Role Overview

At Emporia Energy, hardware products are the tip of the spear - attracting customers, fueling data analytics, and enabling demand response through integration with Emporia’s energy management platform. We provide our customers with reliable, high value-add products at industry-leading pricing.

We are looking for a passionate Power Electronics Controls Engineer to help expand the Emporia Energy hardware ecosystem – initially by working on our upcoming Bidirectional EV Charger. Work will involve owning control loop design and verification for both AC/DC and DC/DC power converters and contributing to needed V2G, G2V, and V2H control designs. As a senior member of the Hardware Development team, the ideal candidate will be expected to work closely with and provide mentorship to peers and junior members of the team, as needed for this cross disciplinary project.

Throughout, they will demonstrate the strong analysis, design, and test skills required to produce the reliable, low-cost hardware that our customers expect.

Responsibilities

• Own the design and validation of the control loop for bidirectional AC/DC and DC/DC power conversion hardware, including units involving the interconnection of multiple converters acting together as a single product
• Act as a technical expert for bidirectional 10 kW+ level AC/DC and DC/DC control systems at all stages of design and verification. Support other power related projects as needed
• Design controls code for high voltage and high power systems and validate its functionality and performance
• Work with our established firmware team to transition that code into production
• Develop prototype firmware to enable hardware bring up and testing
• Support the transition from new product development into high volume manufacturing including assisting with the development of production line testing methods
• Lead and/or participate in design reviews and trade studies as needed
• Collaborate with firmware, electrical, mechanical, manufacturing and other engineering teams

Required Qualifications & Skills

• Bachelor's degree in Electrical Engineering or related field
• 10+ years experience developing complex products as a power electronics controls engineer, electrical engineer, or related role
• Strong understanding of power converter theory and design
• Experience developing digital control systems for grid tied inverters, rectifiers, and DC/DC converters using microcontroller platforms
• Working knowledge of V2G and G2V related regulations in North America as they relate to the design of grid interactive power converters
• Working knowledge of renewable energy related concepts such as home energy storage systems, general power conversion/regulation/distribution, and power fault protection
• Experience with modeling and simulation-aided analysis for control loop design in tools such as…
