Country: United States

US Locations: Tampa, Hermitage, Nashville, Cincinnati, Indianapolis, Kansas City, San Antonio, St. Louis

Deloitte Global is the engine of the Deloitte network. Our professionals reach across disciplines and borders to develop and lead global initiatives. We deliver strategic programs and services that unite our organization.

We're hiring a hands-on Solution Architect who will design and evolve both the high-level and detailed architecture for new product features while supporting and improving existing capabilities. You'll lead with code and architecture─pairing with engineers, producing reference implementations, and ensuring robust, scalable, cost-efficient solutions in Azure using .NET/C#, React/Node/TypeScript, and modern data-processing patterns.

Primary Responsibilities

• Define HLD/LLD for new features and complex refactors (context & container diagrams, sequence diagrams, deployment views, data flows).
• Author and steward Architecture Decision Records (ADRs), validate decisions via experiments and load tests.
• Build reference implementations/PoCs in C#/.NET and React/Node to de-risk patterns, performance, and operability.
• Review and merge PRs, provide actionable feedback, and pair with engineers on tricky problems.
• Design event-driven and streaming architectures leveraging Azure Service Bus, Functions, App Services, AKS, and API Management.
• Engineer for high throughput and low latency: concurrency, async I/O, caching (Redis), partitioning, idempotency, back-pressure, and circuit-breaking.
• Model data across Azure SQL and Cosmos DB, including indexing, partitioning, consistency, and query optimization.
• Guide modern React (TypeScript) architecture: component design, state management, performance profiling, accessibility, SSR/BFF patterns with Node.js.
• Ensure clean API contracts (REST/JSON, GraphQL where appropriate), schema governance, and sound error semantics.
• Drive observability: distributed tracing (OpenTelemetry), metrics and logs (App Insights), and actionable dashboards/alerts.
• Bake in security: OIDC/OAuth2 (Entra ID), secrets management (Key Vault), OWASP ASVS, threat modeling.
• Define SLOs/SLIs, error budgets, and ensure production readiness─on-call participation and RCA for major incidents.
• Champion CI/CD (Azure DevOps or GitHub Actions), IaC (Bicep/Terraform), repeatable environments, and golden paths/templates.
• Optimize for cost and performance (FinOps): right-sizing compute, data tiering, caching, and workload scheduling

While this position is posted in the US, we can only accept applications from those performing aDeloitte Global (DTTS) role at this time.

• Deep proficiency in C#/.NET (7/8), ASP.NET Core, WebAPI, async/concurrency, performance profiling.
• Strong React (18+) + TypeScript and Node.js experience, testing with Jest/Cypress.
• Proven delivery of data-processing-intensive systems (batch/stream, resiliency, throughput, cost).
