10368 The Business Unit Almac Sciences provides a wide range of custom synthesis services, technologies and products to the pharmaceutical industry, supporting clients from drug discovery through to commercialisation of new chemical entities. The business offers solutions aimed at accelerating entry into early-stage clinical development and supports the development and manufacture of small molecule and peptide therapeutics. Within small molecule API development platform at Almac, we deliver intelligent processes to deliver safe, agile and scalable chemistry and API manufacture from early development through to commercial supply, integrating non-GMP and kilo-lab capabilities, cGMP manufacturing in Craigavon, and key technical platforms from specialists in flow chemistry, biocatalysis and physical sciences.

Advancing human health requires exceptional people. Your talent, experience and passion will help us make an exceptional difference to the health of patients around the world. The Opportunity We are seeking Small Molecule Chemists at various levels to join our Early Phase and Late Phase Chemical Development and Custom and Flow Chemistry teams in Craigavon. These roles will support the design, development, optimisation, intensification, scale-up and delivery of synthetic chemistry and process development activities for small molecule APIs, key intermediates, and related pharmaceutical development projects spanning the preclinical to commercial landscape.

Depending on experience, successful candidates will contribute to client projects ranging from early route scouting and gram-scale synthesis through to process optimisation, kilo-lab transfer, non-GMP manufacture, cGMP manufacturing support, late phase process development and commercial launch. The roles will involve high-quality experimental design and execution, technical troubleshooting / problem solving, clear process documentation generation, strict adherence to cGMP quality systems, strong safety awareness, and effective communication with multidisciplinary project teams and clients.

These opportunities are suitable for candidates ranging from early-career chemists seeking structured development through to experienced chemists capable of providing technical leadership across synthetic, process chemistry and scale-up projects.
