The BioDesign Protein Biohemistry group at Biogen is seeking a creative and self-motivated scientist to contribute to our mission to design and develop medicines to transform patients’ lives. The successful candidate will play a key role in designing, generating, and characterizing antibody-oligonucleotide conjugates intended to improve the delivery of therapeutic oligonucleotides (ASOs or siRNAs) to target tissues.  This role requires a strong background in protein chemistry with extensive experience in bioconjugation and a deep understanding of linker design and optimization to improve the stability, efficiency, and efficacy of antibody-oligonucleotide conjugates. 

What You’ll Do 

• Optimize and implement protein purification schemes for engineered antibodies using computer-interfaced chromatography systems (e.g., AKTA or similar) 

• Characterize proteins using standard methods such as SDS-PAGE, analytical size-exclusion chromatography, and dynamic light scattering 

• Work with a cross-functional team to design and test novel linker chemistries to enhance conjugate stability and performance 

• Develop and optimize novel antibody-oligonucleotide conjugation and purification methods 

• Generate, purify, and analyze antibody-drug conjugates for use in animal models. 

• Actively contribute to project strategy and experimental design, and regularly present findings at team meetings 

• Troubleshoot technical challenges and drive continuous improvements in conjugation and purification workflows 

Who You Are 

The ideal candidate has a strong background in bioconjugation methods, a passion for science, and a genuine enthusiasm for collaborating within a cross-functional team.

• Strong analytical skills and proficiency with standard protein characterization methods (e.g., SDS-PAGE, size-exclusion chromatography and DLS). 

• Experience with antibody-oligonucleotide conjugation techniques, including click-chemistry and site-specific methods. 

• Demonstrated ability to independently design, plan, execute, and interpret complex experiments. 

• Excellent written and verbal communication skills. 

Preferred Skills 

• Experience with linker design 

• Experience with antibody-oligoconjugate quantitation and stability assays
