We are adding a Junior Backend Developer, Kotlin to our operations team. The operations team owns services that process several million requests a day.

This is a long-term contractor role, paid monthly in USD. Core hours overlap with US Central time, 9:00 AM to 1:00 PM CT.

• Containerize services with Docker and deploy them to Kubernetes or ECS.
• Tune slow queries, add indexes and read query plans.
• Instrument services with metrics, structured logs and OpenTelemetry traces.
• Document APIs in OpenAPI and keep the docs current.
• Design and build REST and gRPC APIs in Go, Java or Python.
• Add caching with Redis where it actually helps, and remove it where it doesn't.
• Review code for correctness, performance and failure handling.

Minimum qualifications

• 1-2 years of backend development experience in a production environment.
• Strong SQL and relational data modelling skills.
• Proficiency in at least one of Go, Java, Kotlin, Python, C# or Node.js.
