  • Build and maintain testing environments that mirror customer implementations for advanced troubleshooting and validation
  • Develop proof-of-concept solutions for complex customer use cases, demonstrating technical feasibility and best practices
  • Provide technical consultation on enterprise-level implementations and custom integrations across diverse business environments
  • Create and deliver advanced technical training for internal teams and key customers, elevating technical capabilities across the organization
  • Contribute to on-call rotations and provide expert guidance during critical incidents, ensuring rapid resolution and minimal customer impact
  • Document all customer interactions, issues, and resolutions in the support ticketing system to maintain knowledge continuity
