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
