GridBlock has an exciting opportunity for an Electrical Engineering Intern to join our Summer Internship Program. If you’re passionate about sustainability and want hands-on experience building next-generation power conversion hardware, this internship may be a great fit.

As an Electrical Engineering Intern, you’ll be part of our Research & Development team working on GridBlock’s soft switching solid-state transformer platform and advanced power electronics technologies. You’ll help bring up and validate SMPS, run lab testing across operating conditions, debug issues, and iterate designs to improve performance, reliability, and manufacturability. If you’re excited by soft-switching, multiport power conversion, and the challenge of building real hardware that enables modern electrification and resilient infrastructure—come build it with us.

Key responsibilities include but are not limited to:

• Debug hardware/firmware issues using lab equipment (oscilloscope, power analyzer, electronic loads, DMM, current probes), identify root cause, and propose/implement design fixes.
• PCB Design: Schematic capture and PCB layout (Cadence preferred)
• Maintain clear documentation of test results, design issues, corrective actions, and design changes for future builds and knowledge transfer.
• Execute bench validation across operating conditions (line/load transients, thermal sweeps, efficiency mapping, fault scenarios), and evaluate stability, performance, and robustness.

Skills & Requirements

Education / Experience

• Bachelor’s or Master’s degree in Electrical Engineering or a related field.

Specific Skills / Abilities

• Strong knowledge of digital and analog circuit analysis.
• Understanding of power semiconductor devices (MOSFET/IGBT/SiC/GaN), gate driving, and protection (UVLO/OCP/OVP/OTP).
• Understanding of switched mode power supplies.
• Ability to interpret datasheets, select components, and evaluate derating, thermal limits, and reliability considerations.
• Strong skills with electrical test equipment including oscilloscopes, multimeters, function generators, and bench power supplies.
• Experience debugging electronics and modifying PCBs.
• Experience creating and following test plans.
• Experience programming embedded systems in C.

About GridBlock

GridBlock is an innovative energy router that dynamically manages the flow of energy between multiple sources and loads and is able 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.

GridBlock is part of Endeavour, a purpose-built company taking on global challenges to guarantee renewable energy and clean water to everyone, everywhere by decentralizing infrastructure, developing new technologies, and deploying energy, water, and waste valorization solutions that are more profitable than those that currently exist. Endeavour companies are made up of passionate change-makers who want to leave the world better than the way we found it.
