Our Supply Chain and Manufacturing team are problem-solvers, sourcing, producing, and delivering our much-loved brands to delight customers around the globe. Over half of Diageo’s 30,000+ people work in Supply Chain and Manufacturing. It’s an intricate and sophisticated operation that’s the product of logistical, manufacturing, and technical collaborations.
Our teams in 100 sites in over 30 countries cover production facilities, supplier relationships, customer collaborations and third-party agreements. We’re committed to realising our ‘Society 2030: Spirit of Progress’ goals, to protect the environment and support our farmers and suppliers. Whatever your skills and experience, we’ll help you to thrive in our inclusive culture.
As a Reliability & Controls Engineer you’ll be the site subject matter expert for PLC and control systems playing a critical role in maintaining and improving the technology that underpins manufacturing performance.
You’ll be responsible for ensuring all control systems are reliable, supportable and future-proofed. This includes providing rapid breakdown support, owning PLC standards and backups and managing OT assets to minimise risk and downtime.
You’ll also drive continuous improvement across the site, using your expertise to optimise performance, enhance system capability and ensure robust control system design and compliance with safety standards.
The ideal candidate will be a time-served Controls or Electrical Engineer with strong hands-on experience in Siemens PLC systems (S7/TIA Portal) and a proven ability to fault-find in high-pressure breakdown situations.
You’re confident working across HMIs, drives and industrial networks and can interpret electrical schematics and control logic with ease.
With a proactive, problem-solving mindset, you’re comfortable coaching and upskilling others while influencing best practice across the site.
You bring strong communication skills, a focus on continuous improvement and an understanding of system ownership, asset management and risk mitigation.
Experience with PLC backups, OT environments or high-volume manufacturing would be advantageous, but most importantly you bring energy, ownership and a drive to improve performance every day.
