CPCL Non-Executive Junior Engineering Assistant-IV Recruitment 2026 — 60 Posts in Chennai

CPCL Recruitment 2026 — Important Dates & Application Fee

Apply Online from 14 August to 11 September 2026 — CBT in Chennai

The application window is from 14 August to 11 September 2026 (23:59 Hrs). That gives you about 28 days. But do not wait till the last date — CPCL portal can slow down with heavy traffic. And the CBT is tentatively in September or October 2026, in Chennai only. So plan your travel accordingly. The admit card will be released about 10 days before the CBT. And here is a practical tip — keep checking cpcl.co.in regularly for updates because CPCL does not send individual notifications. The age, qualification, and experience are all reckoned as on 1 July 2026. So make sure you meet the eligibility criteria before that date.

Tip: Apply well before the closing date. CPCL does not accept late applications under any circumstances, and payment reconciliation can take time.

Application Fee — ₹500 for General/OBC/EWS, Exempted for Others

The application fee is ₹500 for General, EWS, and OBC candidates, plus applicable bank charges. And SC, ST, PwBD, Ex-Servicemen, and Women candidates are fully exempted — no fee at all. Payment is online only through SBI e-Pay — Debit Card, Credit Card, UPI, or Net Banking. No other payment mode is accepted. And once paid, the fee is not refundable under any circumstances. So before paying, make sure you are applying for the right post because you can apply for only one post. If you apply for more than one post, only the first application is considered. And carrying multiple applications can lead to disqualification. So be careful and apply for the post where your experience matches best.

CPCL Recruitment 2026 — Vacancy & Eligibility Details

60 Posts — Production 40, Mechanical 10, Electrical 5, Instrumentation 5

So there are 60 posts in total. Production has the most — 40 posts. Then Mechanical has 10, and Electrical and Instrumentation have 5 each. See, Production is the biggest department because refinery operations need maximum manpower. And the category-wise break-up — UR has 26, OBC has 15, SC has 9, EWS has 5, and ST has 0. So if you are from OBC or SC category, your chances are decent because the reserved vacancy is good. And there are backlog vacancies too — 2 SC, 3 OBC, and 3 PwBD posts that were unfilled in previous recruitments. One thing to note — women cannot apply for Production posts because of hazardous refinery operations and shift work. But Mechanical, Electrical, and Instrumentation are open for women. So if you are a woman candidate with Diploma in Mechanical, Electrical, or Instrumentation, you can apply.

Diploma Plus 3 Years Refinery Experience — Higher Qualifications Make You Ineligible

The qualification is specific — you need 3-year Diploma in the relevant discipline from a recognized institution, with minimum 60% aggregate for General/OBC/EWS or 55% for SC against reserved posts. And you must have minimum 3 years post-qualification experience in refinery, chemical, petrochemical, fertilizer, or similar continuous process industry. See, here is the important part — if you have higher qualifications like B.E./B.Tech, MBA, CA, LLB, or MCA, you are ineligible. So this post is exclusively for Diploma holders. And Diploma via lateral entry (Class XII Sc/ITI admitted to 2nd year) is also eligible, but the percentage must be on the aggregate of 4 semesters. The age limit is 30 years as on 1 July 2026. SC/ST gets 5 years relaxation, OBC gets 3 years, PwBD gets 10 years, and Ex-Servicemen get service period plus 3 years (max 50 years). So check your eligibility carefully before applying.

CPCL Recruitment 2026 — Salary & Job Profile

IDA ₹25,000 – ₹1,05,000 Plus DA, HRA, PF, Gratuity, Medical — Non-Supervisory Grade IV

The salary is on IDA pay scale ₹25,000 to ₹1,05,000. Starting basic is ₹25,000 with no pay protection. See, this is actually good for a Diploma-level post in a Navratna PSU. And on top of basic, you get Dearness Allowance (DA), HRA or Self-Lease, Provident Fund, Gratuity, LTC/LFA, Medical Reimbursement, and Superannuation benefits. So the in-hand salary will be decent once all allowances are added. And since CPCL is a Navratna PSU, the working conditions and facilities are good. The job is in Chennai, at the CPCL refinery with 10.5 MMTPA capacity. So you will be working in a major industrial setup. And the cadre is Non-Supervisory Grade IV — which means you start at the bottom but can grow within the corporation. If you are looking for a stable PSU job with good salary, this is worth trying.

What You Will Do as Junior Engineering Assistant-IV

• Operate and monitor production equipment in the refinery
• Maintain rotary equipment — pumps, compressors, turbines
• Handle electrical maintenance — motors, transformers, switchgear
• Work on process control instrumentation and field instruments
• Read P&ID drawings and generate calibration reports
• Troubleshoot control circuits and maintain DCS/PLC systems
• Follow safety protocols in hazardous refinery environment
• Work in shifts — refinery operates 24/7, 365 days

And one thing — the work is shift-based because refinery runs round the clock. So be prepared for night shifts and working on holidays. That is the nature of refinery jobs. But the pay and benefits compensate for it.
