It’s fast-paced and hands-on, with teams working together to ensure quality, efficiency and sustainability at every stage.

About the role:
Join our dynamic Quality team at the world-famous St. James’s Gate Brewery in Dublin as a Micro Analyst & Day Support—a role at the heart of ensuring the quality and consistency of some of the world’s most iconic brands.
Reporting to the Quality Manager, you’ll work closely with production, brewing, and quality teams across the site to provide critical microbiological analysis that supports both day-to-day operations and wider site projects. Your work will directly contribute to maintaining the high standards expected across Diageo’s global supply chain.
This is a hands-on, fast-paced role where no two days are the same. You’ll be balancing routine analysis with problem-solving, collaborating with multiple teams, and continuously looking for ways to improve processes and outcomes.

Collaborating across teams:
This role involves regular interaction with cross-functional teams, building strong working relationships and ensuring a seamless flow of information between Quality and Operations.
Supporting and developing others:
You’ll help train and guide laboratory staff and production personnel on QC testing methods, contributing to capability building across the site. While the role has no direct reports, you’ll act as a subject matter support for newer team members.
Providing flexible shift support:
In addition to your core responsibilities, you’ll support shift-based Micro Analysts when required—bringing flexibility and adaptability to meet business needs.
Continuous improvement & problem solving:
You’ll be encouraged to challenge existing processes, identify improvement opportunities, and contribute to enhancing efficiency, quality, and performance across the lab and wider site.
