JOB RESPONSIBILITIES/ Architecture & Design: Translate complex software requirements into optimized Register Transfer Level (RTL) architecture. IP Development: Design, implement, and test custom intellectual property (IP) blocks using VHDL, Verilog, or SystemVerilog. Hardware-Software Integration: Develop low-level C/C++ drivers, Linux kernel modules, and APIs to connect FPGA logic with embedded microprocessors. Verification & Testing: Write comprehensive testbenches (using UVM or SystemVerilog) and utilize hardware-in-the-loop (HIL) testing with oscilloscopes and logic analyzers. Timing Closure: Analyze and optimize logic placement, routing, and clock domains to meet strict hardware timing and power constraints. DESIRED SKILLS & EXPERIENCE/ Required Skills: Bachelor’s degree in Computer Science, Electrical Engineering, Computer Science or a related field Ability to obtain or possess a current/or recent U.S. Government Security (DoD) Clearance. U.S. citizenship is required to obtain clearance Hardware Languages: Proficiency in VHDL, Verilog, or System Verilog. Software Languages: Strong programming skills in C, C++, and scripting languages like Python or Tcl for automation. FPGA Toolchains: Mastery of vendor tools such as AMD/Xilinx Vivado, Intel Quartus, or Microchip Libero. Methodologies: Experience with High-Level Synthesis (HLS), Digital Signal Processing (DSP), and SoC architectures (e.g., ARM-Cortex embedded in FPGA). Protocols: Deep understanding of high-speed interfaces like PCIe, Ethernet (10G/100G), DDR4/DDR5, and AXI streaming. Work is based in Dayton, Ohio with periodic days at WPAFB Travel required up to 25% for customer support and presentations Desired Skills: Experience: 5+ years of hands-on experience in FPGA design and embedded software development. Domain Expertise: Industry-specific experience in areas like RF/SDR, defense, automotive (ADAS), high-frequency trading, or data centers. Physical Requirements: Ability to travel by air, car, or other transportation methods Prolonged periods of sitting at a desk and working on a computer (up to 8 hours/day) Ability to lift and carry lightweight items (e.g., laptops, demo equipment, marketing materials) up to 25 lbs. Frequent use of hands and fingers for typing, using a mouse, writing, and handling equipment. Visual acuity to read detailed technical documents, view computer screens, and operate software systems Auditory ability to participate in meetings, customer demos, and conference calls, including in potentially noisy environments (e.g., trade shows or military facilities) Mobility to move between office spaces, customer sites, conference venues, and manufacturing or lab environments Flexibility to adapt to varying work environments (e.g., corporate offices, government buildings, industrial or lab spaces) We are committed to staying rooted in our core value of Team First. For that reason, we've designed a highly competitive benefits program and supportive work environment to engage employees and their families.
