AWS Technical Architect

Responsibilities

• Define and own the cloud architecture blueprint for the mainframe modernization program — establish reference architecture, service selection standards, integration patterns, and design principles that all development workstreams must follow
• Continuously manage the configuration of all cloud environments (Dev, Test, PreProd, Prod) — identify dependencies, resolve potential conflicts, document the process, and track deployment schedules across environments
• Optimize AWS deployments for scalability, efficiency, and security — conduct regular architecture reviews to identify gaps, enforce standards, and recommend improvements across all workstreams
• Design and govern the hybrid integration architecture — define how mainframe and cloud systems communicate, establish API contract standards, messaging patterns, and data synchronization approach during parallel run
• Solve technical challenges across the program — collaborate with workstream Technical Leads, mainframe architects, and operations teams to resolve integration issues, performance bottlenecks, and deployment blockers
• Design and enforce cloud security architecture — translate mainframe security controls into cloud-native equivalents, establish IAM standards, encryption policies, network segmentation, and compliance monitoring
• Design performance and cost governance framework — establish performance baselines, monitoring standards, alerting thresholds, and cost optimization practices for all migrated workloads
• Maintain cloud architecture documentation — reference architecture diagrams, architecture decision records (ADRs), environment configuration guides, integration specs, and deployment runbooks as living documents throughout the program

Requirements

• Minimum 10+ years of software engineering with 7+ years hands-on AWS cloud architecture experience.

Skills

• Proven ability to architect, configure, and deliver enterprise-grade cloud solutions across core AWS services including EC2, Lambda, ECS/Fargate, RDS/Aurora, DynamoDB, S3, API Gateway, SQS, SNS, EventBridge, Step Functions, VPC, Direct Connect, Route 53, IAM, KMS, WAF, and Secrets Manager.
• Strong understanding of 3-tier web architectures, storage replication, backup design, and managed hosting services.
• Able to drive POCs single-handedly and migrate them to production.
• Experience comparing and positioning trade-offs between private, public, and hybrid cloud solutions on AWS.
• Strong hands-on experience designing integration architectures connecting legacy/mainframe systems with cloud-native services in hybrid environments.
• Proficient in REST API design and governance, asynchronous messaging patterns (SQS, SNS, MQ, Kafka, JMS), event-driven architecture, and data
