Principal Power Design Engineer

About the role

We are seeking a Principal Power Design Engineer to own the design, implementation, and validation of the power delivery systems that support our high-performance AI compute hardware.

AI compute systems create extreme, high-frequency transient current steps that can destabilize hardware, introduce power supply noise, and corrupt sensitive high-speed data links. In this role, you will be responsible for component selection, schematic design, layout oversight, and hands-on lab validation of high-current power subsystems. You will design and test multi-phase voltage regulators, point-of-load converters, and sequencing circuitry to ensure our systems remain stable under demanding, dynamic AI inference workloads.

Key Responsibilities

• Own hardware schematic design for multi-phase buck regulators, point-of-load converters, and power sequencing circuitry.
• Select critical power components, including passives, inductors, power stages, controllers, and supporting circuitry.
• Define placement and routing constraints for board-level power delivery networks, including decoupling capacitor strategy and high-current power paths.
• Work closely with package engineering to ensure clean power delivery handoff at the socket or package interface.
• Lead lab validation of power subsystems, including VRM efficiency, loop stability, DC IR drop, thermal behavior, and transient response.
• Use oscilloscopes, electronic loads, network analyzers, thermal cameras, and related lab equipment to characterize power rails under maximum dynamic load conditions.
• Partner with SI/PI engineers to measure and mitigate power supply noise and Power Supply Induced Jitter on sensitive high-speed lanes.
• Debug power integrity issues across board, package, silicon, firmware, workload, and system-level interactions.
• Contribute to design guidelines, validation plans, and best practices for power delivery across the company’s hardware platforms.

Required Skills and Qualifications

• Extensive experience designing high-current, multi-phase DC-DC regulators for high-power ASICs, GPUs, processors, accelerators, or similar compute platforms.
• Strong background in power hardware design for systems with 500W+ devices or comparable high-current power delivery requirements.
• Deep understanding of board-level PDN implementation, decoupling strategy, power sequencing, transient response, and voltage regulation.
• Hands-on experience with schematic capture and layout oversight for complex power delivery systems, preferably using tools such as Cadence Allegro or Concept.
• Strong lab validation skills using electronic loads, oscilloscopes, network analyzers for loop stability testing, thermal cameras, and related power measurement equipment.
• Experience characterizing VRM efficiency, bode plots, DC IR drop, ripple, noise, and transient behavior under dynamic workloads.
• Proficiency with SPICE-based time-domain circuit simulation or similar power simulation workflows.
• Ability to collaborate closely with SI/PI, package, hardware, firmware, and systems teams in a fast-moving engineering environment.

Desired Skills

• Experience with power delivery for AI accelerators, GPUs, networking ASICs, switch ASICs, or high-performance server platforms.
• Familiarity with power integrity interactions affecting high-speed SerDes, PCIe, Ethernet, CXL, or other sensitive interfaces.
• Experience validating power systems under real workload conditions, including dynamic AI inference or high-utilization compute workloads.
• Exposure to package-level power delivery, socket interfaces, or advanced board/package co-design.
• Experience developing automated lab validation flows using Python or similar scripting languages.

Compensation

Target base salary for this role is $160,000 - $240,000 CAD per year + meaningful equity + benefits + 401k. Our salary ranges are determined by role, level, experience, and location.
