At Adonis, we are building a medical billing engine that automates billing workflows and improves reimbursement rates for medical providers. Billing and insurance related activities represent nearly $1 in every $7 collected by medical providers - and the high costs of collecting payments, as well as and other costs that stem from the administrative challenges within the space, unfortunately get passed down to the consumer. This is why healthcare costs continue to rise, with no end to that in sight. We’re set on helping to mitigate these challenges.

  • Familiarity with data engineering and data science development tools and libraries (i.e. Pandas, NumPy, Jupyter)
  • Familiarity with data and API engineering offerings of Amazon Web Services (i.e. Athena, Fargate, Lambda, RDS, Redshift, SageMaker, Step Functions)
  • Familiarity with data warehousing concepts
