## Description

We've been named a global "Leader" by top industry analyst firms in categories as wide-ranging as digital transformation and commerce, experience design, engineering and technology integration, digital marketing, data science, CRM and loyalty, and customer data management.
We are looking for a hands-on Commerce Architect to design and oversee our highly scalable e-commerce infrastructure on AWS. You will bridge the gap between complex business requirements (merchandising, checkout, inventory) and cloud-native technical solutions. You will own the architectural roadmap for our commerce platform, ensuring high availability, security (PCI-DSS), and performance during peak traffic events., + Architectural Strategy: Design and maintain a cloud-native architecture using AWS services (Lambda, API Gateway, DynamoDB, EKS, CloudFront) to support high-volume transaction processing.

 + Commerce Integration: 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).
 + Performance & Scalability: Architect solutions for "bursty" traffic (e.g., product drops, holiday sales), utilizing auto-scaling, caching strategies (Redis/ElastiCache), and CDNs.
 + Security & Compliance: Ensure all architecture complies with PCI-DSS standards, GDPR/CCPA, and general security best practices for handling sensitive customer financial data.
 + Modernization: Drive the migration from monolithic architecture to a Headless/Composable Commerce approach (Microservices/API-first).
 + Cost Optimization: Manage AWS budgets and implement FinOps best practices to optimize cloud spend.
