Job overview
Larsen & Toubro is hiring a Manufacturing Engineer Assembly Testing for its Coimbatore location in Tamil Nadu. The role covers assembly documentation, factory acceptance testing and on-site testing at customer plants.
Coimbatore’s mix of engineering workshops and large plants gives candidates many options, and employers there value hands-on skill. The listing marks this opening as on-site, so you should be ready to work from the location every working day.
What the Manufacturing Engineer Assembly Testing will do
The listing describes the day-to-day work in these main points:
- Prepare assembly process sheets and check sheets with tolerances, torque values and sequences.
- Check links between mechanical structures, sensors, PLC hardware and wiring before testing.
- Run factory acceptance tests, including dry runs of movements, pneumatic stroke limits and basic PLC sequences.
- Validate sensor repeatability, signal quality, ESD grounding and safety interlocks before dispatch.
- Lead site acceptance tests at customer plants in Chennai, Bangalore and Hosur.
Expect the real workload to depend on the programme or shift you join.
Eligibility and experience
The employer does not fix one degree in the part we reviewed, so read the full text on its portal for the exact branch. Years of experience are not spelled out, so your projects, skills and attitude will carry more weight in the screening.
Skills that will help you
Recruiters will likely look for these abilities first:
- Reading of drawings and wiring schemes.
- Basic PLC and sensor knowledge.
- Willingness to travel to customer sites.
- Clear test reporting.
Back each skill with one short example, because interviewers usually test the claims on your CV.
The employer keeps coming back to factory acceptance testing, PLC and sensor checks and site acceptance testing. Treat them as keywords for your CV and your interview answers.
Who should apply
It fits engineers who enjoy hands-on testing and customer-site work more than a desk-only job. It is less suitable for candidates who are only looking for a short-term job with no learning.
A typical working day
Most days you will be expected to prepare assembly process sheets and check sheets with tolerances, run factory acceptance tests and lead site acceptance tests at customer plants in Chennai. The mix changes with the project phase and the shift. Treat this as a typical picture rather than a fixed timetable, since priorities move from week to week.
How to prepare for the interview
Plant interviews focus on safety, process discipline and practical thinking. Be ready to explain how you follow a work instruction and what you do when a process drifts off target.
Prepare a short introduction that links your studies, your experience and the duties of this job in under a minute. One likely question is how you would check links between mechanical structures. Another may ask how you would validate sensor repeatability. Spend extra time on factory acceptance testing, PLC and sensor checks and site acceptance testing, because the listing points to them.
Resume tips for a Manufacturing Engineer Assembly Testing application
Add safety training, 5S, Kaizen or ISO exposure under a separate heading. Keep the page clean and easy to scan.
Save the file as a PDF with your name and role in the file name, so it is easy to find later.
Use the words of the listing where they are true for you. If the employer writes factory acceptance testing or PLC and sensor checks, make sure those exact words appear in your CV. Give proof for reading of drawings and wiring schemes, and for basic PLC and sensor knowledge, with a project, a figure or a result next to each.
Career growth after this role
Good performers in manufacturing get chances to train others, lead a line and later manage a full area. Keep a record of your results each quarter. It makes promotion talks and future job searches much easier.
How fast you move up depends on Larsen & Toubro and on your results, so ask what the typical path looks like. Asking about onboarding and training shows genuine interest.

- How does the team share knowledge and handle handovers?
- What safety and skill training is given during induction?
- What qualities make someone successful in this team?
- Which line or product family will I work on first?
Write the answers down, because they help you compare this job with other offers.
Common mistakes to avoid
Avoid speaking badly about a former employer. Keep your answers calm and focused on what you want to learn next.
Avoid sending repeated applications with changing details to Larsen & Toubro. One careful application is better than several rushed ones, and quick replies to calls help your chances.
