The Challenge:

• Design and build high-performance Java backend systems from architecture to production;
• Work with event-driven architectures using Kafka at scale;
• Manage and evolve cloud infrastructure on Azure with Terraform;
• Develop and maintain GraphQL Federation layers across distributed services;
• Orchestrate containerised workloads with Kubernetes;
• Champion testing culture through TDD, integration testing, and shift-left practices;
• Drive CI/CD pipelines and contribute to engineering best practices.

What you bring to the table:

• 5+ years of experience in software development with a strong Java backend focus;
• Solid command of OOP principles and design patterns;
• Hands-on experience with Terraform, Kubernetes, Kafka, and Azure;
• Strong CI/CD and Git practices;
• Excellent problem-solving skills and a collaborative mindset;
