We are looking for a CI Manager to play a pivotal role in delivering new production assets while leading the site's continuous improvement agenda across a fast-paced pet food manufacturing environment.

You will lead commissioning, validation and start-up of new equipment while driving operational excellence through the identification and elimination of production losses. Working in partnership with production, engineering, maintenance and site leadership teams, you will influence stakeholders at all levels to build capability, align priorities and embed a culture of continuous improvement that delivers sustainable business performance.

This role is critical to ensuring our lines start strong, run efficiently and continuously improve—helping us deliver the quality pet nutrition that millions of pets rely on every day.

Key Responsibilities

  • Lead commissioning, validation and start-up (CVS) of new production lines, equipment and new product introductions, ensuring successful operational handover and sustainable performance.

  • Own the site's continuous improvement roadmap, aligning improvement priorities with operational and business objectives.

  • Build strong relationships with production, engineering, maintenance, quality, supply chain and site leadership teams to drive alignment and successful delivery of improvement initiatives.

  • Lead site-wide loss analysis across OEE, waste, downtime and speed loss, translating operational data into business-focused improvement opportunities.

  • Engage and influence stakeholders across all functions to prioritise resources, remove barriers and deliver measurable operational improvements.

  • Lead cross-functional improvement teams, fostering collaboration, accountability and ownership to achieve shared performance goals.

  • Develop and present business cases for improvement initiatives, communicating risks, opportunities and expected benefits to site leadership.

  • Coach and support leaders, engineers and operators in Lean, TPM and structured problem-solving methodologies, building continuous improvement capability across the site.

  • Champion a culture of operational excellence, encouraging data-driven decision making, ownership and continuous learning.

  • Apply structured problem-solving techniques including Root Cause Analysis, 5 Whys and DMAIC to eliminate recurring losses and improve process capability.

  • Monitor, communicate and review improvement performance with key stakeholders, ensuring benefits are sustained and opportunities for further optimisation are identified.

About You

  • Engineering or technical degree (or equivalent experience) within manufacturing or engineering.

  • Significant experience within FMCG or other high-volume manufacturing environments, ideally food or pet food.

  • Proven success leading cross-functional continuous improvement and operational excellence programmes.

  • Strong stakeholder management and influencing skills, with the ability to build credibility and drive alignment across production, engineering, maintenance, quality and senior leadership teams.

  • Demonstrated ability to engage and coach teams at all levels, creating ownership and accountability for continuous improvement.

  • Strong understanding of OEE, loss analysis, reliability improvement and waste elimination.

  • Experience applying TPM, Lean Manufacturing, Six Sigma or equivalent operational excellence methodologies.

  • Excellent analytical, communication and facilitation skills, with the ability to translate operational data into compelling improvement plans.

  • Confident leading change in a fast-paced manufacturing environment while balancing operational priorities and stakeholder expectations.
