R&D Bioprocessing Scientist

Are you a passionate scientist ready to push the boundaries of research and development? Join our dynamic R&D team as an R&D Scientist I, where you’ll spearhead groundbreaking experiments, analyze cutting‑edge data, and contribute to revolutionary product advancements.

At Meissner, we provide B2B technical solutions, that are deployed to improve the human condition. Our customers use our products and technologies to develop new therapeutics and many familiar products that support our modern lifestyle. At the core of these products, are in‑house technologies that are developed and maintained by highly talented and self‑driven engineers and scientists.

• Contributing to formulations, material testing, and recommendations while correlating material properties and filtration studies to processes.
• Developing new filters, filtration membranes and application‑specific products to meet emerging technological needs.
• Managing projects with a focus on deliverables, knowledge sharing, and collaboration across teams to ensure successful outcomes.

We are looking for a self‑driven candidate who is motivated to make an impact in the development of new technologies and join a dynamic entrepreneurial team. The R&D Scientist I independently plans and executes scientific experiments to develop innovative products, improve processes, and generate data that supports technical and business objectives. This role contributes scientific insight, leads segments of R&D projects, and supports cross‑functional collaboration to drive innovation and commercialization.

• Design, execute, and analyze complex experiments with minimal supervision. This may include upstream experiments to support cell culture and bioreactor process development.
• Develop and optimize formulations, processes, and analytical methods.
• Interpret data (including cell culture performance) and translate results into actionable recommendations.
• Hands‑on experimental work involving the characterization of material properties, set up, operation, and maintenance of bioreactors across batches, fed‑batch, and perfusion modes (ATF/TFF).
• Process development work in the laboratory involving testing equipment, chemical processes, and testing materials and products (membranes, filters, polymers, etc.) inclusive of mammalian suspension cell work (CHO and HEK
  293 lines using both 2D and 3D culture systems).
• Carry out filter testing, failure analysis, lifetime studies, comparative performance evaluations using appropriate instrumentation that may involve chemical analysis, microscopy, thermal and mechanical properties evaluation.
• Operate both single‑use and glass bioreactor systems and associated equipment (controllers, pumps, perfusion setups, hollow‑fiber filters).
• Lead small‑scale R&D projects or technical work streams, including resource planning and coordination.
• Prepare detailed technical documentation, including protocols, reports, and presentations.
• Maintain documentation and support SOP development as we build out upstream lab capabilities.
• Collaborate with cross‑functional teams (Engineering, Production, MTS) to support product development scale‑up.
• Stay current with relevant scientific literature, technologies, and competitive trends.
• Mentor junior scientists and research associates as needed.
• Ensure compliance with all safety, quality, and regulatory standards.

• Bachelor’s degree in STEM‑related field relevant to the operations of the organization with 5+ years of relevant experience or Master’s degree with 2+ years of relevant experience or PhD with 1+ year of experience.
• Strong foundation in relevant scientific principles and laboratory techniques.
• Proficiency with different laboratory instrumentation used in characterizing material properties.
• Experience in experimental design, statistical analysis, and technical problem‑solving.
• Proven capabilities in writing effective reports and data analysis.
• Excellent attention to detail and documentation practices.
• Demonstrated ability to lead portions of R&D projects and contribute to project strategy.
• Mechanical aptitudes (operation of power tools, equipment…
