Power Design Engineer – Data Center Accelerator Boards

<p><strong>The Role:</strong></p>
<p>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.</p>
<p><strong>Responsibilities</strong>:</p>
<p>· Architect and design the power supply and board-level power delivery network (PDN) for accelerator cards and related platforms:</p>
<p>o Define power trees, rails, sequencing, and margining</p>
<p>o Select VRMs, DC‑DC converters, controllers, FETs, magnetics, and protection components</p>
<p>o Investigate PCB technology options and define power delivery strategies for high-current, low-voltage environments</p>
<p>· Enable the supply chain and work with suppliers over the full lifecycle</p>
<p>· Perform schematic design for power stages and collaborate with layout engineers to ensure proper placement, routing, and copper utilization for high‑current paths.</p>
<p>· Work closely with PI/SI engineers on PDN impedance, decoupling strategies, and transient performance.</p>
<p>· Specify and guide power-on sequencing, monitoring, and telemetry (PMBus, I2C, etc.).</p>
<p>· Conduct lab validation of power subsystems:</p>
<p>o Efficiency, ripple, transient response, stability</p>
<p>o Load/line regulation and thermal performance</p>
<p>· Lead debug of power-related issues (e.g., startup failures, droop, noise coupling, OCP/OVP events).</p>
<p>· Collaborate with silicon, hardware, system, reliability, and manufacturing teams to ensure design-for-reliability (DFR) and design-for-manufacturability (DFM) of power solutions.</p>
<p>· Generate design documentation, test plans, and bring‑up procedures.</p>
<p><strong>Required Qualifications:</strong></p>
<p>· Bachelor’s and Master’s degree in Electrical Engineering or related field.</p>
<p>· 5+ years of experience in board-level power design for high‑performance or server‑class systems.</p>
<p>· Strong understanding of:</p>
<p>o Switching power converters (buck, multiphase, POL regulators)</p>
<p>o Power topologies, compensation, and stability</p>
<p>o High‑current layout techniques and loss optimization</p>
<p>· Hands‑on experience with schematic capture (e.g., Siemens Xpedition) and familiarity with PCB layout constraint definition.</p>
<p>· Proficiency with lab equipment (oscilloscopes, electronic loads, power analyzers, DMMs).</p>
<p><strong>Preferred Qualifications:</strong></p>
<p>· Experience designing power delivery for GPUs, CPUs, FPGAs, or custom accelerators in data center environments.</p>
<p>· Familiarity with PI simulation concepts and tools (e.g., CADENCE PowerSI, PowerDC, OptimizePI, VRM simulation (SIMetrix/SIMPLIS), etc.).</p>
<p>· Working knowledge of server power standards, hot‑plug, derating, and redundancy considerations.</p>
<p>· Relevant experience in Long-Term Reliability prediction and testing (e.g., MTBF, FMEA, FIT, HTOL/HAST).</p>
<p>· Compliance, Certification and Regulatory requirements knowledge for Power Delivery Designs and Qualification.</p>
<p>· Experience with PMBus configuration and debugging.</p>
<p>· Basic scripting skills for test automation (Python, LabVIEW, etc.).</p>
<p><strong>What do we offer?</strong></p>
<p>· Join an innovative team and experience company growth.</p>
<p>· We believe in investing in our employees and providing them with the opportunities they need to grow and develop their careers.</p>
<p>· Enjoy a hybrid work environment.</p>
<p>· We also offer flexible schedule.</p>
<p>· We offer a remuneration that values your experience.</p>
<p>· The position will have preferably the base in Karlsruhe (Germany).</p>
<p>We are looking for <strong>outstanding</strong> people willing to join our mission to change this industry and help to build a better world.</p>
