Lead Bioinformatician (cfDNA Algorithms and Pipelines)

Natera is seeking a Lead Bioinformatician to advance the algorithmic foundations of our diagnostic assays supporting Women’s and Organ health. This is an individual contributor role. You will bring the genomics expertise the team needs to pull reliable signals out of sequencing data that is often ambiguous.

You will build the methodological foundations and implement the algorithms needed for detecting variants (SNVs, Indels, CNVs, SVs) that are hard to call accurately in low fraction (fetal, donor cfDNA) samples. The ideal candidate will have deep experience in algorithmic genomics, strong programming skills, and a passion for developing scalable, clinically impactful computational tools.

Panel and Assay Science: Provide genomics algorithm insights to our expanded panel roadmap, including which genes are worth considering and why, working with Product, the Laboratory Directors, and Research, who own that decision jointly. Help define the approach for analytically difficult genes and assay edge cases, and weigh what is scientifically defensible against what is technically possible.

Caller Strategy and Method Development: Define the computational strategy for new targeted and special-purpose callers. Help decide when a new caller is justified and when an existing method should be extended instead. Prototype and benchmark new methods, and work with the engineering team to get methods into production.

Scientific Investigation and Escalation: Serve as a genomics consultant on complex production escalations, separating biological causes from analytical and pipeline ones. Recognize when a result looks suspicious because of where the reads came from and not because the analysis went wrong. Turn one-off investigations into durable rules and design changes that reduce repeat work.

Data Quality and Cross-functional Partnership: Act as bioinformatics liaison with Variant Management, Reporting, and Laboratory Operations on data quality, variant representation, and system integration. Provide the scientific rationale that the accountable Quality and Laboratory functions rely on when they decide a method is ready to deploy.

Ways of Working: Help define what correct looks like for AI-assisted scientific investigation, for example what an agent may and may not conclude from a region-level finding without a human signing off. We do not screen for prior experience with these tools, and many strong candidates come from environments where they were restricted; we provide the tooling and the ramp time.

• Contributed to the scientific and bioinformatics rationale of product roadmaps.

• Deployment-readiness criteria for new analysis methods exist and are in use, and you have contributed to at least one new or extended caller yourself.

• You take on the bioinformatics aspects inside complex production investigations without waiting to be assigned them.

• Other groups know they can bring genomics questions about our assays to you.

• Degree in Bioinformatics, Computational Biology, Bioinformatics, Human Genetics, or a related field. We do not require a Ph.D. or M.S.: equivalent depth built through work counts fully.

• 4+ years analyzing short-read sequencing data for screening or diagnostic applications, preferably in a regulated, accredited, or production-adjacent setting. We count relevant experience from the point your work became substantially independent, however you got there.

• Experience contributing to the bioinformatics workflows behind a sequencing assay or panel.
