Backend SW Engineer - Python

Remote, US · Computer/Software

We’re building tools for physicians to work as fast as they can think.Many billions of patient images are acquired each year in the U.S., and nearly all of them are reviewed and diagnosed by a radiologist. In fact, 80% of healthcare data flows through radiology IT systems, and radiologists are among healthcare’s most tech-savvy and influential physicians. But they desperately need better, user-friendly software that cuts clicks and optimizes diagnostic time. Sirona is building a modern cloud-native and AI-powered operating system (“RadOS”) that unifies radiology IT onto a single, streamlined workspace. We’re a San Francisco, CA-based software company (with employees working from all over the world) founded on a deep understanding of both the practice and business of radiology.

Senior Backend Software Engineers are responsible for the data-intensive applications and services we develop for reimagining the way doctors engage with medical images in the era of Computer Vision, NLP and Machine Learning. Software Engineers work in collaboration with our product designers, product managers and researchers/scientists to solve problems and further the application of technology in the radiology space. Their goal is to help doctors deliver the highest quality of care with the use of technology.


  • Create API solutions for internal and external web services for storing and exposing all data ingested or generated by radiologists, using test-driven development to write well-tested code
  • Build performant and reliable services and solutions to manage and transfer the large amount of data to clients
  • Collaborate with frontend and quality engineers to spec, write, test, and deploy code
  • Brainstorm features with product managers, designers, scientists and GTM team

  • Focus on company goals and trade off solutions based on cost and value
  • Run code reviews and pair programming with other engineers in the organization

  • 6+ years of professional experience with Python or similar object oriented language (Python3 preferred)
  • 5+ years API design experience
  • 5+ years Database experience (SQL or NOSQL)
  • Experience with performance and optimization problems, particularly at large scale, and a demonstrated ability to both diagnose and prevent these problems
