Imagine being the organised person who helps a growing company run smoothly while you’re still learning the ropes.
At LEX Diagnostics we’re scaling quickly and looking for an Office Administrator who’s organised, reliable, and ready to learn.
You don’t need years of office experience. What matters is that you’re organised, willing to muck in, and happy to pick things up as you go.
You’ll support the day to day running of the office and help the team stay on top of the small things that keep everything moving. As we grow, the role can grow with you, more responsibility, more variety, and a chance to build real workplace skills rather than just “helping out.”
We’re a friendly, down to earth bunch. Some days the office is quiet. Other days a delivery turns up and everyone pitches in. It’s varied, collaborative, and not a stuffy corporate environment. You’ll be part of a small team that helps each other out.
You’ll learn and then own the everyday running of the office, including:
You’ll be shown how things work. The job is as much about learning a professional routine as it is about already knowing every system.
We’re more interested in attitude than a long CV.
Useful but not essential, any admin, reception, retail, customer service, or school/college work experience. GCSEs or equivalent in English and Maths are helpful.
This is a full-time, onsite role based at our site in Melbourn near Royston
Why join LEX Diagnostics?
If you like being organised, don’t mind a bit of variety, and want a proper office job, then this is a good place to start.
