OSHA-required compliance testing is what the law asks for. What workers actually need is someone competent, calm, and prepared standing in front of them — running the test, explaining the result, and treating the moment with the seriousness it deserves.

That person is a Safety Responder. At MHD, it could be you.

We are looking for part-time Safety Responders to join a nationally distributed field team that delivers on-site occupational health and safety services for some of the most safety-critical employers in the country. The work is precise, hands-on, and rooted in protocol. The schedule is part-time with travel. The standard is non-negotiable.

If you have worn a uniform, run a call, or led a crew — and you miss being the person people trust when conditions get serious — this is built for you.

MHD is a nationwide on-site occupational health, safety, and industrial hygiene services company headquartered in Broomfield, Colorado. Since 2019, we have grown to 51 employees serving more than 2,000 organizations nationwide, including Northrop Grumman, Nebraska Medicine, NPR, and Owens Corning.

Our mission is Work Without Worry — helping employers stay OSHA compliant and keep their employees safe. Our brand promise is Safety Made Simple. Compliance Made Certain.

We deliver four signature compliance services in the field: Respirator Fit Testing, Audiometric Hearing Testing, Pulmonary Function Testing, and Noise Level Surveys. Our 10-year goal is to become the #1 private employer of veterans and retired first responders in the United States.

In your first 90 days, you will become certified in MHD's testing methodologies and complete supervised Work Orders alongside your Territory Manager. By six months, you will be the primary MHD presence at client sites across your region — running a full slate of OSHA-compliance testing, coaching client employees through the process, and delivering clean documentation within 24 hours of every visit.

By the end of year one, the clients on your route will know your name. They will ask for you by name. They will trust you to walk onto their floor, set up your equipment, and tell them the truth about what the data shows — because the person delivering the test is the person carrying the standard.

Specifically, the work involves:

• Conducting OSHA-required Respirator Fit Tests, Audiometric Hearing Tests, Pulmonary Function Tests, and Noise Level Surveys at client facilities.
• Delivering short, clear in-person safety training to client employees.
• Setting up, operating, and calibrating MHD's portable testing equipment on-site.
• Submitting complete, accurate electronic reports through MHD's field service platform within 24 hours of each visit.
• Representing MHD's brand at every client site — appearance, communication, and conduct that matches the trust our clients have placed in us.

Your day starts the night before. You confirm tomorrow's Work Order with your Territory Manager — site address, contact name, services scheduled, equipment list, certifications required. You load the vehicle, check the calibration on each instrument, and review the site's prior visit notes.

You leave early. Traffic, weather, and gate security are not the client's problems — they're yours. You arrive on time, walk in clean, and find your point of contact within the first five minutes.

You set up in the space the client gave you. You greet each employee who comes through, explain what the test does and why, run the protocol exactly as it was written, and answer questions in plain English. When a result is borderline, you do not round it. You run it again.

By the end of the day, you have tested between 20 and 60 employees, depending on the service. You break down your equipment, thank the site contact, and head out. That evening, your documentation is uploaded — clean, complete, accurate. Your Territory Manager sees it the next morning. The client sees their report within the week.

Some days you sleep in your own bed. Some days you don't. Either way, the standard is the same.

The strongest people in this role share four signals, regardless of background:

They treat standards as identity, not as rules. OSHA protocols, MHD's methodology, and the daily Clarify and Verify habit are not boxes they check. They are how the work gets done, because that is how the work should be done.

They lead with expertise, not authority. Clients trust them because they know the equipment, the standards, and the why behind every test — not because they raised their voice. When a client pushes back on a result, they explain it. When the explanation does not move the client, they hold the line anyway.

They are comfortable working alone, inside a structure. Most of the day is solo — you, your equipment, and a room full of employees who need the test done right. The structure comes from your Territory Manager, who handles the scheduling, equipment logistics, and client coordination so you can focus on delivery.

They never stop sharpening the craft. Certifications renewed before they lapse. New testing methods studied before they're required. Field-observed improvements brought back through the team. The day they stop learning is the day they stop being useful.

These are the four values our entire team is hired against, reviewed against, and promoted against. They are not posters on a wall. They are the operating system.

Sweat the Small Stuff. Details matter, and we obsess over getting them right. In every interaction with customers and colleagues, we strive for excellence. Exceptional service means paying attention to everything, big and small.

Have the Courage to Do What's Right. Honesty and integrity are at the core of everything we do. We make the tough choices to do what's right and put the good of the organization ahead of self-interest.

Own it! See a problem? It's yours to solve. We never assume somebody else will handle things, and we always take personal accountability to make things better.

Keep Climbing. We are all working to make a difference for our clients, and to do this we can never rest on our laurels. Our constant focus is on improving the organization, as well as ourselves.

We owe candidates a clear picture of what this role actually requires. Please read carefully before you apply.

Travel. You will deploy to client sites across your regional territory — typically a five-hour radius. Some visits are local. Some require overnight stays. Air travel happens occasionally for larger projects. If your life situation does not accommodate multi-day travel several times per month, this role is not the right fit.

Schedule. This is a part-time role with variable hours driven by client demand. Most weeks fall between two and four working days. We coordinate the schedule with you in advance, but the rhythm is not a fixed Monday-through-Friday calendar.

Physical demand. You will load, unload, and carry portable testing equipment — typically 25 to 50 pounds — between your vehicle and the client's testing area. You will stand, sit, and reposition for several hours at a stretch. Reasonable accommodations apply where legally applicable; the core mobility demand is part of the role.

Driving. You will operate a vehicle with testing equipment most working days. A reliable driving record and the ability to drive significant distances safely are required.

Certification maintenance. CAOHC (Council for Accreditation in Occupational Hearing Conservation) and NIOSH (National Institute for Occupational Safety and Health) certifications must be earned and maintained. MHD covers the cost of training and certification after you complete field training; the time and intellectual bandwidth to keep them current must come from you.

• $25.00 per hour, with a $200.00 daily minimum when deployed.
• Training and certification fully covered by MHD after successful completion of field training (CAOHC, NIOSH, and MHD-specific methodology training).
• All travel expenses covered when on company business — vehicle, lodging, meals, equipment transport.
• MHD equipment provided — you do not buy your own gear.
• Growth path — Safety Responders with strong tenure and demonstrated leadership are the talent pool from which we promote our Safety Responder Territory Managers and service-line specialists.

We are hiring Safety Responders in the following metropolitan areas:

• Hartford, CT
• Boston, MA
• Philadelphia, PA

Strongly preferred:

• Background as a retired or transitioning first responder (Fire, Law Enforcement, EMS) or Military veteran. Our field team is composed almost entirely of people from these backgrounds, and the culture is built around the discipline and presence that comes with that experience.
• A track record of working under pressure to a clear standard.

Required:

• Clear, professional verbal communication — comfortable speaking to small groups of client employees.
• Working proficiency with Windows and the Microsoft Office Suite (Outlook, Word, Excel, Teams).
• Clean driving record and ability to pass a background check.
• Willingness and physical capacity to travel multiple days per week within your regional territory.
• Comfort with occasional air travel for larger projects.

Helpful, not required:

• Prior experience with respirator fit testing, audiometric hearing testing, or other OSHA-compliance testing services.
• Knowledge of workplace safety practices.
• Bilingual proficiency in English and Spanish.

If you meet the strongly-preferred and required criteria and are missing some of the technical experience, apply anyway. We train for the methodology. We hire for the standard.

Submit your application through this listing. Strong candidates will be contacted by an MHD recruiter for a phone screen, followed by an in-person or video conversation with the Safety Responder Territory Manager for your region.

When you apply, tell us briefly: which metropolitan area you live in, your availability pattern (how many days per week, weekday or weekend preference), and one example of a time you held the line on a standard when it would have been easier not to.

MHD is an equal-opportunity employer. We evaluate candidates on the abilities and qualifications relevant to the work, and we do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, gender identity or expression, age, marital status, veteran status, disability status, pregnancy, parental status, genetic information, political affiliation, or any other status protected by applicable law in the locations where we operate.

We celebrate the differences our people bring to the team. The work we do is too important to be done by anything less than the best version of every person we hire.

The MHD Hiring Team
