Responsibilities for this Position

What You'll Do

• Architect and implement high-performance FPGA designs in VHDL and/or Verilog targeting Xilinx and Microchip device families.
• Perform synthesis, place-and-route, and timing closure using Vivado or Libero, including advanced techniques such as pipelining, register retiming, floorplanning, and physical optimization
• Develop and execute block-level simulations using QuestaSim/ModelSim with code coverage analysis (statement, branch, condition, expression)
• Create self-checking testbenches for correctness verification
• Design high-speed interfaces for inter-module communication and system integration
• Collaborate with systems engineers, software developers, and verification engineers in an Agile development environment
• Participate in design reviews, peer code reviews, and documentation of design specifications and interface control documents
• Contribute to CI/CD pipeline development for automated synthesis, simulation regression, and coverage tracking
• Support integration and lab bring-up activities, including on-target FPGA debug using ILAs and JTAG-based tools

Required Qualifications

• Strong proficiency in VHDL and/or Verilog/SystemVerilog for synthesizable RTL design
• Hands-on experience with Xilinx Vivado Design Suite or Microchip Libero for synthesis, implementation, and timing analysis
• Experience targeting Xilinx and Microchip device families
• Ability to achieve timing closure on designs at 300+ MHz clock rates
• Experience with FPGA simulation tools (QuestaSim or ModelSim)
• Proficiency in writing self-checking testbenches with automated pass/fail determination
• Understanding of high-speed digital design principles: pipelining, clock domain crossing (CDC), metastability mitigation, and synchronous design
• Experience with AXI-Stream, AXI4, or similar on-chip bus protocols
• Ability to read and interpret timing reports, utilization summaries, and critical-path analysis output
• Strong written and verbal communication skills for design documentation and technical presentations
• S. Citizenship and ability to obtain/maintain a Secret security clearance

Preferred Qualifications

• Experience with cryptographic algorithm implementation in hardware (AES, GCM, SHA, ECC, RSA, or similar)
• Experience with high-speed serial interfaces: PCIe, Ethernet (10G/25G/100G), Fibre Channel, Aurora, or GTY/GTM transceivers
• Experience with CI/CD pipelines for FPGA development (GitLab CI) including automated synthesis and regression testing
• Proficiency in scripting languages (Tcl, Python, Bash) for build automation and design flow scripting
• Experience with version control systems (GitLab) and collaborative development workflows
• Experience with Xilinx IP cores: FIFO Generator, Clock Wizard, MIG/DDR controllers, DMA/Bridge subsystems
• Experience with embedded processors in FPGA (MicroBlaze, Zynq PS, Versal AI Engine)
