The Technical Lead, Platform Engineering reports into the Director, Software Engineering. This position is responsible for leading the assessment, migration, and ongoing architecture of The Armstrong Collective's Azure cloud-native environment - spanning production workloads that need to move into a new resource group and subscription structure, and early-stage applications that require proper design and capacity planning before build. The role owns platform governance, observability, identity, and security across all four Azure subscriptions (Non-Prod, Prod, Global Shared, and Sandbox), and acts as the senior technical authority for cloud infrastructure decisions.

• Audit current production applications, resource groups, and subscription placement.
• Design and execute migration plans into the new subscription/resource-group structure, making sound, fact-based decisions on rollback and cutover procedures even when information is incomplete.
• Partner with product and engineering teams during the ideation phase to right-size architecture, capacity, and scaling strategy, effectively prioritizing competing requests to align with overall business strategy.
• Establish reusable IaC modules, reference architectures, and naming/tagging standards for consistent provisioning across subscriptions.

• Define and enforce subscription strategy and management group structure across Non-Prod, Prod, Global Shared, and Sandbox environments.
• Drive Infrastructure as Code adoption (Bicep or Terraform) across all environments, holding self and the team accountable for consistent standards.
• Design and maintain CI/CD pipelines (Azure Dev Ops or Git Hub Actions) for Functions, App Service, and Static Web Apps deployments.
• Manage cost visibility and optimization across all subscriptions, including Sandbox sprawl control, taking timely and effective action to correct issues before they elevate.

• Own observability strategy end-to-end:
  Azure Monitor, Application Insights, Log Analytics, Dashboards, and Alerts.
• Lead incident response and root cause analysis for platform-level issues, identifying underlying causes rather than symptoms, and drive postmortems that produce lasting fixes.
• Establish and maintain runbooks for migration, deployment, and recovery scenarios, keeping team members and leaders informed by sharing relevant information during incidents.

• Own identity and access strategy via Microsoft Entra  both internal workforce and external/customer-facing authentication, including B2B/B2C considerations.
• Implement network and security boundaries with Azure Front Door, Private Endpoints, and NSGs as appropriate.
• Enforce least-privilege access (RBAC) across all subscriptions, weighing risk and obstacles carefully when making access decisions that affect guest and team member data.

• Act as the senior technical voice on Dev Ops/infrastructure decisions, mentoring engineers and providing timely, specific, and constructive feedback that develops their skills.
• Communicate migration plans, tradeoffs, and platform roadmap clearly to technical and non-technical stakeholders, keeping teams and leaders informed and building trust across departments.
• Empower the team by delegating responsibility and monitoring progress, holding self and others accountable for a high level of performance.
• Champion new ideas for emerging AI workloads on Azure AI Foundry, encouraging innovation and supporting the team…
