Job description

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.
