About The Position

Donaldson is hiring a Manufacturing Engineer in Stilwell, Oklahoma. This role connects product design with the production floor and owns the processes, tooling, and documentation needed to produce repeatable, cost-effective output. The position spans prototype builds, manufacturing process development for new products, improvements to existing processes, cost reduction, and implementation of engineering changes. The role requires working on site at the Stilwell facility and involves 25% travel.

Requirements

• B.S. in Engineering (Mechanical, Manufacturing, Industrial, or a closely related discipline), or equivalent experience.
• At least 3 years of manufacturing engineering experience in a low-to-medium-volume, high-mix engineered-products environment.
• Demonstrated ability to develop and document manufacturing processes for new or transferred products, with practical understanding of process capability, measurement system analysis, and sampling plans.
• Demonstrated working knowledge of APQP methodology and its core work products, including DFMEA, PFMEA, Control Plans, and Work Instructions.
• Working knowledge of GD&T, engineering drawings, and dimensional inspection methods.
• Proficiency with ERP/MRP systems, including bills of material, routings, and standards, and CAD such as SolidWorks or equivalent.
• Must be legally authorized to work in the United States without current or future sponsorship.
• Must be able to work on site at the Stilwell, Oklahoma facility.

Nice To Haves

• Lean, Six Sigma (Green Belt or higher), or equivalent structured continuous improvement training.
• Formal APQP/PPAP training or experience in an AIAG-aligned or IATF 16949 environment.
• Experience in filtration, fluid handling, energy, or process equipment markets.
• Exposure to ISO 9001 quality systems and code-driven or customer-specified product requirements.
• Hands-on capability with fixture design and shop equipment.

Responsibilities

• Plan, fixture, build, and document prototype units for new product development, including first-article inspection and build reports that capture lessons learned.
• Improve manufacturing processes by identifying and eliminating bottlenecks, scrap, rework, and non-value-added labor using lean and structured problem-solving methods; quantify baseline and post-implementation results.
• Develop manufacturing processes for new products, defining process flow, work instructions, tooling and fixture requirements, equipment selection, cycle times, labor standards, and quality checkpoints.
• Participate in design reviews to promote design for manufacturability.
• Implement and sustain APQP discipline for new and existing products; lead stage-gate quality planning deliverables and ensure they are completed as launch prerequisites.
• Contribute to DFMEAs with Design Engineering and author and maintain PFMEAs for assigned processes.
• Translate high-RPN failure modes into Control Plans specifying characteristics, requirements, measurement methods, sampling and reaction plans, and cascade controls into clear, visual, operator-level Work Instructions.
• Complete process capability and measurement system studies, including Cp/Cpk and Gage R&R, and manage PPAP or equivalent submission packages when required by customers.
• Maintain FMEAs and Control Plans as living documents, updating them after engineering or process changes, customer complaints, and corrective actions, and audit floor adherence.
• Manage engineering change requests by evaluating technical and cost impacts, coordinating review and approval, managing effectivity and inventory disposition, and ensuring routings, bills of material, and work instructions are updated accurately and on time.
• Lead cost-reduction initiatives by maintaining a funnel of material, labor, process, and design-based projects with quantified savings, owners, and target dates, and report progress against an annual savings goal.
• Support production troubleshooting and root cause analysis for process-driven quality escapes, including corrective and preventive action ownership.
• Support supplier and outsourced process qualification in partnership with Supply Chain and Quality.
• Maintain accurate manufacturing documentation and master data, including routings, standard times, work instructions, and process control plans.
