Experience
Manufacturing Engineer, Halverton Plastics Group · November 2023 – present
Owns process engineering for a nine-press molding cell and two downstream assembly lines.
- Raised cell OEE from 61% to 84% in eleven months by rebalancing cycle times and moving mold changes off the critical path, recovering about .1M of annual capacity.
- Cut average mold changeover from 74 minutes to 26 through SMED, freeing 310 press hours a year.
- Drove scrap on a glass-filled nylon housing from 6.8% to 1.9% by correcting gate location and a 40°F melt-temperature drift.
- Qualified two backup resin suppliers through full IQ/OQ/PQ, closing a single-source exposure raised in the 2024 customer audit.
Process Engineer, Cranmore Industrial · September 2021 – October 2023
- Launched three molded parts through PPAP with no customer rejections, holding every critical characteristic above 1.67 Cpk.
- Redesigned a manual assembly station around a poka-yoke fixture, taking misbuilds from 1,100 ppm to 90 ppm.
- Reduced press hydraulic downtime 41% by converting reactive repairs to a condition-based PM schedule.
Associate Manufacturing Engineer, Stonefield Tooling · June 2020 – August 2021
- Programmed and proved out 38 CNC fixtures in Mastercam, cutting average setup time by 19 minutes per job.
- Built the first cutting-parameter database the tool room had, from 200 logged runs, extending insert life 27%.

Why this Manufacturing Engineer résumé works
- The lead number is OEE on a named asset, a nine-press molding cell raised from 61% to 84% in eleven months, converted into about .1M a year of capacity a plant manager can budget against.
- Each process fix gives its root cause: scrap from 6.8% to 1.9% by correcting gate location and a 40°F melt-temperature drift shows engineering diagnosis rather than a lucky trend.
- Quality-system language is used in context: PPAP launches holding every characteristic above 1.67 Cpk and IQ/OQ/PQ resin qualification match the terms medical and automotive job ads ask for.
- The Six Sigma Green Belt and CMfgE certificates back up the SMED and SPC work in the bullets, so the credentials read as earned on the floor.
Manufacturing Engineer résumé: common questions
What should a manufacturing engineer resume include?
The lines and processes you own, then results in plant metrics: OEE, scrap rate, changeover time, downtime and ppm defects, each with a before and after. Add quality systems (PPAP, PFMEA, ISO 13485) and the CAD and SPC tools you use.
Do certifications matter on a manufacturing engineer resume?
A Six Sigma Green Belt or Black Belt and SME’s CMfgE are commonly listed in US postings. Put them in a certifications section with the issuer and year, and show a project that used the method in a bullet.
