Role summary

Septerna seeks an experienced scientific leader with AI/ML expertise to head its Data Science function. This visionary, hands-on role involves implementing advanced machine learning and statistical methods to utilize proprietary GPCR structural and assay data for small-molecule drug discovery. The leader will create and execute a strategy for leveraging internal data, collaborating with cross-functional research teams to accelerate discovery. Key responsibilities include leading the Data Science team, developing roadmaps for AI/ML applications, integrating emerging technologies, overseeing analysis pipelines (DEL, HTS, assay data), and advancing ML-QSAR models. The role also requires refining data engineering and cloud infrastructure, establishing best practices for data curation and model validation, and demonstrating leadership in applying ML to scientific problems. Expertise in scientific machine learning, cloud computing, and MLOps is essential.

Septerna is a biotechnology company based in South San Francisco, CA on a mission to develop life-changing medicines for patients with the vision to become the industry-leading G protein-coupled receptor (GPCR)-focused drug discovery company. The company’s Native Complex Platform™ recapitulates GPCRs with their native structure, function, and dynamics outside of the cellular context. This approach enables novel access to modern structural and screening technologies used in industrial-scale drug discovery for the entire class of GPCRs. Septerna has an emerging pipeline of GPCR-targeted small molecule programs, many in the Endocrinology space, with potential for growth to target many GPCRs that have been undruggable and unexploited to date.

We are excited to expand our multidisciplinary team of individuals focused on creating revolutionary medicines to address the unmet needs of patients. At Septerna we strive to embrace diversity of thought, expertise, and background through collaboration. To join our ambitious team, be prepared to bring your real self to work every day; grow and learn from a talented team of drug hunters, scientists, and business professionals; and contribute your passion, creativity, and energy to accomplish our mission. We share a fearless pursuit of ground-breaking innovations and cultivate an environment where our employees succeed by learning from each other and working as a team.

We are committed to the development of meaningful therapeutics for patients with indications of high unmet need. This is a tremendous opportunity to work with talented individuals on the frontlines of therapeutic discovery and development. You will directly help move therapies through preclinical research, positioning them for success in the clinic. The successful candidate will add their passion, unique talents, and expertise to a dynamic team motivated to discover new disease-modifying therapeutics for patients in a fast-paced environment.

This is a visionary, hands-on leadership role that requires a strong understanding of our internal data assets, modern drug discovery practices, and advanced computational methods. This leader will create and execute a strategy for fully leveraging Septerna’s proprietary data, while collaborating closely with Computational Chemistry, Structural Biology, and other cross-functional research teams to accelerate hypothesis generation and advance scientific discovery.

The ideal candidate brings technical depth in machine learning, practical expertise in statistics, a strong scientific foundation in drug discovery, and the leadership capability to build a high-impact function in a fast-moving environment.

Key Responsibilities

  • Lead Septerna’s Data Science team, providing technical direction, developing team capabilities, and integrating and prioritizing projects, with a primary focus on machine-learning applications.
  • Develop and execute a roadmap for implementing state-of-the-art AI/ML approaches that use Septerna’s GPCR structural data to discover and refine novel chemical matter.
  • Identify productive emerging technologies; lead their integration into Septerna’s computational stack through internal development, strategic partnerships, or a combination of both.
  • Oversee and extend analysis pipelines, including DNA-encoded library (DEL), high-throughput screening (HTS), and assay-data workflows, and identify opportunities to advance Data Science as part of the broader Platform development team.
  • Advance and support ML-QSAR models leveraging internal and external assay and ADMET data to impact the efficiency of DMTA cycles and as a basis for generative chemistry workflows.
  • Refine data-engineering and cloud-infrastructure requirements while establishing best practices for data curation and model validation.

    • Required Qualifications

  • PhD in computational biology, computational chemistry, or a degree in computer science, applied mathematics or statistics that was focused on modeling biological systems.
  • Minimum of 10+ years of relevant industry experience including application of machine learning to diverse scientific problems.
  • Demonstrated leadership in machine learning for drug discovery, with a track record of building and applying predictive models to real-world, noisy, and multimodal scientific datasets.
  • Experience applying co-folding or hybrid models to enable productive ligand pose prediction ideally on membrane proteins and flexible protein classes.
  • Previous work transfer learning or fine-tuning foundation models and using appropriate metrics to demonstrate model performance improvements and characterize applicability domain.
  • Experience leading teams and serving as the senior technical lead of cross functional initiatives with track record of applying technical insight and scientific judgement to guide research strategy.

    • Technical and Platform Requirements

  • Expertise in scientific machine-learning and drug discovery dependencies such as PyTorch, scikit-learn, numpy, pandas, pyarrow, and RDKit.
  • Deep knowledge of modern machine-learning and statistical methods, including gradient boosting decision trees (XGBoost, LGBM), graph neural networks (GNN/D-MPNN), transformers, generative modeling, active learning, and Bayesian optimization.
  • Extensive experience with cloud and distributed computing environments, including AWS, GCP, or Azure, as well as building and maintaining containerized machine-learning workflows.
  • A strong track record in MLOps and in partnering with software and platform engineering teams to define fit-for-purpose infrastructure for scientific applications.
