Senior Research Engineer, Sunresin

Sunresin is a newly established subsidiary of a leading global manufacturer of chromatography resins, now building its European hub in Uppsala, Sweden. The site brings together research, development, and production of agarose-based chromatography resins and affinity ligands, supported by a strong multinational group. 

The lab at the Sunresin Uppsala site is starting to take form and most things are coming into place. Therefore, they are looking for a Research engineer to join the team. 

As a Research Engineer, you will strengthen the analytical team at the new Uppsala site. In this role, you will contribute hands-on in the laboratory in close collaboration with research and development, with a primary focus on supporting the development of protein purification processes and chromatography media. As Sunresin at Uppsala is in a start-up phase the role will evolve as Sunresin grows and it is a good fit for someone who likes taking on new responsibilities without losing structure or direction.  

Your responsibilities will include implementing and validating immunoassays, as well as establishing and performing other analytical methods.

• Implement and validate immunoassays, primarily ELISA. 

• Perform and optimize electrophoresis-based methods. 

• Support protein purification process development through analytical characterization. 

• Conduct protein identification, quantification, and activity assays. 

• Perform HPLC and other relevant analytical techniques. 

• Document and ensure quality compliance according to applicable standards. 

• Collaborate cross-functionally with resin chemistry, ligand development, and production teams. 

The company is located in Uppsala Business Park, and you will be part of a growing team.  

You hold a degree in Biotechnology, Chemistry, Biochemistry, or a related field, and have hands-on laboratory experience in protein analytics.  

You have demonstrated experience in: 

• Independently implementing and validating ELISA methods.

• Working with electrophoresis techniques.

• Applying protein analytical methods such as HPLC, activity assays, and quantification methods.

As a person, you are structured, analytical, and curious. You thrive in a hands-on role that combines laboratory work with problem-solving and cross-functional collaboration. You are comfortable in a growing organization where processes and structures are still evolving. This role suits someone who remains confident even when not all the answers are in place, you take ownership of your work and collaborate closely with colleagues to find the right way forward.
