Qualifications

• At least 7 years experience building production software, 3+ years as a hands-on architect or principal engineer.
• 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).
• Solid understanding of architecture trade-offs, DDD, integration patterns, and secure design.
• Preferred: Databricks / Data Lake, Tableau or PowerBI; Azure Solutions Architect Expert, DevOps Engineer Expert.

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.
