Job Description

Senior Production Scientist – Organic Synthesis

Work Location: Rockford, IL

As part of the Thermo Fisher Scientific team, you’ll discover meaningful work that makes a positive impact on a global scale. Join our colleagues in bringing our Mission to life every day to enable our customers to make the world healthier, cleaner and safer. We provide our global teams with the resources needed to achieve individual career goals while developing solutions for some of the world’s toughest challenges.

How will you make an impact?

As a Senior Production Scientist – Organic Synthesis, you will play a key technical role in the manufacture of specialty chemical products within an ISO-regulated, Lean manufacturing environment.

You will independently perform small- and medium-scale organic synthesis, supporting the production of small-molecule crosslinkers, biotinylation reagents, resins, and other compounds at scales ranging from milligrams to kilograms. You will apply your expertise in organic chemistry and analytical techniques to troubleshoot processes, improve manufacturing performance, support new product introductions, and maintain high standards for quality and safety.

As a senior member of the laboratory team, you will also train and mentor less-experienced scientists and help drive continuous improvement across manufacturing operations.

What will you do?

• Independently perform small- and medium-scale organic synthesis for products ranging from milligram to kilogram scale.
• Manufacture small-molecule crosslinkers, biotinylation reagents, resins, and other specialty chemical products in accordance with approved manufacturing procedures.
• Operate laboratory and production equipment including analytical balances, round-bottom flasks up to 72 L, glass reactors up to 100 L, chromatography columns, rotary evaporators, and vacuum drying ovens.
• Perform in-process and final-product analysis using techniques including NMR, TLC, FTIR, UV/Vis, and HPLC.
• Apply analytical methods and organic chemistry expertise to troubleshoot reactions, processes, and product-quality issues.
• Execute manufacturing activities in accordance with manufacturing records, standard work instructions, SOPs, and applicable ISO and quality requirements.
• Maintain accurate and complete production documentation and support an audit-ready laboratory environment.
• Coordinate production activities within assigned areas to help the team achieve weekly manufacturing targets.
• Train and mentor scientists and production associates, partnering with management to establish and achieve cross-training objectives.
• Lead or support root-cause and corrective-action investigations related to manufacturing, quality, and product issues.
• Evaluate customer feedback and product complaints and ensure investigations are thorough and completed on schedule.
• Serve as a Manufacturing representative on multiple concurrent New Product Introduction (NPI) teams.
• Develop and support NPI and manufacturing documentation, including manufacturing batch records (MBRs), bills of material (BOMs), hazard assessments, and incoming specifications.
• Partner with commercial and technical teams to evaluate the feasibility of custom and large-volume production opportunities.
• Support process and equipment validation activities and provide technical input for new equipment purchases and cost justification.
• Drive Practical Process Improvement (PPI), Lean, and 5S initiatives to improve safety, quality, efficiency, and laboratory organization.
• Maintain assigned production metrics and support metrology activities necessary to keep laboratory equipment compliant and audit-ready.
• Maintain a clean, organized, and safe laboratory environment and reinforce laboratory standards across the team.
• Identify opportunities to improve laboratory safety and coach others on the safe handling of hazardous chemicals.
• Perform other projects and responsibilities as assigned.
