About The Position

We are seeking an exceptional and highly motivated Senior Scientist to architect and lead our efforts in in vivo CRISPR screening. In this pivotal role, you will be instrumental in advancing our mission to pioneer biological discoveries through high-throughput functional genomics. You will lead strategic initiatives that push the technical boundaries of genetic screening at the intersection of mouse models, data science, AI/ML, and translational biology. This position is ideal for a seasoned discovery scientist who excels at translating data-driven insights into therapeutic research while balancing strategic leadership with advanced individual technical contributions.

Requirements

Ph.D. in Molecular Biology, Genetics, Pharmacology, or a related field, with 4+ years of postdoctoral or industry experience.
Strong experience with in vivo genetic manipulation (e.g., lentiviral or AAV delivery in mice), mouse handling, colony management, and in vivo experimentation, with an understanding of animal welfare and regulatory standards.
Familiarity with perturb-seq and single-cell genomics.
Ability to troubleshoot technical issues, adapt to new protocols, and optimize methodologies for in vivo applications.
Excellent written and verbal communication skills, with a track record of presenting complex scientific results to multidisciplinary teams.
Demonstrated success in working collaboratively in a fast-paced, team-oriented environment.

Nice To Haves

Familiarity with spatial omics and interest in exploring new readout methods.
Experience in data analysis using Python or R.
Experience in in vivo CRISPR screening.

Responsibilities

Develop, implement and scale high-throughput CRISPR-based screening protocols in mouse models to uncover genotype-phenotype relationships at scale.
Drive continuous innovation in experimental workflows and screening methodologies.
Partner with computational biology, AI/ML, and drug discovery teams to analyze, interpret, visualize, and communicate findings from large-scale functional genomics datasets.
Identify and resolve challenges in data generation, including assay reproducibility, sample throughput, and quality control.
Independently manage multiple projects, ensuring timely delivery of high-quality data and adherence to team goals.
Maintain accurate records of experiments, protocols, and findings, contributing to internal and external scientific presentations.
Mentor junior staff and research associates, fostering their scientific and professional growth through active technical guidance and career development.
Lead strategic project planning and long-term program development initiatives to ensure alignment with broader therapeutic discovery goals.
Independently drive and oversee complex cross-functional collaborations with internal and external partners to accelerate program milestones.
