UPSC Engineering Services Examination 2027: 480 Posts, Full Eligibility and Application Guide

The Union Public Service Commission has opened one of its most closely watched recruitment cycles of the year. The Engineering Services Examination (ESE) 2027 notification, released on 16th September 2026, invites applications for 480 vacancies across four engineering disciplines: Civil, Mechanical, Electrical, and Electronics & Telecommunication. For engineering graduates aiming at a career in India’s premier technical services — think Indian Railways, Indian Ordnance Factories, the Border Roads Organisation, and several other central engineering cadres — this is the annual gateway exam that decides entry.

Online applications opened on 16th September 2026 and close on 6th October 2026. What follows is a complete breakdown of who can apply, how the selection process actually works, what the job pays, and how to submit an error-free application before the window shuts. Candidates who are beginning their preparation alongside the application process can also explore best APSC online coaching options to build a structured study plan.

What Is UPSC ESE, and Why Does It Matter?

The Engineering Services Examination is UPSC’s equivalent of the Civil Services Examination, but for engineering graduates. Candidates who clear it are inducted into Group A and Group B engineering services of the Government of India — roles that carry technical leadership responsibility in railways, defence production, telecommunications, power, and public works. It is a three-stage exam: a preliminary objective test, a mains examination with conventional (written) papers, and a personality test (interview), making it a fairly long haul from application to final appointment — typically stretching close to a year.

Notification Snapshot

Eligibility: Age Limit and Relaxations

To sit for ESE 2027, a candidate must have turned 21 but not crossed 30 as on 1st January 2027 — meaning the date of birth must fall between 2nd January 1997 and 1st January 2006. UPSC grants the standard relaxations on top of this base limit. Candidates preparing for competitive examinations in Assam can also explore APSC coaching Guwahati for structured preparation and exam guidance.

• SC/ST candidates get a 5-year relaxation.
• OBC-NCL candidates get a 3-year relaxation.
• Persons with Benchmark Disabilities (PwBD) get a 10-year relaxation.

Educational Qualification

Applicants need a recognised engineering degree — from a university set up by an Act of Parliament or a state legislature, or an institution deemed a university under the UGC Act, 1956. UPSC also accepts several professional-body equivalents in place of a university degree, including passing Sections A and B of the Institution of Engineers (India) exam, a recognised foreign engineering degree or diploma, the Graduate Membership exam of the Institution of Electronics and Telecommunication Engineers (India), and a couple of older aeronautical and radio-engineering qualifications that still appear in the fine print for specific posts.

Two service-specific exceptions are worth flagging for candidates eyeing niche postings. For the Indian Naval Armament Service (Electronics Engineering posts), an M.Sc. with Wireless Communication Electronics, Radio Physics, or Radio Engineering as a special subject also qualifies. For the Indian Radio Regulatory Service Group ‘A’, an equivalent M.Sc. or a Master’s in Physics with Radio Communication, Electronics, or Telecommunication as a special subject works as an alternate route.

Application Fee

Female candidates, and those from SC, ST, or PwBD categories, are exempt from paying any fee. All other candidates pay Rs 200, submitted online at the time of application. Candidates preparing alongside the application process can consider APSC online classes for structured lessons, regular practice, and guidance aligned with the examination syllabus.

Selection Process: What the Three Stages Actually Test

Preliminary examination — an objective-type test split into a general studies and engineering aptitude paper, and a discipline-specific technical paper. This stage is a qualifier; marks aren’t carried forward to the final merit.

Main examination — two conventional (written, descriptive) papers in the candidate’s chosen engineering discipline. This is where technical depth and the ability to structure long-form answers under time pressure really counts. Candidates looking for structured preparation support can also explore UPSC coaching in North East India for guidance on technical subjects, answer writing, and exam-

Personality test — candidates who clear the mains sit for an interview assessing communication, judgment, and suitability for a technical leadership role in government service.

Final selection and service allocation depend on the combined score across mains and the personality test, weighed against category-wise vacancies and the candidate’s service preferences.

How to Apply Online

1. Visit the official UPSC application portal and locate the Engineering Services Examination 2027 notification.
2. Register with a valid email ID and mobile number, then log in to start Part I of the application.
3. Fill in personal and educational details exactly as they appear on your certificates — mismatches here are one of the most common reasons applications get rejected later.
4. Upload a recent passport-size photograph and signature in the specified format and size.
5. Move to Part II, select your engineering discipline and preferred exam centre, and pay the application fee if applicable.
6. Review every field carefully before final submission — UPSC does not allow edits once the form is submitted.
7. Download and save a copy of the submitted form and the fee receipt for your records.

A Few Things Worth Doing Before You Apply

Keep scanned copies of your degree certificate, category certificate, and PwBD certificate (if applicable) ready in the correct format before you start the form — running out of time mid-application because a document needs resizing is a common, avoidable problem. It’s also worth cross-checking your discipline choice against the exact posts it opens up; Civil, Mechanical, Electrical, and Electronics & Telecommunication each feed into a different mix of departments, and switching later isn’t an option. Candidates can begin their APSC exam preparation alongside these application checks so they have enough time to cover the syllabus, revise key topics, and practise for the examination.
