Company Summary

Company Reviews

Subzero ensures a superior customer experience by applying unique product designs, quick turnaround
engineering, and in-house installation teams.

Founded in 2005 by Larry Mainers and Vince Lake, Subzero started out as a data center airflow consulting company utilizing CFD studies to provide layout and design recommendations. The next decade would see them develop and release numerous industry changing products that would define how data center containment could and would be done. With the addition of server cabinets, PDUs, cages, and hyper scale specialty offerings, Subzero has cemented itself as a go to partner in a growing industry.

Our Sales Engineers will be working closely with your Data Center Solutions Manager to ensure a successful and enjoyable experience. All products have been built to scale inside of SolidWorks, which allows for quick turnaround on mechanical drawings. A typical proposal and drawing set can be provided in as little as 24 hours, and never more than 72.

From its inception, Subzero’s offerings have always been about three things:

CUSTOMIZATION
Data centers are varied and dynamic, the solutions that go inside them should be too. Subzero’s entire line of products are all completely customizable allowing the ability to quickly design, ship, and install.

QUALITY
A culture of best-in-class has been a part of Subzero from the beginning. From the raw materials used, to the components sourced, this self-imposed standard ensures that a great design becomes an even greater product.

FIT AND FINISH
Flexibility and quality are important, but it needs to look good too. High precision machining combined with thoughtfulness in design guarantees a great looking product. Highly trained and experienced site service teams ensure each project is deployed to meet the quality standards above.

Thanks for taking the time to consider us, and we look forward to working with you.

Field Service Engineer
3.0

Okay for now, but growth stalls eventually.
Pros: You get solid hands-on experience with data center cooling systems. It's great for learning the industry ropes. They'll even pay for some initial certifications if you push for it.
Cons: Career growth feels pretty limited past the entry to mid-level as a Field Service Engineer. There's not much of a clear path for advancement or internal promotions. It feels like you hit a ceiling pretty fast here.
Advice to Management: Create clearer career progression paths for your Field Service Engineers. Invest more in ongoing professional development and internal leadership training. This would really help with retention in the data center cooling sector.

Okay stability, but watch out for project shifts
Pros: There's usually plenty of work, especially with all the new `data center` build-outs. As an `installation specialist`, I felt pretty secure; they really need people on these `containment solutions`.
Cons: Project cycles can be tough though. Sometimes work slows down, and hours get cut, which isn't great for consistent income. Pay raises are also kinda slow for `onsite` roles.
Advice to Management: Try to smooth out the project load better to ensure more consistent hours for `field technicians`. Better communication around slow periods would help a lot.

Culture is Okay, But Needs Consistency
Pros: I've learned a ton about data center cooling and airflow management here. People are generally supportive, which is a big plus for Project Engineer roles. It's a solid place if you're working onsite and want to learn.
Cons: The company culture feels a bit inconsistent. Sometimes there's a lot of pressure, making it tough to maintain good work-life balance. Leadership communication can be unclear at times.
Advice to Management: Focus on clearer communication from top leadership. Help maintain a more consistent work-life balance for project teams, especially around critical data center airflow management deadlines.
