Integration Engineer

Numi is partnering with a leading global food and beverage retailer undergoing a major digital transformation to recruit for the following position:

The Integration Engineer will be hands‑on in the day‑to‑day build and operation of the company’s modern integration estate.

All new integration assets are being built on Azure. There is also a legacy Mulesoft Anypoint estate which the team is actively migrating away from; you will contribute directly to migrating these individual flows onto the modern Azure stack.

Working as part of a collaborative, fast‑paced team, you will write clean, well‑tested Azure code, actively participate in peer reviews, and grow rapidly under strong technical leadership.
