Join Verana Health, a company dedicated to improving patient outcomes through data-driven research. As a Senior/Staff/Principal Backend Engineer, you will have hands-on ownership of high-throughput systems that transform complex clinical text into scalable oncology data models. Your work will directly impact patient care and clinical outcomes. You will build and optimize resilient data ingestion pipelines, own the indexing and performance tuning of our OpenSearch cluster, and implement complex OCR processing workflows. This position offers a hybrid work environment, wellness programs, financial health benefits, flexible time off, and recognition programs.

• Assumer la responsabilité de la conception, de la mise en œuvre et de l'optimisation des pipelines d'ingestion de données, en veillant à ce qu'ils soient résilients et capables de traiter des volumes élevés de données cliniques.
• Diriger l'indexation, l'interrogation et l'optimisation des performances de notre cluster OpenSearch, garantissant une découverte rapide des textes et des données à travers nos couches de données oncologiques.
• Participer activement aux revues de code et de conception, guider les décisions techniques pour les composants du système et encadrer les ingénieurs de pairs.
• 4+ years of experience with data modeling techniques for structured/unstructured datasets, strong SQL coding, and query optimization skills. Proven ability to design for and navigate both transactional (OLTP via Postgres, MySQL, etc.) and analytical (OLAP via Databricks, Snowflake, BigQuery, etc.) data systems
• 4+ years of professional experience building scalable, robust APIs, microservices, and high-volume ETL/ingestion processes
• Demonstrated experience working with OpenSearch (or Elasticsearch) for complex indexing, alongside exposure to OCR pipelines, document parsing, or natural language text processing
• Strong professional experience with Functional Programming languages (we primarily use Scala and Elixir) and/or experience in mainstream typed languages (such as Java, C#, or C++)
• Comfort using coding assistants, automated scripts, or agentic tools to streamline your daily development workflow and cut down on repetitive tasks
• Deep understanding of distributed server-side architectures, reactive principles, and cloud integrations (AWS and/or GCP), including messaging/streaming infrastructure (e.g., Amazon SQS, Kafka, and Google PubSub)
• Exceptional written and verbal communication skills, with a proven ability to collaborate cross-functionally across multiple engineering and product teams
• Real world experience with libraries within the Scala Typelevel ecosystem such as Cats, Shapeless, Circe, and Doobie among others
• Willingness to occasionally work with reactive front-end technologies (TypeScript, Angular, or React) to enhance internal project management user interfaces
• Prior experience in healthcare technology, clinical data environments, or a deep passion for improving patient outcomes in healthcare
• You do not need to match every listed expectation to apply for this position. Here at Verana, we know that diverse perspectives foster the innovation we need to be successful, and we are committed to building a team that encompasses a variety of backgrounds, experiences, and skills
