Czym będziesz się zajmować?

Your tasks:
  • Take ownership of the technical direction and support consistent delivery across the product.
  • Design and evolve microservices-based architecture with clearly defined REST endpoints.
  • Build and maintain backend services in .NET (C#) and ensure clean, stable API contracts.
  • Cooperate closely with the team working on React SPA to deliver smooth end-to-end functionality.
  • Work with PostgreSQL as the main persistence layer; support data modeling and access via Entity Framework / Repository pattern (depending on implementation).
  • Define and maintain development standards: code quality, conventions, reviews, and pragmatic documentation.
  • Support reliable delivery across environments (Dev / Staging / Prod) using Bitbucket (Git) and Bitbucket Pipelines (automated builds, tests, and deployments).
  • Work with containerized deployments using Docker, a Docker Registry, and Kubernetes deployments.
  • Work within an environment hosted on VMs in a traditional data center, with Kubernetes-based orchestration.
  • Keep engineering quality high across the product: security, maintainability, scalability, and extensibility.
  • Lead the engineering team day-to-day: guide priorities, unblock delivery, and support sound technical decisions.
