Senior Scientist – Iron Complex Process Development (R&D) - JG

About the Role A pharmaceutical R&D organization specializing in injectable and API products is seeking an experienced Process Development Scientist to join its Iron Complex Development team. This role is ideal for a candidate with strong, hands-on experience in iron chemistry who wants to lead process development from lab scale through technology transfer. Key Responsibilities

• Develop and optimize ferric and ferrous iron complexes and related iron-based products
• Design and execute laboratory and pilot-scale experiments for new product development
• Work on reaction chemistry, complex formation, precipitation, oxidation/reduction, pH, temperature, reaction time, and other process parameters
• Develop processes for iron sucrose, iron polymaltose/iron hydroxide polymaltose complexes, ferric carboxymaltose, iron isomaltoside, and related iron-carbohydrate or iron-polymer complexes
• Optimize critical quality attributes including molecular weight, particle size, PDI, iron content, oxidation state, solubility, stability, and purity
• Troubleshoot precipitation, aggregation, color changes, molecular-weight variation, yield, and batch-to-batch consistency issues
• Develop and document process parameters, batch procedures, development reports, and scale-up protocols
• Coordinate with Analytical, QC, QA, Production, and Engineering teams during development and scale-up
• Support pilot trials, process scale-up, technology transfer, and validation batches
• Evaluate raw materials and assess their impact on process performance and product quality
• Interpret analytical data such as GPC, particle size, zeta potential, iron assay, and elemental analysis
• Maintain laboratory records and prepare technical development reports Required Qualifications
• M.Sc. or M.Tech. in Chemistry, Pharmaceutical Chemistry, or a related field
• 5–7 years of hands-on experience specifically in iron compound / iron complex development (required)
• Strong practical knowledge of iron chemistry and coordination/complex chemistry
• Working knowledge of iron oxidation-reduction chemistry
• Experience controlling pH, temperature, reaction time, concentration, and addition sequence in process development
• Familiarity with iron-carbohydrate and iron-polymer complexes
• Experience in process optimization and scale-up from lab to pilot scale
• Strong analytical, troubleshooting, and technical documentation skills Preferred Experience
• Background in pharmaceutical/API development of parenteral iron products or injectable iron complexes is highly preferred What We Offer
• Opportunity to lead end-to-end development, from lab work to technology transfer
• Collaborative, cross-functional R&D environment
