Hi, we're Oscar. We're hiring a Senior Software Engineer, Backend to join our Engineering team.

Oscar is the first health insurance company built around a full stack technology platform and a focus on serving our members. We started Oscar in 2012 to create the kind of health insurance company we would want for ourselves—one that behaves like a doctor in the family.

You will work with partners, product managers, and designers to solve challenging problems.

  • Make steady, well-paced progress without requiring frequent significant feedback from more senior engineers.
  • Compliance with all applicable laws and regulations
  • Other duties as assigned
Qualifications
  • 5+ years of professional software engineering experience, working with a variety of technologies, and have increasingly impactful accomplishments
  • Experience proposing, experimenting, and iterating, whether it be a new shiny technology or an arcane, ill-conceived data structure; our company may be new, but the health industry isn't!
  • Experience with technical contributions, improving the quality of what you create, and are excited to build fault-tolerant, and scalable software systems.
  • Demonstrates solid understanding of the practical application of CS concepts within their team.
  • Consistently writes stable, correct, and maintainable code with little oversight; writes modular, adaptable code with guidance.
Bonus Points
  • Experience supporting libraries and writing in Python and Golang.
  • Experience owning observability stack tooling, e.g. Grafana, BigQuery, Kubernetes.
  • Experience working in data and engineering tooling, e.g. discovery libraries, data replication, data transfer tools, authentication, authorization libraries.
