Build Your Future. Join the Mission.
At IH Services, our people are the foundation of everything we protect — manufacturing plants, laboratories, clean rooms, and secure federal facilities. In places like these, the stakes are real: work left undone can stop a production line, and the wrong person inside the gate can put national security at risk.
That is where we work. We have done it since 1955 — and our people are hired, trained, and backed by us.

We hire year-round across our client sites. Every opening is posted on our job board.

Our full list of openings lives on our job board, where you can search by city, filter by schedule, and set an alert so we notify you when something opens near you. Every application goes there — straight to the hiring manager for the site, in one system, with no lost resumes.
More Than a Job. A Mission.



You deserve more than a paycheck. You deserve a place where your talents are recognized, your growth is real, and the work itself means something. Here, it does. When you maintain a defense plant, clean a laboratory to specification, or keep a federal facility running through the night, you are not background staff. You are the reason the mission continues without interruption.
America’s most secure facilities let very few companies through the gate. They trust IH Services because of our people — trained by us, backed by 70 years of showing up, and cleared to work where others wait outside.
Bring your full self and your best ideas. Ready. Secure. Lean. That is how we run facilities — and how we build careers.
Why People Stay Here
A career that feels like you — and what the job is actually like, in plain terms.
You know the site and the shift before you apply
Every posting names the location and the schedule. Ask the hiring manager about pay on the first call and you will get a straight answer.
Training before you are on your own
You learn our procedures, the safety requirements, and the rules of your specific site before you work alone. Floor care, sweeper and scrubber operation, and clean room work carry ongoing certification.
Sites that do not disappear
We hold long-term contracts inside plants, labs, and secure facilities. This is not seasonal work that ends when the weather changes.
A clearance is worth having
Many of our sites require eligibility for a federal security clearance. If you qualify, that is worth something here — and everywhere else you work for the rest of your career.
We promote from the floor
Our site supervisors and account managers came up through custodial and floor care work. Tell your supervisor where you want to go and we will show you what it takes to get there.
Our Values Are Part of Our DNA
Six things we hold ourselves to. The first one is why our clients call us instead of someone cheaper.
Safeguard Secure Environments
We safeguard secure environments by maintaining strict financial independence, deploying cleared professionals, and protecting our clients’ people, data, and mission-critical operations.
Respect People & Planet
We are committed to providing a safe, healthy, and inclusive workplace while minimizing our negative impact on the environment.
Strive for Excellence
We deliver quality solutions and best-in-class value for our clients, while keeping a positive outlook and consistently working hard to improve.
Foster Innovation
We value personal, professional and organizational growth and welcome innovation, adapting to emerging trends and customer needs.
Be Honest & Accountable
We build the trust of our stakeholders by being transparent, fair, and meeting our commitments.
Promote Collaboration
We are stronger together. Through our collaborative approach, we bring added value to our stakeholders and increased success for the Company as a whole.
The Work We Do
Five kinds of role, and what each one is really like.
Custodians & day porters
Keeping offices, plants, and common areas clean and safe while the building is running. Day, evening, and night shifts.
Floor care technicians & sweeper/scrubber operators
Stripping, sealing, burnishing, and machine-cleaning hard floors and large production areas. Equipment experience helps. It is not required to start.
Clean room & laboratory specialists
Precision cleaning under strict protocols, where a shortcut costs a client a production run. Detailed, disciplined work for people who take pride in getting it exactly right.
Maintenance, HVAC, electrical & plumbing technicians
Keeping building systems running. Licensed trades welcome — bring your license and we will talk about what it is worth here.
Site supervisors & account managers
Running a crew and owning a client relationship. Most of ours started on the floor at a site like the one you would be running.
How Hiring Works
From application to your first shift. No mystery, no ghosting.
1
Apply on our job board
Find your city, pick the role, and apply. Your application goes straight to the hiring manager for that site.
2
Phone screen & interview
The hiring manager for your site calls to walk through the role, the schedule, the pay, and the location. Ask them anything — it is easier to sort out now than after you start.
3
Background screening
We work inside secure and mission-critical facilities, so every role requires screening and some require clearance eligibility. If something in your history worries you, tell the hiring manager early. We would rather have the conversation than lose a good candidate to a surprise.
4
Training, then your first shift
You are trained on our procedures, the safety requirements, and your site’s specific rules before you work independently.
Know someone good?
Our best hires come from the people already working here. Refer someone, and when they stay, we pay you. Ask your supervisor or hiring manager for the current referral bonus.
Apply through our job board and the hiring manager for your site will contact you directly — and stay with you through every step, from first call to first shift.
