RabbitMQ Expert – Industrial Systems (Windows / .NET)

Location: Remote with occasional on‐site office based day in Hoyland, Barnsley Contract: Short‐term consultancy or project-based engagement Start: Immediate

We are looking for an experienced RabbitMQ specialist to support a distributed factory‐floor data system built on Windows PCs with local RabbitMQ instances.

About the Environment

Our setup consists of multiple Windows‐based machines operating in a low‐connectivity factory environment (little to no internet access). Each machine hosts its own RabbitMQ instance and performs a specific role:

Node PCs:

Monitor individual pieces of factory equipment

Store equipment data locally in RabbitMQ

Write only to their own instance, but read from others over the local network

Central Controller:

Reads data from all node RabbitMQ instances

Performs processing and aggregation

Writes processed data into its own RabbitMQ instance for downstream steps

Data flows bi‐directionally between nodes and the controller. All applications are built in .NET (C# and VB) and run on Windows with the latest RabbitMQ versions installed. xcunqrw
