Join the Consolidated Team!

Consolidated Sterilizer Systems has manufactured state-of-the-art, custom steam sterilizers (autoclaves) for clients in the life sciences and healthcare industries since 1946.

You can find our autoclaves in all the top research laboratories, universities, and biotech companies around the US, where they’re used for everything from medical device creation and cancer research to mushroom cultivation and cannabis micropropagation. All of our autoclaves are manufactured in Billerica, MA and marketed and sold to customers in over 70 countries through a network of qualified distributors and knowledgeable manufacturer sales representatives.

It’s our mission to provide the most reliable, affordable, and customizable sterilization systems on the market today, all while offering the best customer experience in sales and service. None of this would be possible without our amazing team — which we’re always looking for talented, motivated people to join.

If that sounds like you, check out our list of available openings; if you don’t see any current listings, we encourage you to reach out to us directly.

“One thing I really love about the culture [is that] we’re all from different backgrounds and all have different roles, but we all want to learn. There are so many knowledgeable people at CSS that it makes you want to be better… That’s something that’s really unique.”

— Monica Johnstone, Accounts Receivable

Everybody here definitely works hard and goes above and beyond to exceed production demands, but there’s also such a friendly atmosphere and relaxed feeling. You feel accepted for who you are and comfortable in your own skin, which enables you to shine a bit.”
