Join the team and become part of a company growing thanks to the commitment of those who live it every day. We are looking for a Expert in high-pressure chromatography with a strong background in peptide purification and process scale-up. The ideal candidate has several years of hands-on experience developing, optimizing, and implementing robust purification methods from R&D to large-scale, including GMP manufacturing environments. This role requires deep technical expertise, problem-solving ability, and the capacity to work cross-functionally with R&D, process development, manufacturing, and quality teams. Key Responsibilities Develop and optimize chromatographic purification methods for synthetic peptides using high-pressure systems (Reverse Phase-HPLC) and other ancillary technologies (Ion Exchange, Size Esclusion Chromatography); Scale purification processes from lab to pilot and production scale, ensuring robustness, reproducibility, and regulatory compliance; Select, configure, and validate chromatographic equipment, columns, resins, and system parameters; Design and execute experiments to evaluate critical process parameters and performance attributes; Troubleshoot complex purification challenges, including impurities, yield loss, peak splitting, column degradation, and pressure limitations; Implement process control strategies and participate in tech transfer to manufacturing; Support process characterization, validation, and documentation (SOPs, batch records, development reports); Work closely with analytical, upstream/solid-phase synthesis, and formulation teams to ensure seamless integration along the peptide production workflow; Stay current with emerging technologies and approaches in chromatography and peptide purification. Required Qualifications Advanced degree (PhD or MSc) in Chemistry, Analytical Chemistry, Industrial Chemistry, Chemical Engineering, or related disciplines; 5–10+ years of hands-on experience with high-pressure chromatography applied to peptide purification; Demonstrated expertise with method development, process optimization, and scale-up for preparative HPLC; Strong knowledge of column chemistry, stationary phases, pressure limits, and peptide behavior under chromatographic conditions; Experience in purification at pilot and manufacturing scale, ideally in a regulated environment (GMP preferred); Proficiency in chromatographic software and method modeling tools; Excellent troubleshooting, documentation, and communication skills; Knowledge of downstream unit operations beyond chromatography (ultrafiltration/diafiltration, lyophilization, crystallization). Preferred Experience Industrial experience in peptide therapeutics, CDMO, or specialty chemicals; Familiarity with continuous chromatography, simulated moving bed systems, or preparative UPLC. Key Competencies Strong technical leadership and ownership of purification workflows; Ability to design experiments and interpret complex data rapidly; Cross-functional collaboration and mentoring of junior scientists; Quality-minded, detail-oriented, and comfortable in a fast-paced environment. Office location FIS Head Quarters is located in Montecchio Maggiore (Vicenza).
