What will your typical day look like? 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
