Fathom is on a mission to use AI to understand and structure the world's medical data, starting by making sense of the terabytes of clinician notes contained within the electronic health records of the world's largest health systems. Our deep learning engine automates the translation of patient records into the billing codes used for healthcare provider reimbursement, a process today that costs hospitals in the US $15B+ annually and tens of billions more in errors and denied claims. We are a venture-backed company that completed a Series B round of financing for $46M in late 2022.
We are looking for a Senior Software Engineer, Backend to work on data products that drive the core of our business.

Your role and responsibilities will include:
Developing data infrastructure to ingest, sanitize and normalize a broad range of medical data, such as electronics health records, journals, established medical ontologies, crowd-sourced labelling and other human inputs
Building performant and expressive interfaces to the data
Creating infrastructure to help us not only scale up data ingest, but large-scale cloud-based machine learning We are looking for a teammate with:
5+ years of development experience in a company/production setting
Experience building data pipelines from disparate sources
Hands-on experience building and scaling up compute clusters
A solid understanding of databases and large-scale data processing frameworks like Hadoop or Spark and the ability to evaluate which tools to use on the job
A unique combination of creative and analytic skills apt of designing a system capable of pulling together, training, and testing dozens of data sources under a unified ontology Bonus points if you have:
Know-how of developing systems to do or support machine learning, including experience working with NLP toolkits like Stanford CoreNLP, OpenNLP, and/or Python's NLTK
Expertise with wrangling healthcare data and/or HIPAA
Experience with managing large-scale data labelling and acquisition, through tools such as through Amazon Turk or DeepDive Salary range:
