Job Description:
We Dream. We Do. We Deliver.
At Merkle, a dentsu company, we power the experience economy. Whether we’re building the next great app, running CRM at scale for global brands, delivering technology architectures that support millions of users, or providing world-class data, identity, and insights solutions, it’s all in the name of crafting experiences that set brands apart from the competition. Backed by dentsu's legacy of innovation and creativity originating in Japan, we’ve spent over 35 years helping brands build loyalty, drive growth, and connect meaningfully with their audiences.
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.
-
Experience: 7+ years in software engineering, with at least 3+ years specifically in Solution Architecture.
-
AWS Expertise: Advanced knowledge of the AWS ecosystem. AWS Certified Solutions Architect (Associate or Professional) preferred.
-
Commerce Domain: Proven experience building or maintaining large-scale e-commerce platforms (e.g., commercetools, Shopify Plus, Adobe Commerce/Magento, Salesforce Commerce Cloud, or custom builds).
Technical Skills:
-
Experience with Microservices and API design (REST/GraphQL).
-
Strong understanding of Containerization (Docker/Kubernetes).
-
Familiarity with Infrastructure as Code (Terraform or CloudFormation).
-
Data & Database: Experience designing schemas for both relational (RDS/Aurora) and NoSQL (DynamoDB) databases in a commerce context.
-
Experience with event-driven architecture (Kafka, EventBridge, SQS/SNS).
-
Background in retail, logistics, or supply chain technology.
-
Experience with frontend frameworks (React/Next.js/Vue) to understand the full stack requirements of a Headless setup.
-
Communication: Ability to explain complex architectural decisions to non-technical stakeholders (Product Managers, Merchants).
-
Leadership: Mentoring senior engineers and conducting code/design reviews.
-
Pragmatism: Ability to balance "perfect architecture" with business deadlines and budget constraints.
