About Your Next Job

MAT Research is a pioneering company in the field of pyrogen testing, committed to ushering in a new era of ethical and accurate diagnostics. Since 2016, we have been leading the development of the Monocyte Activation Test (MAT), an animal-free alternative to traditional Rabbit Pyrogen Tests. Our ready-to-use MAT kits offer a robust and highly reliable method for detecting a broad range of pyrogens in parenteral drugs. ISO:9001:2015 certified, we uphold the highest standards of quality in all our products and services. By focusing on in-vitro human-based testing, we aim to drastically increase patient safety while saving hundreds of thousands of animal lives each year. We are steadfast supporters of the European Pharmacopoeia's vision to replace animal-based tests with MAT by 2026. For more details, go to our job page.


As we continue to scale, we are looking for a dedicated Manufacturing Scientist to play a crucial role in developing, optimising, and overseeing our biotech manufacturing processes. You will work at the intersection of scientific research, manufacturing operations, and quality control, ensuring consistency and scalability of high-quality product manufacturing and delivery within regulatory compliance.

This role is ideal for individuals with a strong scientific background in immunology and hands-on experience in biotech production environments.


About Your Next Colleagues

We are a small growing team of 9 dedicated people.

Our team members are adaptable, capable of wearing multiple hats when necessary. But with this flexibility comes a strong sense of responsibility. Every individual owns their role and the results that come with it.

Join a team that's making real change – by enhancing patient safety and saving animal lives.


About Your Tasks and Responsibilities

Your key responsibilities will include:

  • Manufacturing Process Development & Optimization

  • Work with cross-functional teams to troubleshoot and optimise production efficiency.

  • Oversee batch manufacturing processes, reagent preparation, and formulation of diagnostic kits.

  • Implement and enforce GMP, ISO:9001, and regulatory compliance standards.

  • Monitor key quality parameters and conduct in-process checks to maintain high product standards.

  • Collect and analyse process data to identify improvements and optimise manufacturing performance.

  • Conduct process validation studies to ensure reliability and compliance with regulatory requirements.

  • Collaborate with QA/QC teams to investigate process deviations and implement corrective actions.

  • Support technology transfer from R&D to manufacturing, ensuring seamless transition and implementation.

  • Drive process automation and integration of advanced bioprocessing techniques.

  • Train and mentor technicians and operators in best manufacturing practices.

  • Act as the technical expert for manufacturing-related challenges and improvements.

  • Work closely with R&D, Quality, and Regulatory teams to maintain alignment on product development and compliance.

We have developed an improved Monocyte Activation Test (MAT) for pyrogen testing. The MAT serves as the replacement for the Rabbit Pyrogen Test and can be used to test parenteral drugs for endotoxin and non-endotoxin contaminations. Our technology uses cryopreserved pooled PBMC. This has made it possible to develop a MAT with both high sensitivity and robustness, ensuring reliability in the field.
