• Work with API Management and Apache Kafka for integration solutions.
• Configure and manage integrations involving PostgreSQL.
• Support automation using GitHub Actions and Ansible Tower.
• Work with Azure Kubernetes Service (AKS) and Kubernetes clusters.
• Perform integration testing, troubleshooting and issue resolution.
• Work in Linux and WSL environments.
• Use tools such as Splunk, Fluent Bit and Helm for monitoring, logging and deployment.
• Communicate effectively with customer and internal technical teams.

Non-Technical Requirements

• Strong communication and stakeholder-management skills.

• Should be interested in integration engineering and customer project delivery, rather than pursuing a pure software-development or architecture role.
