Company

hirify.global combines frontier AI models, large-scale compute, biological foundation models, and experimental laboratory capabilities to accelerate scientific discovery and disease research.

What you will do

• Investigate cellular and molecular mechanisms regulating T cell responses and interactions within tissue microenvironments.
• Design, perform, analyze, and troubleshoot independent in vivo experiments using mouse models.
• Characterize immune cell differentiation, function, and interactions with other cells.
• Apply molecular biology, single-cell sequencing, spatial transcriptomics, genetic perturbation, and related experimental technologies.
• Integrate cellular, molecular, and spatial datasets with experimental and computational scientists.
• Present findings, prepare manuscripts, contribute to laboratory development, and mentor junior researchers.

Requirements

• PhD in molecular biology, bioengineering, genetics, cell biology, immunology, or a related field.
• 3+ years of experience with demonstrated impact in experimental molecular and cellular biology; the Scientist position additionally requires 2+ years of post-PhD experience.
• Demonstrated experience with mouse models and tissue processing.
• Hands-on experience with molecular cloning, genetic engineering, or genetic perturbation approaches.
• Experience designing, optimizing, and troubleshooting complex experimental workflows.
• Ability to independently design, execute, and interpret experiments.
• Strong scientific curiosity, creativity, problem-solving, communication, and collaboration skills.
• Interest in applying engineering and functional genomics approaches to complex biological systems.

Nice to have

• Scalable genetic perturbation, pooled CRISPR screens, in vivo perturbation strategies, or functional genomics experience.
• Experience studying immune cell differentiation, activation, migration, or effector function.
• Experience with mouse disease models.
• Single-cell RNA sequencing, spatial transcriptomics, or other high-dimensional genomic technologies.
• Molecular cloning, viral vector engineering, or genetic manipulation of mammalian cells.
• Advanced flow cytometry, cell sorting, or imaging techniques.
• Experience analyzing high-dimensional immunological datasets; candidates are not expected to have every listed approach.

Culture & Benefits

• Collaborative research environment spanning immunology, genomics, computational biology, and technology development.
• Research collaboration across Columbia University, The Rockefeller University, and Yale University.
• Employer match on 401(k) contributions.
• Paid time off for volunteering and funding for select family-forming benefits.
• Relocation support is available for employees who need assistance moving.

Hiring process

• Submit a cover letter describing research interests, motivations, career goals, and a significant publication or project highlighting contributions.
• Submit a full CV with major achievements and contact information for three references; letters will be requested as needed.
