Scientist Protein Production

BioArctic is looking for a skilled Scientist in Protein Production to strengthen our laboratory capabilities in recombinant protein expression and purification. This role includes planning, executing and troubleshooting small-scale protein production in mammalian expression systems, E. coli and potentially other relevant platforms, and developing and optimizing purification workflows.

In this role you would work with a broad range of protein modalities such as monoclonal antibodies, bi- and multispecific antibodies, antibody-fusion proteins, enzymes, ADCs, and other complex protein formats, adapting methods to each modality. Maintaining high laboratory standards, ensuring accurate documentation, and contributing to continuous improvement of workflows are essential aspects of the role.

Overall responsibilities

• Plan, execute and troubleshoot small-scale protein production in mammalian expression systems, such as transient expression in ExpiCHO and Expi293.

• Express recombinant proteins in E. coli and potentially other relevant expression platforms, selecting appropriate systems based on project needs.

• Perform downstream purification using ÄKTA chromatography systems, including affinity, ion exchange (e.g. IEX) and preparative SEC, and develop/optimize purification protocols when needed.

• Maintain high laboratory standards, including accurate documentation, compliance with internal procedures and contribution to continuous improvement of workflows and methods.

Education

Required experience

• More than 5 years of experience in the biotech industry, with a focus on protein expression and purification

• Extensive experience in transient protein production in mammalian expression systems, including platforms such as ExpiCHO and Expi293.

• Hands-on experience with protein expression in E. coli and other relevant expression systems.

• Proficient in ÄKTA-based protein purification, such as affinity chromatography, ion exchange (IEX) and preparative size exclusion chromatography (SEC).

• Experience of purification method development and maintenance/troubleshooting of purification instruments.

• Experience in working with a broad range of protein modalities, such as monoclonal antibodies, bi- and multi-specific antibodies, antibody-fusion proteins, enzymes, ADCs and other complex protein formats.
