About The Role
Pharmaron is seeking an entry-level or experienced Scientist, Process Chemistry to join our expanding Process Chemistry team in Hoddesdon.
Important Eligibility Requirements
- Please note that we are unable to offer visa sponsorship or support with work permit applications for this position. Applicants must therefore already have the unrestricted right to work in the UK and must not require sponsorship now or in the future.
- Applicants must also have already completed their MSc or higher qualification at the time of application. Unfortunately, we cannot consider applications from current students who are due to graduate in 2027.
Our Process Chemistry group delivers complex pharmaceuticals for clinical trials and marketed products, working with pharmaceutical and biotechnology partners across the globe.
Operating at the forefront of active pharmaceutical ingredient development, our scientists design synthetic routes, discover new reactions, and transform them into robust, scalable, and commercially viable manufacturing processes. We use advanced technologies, including robotics-enhanced reaction screening, machine learning models, and statistical tools, while collaborating closely with scientific teams across Pharmaron’s global network.
As part of an international organisation with world-class capabilities spanning discovery, development, and manufacturing, you will have the opportunity to build your scientific expertise while contributing to diverse and technically challenging projects.
The Opportunity
In this role, you will:
- Contribute to the design and execution of synthetic chemistry experiments supporting API development projects.
- Develop practical, robust, and scalable synthetic routes for pharmaceutical compounds.
- Work collaboratively within multidisciplinary project teams to achieve key milestones and client objectives.
- Support process optimisation, scale-up, and technology transfer activities.
- Learn and apply best practices in process development, scale-up, and GMP manufacturing.
- Interpret experimental data and use your findings to guide process development.
- Communicate scientific results and recommendations clearly and effectively.
- Maintain accurate laboratory documentation and electronic records.
- Operate within a strong culture of safety, quality, and scientific excellence.
