About Thermo Fisher Scientific
At Thermo Fisher Scientific, we develop solutions that help people live healthier, cleaner, and safer lives. This is more than our mission — it is the impact our colleagues make every day.
At our Vilnius site, we develop and manufacture innovative life science and diagnostic technologies used by researchers, clinicians, and laboratories around the world. Our teams work in an international scientific environment where formulation science, chemistry, analytics, biology, product development, and manufacturing come together to create products that support customers globally.
Join a team where formulation development, scientific problem-solving, and collaboration help advance next-generation nucleic acid delivery technologies.
Job Overview
We are looking for an early-career Scientist, Synthetic Chemist to support the synthesis, purification, characterization, and scale-up of novel lipids and other molecules used in the development of nucleic acid delivery reagents.
In this role, you will work hands-on in the laboratory, support the development of synthetic routes, perform organic synthesis, purify and characterize compounds, and contribute to research and development activities. You will also gain exposure to process scale-up, analytical method development, and technology transfer activities under the guidance of experienced scientists.
This role is a strong fit for someone with a solid foundation in organic or synthetic chemistry who wants to grow in a product development environment. You do not need to be an expert in every area listed — we are looking for strong chemistry fundamentals, practical laboratory skills, accuracy, curiosity, and motivation to learn.
You will collaborate with R&D, Process Development, Analytical Development, Formulation, Manufacturing, and Quality teams, so teamwork, clear communication, and openness to working with different functions are important for success.
Key Responsibilities
Support the design, execution, and optimization of synthetic routes for novel lipids, intermediates, and small molecules supporting nucleic acid delivery technologies
Perform multi-step organic synthesis, reaction optimization, purification, and characterization of compounds
Contribute to small-scale and scale-up activities to produce materials for research, development, and manufacturing
Characterize synthesized compounds using analytical techniques such as HPLC/UHPLC, LC-MS, NMR, IR, and UV-Vis spectroscopy
Support troubleshooting of synthetic or analytical challenges together with senior scientists and cross-functional teams
Contribute to the development of robust, reproducible, and scalable synthetic processes
Prepare and maintain accurate electronic laboratory notebooks, technical reports, SOPs, protocols, batch records, and development documentation
Support technical documentation and activities related to process transfer to manufacturing and new product introductions
Gain exposure to analytical method development, qualification, and validation activities
Follow laboratory safety practices, GLP/GMP requirements where applicable, and data integrity standards
Collaborate with R&D, Process Development, Analytical Development, Formulation, Manufacturing, and Quality teams
Bachelor’s or Master’s degree in Organic Chemistry, Chemistry, Biochemistry, Pharmaceutical Sciences, or a related scientific discipline
0–2 years of relevant academic, internship, or industry experience, including thesis work, research projects, laboratory practice, or early industry experience
Hands-on experience or strong academic background in synthetic organic chemistry
Exposure to multi-step synthesis, purification, and characterization of small molecules, lipids, or related compounds
Working knowledge of analytical characterization techniques such as HPLC/UHPLC, LC-MS, NMR, IR, or UV-Vis spectroscopy
Good written and spoken English skills
