Azure Integration Engineer

Senior Azure Integration Engineer – Azure & TypeScriptRole Overview

We are looking for a Senior Azure Integration Engineer with strong expertise in Azure-native integration, TypeScript/Node.js, containerized applications, and enterprise integration migrations.

The ideal candidate will independently design, develop, optimize, and support production-grade integration solutions on Azure. The candidate must be capable of reverse-engineering existing integrations, including MuleSoft and other ESB platforms, and translating them into scalable, secure, Azure-native architectures.

This is a hands-on engineering role requiring strong technical ownership, architectural thinking, and the ability to deliver integrations end-to-end with minimal supervision.

Ideal Candidate Profile

The ideal candidate is a hands-on senior integration engineer who combines:

Enterprise Integration + Azure + TypeScript/Node.js + Event-Driven Architecture + Containerization + DevOps + Migration/Modernization

They should be able to take an existing enterprise integration, understand how it works, determine the appropriate Azure-native architecture, implement it in TypeScript, deploy it using modern DevOps practices, and operate it reliably in production.
