A quality engineer search has two problems a title cannot solve. "Quality engineer" and "quality assurance engineer" are shared with software testing, so a bare title fills with Selenium and Cypress profiles; and manufacturing quality splits by the industry standard the plant answers to: IATF 16949 and the AIAG core tools in automotive, ISO 13485 and FDA's Quality Management System Regulation in medical devices, and AS9100 in aerospace. As of November 2026, the strongest single block in the string is that standard, written under every name candidates use, plus the tools that prove the work (PPAP, PFMEA, control plans, SPC, MSA, CAPA).
Below are ten strings by industry and kind of quality work, and what LinkedIn, Indeed and Google support as of November 2026. For software testers, see Boolean search strings for QA engineers; for the engineers who design the process the quality engineer controls, see Boolean search strings for manufacturing engineers.
Standards, tools and certifications that change what a quality engineer search finds
| Industry | Standard or rule candidates write | Work words that prove it |
|---|---|---|
| Automotive | IATF 16949, TS 16949 on older profiles | APQP, PPAP, PFMEA, control plan, MSA, gage R&R, SPC, 8D |
| Medical devices | ISO 13485, 21 CFR 820, QSR, QMSR | CAPA, design controls, complaint handling, IQ/OQ/PQ, risk management |
| Aerospace and defense | AS9100 | First article inspection, nonconforming material, MRB, special processes |
| General manufacturing | ISO 9001 | Internal audits, root cause, corrective action, Six Sigma |
- Automotive. AIAG's Quality Core Tools page lists the manuals for APQP, Control Plan, PPAP, FMEA (including the harmonized AIAG & VDA FMEA), SPC and MSA, as of November 2026. IATF 16949:2016 is the edition in force; the IATF's July 2026 Stakeholder Communiqué plans the second edition's publication for mid-2027 and calls the dates indicative.
- Medical devices. FDA's QMSR page says the rule took effect on February 2, 2026, amends the device good manufacturing practice requirements of 21 CFR Part 820 and incorporates ISO 13485:2016 by reference. Long careers will say QSR or "21 CFR 820," newer profiles QMSR, so search all of them.
- Aerospace. The IAQG's standards page lists 9100, quality management system requirements for aviation, space and defense organizations; candidates usually write AS9100.
- ASQ certifications. ASQ's Certified Quality Engineer (CQE) page requires eight years of on-the-job experience in the CQE body of knowledge, three of them in a decision-making position, with a bachelor's degree waiving four years, as of November 2026. The Certified Supplier Quality Professional (CSQP) and Certified Reliability Engineer (CRE) pages set the same eight-and-three requirement, and the Six Sigma Black Belt (CSSBB) page asks for three years plus one or two completed projects with signed affidavits.
- Verification. ASQ's Certification Verification Registry is there for employers and recruiters to verify a certification, but ASQ says inclusion is voluntary and holders can opt out, so a missing name is not proof of a false claim.
Ten Boolean strings by industry and kind of quality work
Swap in the industry, standard and metro from your own intake; these are examples. Search on the work and the credentials, never on a term that stands in for age, sex, race, religion, national origin, disability or veteran status.

site:linkedin.com/in "quality engineer" "ppap" "iatf 16949" "grand rapids" -jobs -recruiter -seleniumWhat LinkedIn, Indeed and Google actually support
LinkedIn's Boolean help page requires capital AND, OR and NOT, supports quotes and parentheses, evaluates quotes first, then parentheses, NOT, AND and OR, and does not support wildcards, as of November 2026. That is why "as9100" and "as 9100," and "iso 13485" and "21 cfr 820," go in as pairs. The page does not say how symbols such as & and / are matched, so test "gage r&r" and "iq/oq/pq," and add the spellings "gauge r&r" and "gage rr." LinkedIn Recruiter's Boolean page lists Job titles among its Boolean filters and warns that too many facets in one query can cause a search result issue, so keep the title variants in Job titles and the standard in Keywords.
Indeed's repair
and maintenance guide documents the skill: field and fieldofstudy:, with an
example that pairs an engineering title with fieldofstudy: "mechanical engineering"; add
fieldofstudy: ("industrial engineering" OR "mechanical engineering") when the client insists on
an engineering degree. Google's search
operators page documents quotes, site:, the minus sign, filetype: and the
before: and after: date operators, but not OR, so string 10 uses none.
Narrowing by plant, supplier or design side
Ask where the quality engineer sits. A plant quality engineer lives on the line: control plans, SPC charts, containment and customer complaints. A supplier quality engineer travels to suppliers, approves PPAPs and drives supplier corrective actions. A design quality engineer in medical devices works with R&D on design controls, risk files and verification. Each writes different words, and the industry standard alone will not separate them.
Seniority shows in ownership: "owned PPAP submissions," "led customer audits," "chaired the MRB," "closed CAPAs" and "hosted the FDA inspection," against "supported" and "assisted." LinkedIn's premium search filters page says Years of Experience and Seniority Level are only in Recruiter and Sales Navigator. When the role leans toward running the whole quality system, the 30-60-90 day plan for quality managers shows what that seat owns.
False positives worth excluding with NOT
- Software QA engineers. Selenium, Cypress, Playwright, ISTQB and "test automation" profiles share the title. Exclude those terms and require a manufacturing standard.
- Quality inspectors and technicians. They write CMM, first article and ISO 9001 at the inspection level. Exclude inspector for engineer roles, and see the quality inspector screening questions when the client needs one.
- Site reliability engineers. "Reliability engineer" also means cloud operations. Exclude "site reliability," sre and kubernetes from product reliability searches; for that role, see Boolean search strings for site reliability engineers.
- Call center and data quality roles. "Quality analyst," "call quality" and "data quality engineer" come from contact centers and data teams. Exclude them by phrase.
- Food and pharmaceutical QA, when the role is devices or automotive. HACCP, SQF, batch record review and GMP release are a different quality world. Keep them out unless the client is in that industry.
- Buyers and auditors for hire. Purchasing staff mention supplier quality, and registrar auditors mention every standard. Exclude buyer, procurement and "certification body" for in-house roles.
A worked example: three passes on a medical device quality engineer search
An invented search, shown as it actually gets narrowed.
Intake: A contract manufacturer of single-use surgical devices needs a quality engineer to own CAPAs and complaint investigations and support process validation on new molding lines. Not looking for software testers or pharmaceutical QA specialists.
Pass 1: "quality engineer" AND "medical device": a large mix including
software QA engineers at medical software companies and regulatory affairs staff.
Pass 2: ("quality engineer" OR "quality systems engineer") AND ("iso 13485" OR
qmsr OR "21 cfr 820") AND (capa OR "complaint handling") NOT (selenium OR "software testing"):
device quality engineers, though many sit in design quality at product companies.
Pass 3: add AND ("process validation" OR "iq/oq/pq" OR molding). Those words
tend to come from engineers who work on a production floor. The list is short enough to call, and the screen
asks them to walk through their last CAPA from the trigger to the effectiveness check.
The regulation block found device quality engineers; the process block found the ones who work where the product is made. The QMSR name will appear on more profiles each year, so keep it beside the older names.
What a search cannot verify
A string can find someone who names the right standard, tools and certification. It cannot show whether they found the root cause or wrote a report around it, whether a PPAP they "owned" was approved first time, or whether a certification is current. Check ASQ certifications in the registry, then use the interview questions for quality focus to test how they hold the bar, and the interview guide for manufacturing roles for the plant loop. When the candidate came from the inspection bench, the quality inspector job description template shows where that role ends and the engineer's begins.
Questions people ask
How do I stop a quality engineer search from returning software testers?
Require a manufacturing standard or tool, such as IATF 16949, ISO 13485, AS9100, PPAP, PFMEA or SPC, and exclude software terms such as Selenium, Cypress, "test automation" and "software testing" with NOT. "Quality assurance engineer" is the title both groups share, so never search it on its own.
What should a Boolean string for a medical device quality engineer include?
Include the regulation and the standard under several names: "iso 13485," "21 cfr 820," "part 820" and QMSR. FDA's Quality Management System Regulation took effect on February 2, 2026 and incorporates ISO 13485:2016 by reference, so newer profiles may write QMSR while longer careers say QSR. Add CAPA, design controls or complaint handling for the kind of work.
How do I verify an ASQ Certified Quality Engineer?
Search ASQ's Certification Verification Registry, which ASQ says lets employers and recruiters verify an individual's certification. Listing is voluntary, so a holder who opted out will not appear; in that case ask the candidate for their certificate and confirm it with ASQ.
Is a supplier quality engineer search different from a plant quality engineer search?
Yes. Supplier quality engineers write about supplier audits, PPAP approvals, supplier corrective actions and incoming inspection, and they travel to suppliers; plant quality engineers write about the line, control plans, SPC and customer complaints. Lead with the block for the side the client needs.
