• API & Web Services: Perform troubleshooting for web services and APIs. Utilize tools like Postman or Hoppscotch to execute API calls and validate responses. Manage SSL/TLS certificates on servers.
• Infrastructure & DevOps: Administer Linux-based SFTP (creation, configuration, and maintenance). Provide troubleshooting support for Kubernetes and Talend environments.
• Systems & Security: Manage Identity and Access Management (IAM) via SSO methods, including SAML, Okta, and Azure Active Directory.
• Monitoring & Analysis: Analyze network metrics, disk I/O (read/write), and server performance. Utilize Power BI and Advanced Excel for data reporting and forecasting support.
• Business Domain Support: Assist in troubleshooting tools related to Supply Chain management and forecasting calculations.

Technical Requirements:

• Databases: Expert knowledge of SQL Server & SSIS.
• Programming/Scripting: Proficiency in Python and Advanced Excel (VBA/Programming).
• DevOps/Cloud: Familiarity with Kubernetes, Talend, and Azure AD.
• Operating Systems: Strong Linux administration skills (specifically SFTP).

Soft Skills & Qualifications:

• Proven experience in multi-region technical support (L1-L3).
• Exceptional analytical and complex problem-solving skills.
• Proactive and investigative approach to incident management.
• Ability to work effectively under pressure and within a team.
• Availability: Must be able to work according to the Amsterdam (CET/CEST) time zone.
