About The Position

Our client is seeking a remote Senior AWS Migration Architect to lead the design and implementation of complex cloud migration and modernization initiatives across enterprise environments. This is a senior, hands-on architecture role for someone who has successfully planned and executed large-scale migrations into AWS. You will assess existing environments, develop migration strategies and wave plans, design secure and scalable target architectures, and guide workloads from discovery through migration, modernization, and operational transition. The right candidate brings deep AWS expertise along with strong knowledge of application migration, infrastructure, networking, security, automation, and cloud financial optimization. You should be comfortable serving as a technical authority while also working directly with customers, development teams, operations teams, and other stakeholders to turn business and technical requirements into practical cloud solutions. Success in this role means delivering secure, resilient, cost-effective AWS environments while reducing migration risk, improving operational performance, and creating a clear path for continued cloud modernization.
