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

As a Scientist II on Xaira's Genomics Core team within the High Throughput Biology organization, you will play a key role in generating high-quality sequencing data that powers our discovery platform and AI-driven research. You will serve as a technical leader responsible for designing, developing, optimizing, and executing next-generation sequencing (NGS) workflows, with a primary focus on Illumina sequencing platforms, including MiSeq, NextSeq, and NovaSeq. You will partner closely with Functional Genomics, Disease Biology, Automation, and Computational Biology teams to develop scalable sequencing strategies that support CRISPR-based perturbation studies, single-cell genomics, and other high-throughput discovery efforts.

The ideal candidate is an experienced experimental scientist with deep expertise in NGS library preparation, Illumina sequencing operations, and 10x Genomics workflows. This is a highly collaborative, hands-on laboratory role that requires independent scientific thinking, experimental design, and technical leadership to implement new technologies and continuously improve genomics workflows across the organization.

Responsibilities

Perform high-quality next-generation sequencing operations across Illumina platforms, including MiSeq, NextSeq, and NovaSeq. Independently design, develop, optimize, validate, and troubleshoot sequencing workflows to improve data quality, throughput, scalability, and reproducibility. Prepare and QC sequencing libraries for a variety of applications, including 10x Genomics single-cell RNA sequencing, bulk RNA sequencing, CRISPR-based sequencing assays, and targeted sequencing workflows.

Design sequencing strategies and provide technical guidance to cross-functional project teams to ensure generation of high-quality datasets that address biological and computational objectives. Partner with Functional Genomics scientists to support Perturb-seq, pooled CRISPR screening, guide sequencing, and other genomics-based discovery programs. Collaborate with Automation Engineers to develop, implement, and scale automated library preparation and sequencing workflows.

Work closely with Computational Biology teams to ensure sequencing data meets quality standards for downstream analysis and AI/ML applications. Serve as a technical subject matter expert for sequencing technologies by evaluating new methodologies, identifying experimental risks, troubleshooting complex technical challenges, and recommending scientifically sound solutions. Perform routine maintenance, calibration, and troubleshooting of sequencing instrumentation and associated laboratory equipment.

Manage sequencing sample intake, experimental tracking, reagent inventory, and laboratory documentation. Maintain accurate experimental records using electronic laboratory notebooks (ELN) and laboratory information management systems (LIMS). Evaluate and implement emerging sequencing technologies, library preparation methods, and genomics workflows to expand core capabilities.

Present technical updates, experimental findings, and workflow improvements to cross-functional project teams. Contribute to laboratory operations while ensuring compliance with safety and quality standards.
