Sunresin is establishing its European center for chromatography innovation in Uppsala, and is now looking for a Research Engineer, Chromatography Applications to join the growing team. In this role, you will play a key part in developing and optimizing chromatography applications for biopharmaceutical purification. This is a unique opportunity to become part of an exciting growth journey and help build a new application development function within a leading global organization. About the Role

As a Research Engineer, Chromatography Applications, you will play a key role in developing and optimizing chromatography applications for purification of biopharmaceuticals. You will support experimental design, process optimization, and application development in a collaborative and growing organization. This role offers the opportunity to work in an international environment and engage with customers, collaboration partners, and industry experts through conferences and industry events. Plan, execute, and analyze laboratory experiments related to chromatography, separation, and purification processes, including troubleshooting and evaluation activities. Develop purification strategies for antibodies and other biomolecules using affinity chromatography, ion exchange chromatography, hydrophobic interaction chromatography (HIC), and multimodal chromatography. Operate and maintain chromatography systems and perform column packing activities. Design experiments and apply high-throughput methods for process and application optimization, including scale-up activities from laboratory (small) to pilot scale. Evaluate, document, and communicate experimental results to support development activities and customer projects. Represent Sunresin at international scientific conferences, customer meetings, and industry events, while strengthening Sunresin’s presence within the global biopharmaceutical community. Your Profile

We are looking for a motivated and collaborative professional with a strong scientific foundation and hands-on experience in protein purification and chromatographic process development. You enjoy working both independently and as part of a team, and you are driven by solving technical challenges and continuously expanding your expertise. At least 1 year of hands-on experience in protein purification and chromatography, including affinity chromatography, ion exchange chromatography, hydrophobic interaction chromatography (HIC), multimodal chromatography, and column packing/evaluation. Experience operating chromatography systems such as ÄKTA or equivalent platforms. Experience in experimental design and process development, including parallel high-throughput methodologies. Skilled in planning and executing experiments, as well as evaluating, documenting, and presenting results both orally and in writing. Desirable qualifications:

Experience from bioprocessing or biopharmaceutical development environments. Familiarity with monoclonal antibodies, antibody variants, or related biomolecules. Knowledge of process optimization, scale-up, and technology transfer activities. You enjoy solving technical challenges, working collaboratively with others, and contributing to a supportive team environment. With an analytical mindset and an open approach, you thrive in an international and collaborative setting and are motivated by continuous professional growth. They are now building a high-performing team that combines research, development, and manufacturing capabilities under one roof. Backed by the strength of a multinational group and driven by innovation at the local level, we are creating an environment where expertise, collaboration, and growth go hand in hand. Our mission is to provide cutting-edge purification technologies that support the development of life-saving therapies worldwide.
