Senior Node.js Engineer (AWS Serverless)

About the Client & Project We are partnering with a well-established UK-based e-commerce retailer operating across the US, UK, and APAC markets under 16+ partner brands. They run a high-volume, subscription-driven commerce model with complex multi-market business logic. The team is currently mid-way through a major platform modernisation — moving from a legacy monolith to a modern MACH architecture.

Responsibilities:

• Build AWS Lambda microservices (Node.js/TypeScript) behind API Gateway, integrated with Commerce Tools and D365.
• Design and optimise DynamoDB data models and access patterns for high-throughput e-commerce.
• Contribute to CI/CD pipelines and collaborate with DevOps on infrastructure automation.
• Support knowledge transfer to client engineers on AWS serverless best practices.

• Delegate multi-step tasks to AI agents; review diffs, verify output, and maintain accountability for what gets committed.

   

Requirements:

• Experience: 5+ years in Software Development 
• Backend: Strong, production-grade proficiency in Node.js and TypeScript.
• Cloud5/Serverless: Production-grade expertise with AWS Lambda, API Gateway, and DynamoDB (not just theoretical).
• Architecture: Robust experience with microservices architecture and greenfield development.
• AI Tooling: You are a self-sufficient builder who ships fast, communicates clearly across international teams, and operates AI agents as a genuine force multiplier — delegating, verifying, and iterating, not just prompting.
• English level: Upper-Intermediate+
• Tech Stack Ecosystem (Nice-to-Have): Exposure to ECS, Commerce Tools, Netlify, Contentful, D365, or Akamai

We offer*:

• Flexible working format - remote, office-based or flexible
