Referso Jobs

Oversee production across mammalian, bacterial, and cell-free systems, including end-to-end workflows for construct design, expression, purification, characterization, quality control, normalization, and assay-ready handoff.
Drive innovation for difficult antigens and complex proteins through construct and boundary optimization, tag and format selection, alternate expression systems, site-specific labeling, automation, and other enabling technologies.
Establish fit-for-purpose production, purification, and characterization standards for attributes including yield, purity, aggregation, concentration, identity, oligomeric state, stability, and biotinylation.
Lead portfolio planning, prioritization, and resource allocation for the team across internal and outsourced production and characterization activities.
Manage relationships with CROs, technology providers, and other external partners, and communicate progress, risks, resource needs, and tradeoffs to senior stakeholders.
