The Opportunity

We are looking for an Operational Excellence Specialist to support a manufacturing plant in Leiden on a 12-month contract.

This is a specialist Lean Six Sigma and Continuous Improvement position. You will work closely with teams and specialists to coach them in the practical implementation of Lean tools and methodologies within their day-to-day processes.

The role is focused on Operational Excellence rather than operational production, with a strong emphasis on coaching, continuous improvement and embedding Lean Six Sigma into the organisation.

Key Responsibilities

• Coach specialists and teams in Lean Six Sigma methodologies, including Yellow and Green Belt concepts.
• Lead Kaizen and continuous improvement initiatives.
• Support teams with diagnosis and analysis of operational processes.
• Develop implementation plans for Lean tools and methodologies.
• Help teams apply Lean Six Sigma tools directly within their current processes.
• Work with operational and improvement systems to support analysis and improvement.
• Coach and support stakeholders in effectively implementing Lean practices.
• Drive a culture of continuous improvement across the manufacturing environment.

Your Experience

• Approximately 3 years of specific Lean experience.
• Strong practical experience with Lean Six Sigma.
• Black Belt certification is preferred, although strong practical Lean Six Sigma experience can compensate.
• Manufacturing experience is essential.
• Pharma experience is preferred.
• Experience within a highly regulated environment is highly relevant; experience from other regulated industries will also be considered.
• Strong hands-on experience applying Lean Six Sigma tools in real processes.
• Proven ability to coach and support teams in implementing Lean methodologies.
• English-speaking.

The Ideal Candidate

You are someone who understands that Lean Six Sigma is not simply about knowing the tools — you know how to implement them practically and coach others to use them effectively.

You enjoy working with teams, analysing processes, identifying opportunities for improvement and helping people turn Lean concepts into sustainable improvements.
