About the role

  • Xaira is seeking a highly motivated and experienced Senior Scientist to join our Computational Biology team with a focus on supporting large-scale single-cell perturbation screens.
  • The ideal candidate will bring deep expertise in single-cell RNA sequencing, Perturb-seq, and a proven track record of processing and integrating large-scale datasets from multiple experimental sources.
  • This position offers the opportunity to contribute to cutting-edge efforts at the intersection of functional genomics, machine learning, and disease biology.

Responsibilities

  • Own end-to-end computational analysis of Perturb-seq datasets, spanning quality control, biological interpretation, and translation of large-scale single-cell data into actionable insights for therapeutic discovery and AI/ML modeling
  • Design and implement standardized analytical frameworks for integrating Perturb-seq data across diverse experimental contexts, such as cell types, library designs, and sequencing platforms, to enable reliable cross-source analysis
  • Build and maintain scalable, production-grade bioinformatics pipelines, with an emphasis on reproducibility, modularity, and performance at the scale of large perturbation screens
  • Integrate Perturb-seq data with complementary omics modalities, including CITE-seq, ATAC-seq, spatial transcriptomics, as well as external reference datasets, to enrich biological context and support multi-modal analyses
  • Partner closely with AI/ML scientists to ensure data products meet modeling requirements, and collaborate with wet-lab scientists to translate experimental design into optimal computational workflows
  • Manage code repositories, maintain versioned and documented workflows, and uphold computational environment standards that ensure long-term pipeline reliability

Requirements

  • Demonstrated ability to integrate heterogeneous datasets from multiple sources, with a strong command of batch correction, normalization, and quality control strategies tailored to large-scale perturbation experiments
  • Strong software engineering fundamentals: proficiency in Python (numpy, pandas, scanpy, scikit-learn), fluency in Unix environments, and experience with version control and collaborative software development via GitHub.
  • Excellent analytical, organizational, written, and verbal communication skills, with the ability to thrive in fast-paced, highly collaborative environments focused on scientific innovation
  • Ph.D. in Computational Biology, Bioinformatics, Genomics, or a related quantitative field, with 5+ years of relevant industry and/or applied research experience (candidates with fewer years are also encouraged to apply and job level can be adjusted as appropriate)
  • Deep expertise in single-cell RNA sequencing analysis with substantial hands-on experience in Perturb-seq or CRISPR-based perturbation screen data, including thorough familiarity with the full processing stack from raw reads to interpretable outputs
  • Experience building and maintaining production bioinformatics workflows (e.g. Nextflow), comfort with containerized environments (Docker) and cloud computing platforms (AWS)

Skills

  • About Xaira Therapeutics
  • Xaira is an innovative biotech startup focused on leveraging AI to transform drug discovery and development.
