  • Act as technical lead during build and migration activities, serving as escalation point for design or technical issues.
  • Lead triage and resolution of technical challenges arising during migrations.

Qualifications

  • Strong knowledge of on-premises infrastructure (compute, storage, network) and application dependencies.
  • Demonstrated ability to create architecture artefacts, diagrams, and technical documentation.
  • Deep understanding of migration strategies, security considerations, and compliance frameworks.
  • Experience working with cross-functional teams including applications, integration, and infrastructure specialists.
  • Strong communication and stakeholder management skills, with the ability to present designs and obtain approvals.
