We are looking for Middle .NET Engineers to join a long-term project for one of our existing clients. You will focus on building and evolving secure, cloud-based .NET applications and REST APIs, and take part in deployment and production support activities.

  • Solid commercial experience delivering production applications and APIs with C# and supported .NET versions.
  • Good understanding of object-oriented design, REST APIs and web standards, with awareness of security, resilience and maintainability.
  • Hands-on experience deploying, debugging and troubleshooting web applications and APIs, ideally in a cloud environment.
  • Experience writing automated tests and using Git to collaborate on software changes.
  • Working knowledge of SQL and relational databases for developing and diagnosing application data access.
  • Ability to investigate problems, identify root causes and deliver reliable fixes.
  • English at Upper-Intermediate level or higher and experience collaborating with distributed teams.

Nice-to-have

  • Experience working in an Agile delivery environment or developing N-tier solutions.
  • Exposure to microservices, message brokers such as RabbitMQ, or gRPC.
  • Experience with AWS or Azure, or container platforms such as OpenShift or Kubernetes.

The impact you'll create

  • Develop and enhance secure, maintainable .NET applications and REST APIs for new and existing solutions.
  • Contribute to cloud-based service design and integrations, using messaging or gRPC where appropriate.
  • Write automated tests, take part in code reviews and document technical decisions.
  • Deploy, monitor and troubleshoot applications in cloud environments, and help resolve production incidents.
  • Work with distributed engineering and business teams across EMEA to turn requirements into practical solutions.
