Enterprise Systems Architect (Google Workspace Migration)

Enterprise Systems Architect (Google Workspace Migration)

Location: 100% Remote

Role Summary

We are seeking a seasoned Enterprise Systems Architect to serve as the principal technical authority and leader for a critical, large-scale digital transformation: migrating our entire enterprise infrastructure from Microsoft 365 to Google Workspace. In this role, you will bridge the gap between high-level business strategy and deep technical execution. You will be responsible for defining the comprehensive migration strategy, designing the target-state Google Workspace architecture, and establishing a multi-phase implementation roadmap. As the technical lead, you will guide engineering teams, manage risk, ensure data integrity, and minimize operational downtime for our global workforce.

Key Responsibilities

Technical Leadership & Strategy

• Roadmap Development: Architect and document the end-to-end technical strategy, migration discovery patterns, and sequencing roadmap for a seamless cutover.
• Technical Governance: Serve as the subject matter expert (SME) and final escalation point for complex technical challenges bridging Microsoft 365 and Google Workspace ecosystems.
• Stakeholder Alignment: Translate complex architectural decisions into actionable business insights for executive leadership, while providing clear, structured guidance to implementation teams.

Architecture & Migration Execution

• Infrastructure Design: Design and configure a secure, scalable Google Workspace tenant architecture, encompassing organizational units (OUs), core apps (Gmail, Drive, Docs, Calendar, Meet), and administrative privileges.
• Data & Service Migration: Lead the architectural planning for migrating large-scale mailboxes, complex calendar structures, distribution groups, and massive document stores (moving from SharePoint Online and OneDrive to Google Drive).
• Tooling Selection: Evaluate, test, and select enterprise-grade migration tools (e.g., Google Workspace Migrate, CloudM, BitTitan MigrationWiz) to automate and secure data transfer.
• Coexistence Strategy: Design and manage temporary coexistence environments (mail routing, free/busy calendar lookups, and dual-delivery) to maintain seamless business operations during the transition phase.

Identity, Security & Compliance

• Identity & Access Management (IAM): Design and implement secure authentication workflows, identity federation, and user provisioning bridging Microsoft Entra ID (formerly Azure AD) and Google Cloud Identity.
• Security & Data Loss Prevention (DLP): Establish robust security postures within the Google Admin Console, configuring Google Vault for eDiscovery, endpoint management (MDM), and custom DLP policies to align with enterprise compliance frameworks.
• Mail Security & Routing: Oversee the updates and validation of crucial DNS configurations, including MX records, SPF, DKIM, and DMARC policies to prevent delivery interruptions or security vulnerabilities.

Required Qualifications & Experience

Experience

• Enterprise Architecture: Minimum of 8+ years of progressive IT architecture and engineering experience in complex, large-scale enterprise environments ($>5,000+ users).
• Proven Migration Leadership: Must have successfully led at least one comprehensive, large-scale enterprise migration from Microsoft 365 to Google Workspace from inception to post-migration validation.
• Cross-Platform Expertise: Deep, authoritative technical knowledge of both the Microsoft 365 ecosystem (Exchange Online, SharePoint, OneDrive, Teams, Entra ID) and the Google Workspace suite.

Skills & Knowledge

• Hands-on experience configuring and scaling native and third-party enterprise migration platforms.
• Advanced understanding of cloud networking, identity management (SAML, OIDC, SSO), and email infrastructure.
• Strong scripting and automation capabilities (e.g., using Google Apps Script, Python, or GAM) to handle bulk admin tasks and custom migration logic.
• Outstanding leadership and communication skills, with a proven ability to manage change and handle the cultural shift associated with moving productivity suites.

Education

• Bachelor's degree in Computer Science, Information Technology, System Engineering, or equivalent practical experience.

Preferred Certifications

• Google Cloud Certified: Professional Google Workspace Administrator
• Google Cloud Certified: Professional Cloud Architect
• Microsoft 365 Certified: Enterprise Administrator Expert
