- Experience with distributed architectures and patterns such as Saga and Outbox, along with messaging technologies such as RabbitMQ or Pulsar.
- Proficiency in Java 17+ and modern language features such as Records, Pattern Matching, and Virtual Threads.
- Experience with development tools and libraries such as Lombok and MapStruct.
- Knowledge of cloud computing platforms such as AWS or GCP, as well as Docker and Kubernetes.
- Familiarity with observability technologies such as OpenTelemetry and Micrometer.
- Experience with structured logging and monitoring platforms such as ELK and Grafana Loki.
- Strong problem-solving skills, technical curiosity, and the ability to collaborate effectively across engineering and DevOps teams.
Benefits:
- Opportunity to work with modern technologies across Artificial Intelligence, Generative AI, cloud computing, distributed systems, and digital platforms.
- Exposure to challenging, technology-intensive projects and opportunities to work with advanced engineering practices.
- Access to AI-driven tools and emerging technologies to support innovation and software development.
- Professional growth opportunities through continuous exposure to evolving technology trends and industry practices.
- A collaborative, knowledge-sharing environment designed to support technical and career development.
- Opportunity to work alongside experienced technology professionals and contribute to innovative digital solutions.
- Access to a global technology ecosystem with opportunities to develop expertise in emerging technologies.
- A culture that encourages continuous learning, innovation, and professional growth.
