Sr. Platform Architect
Sr. Platform Architect
Contribute to building multifaceted enterprise and customized applications for a diverse and growing international client base!
RESPONSIBILITIES:
- Lead migration from monolithic systems to modular monolith and microservices using domain-driven design (DDD), bounded contexts, and service decomposition
- Architect multi-tenant, cloud-native SaaS platforms on Azure with strong tenant isolation, elastic scaling, and resource partitioning.
- Define and enforce enterprise architecture standards across .NET (C#), TypeScript, Angular, SQL Server, and Azure (SOLID, DI, async/reactive patterns).
- Design distributed systems including service orchestration, API gateways, event-driven architectures, CQRS, event sourcing, IoT/edge, and eventual consistency.
- Engineer resiliency and high availability using circuit breakers, retries, bulkheads, geo-redundancy, and disaster recovery (Azure App Services, Functions, Service Bus, Cosmos DB, Azure SQL).
- Establish performance engineering practices: SLOs mapped to SLAs, caching strategies, indexing, query optimization, load testing, and capacity planning.
- Design and implement observability platforms with OpenTelemetry, distributed tracing, structured logging, metrics, and real-time dashboards.
- Architect CI/CD and DevOps automation including IaC, automated testing (unit through end-to-end), security scanning, quality gates, and incident response playbooks.
- Lead security, compliance, and governance initiatives including multi-tenant security, OAuth2/OIDC, encryption, SSDLC, threat modeling, SOC/GDPR compliance, and architecture review boards.
- Provide technical leadership and mentorship, collaborating cross-functionally and evaluating AI/ML, analytics, and developer productivity tools to drive innovation.
