We’re pioneering the discovery and development of life-changing medicines through the transformative power of artificial intelligence. Backed by Lightspeed, NEA and Sequoia.
About the role
At Xaira, we're building antibody discovery engines that feed AI-driven design at scale. We're looking for an accomplished protein biochemist to own phage display campaigns end-to-end within our Display Technologies group — designing selection strategies, cracking difficult targets, and turning campaigns into the high-quality datasets that train our antibody design models.
What they're looking for
- PhD in Molecular Biology, Biochemistry, Immunology, Protein Engineering, or related field, with 2–4 years of relevant industry experience
- Significant hands-on expertise in antibody/protein discovery by phage display — library design, panning/selection, and hit validation
- Hands-on flow cytometry (FACS) experience, including data interpretation and gating strategy
- Excellent analytical and problem-solving skills, with meticulous attention to detail and rigorous documentation
- Strong written and verbal communication, able to present complex science to technical and non-technical audiences
More about this role
Xaira is an innovative biotech startup focused on leveraging AI to transform drug discovery and development. The company is leading the development of generative AI models to design protein and antibody therapeutics, enabling the creation of medicines against historically hard-to-drug molecular targets. It is also developing foundation models for biology and disease to enable better target elucidation and patient stratification. Collectively, these technologies aim to continually enable the identification of novel therapies and to improve success in drug development. Xaira is headquartered in the San Francisco Bay Area, Seattle, and London.
