The posting

About Xaira Therapeutics

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.

About the Role

We are seeking an experienced Scientist to lead our efforts in organoid model development for functional genomics and CRISPR screening. In this role, you will help advance our mission to pioneer biological discoveries through high-throughput functional genomics, working at the intersection of organoid biology, data science, AI/ML, and translational research. This position is ideal for a seasoned discovery scientist who can balance strategic leadership with hands-on technical contributions.

Key Responsibilities

  • Develop, implement, and scale organoid-based model systems to support high-throughput CRISPR screening and uncover genotype-phenotype relationships at scale.
  • Establish and optimize protocols for organoid culture, maintenance, and characterization across relevant tissue types, ensuring robustness and reproducibility for screening applications.
  • Drive continuous innovation in experimental workflows and screening methodologies within organoid systems.
  • 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.

Requirements

  • Ph.D. in Molecular Biology, Genetics, Cell Biology, or a related field with 0-4 years of industry or postdoctoral research experience.
  • Strong hands-on experience developing and maintaining organoid model systems (e.g., patient-derived, iPSC-derived, or tissue-derived organoids), including culture optimization, passaging, and characterization.
  • Experience with CRISPR-based genetic perturbation approaches (e.g., lentiviral or AAV delivery) in complex 3D or organoid model systems.
  • Familiarity with methods for adapting organoid systems to high-throughput screening formats, including relevant automation or miniaturization approaches.
  • Ability to troubleshoot technical issues, adapt to new protocols, and optimize methodologies for organoid-based 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.

Preferred Qualifications

  • Familiarity with perturb-seq, single-cell genomics, or spatial omics, and interest in exploring new readout methods.
  • Experience in data analysis using Python or R.
  • Experience in in vivo or in vitro CRISPR screening more broadly, beyond organoid systems.

Compensation

We offer a competitive compensation and benefits package, seeking to provide an open, flexible, and friendly work environment to empower employees and provide them with a platform to develop their long-term careers. A Summary of Benefits is available for all applicants. We offer a competitive package that includes base salary, bonus, and equity.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
