GridBlock has an exciting opportunity for an Electrical Engineering Intern to take part in our Summer Internship Program. If you’re passionate about sustainability and eager to be part of a company that’s on a journey to transform the world’s infrastructure, this may be the internship for you!

The Electrical Engineering Intern is a vital member of Endeavour’s GridBlock team and will be part of the research & development group to test, debug, and revise critical electronic components in GridBlock’s controller module. You will be responsible for bringing up a supercapacitor-based uninterruptable power supply (UPS) and an industrial LED driver, testing different operating conditions, identifying faults, and revising the designs to fix them.

• Test and revise a supercapacitor UPS
        - Write firmware in C to communicate with and control a UPS board.
        - Test the UPS under various operating conditions, evaluate thermal performance, and ensure stable operation.
        - Identify problems in hardware and revise the design to improve them.

• Test and revise an industrial LED driver
        - Test the LED driver under different load conditions.
       - Determine optimal current and PWM setpoints for thermal performance and power consumption.
        - Identify problems in hardware and revise the design to improve them.

• Document design problems and hardware changes for future reference

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

• Strong knowledge of digital and analog circuit analysis.
• Understanding of switched mode power supplies, specifically 4-switch buck-boost and SEPIC topologies.
• Experience with digital communication protocols including I2C and SPI.
• 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.

Endeavour is taking on global challenges, and to create the appropriate global solutions is not easy. Our teams work extremely hard because we believe in Endeavour’s mission: to guarantee clean water and renewable energy to everyone, everywhere by decentralizing infrastructure, developing new technologies, & deploying energy, water, and waste treatment solutions that are more profitable than those that currently exist. We are a group of passionate change-makers who want to leave the world better than the way we found it. Endeavour prides itself on hiring talented, highly motivated people because that’s what our mission requires. There is a strong sense of camaraderie between good-natured people who bring their A-game to work every day to make a difference. To work at Endeavour is to know that you are part of something special—something bigger than yourself.

Today, we’re deploying solutions that are immediately scalable and profitable, including EV charging, data center cooling, and waste to fuel systems. As we look to the future, Endeavour intends to remain at the forefront of innovation, taking on grander challenges based on the needs of our clients and of local economies. We hope that our Sustainable Habitat for Innovation with a Purpose (SHIP) will be a model that inspires people and businesses to #jointhejourney so that together we can combine the best of what technology and the natural world can offer to ensure a regenerative/sustainable world for generations to come.
