Power Electronics Engineer

GridBlock is an innovative energy router that dynamically manages the flow of energy between multiple sources and loads and has the ability to create and operate a self-contained microgrid. GridBlock packetizes and routes electrical energy with isolation and high accuracy to serve AC or DC systems seamlessly. The precision technology enables a bidirectional power flow on multiple ports or channels concurrently, bringing the flexibility and control of Internet routers and switches to the electrical grid. Increasingly, electrical installations require smart integration of EV or e-truck charging, battery storage, solar panels, and critical loads, with custom design and build for each location adding to the cost of implementation. GridBlock simplifies all of this with a flexible, software-defined, modular solution that can manage a wide variety of end‑use configurations and applications, from 500kW to 100+ MW deployments. GridBlock has an exciting opportunity for a Power Electronics Engineer. In this position, you will work directly with the research & development to support the design of cutting‑edge power electronics products, as well as set up a consistent, reliable, and efficient test environment for GridBlock’s power electronics product suite.
