About IES Mechanical Engineering

Mechanical engineering is a discipline of engineering that applies the principles of physics and materials science for analysis, design, manufacturing, and maintenance of mechanical systems. IES Mechanical Engineering is the branch of engineering that involves the production and usage of heat and mechanical power for the design, production, and operation of machines and tools. It is one of the oldest and broadest engineering disciplines. The IES Mechanical Engineering relies on your understanding of the core concepts involved in mechanics, kinematics, thermodynamics, material science and structural analysis. Mechanical engineers use these core principles along with tools like computer-aided engineering and product lifecycle management to design and analyze manufacturing plants, industrial equipment and machinery, heating and cooling systems, transport systems, aircraft, watercraft, robotics, medical devices and more.

Pattern for IES Mechanical Engineering

A combined competitive examination is conducted by the Union Public Services Commission (UPSC) for recruitment to the Indian Engineering Services. The Examination constitutes of a written examination followed by an interview for personality test.
Every IES exam is divided into two sections -
Paper I & Paper II .
While paper I remains common for all the branches/streams of engineering, the paper II is specialized with respect to the branch of engineering students.

IES jobs for Mechanical Engineering

Indian Engineering Services(IES) include technical and managerial services for government of India. The pay scale of Indian Engineering Services is as high as the pay scale of IAS officers. After 7th pay commission, an IES officer with their esteemed cadre receives more benefits along with high salary and varied allowances and benefits. The recruitment of qualified candidates are made under the following sectors:

  1. Indian Railway Service of Mechanical Engineers
  2. Indian Railway Stores Service
  3. Central Water Engineering Service
  4. Indian Ordnance Factories Service
  5. Indian Naval Armament Service
  6. Assistant Executive Engineer (in Ministry of Defence)
  7. Assistant Naval Store officer Grade I in Indian Navy
  8. Central Electrical & Mechanical Engineering Service
  9. Assistant Executive Engineer (in Border Roads Engineering Service)
  10. Mechanical Engineer (in Geological Survey of India)
