We are recruiting a full-time Cleanroom Technician to support operations at the Boulby Underground Laboratory, one of the UK's most unique and scientifically advanced research environments. This is not a standard cleaning role; it is a specialist position that plays a vital part in enabling world-class scientific research.
The role involves working across both surface and underground facilities, maintaining exceptional standards of cleanliness and contamination control. You will be part of a wider operational team, working closely with Mitie colleagues, scientists, and contractors in a safety-critical, highly controlled environment.
Responsibilities
As a Cleanroom Technician, you will be responsible for:
- Maintaining cleanroom environments to strict contamination control standards.
- Carrying out both scheduled and reactive cleaning activities across laboratory spaces.
- Supporting surface and underground operations.
- Following structured cleanroom procedures and protocols.
- Identifying and responding to cleaning, maintenance, and operational risks.
- Ensuring full compliance with health, safety, and site regulations at all times.
Requirements
We are looking for someone who brings more than just cleaning experience. The ideal candidate will:
- Take a proactive approach, showing initiative by identifying issues early, anticipating upcoming requirements, and preparing effectively for planned activities.
- Be a strong team player who works collaboratively with colleagues, scientists, and contractors.
- Communicate clearly and professionally.
- Contribute to a positive working environment.
- Have high attention to detail.
- Consistently maintain high standards and understand the importance of precision within cleanroom and scientific settings.
- Demonstrate pride in their work with a strong sense of ownership, professionalism, and personal standards.
- Be willing to learn and develop, showing openness to training in cleanroom procedures and a genuine interest in working within a scientific environment.
- Have a strong safety mindset, operating with a safety-first approach.
- Follow risk assessments and site rules.
- Feel confident to challenge unsafe behaviours in a regulated underground setting.
Reasons to use Rodeo
I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?
Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.
Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
