Job Title: Scientist – Human Safety
Location: Colworth R&D, Sharnbrook UK – hybrid
JOB PURPOSE
At Unilever, we are committed to developing safe & sustainable products for our consumers. As a Toxicology Safety Scientist in our Safety, Environmental & Regulatory (SERS) team, you will provide scientific expertise to assure the safety of Unilever ingredients for consumers who use our products and the workers who make them.
You will be joining a team of safety scientists, where you will be supported in your own development, while also being expected to help others grow in their roles. You will work as part of multidisciplinary teams (including biologists, bioinformaticians, computational chemists, and mathematical modellers), to apply novel, mechanistic approaches to safety assessment.
In this role, you will lead defined technical workstreams or projects, applying established and emerging safety risk assessment methodologies to assess the human health risks associated with ingredients in consumer goods. You will represent Unilever externally providing ingredient stewardship for key ingredients/products and championing evidence based, exposure-led risk assessment based on industry best practice. Through industry working groups you will contribute to the development of regulations based on the best available safety science.
You will work alongside some of the industry’s most respected scientists, learning new risk assessment approaches, growing as a professional and enjoying opportunities to publish and present. In addition, of course, you will have fantastic career opportunities within a successful global company that is focused on winning every day.
The role is based in the dynamic environment of our SERS team at Colworth Science Park, Sharnbrook located near Bedford.
MAIN RESPONSIBILITIES
- Assess human safety risks associated with ingredients with an emphasis on applying novel (non-animal) approaches.
- Deliver transparent, well documented, exposure-based risk assessments to enable robust decision-making. This will include clearly communicating the outcomes of these risk assessments, providing input to broader communication to maintain trust in the safe use of Unilever products.
- Contribute to the evolution of our approach to exposure-driven risk assessment including working with external groups.
- Build an understanding of the wider issues surrounding the use of ingredients and products.
- Provide stewardship of strategically important ingredients by promoting robust exposure led human health risk assessment using best practice approaches.
- Actively engage with external stakeholders, such as trade associations and regulators, to represent Unilever’s interests and contribute to the development of industry best practices in human health risk assessment and regulatory frameworks for key products and ingredients.
ALL ABOUT YOU
You’ll need to be able to work effectively and with impact in cross-disciplinary teams and in multi-cultural environments, be flexible and willing to adapt within a fast-changing business environment.
We would expect the successful candidate to have:
- A degree (BSc/MSc or equivalent) in Toxicology or a related discipline with relevant experience in commercial product safety or industrial/occupational health
- Experience of toxicology/consumer safety risk assessment and its application in an industrial context (FMCG, healthcare setting)
- Awareness of novel, non-animal approaches to safety assessment and their potential application for decision-making
- Excellent written & verbal communication skills including ability to convey scientific subject matter in a simple manner
- Evidence of a creative, problem-solving mindset
- Highly self-motivated, with a proven track record of collaborating effectively in interdisciplinary teams
- Ability to work with scientists from other disciplines as part of multidisciplinary teams.
- Strong team player, as both a leader and a team member

- Post graduate experience or a higher degree/ qualification (e.g., PhD)
- Knowledge/Experience of product safety regulations and ingredient stewardship
- Project leadership experience

Recruitment Fraud
Cyber criminals advertise fake job adverts with prestigious employers as a way of stealing information or even defrauding individuals out of money. In the most sophisticated cases, they will set up fake websites, which have a similar address to companies like Unilever. They even conduct fake telephone interviews and then offer candidates a role with the proviso they pay a fee for background checks or to cover work visa costs. These types of attacks are becoming more common as more people are looking for employment in the economic climate.
How is Unilever tackling this?
Many of Unilever’s recruitment sites publish a warning to candidates about recruitment fraud. The Cyber Security team also proactively scan for signs of people setting up fake Unilever sites and act to close them down.
What can I do?
If you become aware of potential recruitment fraud, spot fake Unilever recruitment adverts or fake LinkedIn profiles, report them via Una Live Chat.
Unilever does not accept responsibility or liability for any candidates who are financially impacted by recruitment fraud. Your vigilance is key!
