Senior Scientist, Antibody Engineering

Metaphore is seeking a creative, resourceful, and highly collaborative multidisciplinary Senior Scientist to join our dynamic Platform Discovery and Engineering team. The ideal candidate will have previous industry experience with a strong multidisciplinary background supported by a solid track record in the discovery and characterization of therapeutic proteins, specifically monoclonal antibodies. Essential skills include a strong understanding of library display technologies, with an emphasis on phage display workflows.

In this role the candidate will be accountable to ideate, develop, and implement engineering and selection campaigns aimed at the identification and optimization of lead biologic molecules, as well as to mutagenize and deploy target libraries to characterize protein‑protein interactions. The ideal candidate will have the ability to excel in a collaborative multidisciplinary environment. We are looking for adaptive and scientifically curious individuals that will thrive in an ecosystem that encourages collaboration, growth, and learning.

• Design and execute phage display campaigns that unlock the therapeutic potential of molecular mimicry
• Collaborate with the broader Platform Discovery and Engineering team to help develop the group’s overall scientific strategy
• Drive the hit‑to‑lead process and in‑depth characterization and optimization of lead candidates
• Develop a strategy for successful high‑throughput antibody discovery and library‑based engineering using phage display (knowledge of yeast and mammalian systems is a plus)
• Contribute to therapeutic discovery program teams, leading screening/selection campaigns in a matrix environment
• Collaborate closely with Computational and Translational Sciences teams to inform both machine learning and preclinical development, specifically, analyze and interpret large datasets that characterize complex biology, thereby guiding Metaphore's innovative discovery engine
• Develop and validate ligand‑binding and cell‑based assays that enable hit characterization
• Support the continued protection, creation, and expansion of the company’s intellectual property
• Prepare and present comprehensive data packages and incisive analyses pivotal in driving program progression and strategic decision‑making

• 5+ years of experience in protein engineering, synthetic biology, molecular biology, biochemistry, or a related field. Prior industry experience in drug discovery or preclinical development is required, with a focus on antibody development preferred
• Deep technical expertise with phage display systems focusing on the generation of very high library diversity (familiarity with alternative platforms such as yeast, mammalian, and ribosome display is a plus)
• Proficiency in a variety of molecular biology techniques including, but not limited to, Golden Gate, Gibson assembly, construction of mutational libraries, and NGS sample preparation
• Experience with standard/phage‑based ELISA and familiarity with other methods of binding characterization, including HTRF, FRET, and SPR (flow cytometry experience is a plus)
• Proven expertise in discovery campaign design and optimization, and interpretation of results from a diverse array of assays and NGS readouts
• Familiarity with high‑throughput automation of display workflows is a plus
• Familiarity with the drug development process, including the advancement of molecules from discovery to IND is a plus
• Excellent communication skills, ability to clearly convey complex messages across multidisciplinary teams, and commitment to collaboration
• Scientific excellence, execution rigor, creative resourcefulness, critical thinking, attention to detail, great organization skills, and proven track‑record of achievement, as evidenced by publications in peer‑reviewed journals and contributions to the development of research and preclinical programs

• Molecular biology and protein biochemistry skills
• Experience with phage display
• Experience with high‑throughput selection/screening and NGS library preparation

We are seeking individuals with an entrepreneurial spirit, strong communication skills, and comfort working in and contributing to a dynamic and cross‑functional team environment. The level of the role will be commensurate with the education and years of experience of the identified candidate.

At Flagship, we recognize there is no perfect candidate. If you have some of the experience listed above but not all, please apply anyway. Experience comes in many forms, skills are transferable, and passion goes a long way. We are dedicated to building diverse and inclusive teams and look forward to learning more about your unique background.
