Our Culture

Critical Manufacturing of Equipment for Submarines

Granite State Manufacturing (GSM) is family owned and locally based. And while we don’t have thousands of employees like the “big guys,” there’s nothing small about our work. For more than 80 years, we have served some of the world’s top companies in defense, aerospace, homeland security, and other vital industries.

Tools: Beyond State-of-the-Art

Here, you’ll be challenged to find solutions to complex manufacturing problems, and you’ll do it with the latest and greatest machines and technology. In fact, you’ll have the chance to hone your skills with state-of-the-art equipment you won’t find in your father’s machine shop.

Advancement: Not Just a Buzzword

We believe in rewarding achievement because we do well when you do well. Promotions are based on performance, not seniority, so when you excel, you’re rewarded—it’s that simple. At GSM, advancement is more than a possibility; it’s a reality.
