Position Summary:

As a Continuous Improvement Engineer, you will be responsible for recommending and implementing projects that enhance efficiency, accuracy, quality, and overall safety. Your responsibilities will include gathering and analyzing data, creating ROI projections, building fixtures, adjusting Production lines, creating work instructions, and developing detailed project timelines. You will collaborate with all departments and gather feedback from managers and engineers throughout the company.

Qualifications & Requirements

• Green Belt certified in Lean Six Sigma highly preferred
• 3 years+ of continuous improvement experience
• Must have In-depth knowledge on implementation
• Must be able to communicate effectively
• Bachelor’s degree in Engineering required
• Project Management experience required, able to multitask and meet deadlines

Our core values - Accountability, Collaboration, and Empowerment (ACE) - are the foundation of how we operate and drive success. You will take ownership of your contributions, collaborate with a team that gets stuff done, and be empowered to innovate and pursue bold initiatives that drive our business forward.

Are You Our Next ACE?

• Accountable for driving project success by ensuring timelines and budgets are met while rigorously analyzing metrics to validate that improvements are sustainable and effective. Beyond initial implementation, the position involves conducting post-project effectiveness checks to maintain high-quality standards and coordinating stakeholder meetings to ensure organizational alignment. A core component of the strategy includes leading Kaizen events and rapid improvement workshops to solve immediate operational bottlenecks. Furthermore, the role is responsible for mentoring and training staff in Lean methodologies, 5S, and Six Sigma tools, actively cultivating a robust "continuous improvement culture" across the entire team.
• Collaborate by bridging the gap between engineering and manufacturing through cross-functional collaboration and technical guidance, ensuring all stakeholders remain aligned on project milestones and deliverables. As a cornerstone of Continuous Improvement (CI) Engineering, the position moves beyond general data analysis by actively identifying waste and mapping future-state processes to optimize operations. Responsibility extends to the long‑term sustainability of these improvements, involving the regular auditing of standards rather than simply creating work instructions. To ensure measurable success, the role is tasked with defining and tracking critical operational KPIs—such as Overall Equipment Effectiveness (OEE), Cycle Time, and Scrap Rates—to drive data‑driven decision‑making and operational excellence.
• Empowered to lead problem‑solving efforts by guiding the team in analyzing root causes and developing solutions. Identify and address risks associated with operational inefficiencies or process changes, using data and insight to mitigate these risks and drive continuous improvement. Provide expert advice on tooling and fixture design to support manufacturing operations.
