About the role

  • Design and maintain a cloud-native architecture using AWS services (Lambda, API Gateway, DynamoDB, EKS, CloudFront) to support high-volume transaction processing.
  • Lead the architectural design for integrating our commerce engine with third-party systems, including ERPs, PIMs, OMS (Order Management), and Payment Gateways (Stripe/Adyen/PayPal).
  • Architect solutions for 'bursty' traffic (e.g., product drops, holiday sales), utilizing auto-scaling, caching strategies (Redis/ElastiCache), and CDNs.
  • Ensure all architecture complies with PCI-DSS standards, GDPR/CCPA, and general security best practices for handling sensitive customer financial data.
  • Drive the migration from monolithic architecture to a Headless/Composable Commerce approach (Microservices/API-first).
  • Manage AWS budgets and implement FinOps best practices to optimize cloud spend.

  • Experience with Microservices and API design (REST/GraphQL).
  • Strong understanding of Containerization (Docker/Kubernetes).
  • Familiarity with Infrastructure as Code (Terraform or CloudFormation).
  • Experience designing schemas for both relational (RDS/Aurora) and NoSQL (DynamoDB) databases in a commerce context.
