About the Role

Join a high-impact strategic program with a globally renowned consultancy, delivering a next-generation Fleet Management and Autonomy solution for a major international mining client. This role places you at the heart of innovation—building advanced dispatching systems, high-precision machine guidance, and autonomous vehicle control technologies that will transform large-scale mining operations.

As a Senior Back-End Developer, you’ll work within a cross-functional agile squad to design and develop scalable, high-performance backend services spanning control systems, data centres, and onboard platforms.

• Lead the technical delivery of complex features from design through to deployment.
• Influence system architecture and drive engineering best practices through participation in design reviews.
• Ensure high code quality and maintainability via automated testing, peer code reviews, refactoring, and clear documentation.
• Continuously improve system reliability, observability, and performance.
• Mentor and support junior engineers within the development squad.
• Collaborate with Domain Engineers to ensure seamless integration with shared platforms, frameworks, and enterprise standards.
• Proactively surface and manage technical risks and architectural gaps early in the delivery lifecycle.

Technical Requirements

• Minimum 5 years of experience in backend software development.
• Strong skills in C#, .NET Core, Entity Framework, and RabbitMQ.
• Solid experience with SQL Server and deep understanding of relational database design and performance.
• Hands-on experience with microservices architectures and containerisation technologies(Docker, Kubernetes).
• Comfortable working in Linux-based environments.
• Familiarity with unit testing frameworks, CI/CD pipelines, and modern DevOps practices.
• Bonus: Exposure to Akka.NET or actor-based programming models.
