Current Need:
SK pharmteco Ireland are seeking to recruit a highly experienced Principal Scientist to lead a team in the process R&D group.
We are seeking a highly skilled and motivated Principal Scientist / Chemist to join our Process Development team within a dynamic CDMO environment.
The successful candidate will lead the development, optimization, and scale-up of robust, safe, and cost-effective chemical processes for the manufacture of Active Pharmaceutical Ingredients (APIs) and intermediates, from clinical through commercial stages.
This is a senior-level role that demands both technical expertise and leadership capabilities, with opportunities to mentor junior scientists and interface directly with clients and cross-functional teams.
As a Principal Scientist in API Process Development at our SK Pharmteco site you will play a key leadership role in delivering high-quality, innovative solutions for our global clients.
This role combines deep expertise in API process development with a passion for adopting cutting-edge technologies to drive efficiency, quality, and scalability across diverse development programs.
You will be responsible for leading the design, development, and scale-up of chemical processes for small-molecule APIs, while evaluating and implementing new manufacturing technologies such as continuous flow processing, process analytical technologies (PAT), and digital process optimization tools.
You will act as both a technical expert and a client-facing scientific leader, helping ensure successful development, technology transfer, and GMP manufacturing within tight timelines and regulatory frameworks.
Primary Responsibilities
Lead end-to-end development of API processes from route scouting through scale-up and GMP manufacturing for client programs across clinical and commercial phases.
Collaborate with clients and internal stakeholders to define development strategies, technology selection, timelines, and deliverables.
Evaluate and implement innovative process technologies to improve yield, robustness, scalability, sustainability, or cost-efficiency, including:
Continuous flow chemistry
Crystallisation development
Advanced automation and real-time data analytics
PAT tools and real-time release testing
Green chemistry principles and solvent reduction
Contribution to successful technology transfer into the site from clients or partner organisations, and from development to manufacturing.
Serve as the scientific lead in troubleshooting process issues during familiarisation, optimisation and scale-up, ensuring rapid and compliant resolution.
Perform risk assessments, identify and mitigate potential scale-up or safety issues (e.g., thermal hazards, exothermic reactions).
Develop and implement Design of Experiments (DoE) to optimise critical process parameters.
Collaborate closely with internal cross-functional teams including Analytical, Quality Assurance, Tech.
transfer, Manufacturing, Engineering, Supply chain and SHE.
Author and review technical documentation, including process development reports, risk assessments, and CMC regulatory submissions.
Stay current with emerging trends and technologies in chemical process development and apply them strategically to enhance client offerings.
Mentor and develop scientists within PR&D and contribute to a culture of innovation and continuous improvement.
Qualifications
Education
Ph.D. in Organic Chemistry, Chemical Engineering, or a related discipline.
