Technical Architect AWS

AWS Application Architect

Role Summary

The AWS Application Architect will be responsible for defining and implementing cloud-native application architectures on AWS, with a strong focus on application modernization, microservices, APIs, event-driven architectures, scalability, security, performance optimization, and production-scale cloud migrations. The role requires hands-on experience in designing and delivering AWS-based solutions and leading migration initiatives from on-premises or legacy platforms to AWS.

Key Responsibilities

Application Architecture & Cloud Design

• Design cloud-native application architectures using AWS services and best practices.
• Define microservices-based solutions using AWS Lambda, ECS, EKS, API Gateway, and EventBridge.
• Architect scalable, secure, resilient, and high-performing distributed systems.
• Design RESTful APIs and service integration patterns.
• Develop modernization strategies for legacy monolithic applications.
• Create architecture diagrams, design documents, and technical standards.

AWS Migration & Modernization

• Lead application migration and modernization initiatives from on-premises, private cloud, or other cloud platforms to AWS.
• Assess source systems and define AWS target architectures.
• Design migration strategies, cutover plans, rollback procedures, and go-live activities.
• Drive application rehosting, replatforming, refactoring, or cloud-native transformations.
• Identify migration risks and mitigation strategies.
• Ensure business continuity during migration and deployment activities.

Event-Driven & Integration Architecture

• Design event-driven architectures leveraging EventBridge and AWS-native integration services.
• Develop asynchronous communication patterns between applications and microservices.
• Implement API management, governance, and security using API Gateway.

Security & Governance

• Ensure architecture aligns with AWS Well-Architected Framework principles.
• Define security controls, authentication, authorization, encryption, and compliance requirements.
• Implement secure API and microservices design patterns.
• Support governance, monitoring, audit, and observability requirements.

Performance & Reliability

• Establish performance benchmarks and scalability requirements.
• Optimize workloads for cost, performance, and operational efficiency.
• Define monitoring, logging, and alerting strategies.
• Conduct design reviews and performance assessments.
