Do you have a strong interest in protein purification, chromatography, and bioprocess development? Do you want to contribute to the development of innovative purification technologies used in the production of life-saving biopharmaceuticals worldwide?

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.

As a Research Engineer, Chromatography Applications, you will play a key role in developing and optimizing chromatography applications for purification of biopharmaceuticals.

The position combines hands-on laboratory work with application and process development, focusing on purification strategies for antibodies and other biomolecules. 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.

• Develop and optimize applications within protein purification and chromatographic processes for biopharmaceutical applications.

• 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.

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.

• Degree in Biochemistry, Biotechnology, Chemical Engineering, Life Sciences, or a related field.

• 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.

• Strong written and verbal communication skills in English.

• 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.

To succeed in this role, you are a positive, curious, and solution-oriented person with a genuine interest in learning and developing new skills. 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.

Please submit your application no later than June 10, 2026.
