Organic Chemist (m/f/d)

Who are we

BioTreasure is an integrated biology and chemistry manufacturing platform designed to produce bio-based chemicals at industrial scale. Funded by SPRIND and developed in collaboration with Insempra, it combines circular continuous fermentation with proprietary downstream chemistry to enable flexible, local production, delivering performance, cost efficiency, and scalability from day one.

We offer:

• Join an early-stage startup creating real impact for the environment and society, where ideas truly matter
• Be an early hire in the team, with real ownership and hands-on involvement in building, shaping, and scaling the company from day one
• Gain real-world hands-on experience with access to a fully equipped lab, cutting-edge technology, and significant room for personal and professional growth
• Work within an international, fast-moving team with an open feedback culture, flat hierarchies, rapid decision-making, and English as the working language

For this position you will perform the following duties:

• Optimize multi-step organic syntheses, such as metathesis reactions for industrial application to improve yield, selectivity, throughput, and cost efficiency
• Scale laboratory reactions (gram scale) to pilot and production scale (kilogram scale and beyond)
• Scale highly reactive oxidative processes, such as ozonolysis in a controlled and safe manner
• Troubleshoot scale-up challenges including mixing, heat transfer, mass transfer, and impurity formation
• Support technology transfer and oversee initial production batches
• Purify products using column chromatography, recrystallization, and distillation
• Characterize compounds using NMR, IR, MS, HPLC, and GC
• Prepare process documentation including SOPs, batch records, and validation reports and detailed laboratory notebooks
• Ensure compliance with GMP, environmental, and safety regulations
• Collaborate with internal and external partners, reliably document and store data and results and clearly communicate updates

Your profile:

• MSc or PhD in Organic Chemistry, Process Chemistry, or related field (BSc with significant industrial experience considered)
• 3+ years of experience in process development or scale-up chemistry in pharmaceutical or fine chemical industries
• Knowledge of reaction kinetics, thermodynamics, and process safety
• Experience with pilot plant operations and manufacturing support
• Preferred experience with Olefin metathesis catalysts and Industrial ozonolysis and oxidative cleavage reactions
