Backend Developer (.NET)

A bit about us:

Customers use our platform to manage equipment rentals: reservations, check-out, damage photos, invoicing and QuickBooks sync. The product is a mobile app plus a React web dashboard, with a Python and PostgreSQL backend on AWS.

We are adding a Backend Developer (.NET) to our Payments team. You'll work mostly on server-side code: services, queues, databases and the glue between them. Little to no frontend work. Our team is spread across 12 countries. Headquarters is in Auburn. Contract role, full-time hours, paid in USD at the end of each month. You will need at least 4 hours of overlap with US Central time.

Your responsibilities:

• Reduce cloud costs by right-sizing services and cleaning up unused resources
• Secure endpoints with OAuth 2.0, JWT validation and proper input checks
• Model data and write migrations for PostgreSQL, MySQL or DynamoDB
• Review code for correctness, performance and failure handling

Who you are:

• 2+ years of backend development experience in a production environment
