Continuous Improvement Manager

Lead the way in lean – and make impact across borders
Do you thrive on shaping strategy and driving transformation? Are you ready to lead continuous improvement on an international scale?

Within Maltha (part of Renewi) we are looking for a visionary and results-driven Manager Continuous Improvement who can turn strategy into impact—by leading cross-functional improvements, embedding Lean thinking, and building the capabilities that will power our growth. If you’re ready to elevate performance, connect teams across borders, and help us build a future-proof operation, we would love to meet you.

Continuous Improvement Manager (40 hours)
Work location flexible, based in either Lommel (BE) or Heijningen (NL)

As Manager Continuous Improvement, you’ll be the driving force behind operational excellence across multiple sites and countries (future scope includes France). You’ll work on strategic initiatives, lead impactful Kaizen events, and help embed a culture where continuous improvement is the norm, not the exception.
This is your chance to shape and scale CI in a dynamic, purpose-driven company that’s at the heart of the circular economy.

Your Role: Strategy Meets Execution
You will:

• Build and drive our CI improvement program across locations in Belgium, the Netherlands—and in time, France.
• Define, prioritise and monitor the benefits from the agreed improvement projects.
• Perform maturity assessments and shape our Lean transformation approach based on clear priorities.
• Facilitate Kaizen events and lead projects that improve performance, safety, and employee engagement.
• Implement standards across sites (5S, process design, Mission Control, problem-solving methods).
• Create and roll out a training program to upskill colleagues in Lean tools and CI principles.
• Promote cross-site collaboration and alignment between teams, departments, and leadership.
• You’ll report to the International Operations Manager, work closely with the leadership team and manage our CI Specialist(s).

What makes you our ideal Continuous Improvement Manager?

• You combine vision with execution power, and you know how to mobilise teams behind a shared ambition. You’re a structured thinker, a persuasive communicator, and a change agent with business acumen.
• Proven experience leading CI or operational excellence programmes across multiple sites
• A solid foundation in Lean (Green or Black Belt preferred), Kaizen, and CI methodologies
• Experience with CI tools such as A3 management, 5S, process mapping, PDCA, and problem solving
• Strong stakeholder management skills – you bring clarity and connection across functions and levels
• Fluent in English and some Dutch, ideally some French
• Experience in industrial, logistics, or manufacturing environments is a strong plus
  Willing to travel across the Netherlands and Belgium, in time, France.

What do we offer you?

• A competitive salary (max € 8.500 per month) 8% holiday allowance, 15% bonus, company car, a good pension scheme, laptop and phone and a minimum of 27.5 holiday days (and you can buy 20 more if you need);
• A chance to grow while contributing to a cleaner, greener world.
• Work in a highly dynamic, innovative environment with freedom to explore and create.
• The opportunity to build something that lasts—not just projects, but culture.
