Small business owners and physicians make up a large share of the client list. Everyone here is salaried. Nobody is paid on product sales. We have been family run since 1958.

• Review code for correctness, performance and failure handling.

You'll need:

• 7+ years of backend development experience in a production environment.
• Comfort reading logs, metrics and traces to debug problems in production.
• Hands-on experience with AWS, GCP or Azure services.
• Experience designing and versioning HTTP APIs.
