Senior Staff Platform Power Delivery Network Engineer

Mission: End-to-end power delivery network design of Groqs next-gen platform to enable state-of-the-art AI/ML workloads and guide future hardware development of the most advanced AI accelerator on the market.

Responsibilities & opportunities in this role:

• Full-Stack Power Delivery Design
• Design state-of-the-art multi-stage power delivery network (>48V intermediate bus architectures POL regulators on-package IVRs).
• Model and optimize impedance from bulk VRMs (Voltage Regulator Modules) to die-level power rails including PCB planes interposers and TSVs.
• Implement adaptive voltage scaling (AVS) and dynamic current balancing for load-agnostic efficiency.
• Cross-Functional Collaboration
• Work closely with system lead engineers and power integrity engineers to minimize PDN impedance through plane-pair optimization via stitching and low-ESL decoupling strategies.
• Guide silicon and packaging teams on integrating embedded regulators (e.g. FIVRs) and on-die capacitance for GHz-frequency transient response.
• Work with platform and datacenter architects to define power budgets and redundancy schemes for >48V-to-1V conversion chains.
• Simulation & Validation
• Support power integrity checks using AC/DC analysis load-step time-domain simulations in SPICE to meet target impedance.
• Validate PDN using Bode plots loop stability and impedance measurements with vector network analyzer (VNA)
• Characterize system efficiency using precision power analyzers and thermal chambers.
• TCO & Efficiency Optimization
• Reduce IR losses through copper weight optimization and low-resistance interconnect materials.
• Investigate deployment of advanced topologies: vertical power delivery networks multi-phase interleaved buck converters GaN-based VRMs and high-voltage busbars.
• Analyze trade-offs between different power distribution architectures for hyperscale systems deployed in the datacenter.
• Work closely with industry partners and vendors to identify cost-effective and energy-efficient solutions for Groqs current and future platforms

Apply if you can:

• Can articulate trade-offs between LLC resonant converters vs. buck-derived topologies for VRMs.
• Have debugged ground loops causing efficiency loss in multi-board systems.
• Understand how PDN Ztarget V / I relates to load-step scenarios

Ideal candidates have/are:

• Degree in electrical engineering power electronics semiconductor device physics or a related discipline
• Hands-on experience constructing testing and delivering PDN designs for high-load current and high-load step applications involving multi-stage voltage conversion
• Hands-on testing experience of VRM Bode plots loop stability analysis and PDN impedance measurements
• Substantial background in analog circuit design emphasizing switched-mode power converters and linear power regulators
• Experience utilizing switched mode circuit design and simulation tools such as SIMPLIS and LTSpice is a plus
• Experience with high-voltage direct-to-chip architectures and knowledge of wide-bandgap semiconductors (SiC GaN) for high-frequency VRMs is a plus
• Experience with AI/ML workload power profiling and adaptive PDN tuning 3D IC packaging (EMIB CoWoS) and silicon interposer PDNs
• Exceptional teamwork communication and documentation skills
• The ability to learn new concepts rapidly comprehensively and independently
• A high degree of self-motivation and personal accountability
• The ability to work effectively in a fast-paced environment with significant time constraints

Attributes of a Groqster:

• Humility - Egos are checked at the door
• Collaborative & Team Savvy - We make up the smartest person in the room together
• Growth & Giver Mindset - Learn it all versus know it all we share knowledge generously
• Curious & Innovative - Take a creative approach to projects problems and design
• Passion Grit & Boldness - no limit thinking fueling informed risk taking
