JKSSB Junior Engineer (Mechanical) 2026: 127 Posts, Dates, Syllabus and Pattern

The Jammu and Kashmir Services Selection Board (JKSSB) published Advertisement Notification No. 10 of 2026 on 21 October 2026 for the post of Junior Engineer (Mechanical) in the Public Works (R&B) Department. This page sets out the facts from the notice, what the board has not yet published, and how to prepare.

Key facts from the notice

• Post: Junior Engineer (Mechanical), Public Works (R&B) Department, UT cadre, Pay Level 6 (₹35,400 to ₹1,12,400)
• Vacancies: 127 posts (open merit 51, SC 10, ST-1 13, ST-2 13, OBC 10, ALC/IB 5, RBA 13 and EWS 12)
• Applications open: 16 November 2026
• Last date: 15 December 2026
• Fee: ₹600, and ₹500 for SC, ST-1, ST-2, EWS and PwBD candidates, payable online only
• Selection: merit in the written (OMR) examination only, with no interview

Eligibility

• Qualification: a 3-year Diploma in Mechanical Engineering from a government-recognised institute, or a university degree in Mechanical Engineering, or AMIE Sections A and B (India)
• Age on 1 January 2026: at most 40 years for open merit, 43 for reserved categories and 42 for physically challenged candidates, with the ex-servicemen deduction in the notice
• Domicile: a valid Domicile Certificate of the UT of Jammu and Kashmir on or before the last date
• Certificates must be valid on the cut-off date, so check yours before 15 December

What the board has said about the paper

• The examination is objective, with multiple-choice questions
• Questions are set in English only
• Each wrong answer costs one-fourth of the marks for that question
• The syllabus will be notified separately on the board's website
• The date and centres will be notified separately

Topics to prepare while the syllabus is awaited

Technical papers for engineering posts usually carry most of the marks, with general awareness, English, reasoning and maths making up the rest. For this post our expected list for the technical part is: thermodynamics, fluid mechanics and machines, strength of materials, engineering mechanics, theory of machines, machine design, IC engines, refrigeration and air conditioning, heat transfer, power plants, manufacturing processes, machining, metrology, engineering materials and industrial engineering. This is our estimate from the usual diploma and degree syllabi, not the board's list.

A preparation timeline

• Now to 15 November: revise the core of each subject using the topic lists and take diagnostic tests
• 16 November to 15 December: apply during the window, and keep your documents ready
• After applying: move to timed sets and full mocks, and watch the board's website for the syllabus
• After the syllabus: adjust the plan to match the board's list and weights

Documents to keep ready

• Matriculation certificate with date of birth
• Diploma or degree certificate and mark sheets, or the AMIE certificate
• Domicile certificate valid on the last date
• Category certificate in the prescribed format, if you claim a reservation
• A recent photograph and your signature in the size the portal asks for

Study approach for diploma and degree holders

Diploma holders should revise the basics of each subject, since the board may set questions at the diploma level for the post. Degree holders should focus on speed, since they may know the theory but need practice for multiple-choice questions. Both should solve numerical problems by hand and memorise the standard formulas.

A weekly practice plan

• Monday and Tuesday: thermodynamics and fluid mechanics
• Wednesday: strength of materials and engineering mechanics
• Thursday: theory of machines and machine design
• Friday: manufacturing and materials
• Saturday: a timed mixed test
• Sunday: review and retest of errors

Negative marking

With a deduction of one-fourth of the marks, a wrong answer costs a quarter of a right one. In technical sections, you can often remove two options by checking units or limiting cases. Guess only after you have done so.

Practise

Our full-length mocks follow an expected pattern of 100 questions in 100 minutes with 40 technical questions and one-fourth negative marking. This split is our own and the board's syllabus will replace it. Start with the technical topic pages: thermodynamics MCQs, fluid mechanics MCQs, strength of materials MCQs, IC engines and refrigeration MCQs, theory of machines and machine design MCQs, manufacturing and machining MCQs, heat transfer and power plants MCQs and engineering materials and metrology MCQs.
