Mangalore Refinery and Petrochemicals Limited Assistant Engineer, 'E2' Grade 2026

MRPL's Assistant Engineer E2 role targets fresh engineering graduates or those within the first few years of employment. The three specialisations, mechanical, Electrical, and Chemical, each require a specific engineering degree. Mechanical engineers maintain equipment, compressors, and rotating machinery. Electrical engineers oversee power systems, control panels, and instrumentation. Chemical engineers design and optimise process flows, quality control, and safety systems in refinery operations.

Since age limit is not specified in the notification, contact MRPL HR or check the official job portal carefully, age may be capped at 25–30 years for fresh graduates, or higher for in-service candidates. Use this age calculator to confirm your eligibility once the age criterion is confirmed.

• Pay Band: ₹50,000–₹1,60,000 gross (E2 grade, typical for Assistant Engineer entry in ONGC subsidiaries)
• In-hand estimate: ₹42,000–₹1,35,000 after NPS (~10%) and income tax
• Starting basic pay: Typically ₹50,000–₹55,000; increments annual with performance appraisal

E2-grade Assistant Engineers in MRPL can expect progression to Senior Engineer (E3) within 6–8 years, then Manager (E4) within 15 years of service. The wide salary band reflects seniority steps within the grade. After NPS deduction (~10%) and income tax, fresh joiners take home approximately ₹42,000–₹50,000 monthly initially. Compared to private refinery operations (Reliance, Essar), MRPL offers superior job security, pension, gratuity, and medical benefits, offsetting slightly lower starting salaries. Use this salary calculator to estimate in-hand salary based on your age and grade.

• Wrong degree branch code: MRPL has distinct codes for Mechanical, Electrical, and Chemical. Selecting the wrong code (e.g., choosing Electrical when you're a Mechanical engineer) will result in outright rejection. Match your degree certificate exactly.
• Photo/signature format violations: Photos with coloured background, glasses, or not fully showing face are rejected at portal verification. Signature must be original handwriting, not printed or typed. Ensure JPG/PNG format, not BMP or TIFF.
• Missing or incomplete degree certificate scan: Document verification requires clear scans of the entire certificate (both sides if issued on two pages). Partial scans or blurry images cause rejection at DV stage.
• Duplicate applications: Applying twice (even with different email IDs) flags your profile for rejection. Submit only once per specialisation.
• Fee payment not linked: If you pay the fee but don't receive confirmation email within 30 minutes, contact MRPL HR immediately, unpaid applications are auto-rejected on closing date.
• Name mismatch: Your application name must exactly match your degree certificate and Aadhaar. Initials, middle names, or spelling variations cause document rejection at verification.

Once you pass all three interview rounds and document verification confirms your eligibility, MRPL HR will issue a provisional appointment letter (typically within 2–3 weeks of final merit list). You will then undergo a medical fitness examination at an ONGC-designated hospital. Assuming you clear the medical, you receive a final appointment letter with a joining date (usually 1–2 months from the letter date). Your posting location will be Mangaluru (MRPL head office and main refinery), though ONGC subsidiaries occasionally post engineers to other facilities for project-based assignments after 3–5 years.

On joining, you undergo a 3–6 month induction and on-the-job training (OJT) where you work under a senior engineer's mentorship. During this period, your performance is assessed; satisfactory completion leads to confirmation in the E2 grade. Total end-to-end timeline from final interview to first salary: approximately 4–6 months. Once confirmed, you are eligible for annual increments, promotion to E3 (Senior Engineer) within 6–8 years based on performance and seniority, and full ONGC pension/gratuity benefits.

Mangalore Refinery and Petrochemicals Limited (MRPL) was established in 1991 and is one of India's largest crude oil refineries, located in Mangaluru, Karnataka. It operates under the administrative control of Oil and Natural Gas Corporation (ONGC) and holds the status of a Schedule 'A' Mini Ratna Central Public Sector Enterprise (CPSE). MRPL processes approximately 20 million metric tonnes of crude oil annually, producing petrol, diesel, jet fuel, LPG, naphtha, and petrochemical feedstocks that supply the Indian energy and chemical sectors. The refinery employs over 3,500 permanent staff and operates with state-of-the-art process units including fluid catalytic crackers (FCC), hydrotreating facilities, and speciality chemical plants.

MRPL is known for its operational excellence, safety culture, and technical innovation in refinery technology. As an ONGC subsidiary, MRPL offers employees pension security, job stability, and structured career progression, hallmarks of India's central government enterprises. The organisation actively recruits engineering graduates annually for production, maintenance, and planning roles across all three engineering disciplines. MRPL's workplace is unionised and follows defined career paths with transparent promotion timelines, a major advantage for those seeking long-term employment in core process industries.

An Assistant Engineer at MRPL is an entry-to-mid-level technical position responsible for the safe, efficient operation and maintenance of refinery process units. Mechanical engineers oversee rotating equipment (compressors, pumps, turbines), pressure vessels, piping systems, and mechanical heat exchangers, performing condition monitoring, failure analysis, and maintenance planning. Electrical engineers manage power distribution, motor control centres, instrumentation panels, safety shutdown systems, and distributed control systems (DCS), ensuring continuity of plant operations. Chemical engineers focus on process optimisation, reaction monitoring, product quality assurance, waste treatment, and process safety, working closely with operations teams to meet production targets and regulatory compliance (SPCB, CPCB, and OHSAS standards).

Day-to-day duties include shift-based monitoring of assigned units, troubleshooting equipment faults, participating in preventive maintenance rounds, mentoring junior technicians, and generating technical reports. The role is predominantly on-site (field-based) for the first 2–3 years, involving exposure to high-temperature, high-pressure, and hazardous chemical environments, full safety gear is mandatory. Advancement to Senior Engineer (E3) comes after 6–8 years of demonstrated technical competence, project delivery, and team leadership. Assistant Engineers are non-uniform staff but required to wear hard hats, safety shoes, and chemical-resistant gear during plant visits, standard for central government refinery operations.
