Advanced ASIC FPGA Verification Engineer for Crypto and Cross Do

Basic Qualifications

Bachelor's degree in Electrical or Computer Engineering, or a related Science, Engineering or Mathematics field, plus a minimum of 5 years of relevant experience; or Master's degree plus a minimum of 3 years of relevant experience.

CLEARANCE REQUIREMENTS: Department of Defense Secret security clearance is required at time of hire. Applicants selected will be subject to a U.S. Government security investigation and must meet eligibility requirements for access to classified information. Due to the nature of work performed within our facilities, U.S. citizenship is required.

Responsibilities for this Position

What You'll Do

• Take ownership, lead, develop and maintain UVM-based and non-UVM-based verification environments for complex FPGA designs including cryptographic engines, protocol interfaces, and system-level integration testbenches
• Create comprehensive verification plans with functional coverage models, coverage goals, and closure criteria aligned to design specifications
• Implement constrained-random stimulus generators, monitors, scoreboards, and functional coverage collectors using SystemVerilog, VHDL and UVM
• Drive code coverage (statement, branch, condition, expression, toggle) and functional coverage to closure, analyzing coverage holes and developing targeted stimulus to fill gaps
• Develop and maintain automated simulation regression suites that run across multiple test configurations and random seeds
• Build and improve CI/CD pipelines for automated verification workflows -- including nightly regression runs, coverage trend tracking, and automated results reporting using Jenkins, GitLab CI, or similar platforms
• Perform assertion-based verification (ABV) using SystemVerilog Assertions (SVA) to capture protocol rules, interface contracts, and design invariants
• Debug complex design issues using waveform analysis (QuestaSim, Vivado), assertion failures, and coverage-driven investigation
• Collaborate closely with FPGA design engineers during architecture definition to ensure designs are verification-friendly and observable
• Review and contribute to design specifications, interface control documents, and verification closure reports
• Mentor junior verification engineers on UVM methodology, coverage-driven verification practices, and debugging techniques
• Support formal verification activities including property checking, connectivity verification, and equivalence checking where applicable

Required Qualifications

• Strong proficiency in SystemVerilog for verification, VHDL for verification including constrained-random stimulus, functional coverage, and assertions
• Hands-on experience with UVM (Universal Verification Methodology) including environment architecture, component development, and sequence libraries
• Experience with industry-standard simulation tools: QuestaSim/ModelSim Simulators
• Demonstrated ability to develop verification plans, define coverage models, and drive coverage to closure
• Experience with code coverage metrics (statement, branch, condition, expression, toggle) and coverage analysis workflows
• Proficiency in VHDL and/or Verilog for reading and understanding design RTL
• Experience with waveform debugging and signal-level analysis
• Understanding of AXI-Stream, AXI4, and similar on-chip bus protocols from a verification perspective
• Knowledge of clock domain crossing (CDC) verification concepts and metastability analysis
• Strong written and verbal communication skills for verification plans, coverage reports, and technical presentations
• S. Citizenship and ability to obtain/maintain a Secret security clearance

Preferred Qualifications

• Experience verifying cryptographic hardware implementations (AES, GCM, SHA, ECC, RSA, or similar)
• Experience with CI/CD pipeline development and maintenance for FPGA verification (GitLab CI, GitHub Actions) -- including automated regression management, seed management, and coverage merging
• Proficiency in scripting languages (Python, Tcl, Bash, Perl) for verification automation, log parsing, and results analysis
• Experience with Xilinx Vivado Design Suite and FPGA-specific verification challenges (timing simulation, post-synthesis/post-route verification)
• Knowledge of CDC analysis tools (Questa CDC) and lint/design rule checking tools
• Experience with emulation or prototyping platforms for hardware-in-the-loop verification
• Knowledge of AXI protocol specification and Questa verification IP (QVIP) usage for protocol compliance checking
• Experience with version control (Git), code review processes, and collaborative development workflows
