• Building and integrating message-based systems (event-driven, async workflows, etc.)

• Helping shape system architecture with scalability, performance, and reliability in mind

• Collaborating closely with product and front-end teams to deliver real features, not just tickets

• Improving existing systems — refactoring, optimising, and making things simpler

Profile

• Strong experience with C# / .NET CORE + in production environments

• Solid understanding of ASP.NET Core and RESTful API design

• Hands-on experience with Entity Framework Core

• Experience working with message brokers (e.g. RabbitMQ, Azure Service Bus, Kafka, etc.)

• A good grasp of scalable system design and modern back-end patterns

• Someone who cares about code quality, maintainability, and performance

Nice to have

• Experience working in SaaS products

• Cloud experience (Azure, AWS, or similar)

• Familiarity with CI/CD, containers, or microservices

• An interest in keeping up with modern .NET and back-end best practices

We offer

• You’ll work on cutting-edge tech, not legacy maintenance

• Real influence over architecture and technical decisions

• A team that values clean solutions over quick hacks

• Room to grow as the product and company scale
