About The Position

Emporia is a leading technology company revolutionizing home energy by providing affordable, integrated solutions that empower homeowners to optimize energy usage to reduce costs and carbon footprint. Emporia’s Home Energy Management Platform is a powerful software system that connects their Vue Home Energy Monitor, Level 2 EV Charger, Smart Plugs, Home Battery, and third-party thermostats and appliances. By automating energy use through real-time monitoring and scheduling, the platform optimizes consumption, reduces costs, and simplifies home energy management—all within one intuitive app. With over 400,000 U.S. homes running Emporia’s energy management and EV charging hardware, we are now launching a national Third-Party Owned (TPO) home battery Virtual Power Plant — placing industrial-rated home batteries in residential homes to deliver power redundancy, utility cost savings, and grid peak demand services. By reducing energy waste and saving customers money, we’re helping create a healthier planet and a brighter future. For more information, visit emporiaenergy.com. Our Hardware Engineering team is seeking a Test Engineer to conduct hardware testing across our EVSE product line and new products in development, while also contributing to sustaining engineering activities. The ideal candidate brings experience in all phases of hardware test; from requirements tracking and test plan development through fixture design, in-house and out-of-house test execution, combined with hands-on sustaining engineering skills including field failure investigation, root cause analysis, and minor PCBA design changes. This role will partner closely with external test labs, contract manufacturers, automotive OEM customers, and internal firmware, electrical and mechanical teams. Experience with high-power AC and DC electrical systems and custom PCBA design is desired but an eagerness to learn and adapt in a fast-paced environment is required. We are a small, collaborative team where versatility and ownership are highly valued.
