Our Client

About the Role
Our client is looking for a Senior Backend Developer to take real ownership of backend systems in a high-throughput, multi-tenant environment. This is a hands-on role at the core of a demanding production system, you'll work across service design, concurrency, database architecture, and Shopify integrations while contributing to an ongoing infrastructure migration from Railway to Azure.
Their current backend is primarily Go and TypeScript, but they value engineering fundamentals over language loyalty. If you've built reliable, scalable systems in Go, Python, Node.js, Java, Kotlin, or Rust and you understand what it takes to keep a high-throughput distributed system running, we want to talk to you.
Key Responsibilities

- Manage and optimize PostgreSQL databases, including connection pooling and query performance
- Contribute to the migration of infrastructure from Railway to Azure

Nice to Have
