Senior Scientist – Right Particle

AstraZeneca UK

Location: Cheshire East

Job Type: Full time


AstraZeneca is a global, innovation-driven biopharmaceutical company where we not only focus on the discovery, development and delivery of life-saving medicines to our patients but believe in sustainability and are determined to minimise the impact of our work on the environment. We are proud to be a phenomenal place to work and have a culture that encourages innovation and collaboration. We empower our colleagues to express diverse perspectives and at the same time feel valued, respected and rewarded for their ideas and creativity.

Chemical Development:

In Chemical Development we believe that nothing is impossible, and we are determined to push the boundaries of science to deliver medicines to our patients. We combine peoples technical knowledge and understanding with their talent and drive to design, develop and optimise synthetic routes that deliver the active pharmaceutical ingredients of our medicines in a sustainable, commercially viable way. We believe in innovation and continuous improvement, working closely with colleagues in academia and across industry, to ensure that we apply the newest technologies and principles in the processes we develop.

We have an open position for a Senior Scientist in our Right Particle Team. The responsibilities and requirements of the position are outlined below.

As a Senior Scientist, you will be a scientific leader in our growing crystallisation and particle engineering community across Chemical Development.

Together with teams of colleagues in other departments and skill areas you will design, develop, optimise and scale-up challenging processes to robustly deliver materials with desired physicochemical attributes. You will also plan and drive improvement projects, use new technologies or modify our ways of working within AstraZeneca or externally with our Contract Development and Manufacturing Organisations (CDMOs).

Key role responsibilities include:

  • Provide crystallisation expertise in process development, process scale-up and manufacturability for drug substance and intermediates as an integral part of route development.
  • Champion and drive the sustainability of right particle processes with respect to environmental impact, efficiency and cost.
  • Drive the overall drug substance control strategy, ensuring processes are fully understood and will robustly deliver consistent drug substance quality.
  • Work collaboratively with colleagues in Drug Product Development to identify and define the required particle properties for downstream processing.
  • Deliver Chemistry Manufacturing and Controls (CMC) content and contributions to regulatory filings throughout the clinical development phase and commercial filings.
  • Act as a scientific expert to initiate, drive and deliver science and technology and other improvement projects within and outside Chemical Development.
  • Develop an external network (industrial and academic) to bring learning and innovative crystallisation and particle engineering science into AstraZeneca.
  • Tackle complex scientific problems.
  • Mentor and supervise junior colleagues.

Essential Requirements:

  • A degree and / or PhD in Chemistry or Chemical Engineering.
  • The ability to support multiple projects as a lead Right Particle scientist.
  • Provide laboratory-based expertise to project teams in the design and development of crystallisation and isolation processes, as an integral part of synthetic route development.
  • Experience in a range of particle/materials characterisation techniques.
  • Have the ability to independently represent the department and the Right Particle skill area within multi-functional teams.
  • The ability to work collaboratively with colleagues in a number of Drug Product departments to define desired particle properties for formulations, manufacturability and bioavailability.
  • Generating, reporting and interpreting high quality data with clear impact to development projects.
  • Ability to present information and engage in discussions in multi-disciplinary project teams.
  • Effective communication and influencing skills.
  • Continuously develop yourself and your colleagues via training and shared learning experiences to improve our efficiency and effectiveness
  • Ensuring own work is performed and recorded in accordance with appropriate Safety, Health & Environment (SHE), quality and compliance standards, e.g. Good Manufacturing Practice (GMP)

Preferred Requirements:

  • Experience of working in the Pharmaceutical or Fine Chemicals Industry.
  • Involvement with working with Contract Development and Manufacturing Organisations (CDMOs).
  • Knowledge of particle size reduction unit operations.
  • Proficiency with inline Process Analytical Technology (PAT).
  • Participation in the production of non-crystalline or large molecule New Chemical Entities (NCEs).
  • Some familiarity with modelling software (e.g. Aspen, DynoChem, gPROMS FormulatedProducts) to support process design and understanding.
  • Exposure to technology transfer and commercial production.
  • Experience of leading and driving improvement projects or new ways of working.
  • Collaboration with external partners investigating a new technology or process and implementing these within an industrial setting.
