Job Description

Lean Manufacturing Process Optimization Engineer

Precinmac is a leading diversified manufacturer of high‑tolerance precision machined components and assemblies across ten independently owned companies in the U.S. and Canada. We win through continuous improvement, reliable delivery, and unwavering quality.

Location: Tualatin, Oregon (on site at Shields Manufacturing — not a remote role)

Schedule: Monday–Friday, 8:00 a.m.–4:30 p.m.

Salary range: $85K–$95K annually

Benefits: Medical, Dental, and Vision (3 plan options); Company-paid Life & Disability; 401(k) with up to 5% company match; generous PTO; and a discretionary quarterly bonus up to 5%.

Make an Impact. Improve Processes. Drive Results.

A day in the life: You start at the tiered visual performance boards, turning yesterday’s data—efficiency, scrap, rework, downtime, and delivery—into today’s actions. By mid-morning, you’re on the floor with machinists at multi-axis mills and lathes, running a SMED trial on a high-mix changeover. After lunch, you map a value stream, capture standardized work, and post a new countermeasure to our Precinmac Way huddle board. You finish the day coaching a Kaizen team, confirming results, and queuing sustainment checks.

What you will lead

• End-to-end continuous improvement initiatives that lift productivity, quality, cost, safety, and delivery.
• Cross-functional prioritization with machinists, supervisors, engineers, and leadership to focus on high-impact opportunities.
• Data-driven analysis of efficiency, scrap, rework, downtime, and delivery performance to identify constraints and waste.
• Year-over-year Variable Cost Productivity (VCP) gains through structured projects and verified savings.
• Kaizen events from chartering to implementation, follow-up, and sustainment.
• Lean tools in action: 5S, SMED, Value Stream Mapping, Standard Work, Visual Management, Mistake-Proofing, and TPM.
• Idea flow via our Precinmac Way huddle boards and TPW system—moving ideas from insight to implementation.
• Standardized work and process documentation to drive repeatability and training.
• Daily management with tiered visual performance boards to surface issues and trigger rapid countermeasures.
• Training and coaching teams in Lean and CI problem-solving methods.
• Project governance: timelines, objectives, documentation, savings calculations, approvals, and sustainment tracking.
• Hands-on partnership with manufacturing so improvements are practical and stick.
• Cultural stewardship—helping make continuous improvement how we work every day.

What you bring Required

• 3+ years in Continuous Improvement, Lean Manufacturing, Manufacturing Engineering, or Process Improvement within manufacturing.
• Hands-on exposure to manufacturing processes; CNC machining (multi-axis milling and turning) strongly preferred.
• Solid command of Lean and CI methodologies and experience leading projects or Kaizen events.
• Analytical problem-solver who converts data into action and measurable results.
• Strong project management, organization, and follow-through.
• Clear communicator who collaborates effectively across all levels.
• Proficiency with Microsoft Office, especially Excel; experience with ERP and/or MES.

Preferred

• Bachelor’s degree in Engineering, Engineering Technology, Business, Manufacturing, or related field—or equivalent experience.
• Lean Six Sigma Green Belt (reputable provider).
• Experience with Infor10 ERP (Syteline) and ShopVue.
• Kaizen facilitation and internal Lean/CI capability building.
• Deep familiarity with CNC machining workflows.

Success profile

• Bias for action; you go solve it.
• Comfort on the shop floor working shoulder-to-shoulder with production teams.
• Root-cause thinker with practical countermeasures.
• Measures what matters and tracks sustainment.
• Influences without relying on authority alone.
• Juggles multiple priorities while keeping stakeholders aligned.
• Persists through implementation to locked-in results.
• Believes there’s always a better way.
