Contract Power Electronics Engineer information

What is the difference between Contract Power Electronics Engineer vs Contract Electrical Engineer?

AspectContract Power Electronics EngineerContract Electrical Engineer
CredentialsBachelor's or Master's in Electrical Engineering, specialized in power electronicsBachelor's or Master's in Electrical Engineering, broader focus on electrical systems
Work EnvironmentDesign, develop, and test power electronic systems in labs or client sitesWork on electrical systems, wiring, and power distribution in various industries
Industry UsagePower electronics, renewable energy, industrial automationConstruction, manufacturing, utilities, and general electrical projects

Contract Power Electronics Engineers focus on designing and testing power electronic systems, while Contract Electrical Engineers handle broader electrical systems. Both roles require electrical engineering credentials but differ in specialization and industry applications.

What are the key skills and qualifications needed to thrive as a contract power electronics engineer?

To thrive as a Contract Power Electronics Engineer, you need a solid background in electrical engineering, circuit design, and experience with power conversion systems, usually supported by a relevant engineering degree. Familiarity with simulation tools like SPICE, PCB design software such as Altium Designer, and industry certifications like Professional Engineer (PE) are highly valued. Strong problem-solving abilities, effective communication, and adaptability help contractors quickly integrate with new teams and tackle diverse projects. These skills ensure efficient project delivery, technical excellence, and successful client relationships in a fast-paced, project-driven environment.

What is a contract power electronics engineer?

A Contract Power Electronics Engineer is a specialized professional hired on a temporary basis to design, develop, and test electronic systems and devices that control and convert electric power. These engineers typically work on projects involving power converters, inverters, and motor drives for industries such as automotive, renewable energy, and industrial automation. Contract roles may involve collaborating with clients, troubleshooting issues, and ensuring that solutions meet project specifications and safety standards. Unlike permanent employees, contract engineers are usually engaged for specific projects or time frames and may work independently or as part of a team.

What are some common challenges contract power electronics engineers face when working with diverse clients and projects?

Contract Power Electronics Engineers often work with a variety of clients, each with unique requirements, timelines, and technical standards. Adapting quickly to new project scopes and understanding different system architectures can be challenging. Additionally, balancing multiple projects and ensuring clear communication between cross-functional teams—such as hardware, software, and manufacturing—requires strong organizational and interpersonal skills. Staying updated with the latest industry trends and compliance standards is also crucial for success in contract roles.

Job description

Medium Voltage Power Conversion

Location: Sullivan, MO / Orange County, CA

Path: Full-Time

Infinity Miles is seeking a Senior Power Electronics Engineer to lead the design and development of advanced medium-voltage power conversion systems for commercial deployment. We are developing next-generation medium-voltage Solid-State Transformer (SST) technology for AI data centers, renewable energy systems, battery energy storage, EV charging infrastructure, and grid modernization.

Position Overview

The Senior/Principal Power Electronics Engineer will be responsible for the architecture, design, analysis, testing, and validation of high-power converter systems. This role will drive the development of next-generation power conversion hardware from concept through commercialization.

Preferred Qualifications
  • M.S. or Ph.D. in Electrical Engineering, Power Electronics, or related field
  • 5+ years of industry experience in power electronics design and development
  • Strong understanding of high-power converter topologies and control principles
  • Experience with SiC-based power conversion systems
  • Experience designing converters in the tens of kilowatts to multi-megawatt range
  • Familiarity with medium-voltage systems and insulation requirements
  • Knowledge of thermal management, EMI/EMC, electrical safety, and reliability considerations
  • Hands-on experience with laboratory testing, debugging, and prototype validation
  • Familiarity with UL, IEC, IEEE, and grid-interconnection standards
Responsibilities
  • Design and develop high-power isolated and non-isolated converter systems
  • Develop advanced converter topologies including Cascaded H-Bridge, Multi-Level Converters, Dual Active Bridge (DAB), Resonant Converters, and related architectures
  • Design power stages utilizing SiC devices and advanced gate drive technologies
  • Perform system-level trade studies balancing efficiency, power density, thermal performance, reliability, manufacturability, and cost
  • Develop converter protection strategies including fault detection, isolation, and system safety functions
  • Perform simulation and analysis using PLECS, LTspice, MATLAB/Simulink, PSIM, or equivalent tools
  • Lead laboratory testing, troubleshooting, and performance validation of prototype systems
  • Collaborate with controls, magnetics, mechanical, manufacturing, and test engineering teams
  • Mentor junior engineers and provide technical leadership within the organization

Help commercialize one of the industry's most advanced Solid-State Transformer platforms with significant technical leadership and career growth opportunities.
