The Senior AWS Platform Architect will lead the architectural transformation of legacy payment systems (e.g., ACH, Wire, RTP) into a cloud-native ecosystem. You will be responsible for the end-to-end migration journey—from initial discovery and dependency mapping to the implementation of event-driven architectures on AWS. Your primary objective is to modernize monolithic payment engines into resilient microservices while maintaining strict compliance with PCI DSS, ISO 20022, and regional financial regulations.

• Migration Execution: Lead the "7Rs" migration strategy (specifically Refactoring and Replatforming) to move legacy Jave and C# based payment apps to AWS.
• Strangler Fig Implementation: Gradually decompose monolithic payment systems into microservices using Amazon API Gateway and AWS Lambda to ensure zero-downtime transitions.
• Database Transformation: Migrate legacy relational databases (e.g., Oracle, SQL Server) to cloud-native alternatives like Amazon Aurora or DynamoDB using AWS Database Migration Service (DMS).
• Infrastructure as Code (IaC): Standardize environment provisioning using Terraform or AWS CDK to ensure consistent, auditable deployments across multi-region environments.

• High-Availability Architecture: Design multi-region, active-active architectures to meet stringent SLAs for real-time payment processing and disaster recovery.
• Security & Compliance: Implement "Security-by-Design" using AWS KMS for field-level encryption, AWS PrivateLink for secure third-party integrations, and AWS Artifact for PCI DSS compliance reporting.
• Event-Driven Processing: Utilize Amazon MSK (Kafka) or Amazon SQS/SNS to handle high-volume transaction streams and asynchronous settlement workflows.
• API Excellence: Develop and maintain robust RESTful APIs that integrate with modern front-ends (React) and external financial networks.

• AI-Driven Refactoring: Leverage Amazon Bedrock and GitHub Copilot to accelerate the translation of legacy business logic into modern, cloud-optimized code.
• Intelligent Observability: Implement full-stack monitoring via Amazon CloudWatch and AWS X-Ray, using AI-driven insights to detect transaction anomalies and potential fraud in real-time.
• Automated Testing: Design AI-powered testing suites to simulate complex payment edge cases and ensure regression-free migrations.

• Experience: 10+ years in financial services engineering, with a proven track record of migrating large-scale transaction systems to the cloud.
• AWS Expertise: Deep hands-on experience with EC2, EKS, Lambda, S3, and RDS.
• Payment Domain: Expert knowledge of payment rails (ACH, SWIFT, SEPA), messaging standards (ISO 20022), and clearing/settlement processes.
• Security: Strong understanding of encryption, tokenization, and PCI DSS requirements.

• IaC & CI/CD: Expert-level proficiency in Terraform and automated deployment pipelines (GitHub Actions, AWS CodePipeline).
• Data Integration: Experience with ETL platform migrations and data synchronization during hybrid-cloud phases.
• Agile Leadership: Ability to lead cross-functional squads in high-velocity, regulated environments.

• AWS Certified Solutions Architect – Professional
• AWS Certified Security – Specialty
• Experience with Agentic Commerce: Familiarity with emerging protocols for autonomous AI-driven payments.
