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.\nAbout the Role\n We are seeking a Senior Software Engineer to join our Platform team to design, build, and deploy the AI infrastructure that powers our world-class research team. In this role, you’ll collaborate closely with AI Scientists and other engineers to enable the effective use of thousands of GPUs for training and inferencing cutting-edge biological foundation models.\nThis role spans a range of problems and skillsets, ranging from MLOps of cutting-edge GPU clusters, to backend engineering of control plane APIs. Our ideal candidate has an opinion about slurm or kubernetes for model training, cares about maximizing bandwidth from the storage subsystems to the GPU, and can build the API paved path for submitting training jobs that are able to dispatch to multiple clusters.\nWhat You Will Do\nDevelop and improve our model training system, responsible for dispatching distributed training jobs to clusters across multiple clouds.\nDeploy storage subsystems that improve dataset management and throughput for training datasets.\nBuild evaluation infrastructure that enables easy execution and tracking.\nBuild base tooling for integrating model training with other internal infrastructure, such as telemetry, experiment tracking, and checkpointing.\nPrior experience with biology is not required - we will teach what you need to know. You’ll get to go in the lab, and for our ideal candidate, this should be a perk, not a chore!\nPreferred Skills and Qualifications\nDegree in Computer Science, Machine Learning, Computational Biology, or a related field.\n5+ years of industry experience building and deploying ML systems in production environments\nExperience leading technical projects and driving cross-functional execution.\nStrong programming skills in Python.\nExperience with infrastructure/ops tools such as Terraform, Ansible.\nExperience with deep learning frameworks such as Torch, Jax.\nSolid understanding of machine learning\nExperience with the infrastructure needs of large-scale model training.\nStrong problem-solving skills and ability to work in a collaborative, multidisciplinary environment.\nCompensation\nWe 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.
