What these engineers do

Manufacturing and process quality engineers are quality engineers who live on the production floor. Where a general quality engineer may cover design, suppliers and systems, these roles focus on making the process capable and keeping it in control.

Manufacturing quality engineerProcess quality engineer
Main focusProduct quality coming off the lines: defects, scrap, containment, customer complaintsCapability and stability of specific process steps (molding, machining, filling, sterilization)
Typical toolsControl plans, layered process audits, nonconformance and MRBSPC, process capability, design of experiments, process validation
Common industriesAutomotive, aerospace, electronics, devicesChemicals, pharma, semiconductors, devices

In practice many companies use the two titles interchangeably.

Typical responsibilities

  • Owning control plans and process FMEAs for assigned lines
  • Monitoring SPC and responding to out-of-control signals
  • Leading material review board (MRB) decisions on nonconforming product
  • Running process capability and validation studies (IQ/OQ/PQ in regulated industries)
  • Driving scrap, rework and defect reduction projects
  • Supporting production changes through change control

A day in the job

TimeTypical activity
Start of shiftWalk the line; review overnight SPC alarms and holds
MorningMRB meeting to disposition nonconforming material
MiddayDesign-of-experiments trial or capability study with process engineering
AfternoonUpdate PFMEA and control plan after a change; write validation protocol
End of dayReport scrap and defect trends; plan next day’s containment checks

Who you work with

  • Production supervisors and operators: constant contact on the floor.
  • Process and manufacturing engineers: on equipment and parameter changes.
  • Maintenance: when equipment drift causes defects.
  • Quality technicians and inspectors: who collect the data.
  • Plant quality manager: for escalations and customer issues.

Busy periods

Typical patterns rather than measured statistics:

  • Line launches, new equipment and transfers between sites.
  • Customer escalations or field failures requiring containment.
  • Annual or customer-driven audits, for example layered process audits or IATF 16949 surveillance in automotive.
  • Production ramps and quarter-end shipment pushes.

Skills you need

  • SPC, capability analysis and design of experiments
  • PFMEA and control plan development
  • Problem-solving methods (8D, DMAIC)
  • Process validation principles
  • Comfort working in noisy, fast-paced production environments

Salary and job outlook

BLS includes these roles under industrial engineers: median pay $102,440 in May 2025, 12% projected growth from 2025 to 2035 and about 23,100 openings a year. O*NET’s industrial engineer tasks include coordinating quality control objectives to solve production problems, improve reliability or reduce costs.

A Green Belt is often the first certification for process roles because it can be earned earlier; CQE follows once experience requirements are met.

Career path

  1. Quality technician or process technician → Manufacturing / Process Quality Engineer
  2. Senior Quality Engineer or Six Sigma Black Belt
  3. Quality Engineering Manager or Plant Quality Manager
  4. Operations or site leadership

Checklist: what hiring managers look for

  • Concrete scrap or defect reduction results with numbers
  • Owned a PFMEA and control plan
  • Ran a capability study or DOE and acted on the result
  • Experience with MRB and containment
  • CSSGB now; CQE when eligible

How AskDona helps

Process validations, control plans and PFMEAs must stay consistent as processes change. AskDona reads validation protocols and reports, control plans and change records together and flags mismatched parameters, missing acceptance criteria or changes without revalidation, citing the page. Run a sample process validation and control-plan review on one line. AskDona shows the evidence; your engineering and quality teams decide.

Editor’s note: BLS figures are for industrial engineers, the category O*NET maps to quality engineer titles; manufacturing and process quality engineers are not separately reported. Busy periods are typical patterns, not survey data.

FAQ

What does a manufacturing quality engineer do? Keeps production quality under control through control plans, SPC, MRB decisions, containment and defect reduction.

What is a process quality engineer? A quality engineer focused on making specific process steps capable and stable, often through SPC, DOE and process validation.

How much do manufacturing quality engineers earn? BLS reports a $102,440 median for industrial engineers in May 2025.

Is a Green Belt or CQE better? Green Belt can be earned sooner and is lifetime; CQE is broader and more senior.

What is the career path? Senior or lead quality engineer, then quality engineering manager or plant quality manager.
