  • Internship

    We are proud to have a lot of knowledge and tools all in one place, like classroom, lab, and test areas. We think that internships are a great way to learn practical things, even while you’re still in school. Right now, we have two types:

    • Summer Internship: This is good if you want to do something useful when you’re not in school. Our experts in heat & power and water treatment will teach you practical stuff that you can use in the real world. With time, you’ll be able to solve problems on your own.
    • Project Internship: If you’re working on your final school project, this one’s for you. We’ll help guide you without doing the work for you. The main goal is to help you think on your own when dealing with engineering problems and stick to your school’s way of doing things.

    If any of this sounds interesting, please reach out to us.

    We'd love to hear from you!
