• Work with orchestration APIs (e.g., S3 API, Kubernetes API) and integrate with GitLab and S3 APIs for automation.
• Perform or coordinate manual UWP builds, manage ABM (Apple Business Manager) device profile administration, certificate provisioning and renewal.
• Collaborate closely with product management, infrastructure and DevOps teams to deliver a cohesive end-to-end solution; act as a technical thought-leader across disciplines.
• Preferably, manage Keycloak operations (configuration, policies, integration) and ensure identity-access workflows integrate tightly with the mobile/web stack.

Qualifications & Experience:

• Bachelor’s or Master’s degree in Computer Science, Software Engineering or equivalent degree.
• 10+ years of professional software development experience, with multiple years as a lead or principal engineer.
