Senior Solution Architect Cloud & Data Platforms

Summary Architecture & Solution Design Lead endtoend architecture for hightraffic, customer-facing web applications. Design scalable microservices-based and event-driven architectures using Node.js, REST APIs, and GraphQL. Architect single-page applications (SPA) using React.js, modular component design, and optimized client-side performance. Define relational and non-relational data models optimized for high-volume OLTP transactions on PostgreSQL. Create architecture blueprints covering application layers, data flows, integration, observability, and deployment topology. Cloud Architecture on AWS Design distributed, fault-tolerant, and secure solutions using key AWS services: VPC, Subnets, NACLs, Security Groups for network isolation ALB/NLB, Auto Scaling, ECS/EKS, Lambda for compute RDS PostgreSQL, Aurora, ElastiCache for data API Gateway, CloudFront, S3 for global-scale delivery Ensure reliability, scalability, and high availability for systems processing large transaction volumes. Review and optimize cloud costs, architecture fitness, and performance. Application Performance & Scalability Design solutions with builtin load balancing, auto-scaling, queueing, caching, and failover patterns. Architect for low latency, high throughput, and predictable system behavior under peak load. Ensure appropriate use of CDN, caching layers (Redis/Memcached), and async processing. Security & Compliance Own the security architecture across application, data, and network layers: IAM design & RBAC JWT/OAuth2 authentication Data encryption in transit & rest Secure VPC patterns Work with InfoSec teams on threat modeling, vulnerability resolution, and cloud security posture. Technical Leadership Guide engineering teams on architecture patterns, design reviews, best practices, and code quality. Collaborate with product owners, UX, DevOps, and QA to ensure cohesive delivery. Mentor developers and junior architects; evangelize modern engineering and cloud-native principles.
