Quality (QA/QC) jobs in manufacturing and construction
What QC and QA engineers actually do in plants and on sites, the standards and tools employers name, how NDT levels work, and how quality people move up.

Picture a B.E. Mechanical graduate who joins a tier-2 auto-component supplier in Aurangabad's Waluj industrial area as a "QC Inspector – Machining". For the first three months the job is a height gauge, a bore gauge, a stack of inspection reports and a red tag for anything out of tolerance, and it is easy to wonder whether the degree was wasted.
Two years on, an inspector who learns from those months can be the plant's supplier quality engineer, travelling to vendors, running PPAP submissions for a new car model, and getting calls from a larger OEM. The red-tag months are what make that possible: you learn exactly how parts fail.
Quality is one of the few engineering functions that every manufacturer and every large construction project must staff, by contract and often by law. It is also widely misunderstood by freshers, who see "QC" as a dead end. This piece explains what the work is in plants and on sites, what employers ask for, and how the ladder works.
QC and QA are different jobs
People use the terms loosely, but on an organisation chart they're different.
- Quality control (QC) checks the product: incoming material, in-process parts, final inspection, tests. It is hands-on and reactive. You find the problem.
- Quality assurance (QA) builds the system that stops problems: procedures, audits, process approvals, training, corrective actions, customer complaints. You make sure the problem doesn't come back.
Most people start in QC and move into QA. The move usually happens once you've handled a few customer complaints end to end, from containment to root cause to the fix.
Where quality engineers work
On Highlisted in mid-November 2026 there were 1,392 open quality (QA/QC) jobs at 549 employers. The employer list shows the three worlds of quality work clearly:
| World | Who hires | What you do | Examples from the data |
|---|---|---|---|
| Manufacturing | Auto, engineering, electrical, pharma and FMCG plants | Inspection, process quality, supplier quality, customer quality, audits | Maruti Suzuki, Schneider Electric, Siemens, RPG Group companies |
| Construction and projects | EPC contractors, consultants and owners | Material testing, inspection and test plans, welding and NDT checks, non-conformance reports | Larsen & Toubro, Adani Group |
| Testing, inspection and certification | Third-party inspection agencies and labs | Vendor inspections, product testing, certification audits | QIMA, Eurofins |
Third-party inspection and testing agencies such as QIMA and Eurofins were among the busier quality employers in our data. They're a good first employer if you want variety and travel: you inspect at many factories instead of one.
Standards and tools employers actually name
Employers write the same few things into quality job posts again and again. ISO management systems appear in 18.3% of quality posts on Highlisted, quality core tools in 17.4%, GMP in 11.4%, Six Sigma in 9.3% and supplier audits in 8.8%.
In manufacturing
- ISO 9001, the base quality management standard, and IATF 16949 for automotive suppliers, which adds customer-specific requirements on top of it.
- The core tools: APQP (planning a new part), PPAP (getting it approved by the customer), FMEA (what can fail and how badly), MSA (is your gauge reliable) and SPC (is your process stable). If you can explain each with an example from a real part, you'll stand out in an interview.
- Measurement: vernier, micrometer, height gauge, bore gauge, profile projector, and at bigger plants CMM. GD&T on drawings is the language of all of it.
- Problem solving: 8D reports, why-why analysis, fishbone diagrams.
In construction
Site QC is a natural branch for civil engineers who start in execution; our civil fresher jobs piece explains that first step.
- Inspection and test plans (ITPs) that list every check, who does it and when the client must witness it.
- Material tests: concrete cubes and slump, soil compaction, steel and aggregate tests, often at NABL-accredited labs.
- Welding quality: welding procedure specifications and welder qualification records, and visual inspection.
- Non-conformance reports (NCRs) and their closure, which is where site QC people earn their reputation.
In pharma and food
GMP, documentation discipline and deviation handling. Quality roles here have their own path through QA and QC labs, closer to chemistry than engineering.
NDT levels, explained simply
Non-destructive testing (ultrasonic, radiography, magnetic particle, dye penetrant, visual) is how welds, castings and pressure parts are checked without cutting them. It's a separate, certified skill that pays well on oil, gas, power and heavy fabrication projects.
NDT personnel are certified by method and by level:
- Level 1 can carry out tests under instruction and record results.
- Level 2 can set up equipment, perform and interpret tests against the code, and write reports. This is the level most employers ask for.
- Level 3 can write procedures, approve techniques and train and examine others.
In India, the Indian Society for Non-Destructive Testing (ISNT) certifies people under IS 13805 and ISO 9712; its ISO 9712 certificates are recognised in other countries under the ICNDT agreement. Many employers abroad and in oil and gas also follow employer-based certification under the American ASNT scheme. Before paying for any NDT course, ask which scheme the certificate falls under and whether it includes the practical hours that certification needs.
Pay and how quality people move up
Few quality posts state pay. On Highlisted in mid-November 2026, the 61 that did had a median of about ₹4.0 lakh a year across all levels, too few to split by experience. Freshers made up 7.4% of quality posts that state experience (of 948), so most entries are through inspector roles, GET programmes or diploma routes.
A common ladder in manufacturing:
- QC Inspector or Quality Executive
- Quality Engineer
- Senior Quality Engineer, or Supplier Quality Engineer
- Assistant Manager – Quality
- Deputy Manager, then Quality Manager or plant quality head
The jumps that pay most are into supplier quality (you manage vendors, travel a lot, and become hard to replace), customer quality (you face the OEM), and lead auditor roles. An ISO lead auditor course is usually five days; check that it is certified by a recognised body such as CQI and IRCA, and that it covers the standard your industry uses.
On construction projects, QC engineers move from site QC to QA/QC manager for a package or project, some cross over into safety (see safety officer jobs), and many go to the Gulf, where QA/QC roles on large projects are a well-trodden path for Indian engineers with welding and NDT credentials.
Questions people ask
What is the salary of a quality engineer fresher in India?
On Highlisted in mid-November 2026, quality posts that stated pay had a median of about ₹4.0 lakh a year across all experience levels (61 posts); too few fresher posts stated pay for a separate figure. Supplier quality and auditing roles tend to pay more than inspection.
Is a QC job good for a mechanical engineer?
Yes, if you use it to learn how parts fail and how processes are controlled. QC leads to QA, supplier quality and management roles, and every plant needs those people. It becomes a dead end only if you stay in final inspection for years without taking on complaints, audits or projects.
Which certification is best for quality engineers?
It depends on the industry. Auto suppliers value IATF 16949 knowledge and the core tools; most industries value an ISO 9001 lead auditor certificate; Six Sigma Green Belt helps in process improvement roles; NDT Level 2 and welding inspection matter in construction, oil and gas. Pick the one your target employers name in their posts.
What is the difference between QA and QC?
QC inspects and tests the product to find defects. QA designs and audits the processes so defects don't happen. Most quality careers start in QC and move into QA.
