Staff Design Verification Engineer – High‑Speed Interface Protocols

Key Responsibilities • Build and debug functional verification environments at IP and subsystem levels. • Serve as the protocol expert, providing clarity on expected behaviors of AMBA and high‑speed interfaces (PCIe, UCIe, SerDes, etc.). • Debug mismatches between RTL, DV models, and specifications, ensuring functional correctness and compliance. • Develop and maintain UVM‑based testbenches, scripts, and flows to automate verification compile/run cycles. • Triage and root‑cause simulation failures, track bugs, and drive closure with cross‑functional teams. • Optimize simulation runtime, capacity, and compile turnaround for large‑scale designs. • Maintain detailed documentation of methodologies, flows, and known issues. Requirements • Bachelor’s or Master’s degree in Electrical or Computer Engineering (or related field). • 7+ years of experience in ASIC/SoC design verification, with recent focus on high‑speed protocols (PCIe, UCIe, SerDes). • Deep expertise in on‑chip bus protocols (AXI, CXS, AHB, CHI, etc.). • Proven experience developing UVM‑based testbenches and driving coverage‑driven sign‑off flows. • Strong understanding of digital design fundamentals and SoC microarchitectures. • Proficiency in Verilog/SystemVerilog and simulation tools (VCS, Xcelium, Questa). • Exceptional debugging and problem‑solving skills, with the ability to work independently on complex challenges. Preferred Qualifications • Experience using AI‑assisted tools for design verification and regression analysis. • Familiarity with version control systems (Git, Perforce) and job scheduling frameworks (LSF, Grid Engine). • Strong scripting skills in Perl, Python, or TCL for automation and debug workflows. • Excellent communication and documentation skills. Why Semidynamics • Join one of Europe’s most promising deep‑tech semiconductor startups, building AI chips from silicon to systems. • Accelerated career growth and technical ownership. • Hybrid work model: 4 days in the Barcelona office (city center), 1 day WFH, plus 1 week of “work from anywhere.” • Competitive compensation and benefits. • A collaborative, technically driven environment that values clarity, ownership, and innovation.
