  • Working closely with developers, testers, product managers and operations teams
  • Contributing to Agile delivery and DevOps processes

What we are looking for

You should have commercial experience with:

  • C# and .NET
  • ASP.NET MVC or Web API
  • SQL Server or PostgreSQL
  • Unit testing
  • Backend application development
  • Debugging and production support

Experience with the following would be particularly useful:

  • RabbitMQ, Kafka, Azure Service Bus or similar messaging technologies
  • Event-driven architecture
  • Multi-threading, concurrency or asynchronous processing
  • Distributed systems
  • CI/CD
  • Docker
  • Cloud platforms
  • Cassandra or other NoSQL databases
  • Real-time data or industrial communication protocols

Oil and gas experience is not required. Candidates from SaaS, FinTech, telecoms, IoT, industrial software or other complex backend environments are encouraged to apply.

Salary

  • Mid-level: £40,000 to £55,000
  • Senior: £55,000 to £65,000
