Reading Scientific Services – Why Work With Us?

RSSL is a leading Contract Research Organisation (CRO) with a focus on product development, analytical testing, training and consultancy. Our purpose is to help clients overcome the scientific and regulatory challenges they face, either by performing the science on their behalf, or empowering their staff to do it themselves. Pharmaceutical and food companies outsource services to us as experts in our field and we deliver high quality technical solutions in return.



  • Are you looking to advance your career by joining a growing team committed to enhancing the lives of consumers and patients through science?
  • Do you share our passion for science and want to work for some of the world’s most innovative food and pharmaceutical companies?

Then take a look at what we have to offer.

Not only that. As part of Mondelēz International, we are in the enviable position of enjoying agility and autonomy, while also benefiting from the support of the biggest snacks company in the world.

Whether it be helping clients get vital drugs and treatments to patients, tackling industry issues such as a contamination or bringing a new product to market, we use our multidisciplinary scientific expertise to enhance lives.


Being part of RSSL means benefiting from career development opportunities and our company’s strong belief in ‘growing our own people’.

Both sites offer advantages. At Wokingham, you benefit from a recently refurbished, purpose-designed laboratory space, while the RSC is surrounded by 130 hectares of beautiful parkland thanks to its position on Reading University Campus. A favourite spot of ours is the University’s botanical garden – The Harris Garden – which is just a mere minute’ s walk away and freely accessible for us to enjoy whenever we can.

    Hugely supportive during Covid upheaval. Teams have pulled together admirably to keep all on site safe, sanitised and connected. Proud to be in a company making a positive impact to our pharmaceutical customers


    Change to normal working with being open over 7 days week required flexibility but small price to pay

    Easy Interview


    I applied through a recruiter. The process took 2 weeks. I interviewed at Reading Scientific Services.


    I received a call from a recruiter, who set up a phone interview for the next day. The phone interview lasted around an hour, and I was told I’d get a call the following week if there was an in person interview. I received a call two days later, inviting me next week to and in person interview, which lasted around an hour and a half. They asked me more questions and gave me a few simple problems to solve.
