Job Description

Team: Oncology R&D – Computational Biology / Data Science

Location: (Hybrid, US, Preferred)

Role: 

Own the design and deployment of advanced predictive models for oncology applications using sequencing data from epigenomic and genomic assays. You’ll develop, validate, and ship models that power high-resolution characterization of patient cancers using multimodal data (liquid biopsy, tissue and real-world outcomes) to provide actionable insights for patient treatment and disease monitoring.

What you’ll do:

• Modeling & research.
• Build production-grade predictive models for oncology applications (e.g. therapy response, MRD, tumor characterization).
• Develop advanced models (including deep learning-based architectures) for high dimensional and multimodal data leveraging extensive internal datasets.
• Advance self- supervised/foundation representations for genomic, DNA methylation, fragmentomics, and tissue imaging data.
• Design and execute validation plans; define performance targets and communicate results across functions to drive deployment of advanced models into production.
• Collaborate with external scientific leaders, medical affairs, laboratory directors, external collaborators to drive publications and conference presentations.

Data & engineering:

• Shape feature stores and reproducible pipelines from raw assay outputs to model-ready tensors
• Ship models via MLOps best practices (containerization, CI/CD, experiment tracking, monitoring, model cards).
• Work closely with technology development, software, product, medical, and regulatory teams to turn models into patient-impacting products.
• Author clear technical docs and present results to scientific and executive audiences.

Qualifications

• PhD (CS/EE/Bioinformatics/Statistics/Applied Math or related) or MS with equivalent experience.
• Strong ML/AI depth with hands-on work experience with deep learning (PyTorch)
• Proficiency in Python and scientific stack (sklearn); solid software engineering skills (tests, code review, version control).
• Experience with large-scale data, distributed compute, containerization (Docker) and cloud (AWS/GCP/Azure).
• Domain expertise in analysis of genomic data: cfDNA (SNVs/indels/CNAs), methylation/epigenomics, fragmentomics, RNA-seq
• Track record of publications, patents and conference presentations
