Platform & Infrastructure Management: Deploy and manage containerized applications using OpenShift and Kubernetes, leveraging cloud services and modern CI/CD DevOps practices.

Business Translation & Collaboration: Collaborate with cross-functional technical teams and business stakeholders to translate business needs into technical specifications and resolve integration, governance, and data-ownership challenges.

Data Reliability & Quality Assurance: Implement fault-tolerant patterns (retries, DLQs, data consistency), design data schemas/ERDs, author test plans, and track defects to maintain solution integrity and high delivery standards.

Security & Compliance: Ensure all application designs and data schemas comply with legislative standards, corporate policies, security protocols, and privacy frameworks.

Contract Duration: 6 months.

Enterprise Integration: Advanced experience with Apache Camel, MuleSoft, Enterprise Java, REST APIs, and data transformation formats (JSON/XML). Strong background in API-led connectivity and patterns.

Cloud & Containers: Expertise in OpenShift/Kubernetes for containerized deployments; experience with AWS services (Lambda, SQS, S3) is an asset.

Data & Databases: Strong SQL skills, data modeling experience, and deep knowledge of fault-tolerant patterns (DLQs, retries, data monitoring).

DevOps & Process: Proficiency with source control, automated testing, CI/CD pipelines, and Infrastructure-as-Code.
