• Proven ability to design solutions, solve complex problems independently, and translate business requirements into technical architectures
• Zendesk Analytics (analytics/reporting) expertise, including custom dashboard development and data modeling

• Zendesk Certified Administrator or equivalent certification
• Experience operating large-scale Zendesk environments (500+ agents, multi-brand, multi-product) with strict performance and reliability expectations
• Experience with implementations, migrations, platform consolidations, or large-scale configuration changes
• Experience leading QA/UAT strategies, including test planning, regression testing, deployment planning, and rollback procedures
