedded processors, programmable logic, transceivers, clocks, power systems, and board-level interfaces. The engineer will support hardware from early architecture through prototype, lab test, and field validation.

Working closely with FPGA, embedded software, RF, DSP, mechanical, and application software engineers, this role helps transform new hardware concepts into modular, mission-ready capabilities. The ideal candidate will be excited to work in a fast-moving R&D environment, solve challenging hardware problems, and help build technology that moves quickly from concept to real-world impact.

Duties and Responsibilities

• 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.

Qualifications

Minimum

• Eligible to obtain a U.S. Security Clearance - U.S. Citizenship required.
• B.S. in Electrical Engineering, Computer Engineering, or related technical field.
