- Proven track record of critically evaluating and applying scientific literature to support project objectives.
- Strong written and verbal communication skills with the ability to present technical data clearly.
- Proactive team player who asks for input when needed and thrives in a fast-paced environment.
- Prior hands-on experience in antibody discovery, biologics research, or immune-mediated assay development.
- Familiarity with GLP or GLP-like study conduct, including documentation standards, protocol adherence, and data integrity practices for regulated studies.
- Experience isolating primary human immune cells (e.g., PBMCs) and performing ex vivo functional assays.
- Prior experience in a startup or early-stage biotech environment, including building SOPs, establishing laboratory workflows, or standing up new capabilities with limited infrastructure.
