* 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;
