We are looking for a Machining Process Engineer passionate about cutting metallurgy, advanced metrology, and high-speed production line optimization. In this role, you will be the end-to-end technical owner of the machining process for major structural components (CGI/cast iron engine blocks, aluminum cylinder heads, or forged steel crankshafts), driving dimensional stability, the introduction of new tooling, cost-per-part (CPP) reduction, and the alignment between product blueprints and the statistical capabilities ($C_p, C_{pk}$) of our CNC machining centers.
Process Ownership and Dimensional Capability: Design, validate, and optimize machining processes (milling, deep-hole drilling, reaming, boring, and honing) to ensure critical engine features achieve micron-level tolerances and statistical capabilities (Cp,Cpk≥1.67Cp, Cpk \ge 1.67Cp,Cpk≥1.67).
Tooling Management and Cost Reduction (Tooling & CPP)
Lead the selection, trial, and optimization of cutting tools (cemented carbide, PCD inserts for aluminum, and CBN for iron/CGI) in partnership with world-class tooling vendors (Sandvik, Kennametal, Mapal, Guhring).
Develop tool life strategies, flank wear criteria, and regrind/reconditioning programs to systematically drive down Cost Per Part (CPP) without compromising quality.
Metrology Correlation and CMM
Interpret daily dimensional reports from Coordinate Measuring Machines (CMM), surface profilometers (Ra,Rz,RkRa, Rz, RkRa,Rz,Rk) and air gauges.

Translate geometric deviations into immediate work offset updates (G54−G59G54-G59G54−G59), tool wear compensations, or mechanical adjustments to workholding fixtures.
Cycle Time Optimization and Throughput
Analyze cutting kinematics and non-cutting movements (air cuts) within numerical controllers (Siemens 840D / Fanuc), optimizing tool paths to eliminate bottlenecks and sustain target production line cadence (JPH).
Technical Documentation and Core Tools (APQP / FPS)
Author and audit live process documentation: Machining PFMEAs (failure modes: journal/bore misalignment, exposed porosity, stripped threads, harmonic chatter), Control Plans, Tool Layout Sheets, and Operator Instruction Sheets (OIS / JES).
Engineering Change Management: Plan and coordinate Plant Trial Runs (PTR) for new part number introductions, product engineering changes (WERS), or modifications in raw casting/forging stock.
Cutting Fluids and Industrial Washing Support: Monitor and optimize concentration, pH, and filtration of water-soluble coolant or Minimum Quantity Lubrication (MQL) systems, as well as parameters for industrial part washers and thermal/high-pressure waterjet deburring cells.
Bachelor’s Degree with a Professional License (Cédula Profesional) in Mechanical, Mechatronics, Metallurgical, Manufacturing, Industrial Engineering, or a related field.
3 to 5+ years of proven experience as a Process, Manufacturing, or Tooling Engineer on high-volume CNC machining lines in the automotive industry (hands-on experience in machining engine, transmission, chassis, or brake components is essential).
Advanced / Fluent English (B2+ to C1). Essential for daily communication with Product Engineering (Powertrain D&R in Dearborn) and US-based machine and tooling builders.
