The official notification consolidates both fresh current vacancies and unfilled backlog vacancies from previous recruitment cycles into the advertised total of 60 posts. Notably, certain PwBD positions (such as Orthopedically Handicapped in Mechanical and Multiple Disabilities in Electrical) are being re-advertised as a 3rd Attempt. If eligible candidates from the specified PwBD sub-categories are not available, CPCL may consider other identified PwBD categories as permissible under statutory guidelines.
👩💼 Can Women Apply for CPCL Recruitment 2026?
The official notification specifies that due to hazardous operations, continuous process requirements, and specific shift patterns governing refinery processing units, women candidates are presently not being considered for the Production discipline (CPCL01).
Women candidates who satisfy the prescribed qualifications and 3-year experience criteria are eligible to apply for the following three technical positions:
- CPCL02 — Junior Engineering Assistant-IV (Mechanical)
- CPCL03 — Junior Engineering Assistant-IV (Electrical)
- CPCL04 — Junior Engineering Assistant-IV (Instrumentation)
Mandatory 3-Year Post-Qualification Work Experience
Unlike entry-level fresher recruitments, all four Junior Engineering Assistant positions require a minimum of 3 years of relevant post-qualification work experience acquired after obtaining the qualifying Diploma or B.Sc. degree:
Production (CPCL01) Experience
Relevant experience in continuous process operations of Refining, Petrochemical, Chemical, Fertilizer, or Gas Processing plants, handling equipment such as fired heaters, distillation columns, high-pressure reactors, heat exchangers, pumps, compressors, effluent treatment plants, and pressurized tank storage.
Mechanical (CPCL02) Experience
Hands-on maintenance experience involving rotary and static equipment: process pumps, centrifugal/reciprocating compressors, steam/gas turbines, boilers, heat exchangers, column vessels, piping networks, safety relief valves, and heavy storage tanks in eligible process plants.
Electrical (CPCL03) Experience
Maintenance and operational experience with HT/LT switchgear, power transformers, AC/DC motors, emergency diesel generators, UPS systems, industrial battery banks, and Variable Frequency Drives (VFDs), with proficiency in electrical schematic troubleshooting.
Instrumentation (CPCL04) Experience
Maintenance and calibration of process control instrumentation: pneumatic/electronic transmitters, smart control valves, DCS/PLC hardware, P&ID logic diagrams, shutdown interlocks, and industrial analytical instruments.
🛠️ Does Apprenticeship Count as Experience?
Yes. The official notification explicitly affirms: "Apprenticeship Training under the Apprenticeship Act, 1961, shall be considered as work experience." However, candidates must still ensure that the combined duration of their apprenticeship and subsequent employment meets the mandatory 3-year relevant experience requirement in the prescribed technical field.
Large Industrial Establishment Experience Verification
CPCL defines a "Large Industrial Establishment" as an operational industrial/manufacturing unit whose capital investment in plant and machinery exceeds ₹10 Crores. Candidates claiming experience from private sector industries must produce supporting documentary proof, such as the relevant page of the employer's last published Annual Report/Balance Sheet, or contractor work orders clearly corroborating the investment threshold.
🚫 Are B.E. / B.Tech Graduates Eligible for JEA-IV?
No. Candidates possessing higher professional qualifications are strictly ineligible.
The official notification explicitly states that candidates who possess or are pursuing higher professional degrees, such as B.E., B.Tech, MBA, CA, LLB, MCA, or equivalent qualifications, are not eligible for Junior Engineering Assistant positions.
CPCL mandates full disclosure of academic qualifications. Suppression of higher qualifications or false declarations will lead to summary cancellation of candidature and termination of employment if detected at any stage.
Reservation, PwBD & Ex-Servicemen Guidelines
OBC-NCL & EWS Validity
OBC (Non-Creamy Layer) and EWS candidates must possess valid certificates issued on or after 01 April 2026 in the prescribed Government of India format. Creamy-layer OBC candidates are not entitled to reservation.

CPCL Percentage Calculation & CGPA Conversion Rules
• All-Semester Aggregate Rule: Percentage must be computed by calculating marks across all subjects and semesters/years.
• No Rounding-Off: CPCL strictly ignores fractions. For instance, 59.99% will be treated as less than 60% and is ineligible for unreserved positions.
• CGPA / OGPA Conversion: Where marks are awarded in grades/points, candidates must convert them to percentage according to the formula prescribed by their institution and produce the official conversion certificate at document verification.
Key Cautionary Guidelines for Applicants
Each applicant can apply for only ONE position code. Submitting multiple forms will result in cancellation of candidature without fee refund.
The Computer Based Test is tentatively scheduled to be conducted exclusively in Chennai. Travel arrangements must be planned accordingly.
Candidates working in Central/State Government departments, PSUs, or autonomous bodies must produce a formal No Objection Certificate (NOC) at document verification.
