Hardware Systems Engineer – Power Electronics

Summary

Designs and develops high-current power distribution and interconnect hardware for AI servers, EVs, and aerospace systems, collaborating with OEMs and hyperscalers.

CelLink's ultra-thin flexible interconnect technology is redefining how power is delivered inside the world's most advanced AI, hyperscale, and high-performance computing platforms.
As a Hardware Systems Engineer, you will design and develop the rack-level power hardware that enables next-generation server architectures. You will own electrical hardware from concept through production, developing high-current power distribution solutions that integrate seamlessly into hyperscale server racks.
This role combines electrical hardware design, system architecture, and hands-on engineering. You'll work directly with hyperscalers, OEMs, ASIC vendors, and internal cross-functional teams to develop reliable, manufacturable, and scalable power delivery solutions that support the rapidly evolving demands of AI infrastructure.

Essential Duties and Responsibilities

  • Design and develop rack-level power distribution hardware for AI, HPC, and hyperscale server platforms.
    Own electrical hardware throughout the product lifecycle, from concept, prototyping, validation, and production release.
  • Define electrical architecture for rack-level power delivery systems, balancing electrical performance, thermal requirements, mechanical integration, manufacturability, and reliability.
  • Perform first-order electrical engineering calculations including current carrying capacity, voltage drop, resistance, inductance, thermal performance, and power loss.
  • Own and launch designs into low and high-volume production.
  • Work directly with hyperscalers and OEMs to understand system requirements and translate them into robust hardware designs.
  • Create engineering documentation including electrical schematics, CAD models, engineering drawings, BOMs, tolerance analyses, and design reports.
  • Present technical solutions to customers and internal engineering teams while serving as the technical expert for rack-level power hardware.
  • Willingness to travel up to 20%.

Minimum Qualifications (Knowledge, Skills, and Abilities)

  • Bachelor's or Master's degree in Electrical Engineering or closely related discipline.
  • 3+ years of experience designing electrical hardware for server, networking, storage, AI, or power electronics applications.
  • Experience owning electrical hardware designs from concept through production.
  • Strong understanding of rack-level power distribution, power delivery architecture, or high-current electrical systems.
  • Experience performing electrical engineering calculations supporting hardware design decisions.
  • Working knowledge of Design for Manufacturing (DFM) principles and manufacturing release processes.
  • Experience collaborating with mechanical engineering on electrical hardware packaging and integration.
  • Ability to communicate technical concepts clearly with customers, suppliers, and cross-functional engineering teams.

Bonus Points

  • Familiarity with SolidWorks, Creo, Siemens NX, or similar mechanical CAD tools for electrical hardware integration.
  • Understanding of Power Integrity (PI), Signal Integrity (SI), and thermal considerations for high-performance computing systems.
  • Experience supporting hardware validation, EVT, DVT, and production qualification.
  • Knowledge of flexible printed circuits (FPC), busbar technologies, laminated interconnects, or custom power distribution assemblies.

Base Salary

  • Final salary determined by experience and level. We’re hiring for multiple positions and will align compensation accordingly.

Working Conditions/Hours

  • Salaried Exempt
  • 100% onsite
