Senior Formulation Scientist

Introduction to role:

AstraZeneca is a global, science-led, patient-focused biopharmaceutical company that focuses on the discovery,developmentand commercialisation of prescription medicines for some of the world’s most serious diseases. Butwe’remore than one of the world’s leading pharmaceutical companies. At AstraZeneca, we are pioneering new frontiers byidentifyingand treating patients earlier, working towards the aim ofeliminatingcancer as a cause of death.Our Macclesfield Campus is a vibrant hub of development and manufacturing excellencewhere your work will directlyimpactpatients worldwide.

Come and join our AZ team where you will play a pivotal role in this exciting period of development!

Global Product Development (GPD)is the bridge that turns brilliant science into real medicines,designing,developingand industrialising formulations and processes that enable robust commercial manufacture. We build the formulation, manufacturing process and product understanding needed todevelop,scale, launch, and sustain new medicines. Youwill collaborate in highly multidisciplinary teams spanning analytical science, material science, engineering, biopharmaceutics,microbiology,devices/packaging, clinical and supply chain.

We are seeking a Senior Formulation Scientistspecialising inparenteral dosage forms toadvancelate-stageprojectsthrough to commercialisation.In this role,you will lead the rational design of robust, patient-centric formulationsforsynthetic small moleculesandnew modalities, includingoligonucleotidesandpeptides.You will collaborate closelywith process engineering and manufacturingteamson controlstrategies andcontribute to regulatory submissions and technology transfer. This role suits a scientist who is curious, data-driven, and collaborative, with a passion fortransformingscience into manufacturable sterile products that meet patient and commercial needs.

Accountabilities:

• Lead the design, development and optimisation of high-quality sterile parenteral formulations (e.g., solution, suspension, lyophile) from Target Product Profile and patient needs through to commercial readiness.

• Collaboratewith process engineers on aseptic processing, sterile filtration, terminal sterilisation, and lyophilisation cycle development to ensure manufacturability and scalabilityacrossclinical tocommercial phases.

• Author, review and integrate highquality CMC documentation for clinical and marketingapplications,includingresponses to questions and regulatory interactions.

• Apply risk management tools tohelpidentifyrisks and to prioritise relevant development studies.​​​​​​​

• Align formulationdevelopmentwith device and container closure strategy, packaging, analytics, microbiology/sterility assurance,biopharmaceutics,clinical and supply chain requirements.

• Champion innovation, continuousimprovementand knowledge sharing; contribute to publications,securing intellectual propertyand external collaborations whereappropriate.

• Maintainhigh standardsof data integrity, GMP awareness and laboratory safety; ensure documentation meets internal standards and external expectations.

Essential Skills/Experience:

• PhD in pharmaceutics, drug delivery, chemical/biochemical engineering or related discipline,orsignificantrelevantindustrial experience in drug product development.

• Strong grasp of how API physicochemical properties and excipient functionality influence solubility, stability, aggregation/particulates, tonicity, osmolality, and overall product performance.

• Proven experienceindesigning sterile parenteral formulations with understanding from development throughtocommercialisation.

• Practical understanding of aseptic processing principles, filtration compatibility, extractables/leachables, container closure integrity, and lyophilisation fundamentals.

• Experience with peptides, oligonucleotides, or othernewmodalities.

• ExperienceinauthoringregulatoryCMC sections and articulating product and process control strategies; familiarity withpostapprovalchange management is a plus.

• Proficiencywith DoE,statistical analysis,modellingand predictive tools to accelerate decisionmaking and derisk development.

• Strongcrossfunctionalpartnering and clear written/oral communication for technical and nontechnical audiences.

• Track recordof delivering to time, quality,and compliance in a dynamic portfolio environment.

Desirable Skills/Experience:

• Exposure to sterile filtration sizing, integrity testing strategies, terminal sterilisation by heat or radiation where relevant, and aseptic risk assessment.

• Understanding of methods supportingformulationand device/primary container compatibility(e.g., subvisible particles, aggregation, container closure integrity, extractables/leachables).

• Exposure to digital ways of working, automated workflows, or use of AI‑driven insights to support robust formulation and process understanding.

• Experience working with CMOs/CROs and managing productive technical relationships.

• Experience oforal solid dosageformsdevelopmentand manufacturing processes (e.g.continuous direct compression)

In Office Requirement:

When we put unexpected teams in the same room, we unleash bold thinking with the power to inspire life-changing medicines. In-person working gives us the platform we need to connect, work at pace and challengeperceptions.That'swhy we work, on average, a minimum of three days per week from the office.
