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 products at industry-leading prices.

We are looking for a passionate Senior Power Electronics Engineer to help expand the Emporia Energy hardware ecosystem – initially by working on our upcoming Bidirectional EV Charger. The role involves owning control loop design and verification for AC/DC and DC/DC power converters and contributing to V2G, G2V, and V2H hardware and control designs. As a senior member of the Hardware Development team, the candidate will work closely with peers on this cross-disciplinary project, providing mentorship to mid and junior engineers, and demonstrating strong analysis, design, and testing skills to produce reliable, low-cost hardware.

Responsibilities

• Act as the primary technical expert for bidirectional 10 kW+ level AC/DC and DC/DC power electronics hardware and control systems at all design and validation stages.
• Provide power electronics hardware expertise to lower-level engineers, especially for a bidirectional dual-active bridge architecture.
• Support other power-related projects as needed.
• Understand control loop design and operation for bidirectional power converters.
• Collaborate with controls and firmware teams to mature and transition designs into production.
• Work with mechanical, manufacturing, and electrical engineers as needed.
• Support transition from development to high-volume manufacturing.
• Assist in developing production line testing for developed systems.
• Participate in design reviews, testing, and debugging, fostering collaboration within the small team.

Required Qualifications & Skills

• BSc in Electrical Engineering or related field.
• 10+ years of experience in power electronics development for commercial products.
• Experience with digital control systems for grid-tied inverters, rectifiers, and DC/DC converters using microcontroller platforms.
• Hardware development experience including topology selection, switching devices, magnetics, and sensing networks.
• Understanding of simulation-aided control loop analysis.
• Strong knowledge of power converter theory and design.
• Proficiency in scripting languages such as Python and C.
• Familiarity with electrical hardware lab equipment.
• Experience managing workload and project timelines.
• Excellent communication and interpersonal skills.

Desired Qualifications & Skills

• MS or PhD in Electrical Engineering or related field.
• Knowledge of V2G and G2V regulations in North America related to grid-interactive power converters.
• Bidirectional inverter design experience for North American grid applications.
• Understanding of renewable energy concepts, including home energy storage, power conversion, and fault protection.
• Experience programming embedded software for STM32 microcontrollers.
• Experience with electrical and safety compliance standards (FCC, CE, UL/ETL).
• Experience in designing and shipping high-volume consumer products.

What We Offer
Compensation: $140k-180k + Options
Career Growth: Join a fast-growing company leading in home energy innovation.
