Job Description: Senior Solution Architect (AWS | React.js | Node.js | PostgreSQL | Modern Web Apps)
Key Responsibilities
Architecture & Solution Design
Lead end‑to‑end architecture for high‑traffic, 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 built‑in 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.
DevOps, Observability & Delivery
Partner with DevOps to design CI/CD pipelines, IaC (Terraform/CloudFormation), and automated release processes.
Ensure full-stack observability using CloudWatch, X-Ray, ELK/Datadog/New Relic.
Champion SRE practices—error budgets, performance baselines, incident readiness.
