Sr. Lean/CI Practitioner

Role Summary

Join our team as a

Sr. Lean/CI Practitioner for CNC!

This is an ONSITE role based out of our Brooklyn Park, MN CNC location.

We are seeking an experienced and highly influential Senior Continuous Improvement Practitioner to advance operational excellence at our CNC manufacturing facility in Brooklyn Park.

• Design and strengthen daily management systems, including visual management, accountability routines, and leader standard work.
• Develop organizational capability through coaching, training, and implementation of standardized work and continuous improvement practices.
• Establish performance metrics and management routines that drive accountability, measure results, and support data-driven decision-making.
• Partner with business leaders, frontline teams, and stakeholders to drive change adoption, sustain improvements, and build a culture of continuous improvement.
