Company Information:
Holroyd Precision Rotos Inc. is a leading manufacturer of compressor rotor screws based in the Spartanburg area.
We specialize in the manufacture of high-quality, precision engineered helical components for various industries.
We are seeking an experienced Process Engineer to support and optimize a high precision CNC manufacturing operation producing compressor screw rotors to extremely tight tolerances.
This role is ideal for an engineer who thrives in a technically demanding, multi stage machining environment and has a passion for continuous improvement, Lean manufacturing, and mistake proofing processes.
Job Purpose:
As the process development specialist you will play a key role in improving production efficiency, process capability, and right first-time quality.
The first major project will be to design and implement a structured process improvement initiative using a recognized model, focusing on mistake proofing principles, embedding quality and control directly into the manufacturing process rather than relying on downstream inspection.
You will work closely with our local and UK engineering team to implement a controlled process so quality and efficiency is achieved through regulated machine set-ups and operation.
Critical to this role is experience of working within an environment of multi-axis CNC machinery (Milling, Turning and Grinding) in metal cutting producing low volume high quality precision components.
Responsibilities:
Analyze and optimize CNC machining processes for helical screw rotor components across multiple metal cutting operations
Lead process improvement projects focused on yield, cycle time, scrap reduction, and process stability
Design and implement Poka Yoke / mistake proofing solutions to eliminate common sources of error and variation
Develop robust process controls to ensure dimensional accuracy and form integrity at every machining stage
Collaborate closely with Manufacturing, Quality, Engineering, and Maintenance teams to implement sustainable improvements
Review tooling strategies, fixturing, setup methods, and machining parameters to improve consistency and throughput
Support root cause analysis (RCA) and corrective actions for quality or process deviations
Establish standard work, process documentation, and control plans aligned with Lean principles
Drive continuous improvement using methods such as Kaizen, PFMEA, SPC, and capability studies (Cp/Cpk)Implement effective quality systems to support ISO accreditation for the business.
Experience & Qualifications:
Bachelor's degree in Mechanical Engineering, Manufacturing Engineering, or related discipline
Proven experience with CNC machines (Okuma, Doosan, Studer), turning, grinding and milling
Experience using operating software, WinMax or similar, and FANUC or OSP controls
Hands on knowledge of high precision manufacturing and tight tolerance components
Experience machining complex geometries such as helical forms, rotors, gears, or similar profiles strongly preferred
Solid understanding of Lean Manufacturing, Poka Yoke, Kaizen, and continuous improvement methodologies
Familiarity with SPC, PFMEA, process capability analysis, and root cause problem solving
Strong collaboration and communication skills, with the ability to drive change on the production floor
First Project Focus Your initial assignment will be to lead a Poka-Yoke-based improvement program for a complex helical screw rotor undergoing several CNC machining stages.
The objective will be to:
Prevent setup, orientation, and process sequencing errors • Ensure each operation is verified before subsequent machining stages • Detect deviations as early as possible in the process • Build in-process quality that protects final form, profile, and tolerances
Why Join Us • Work on technically challenging, high-precision components used in critical applications • Opportunity to lead meaningful process improvement projects with real production impact • Stable manufacturing environment with a strong focus on quality and engineering excellence • Competitive compensation and benefits package
If you are a Process Engineer who enjoys solving complex manufacturing problems and building quality into every step of the process, we would like to hear from you.
