About the role

  • Own the modeling, simulation, and optimization of the power delivery network (PDN) for accelerator boards.
  • Work closely with power, board design, and package teams to ensure stable, low‑noise power for high‑current accelerator SoCs and memory operating at leading‑edge process nodes.
  • Develop detailed PDN models for accelerator boards (VRM to die), including planes, vias, decoupling capacitors, connectors, and packages.
  • Perform frequency‑domain and time‑domain PI simulations to optimize decoupling strategy, control impedance over target frequency ranges, and minimize voltage droop, noise, and resonances.
  • Collaborate with power and PCB teams to drive layout guidelines and stack‑up decisions based on PI analysis.
  • Work with SI engineers to understand coupling between high‑speed interfaces and PDN.
  • Support power design engineers in component selection (VRMs, bulk and ceramic caps, ferrites, etc.).
  • Correlate simulation results with lab measurements (Bode plots, impedance, transient response).
  • Provide PI constraints and sign‑off criteria for new designs and design revisions.
  • Document simulation methodologies, models, and results; create reusable templates and flows for future programs.

Requirements

  • Bachelor’s or Master’s degree in Electrical Engineering or related field.
  • 3+ years of experience in Power Integrity or closely related SI/EMC roles at the board or package level.
  • Hands‑on experience with PI simulation tools (e.g., CADENCE PowerSI, PowerDC, OptimizePI, VRM simulation (SIMetrix/SIMPLIS), etc.).
  • Solid understanding of: PDN design concepts, target impedance, and decoupling strategies Transmission line theory, return paths, and via behavior.
  • Ability to interpret and generate S‑parameters and SPICE models.
  • Experience working with PCB stack‑up definitions and working with layout teams.
Benefits
  • A chance to work on one of the most transformative AI and silicon engineering companies in Europe with cutting-edge technology and industry leaders.
  • We offer a remuneration package that values your experience.
  • We believe in investing in our employees and providing them with opportunities for growth and career development.
  • Work in a hybrid environment with flexible scheduling.
  • Join an innovative team and experience company growth.
  • Opportunity to travel to other countries in Europe to meet the teams, collaborate and drive solutions.
