Power Design Engineer – Data Center Accelerator Boards

The Role: We are looking for a Power Design Engineer to own the power delivery architecture and implementation for our accelerator PCBs used in data center servers for HPC and AI/ML workloads. You will be responsible for high‑current, high‑efficiency VRM design, power tree definition, and ensuring robust power integrity for advanced accelerator SoCs and high‑speed memory. Responsibilities: · Architect and design the power supply and board-level power delivery network (PDN) for accelerator cards and related platforms: o Define power trees, rails, sequencing, and margining o Select VRMs, DC‑DC converters, controllers, FETs, magnetics, and protection components o Investigate PCB technology options and define power delivery strategies for high-current, low-voltage environments · Enable the supply chain and work with suppliers over the full lifecycle · Perform schematic design for power stages and collaborate with layout engineers to ensure proper placement, routing, and copper utilization for high‑current paths. · Work closely with PI/SI engineers on PDN impedance, decoupling strategies, and transient performance. · Specify and guide power-on sequencing, monitoring, and telemetry (PMBus, I2C, etc.). · Conduct lab validation of power subsystems: o Efficiency, ripple, transient response, stability o Load/line regulation and thermal performance · Lead debug of power-related issues (e.g., startup failures, droop, noise coupling, OCP/OVP events). · Collaborate with silicon, hardware, system, reliability, and manufacturing teams to ensure design-for-reliability (DFR) and design-for-manufacturability (DFM) of power solutions. · Generate design documentation, test plans, and bring‑up procedures. Required Qualifications: · Bachelor’s and Master’s degree in Electrical Engineering or related field. · 5+ years of experience in board-level power design for high‑performance or server‑class systems. · Strong understanding of: o Switching power converters (buck, multiphase, POL regulators) o Power topologies, compensation, and stability o High‑current layout techniques and loss optimization · Hands‑on experience with schematic capture (e.g., Siemens Xpedition) and familiarity with PCB layout constraint definition. · Proficiency with lab equipment (oscilloscopes, electronic loads, power analyzers, DMMs). Preferred Qualifications: · Experience designing power delivery for GPUs, CPUs, FPGAs, or custom accelerators in data center environments. · Familiarity with PI simulation concepts and tools (e.g., CADENCE PowerSI, PowerDC, OptimizePI, VRM simulation (SIMetrix/SIMPLIS), etc.). · Working knowledge of server power standards, hot‑plug, derating, and redundancy considerations. · Relevant experience in Long-Term Reliability prediction and testing (e.g., MTBF, FMEA, FIT, HTOL/HAST). · Compliance, Certification and Regulatory requirements knowledge for Power Delivery Designs and Qualification. · Experience with PMBus configuration and debugging. · Basic scripting skills for test automation (Python, LabVIEW, etc.). What do we offer? · Join an innovative team and experience company growth. · We believe in investing in our employees and providing them with the opportunities they need to grow and develop their careers. · Enjoy a hybrid work environment. · We also offer flexible schedule. · We offer a remuneration that values your experience. · The position will have preferably the base in Karlsruhe (Germany). We are looking for outstanding people willing to join our mission to change this industry and help to build a better world. If you feel identified with Openchip, please contact us. We can offer a competitive compensation package in a flexible work schema that will help you to keep a balance between your personal and professional life. At Openchip & Software Technologies S.L., we believe a diverse and inclusive team is the key to groundbreaking ideas. We foster a work environment where everyone feels valued, respected, and empowered to reach their full potential – regardless of race, gender, ethnicity, sexual orientation, or gender identity.
