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 control loop design and validation 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 validation.  Support other power related projects as needed. 
• Develop prototype firmware for hardware bring up and testing while working with our established firmware team to transition these efforts into production.
• Design and test controls code in high voltage and high power set ups and validate its functionality and performance.
• Collaborate with firmware, electrical, mechanical, manufacturing and other engineers as needed.
• Support the transition from new product development into high volume manufacturing.  Assist in developing production line testing of the systems you developed when needed.
• Work closely with a team of passionate engineers to ensure we develop exceptional hardware products – participate and/or lead design reviews and trades as needed, or lend a hand with testing and debug as required.  We are a small team requiring a high level of collaboration and teamwork to ensure we achieve our goals.

Required Qualifications & Skills 

• 10+ years experience developing complex products as a power electronics controls engineer, electrical engineer, or related role. 

• 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. 

• Experience with modeling and simulation-aided analysis for control loop design in tools such as PLECS. 

• Strong understanding of power converter theory and design 

• Working knowledge of renewable energy related concepts such as home energy storage systems, general power conversion/regulation/distribution, and power fault protection 

• Familiar with scripting language such as Python, Javascript, Visual Basic, or equivalent 

• Electrical hardware lab equipment familiarity 

• Demonstrated experience managing workload and project deliverables 

• Strong writing, interpersonal, and communication skills 

Desired Qualifications & Skills 

• MS/PhD in electrical engineering or related field 

• Bidirectional inverter design experience for North American grid tied applications 

• Experience writing embedded software for the STM32 family of microcontrollers 

• Experience designing and debugging for electrical and safety compliance standards such as FCC, CE, UL/ETL, etc. 

• Experience designing and shipping high-volume consumer products
