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;
