Job description

Duration:

24Months+ Extension

Domain Exposure:

IT/Software

Work Authorization:

• 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
• 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:
• 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.
