About the DRDO JRF walk-in in Bengaluru
- Research on vacuum electronic devices, such as microwave tubes
- Work that can touch materials, ultra-high vacuum, electromagnetics and microwave design
- Simulation with particle-in-cell and computer-aided design tools
- A written test and the interview happen on the same day
The ad describes the research field. It does not list day-to-day duties.
Why this role matters
Few places in India build high-power microwave tubes, and DRDO trains most of the people who do. Two to four years here give hands-on work with vacuum devices that most university labs cannot offer.
Eligibility
- B.E./B.Tech in Electronics, EI, ECE, ET or EEE in first division, with a valid NET or GATE score; or
- M.Sc. in Electronics in first division, with NET; or
- M.E./M.Tech in Electronics, Power Electronics or Electrical Engineering, with first division at both graduate and postgraduate level
- Age: not more than 28 years. SC/ST/PH get up to 5 years of relaxation and OBC get 3 years
- Indian nationals only
Bring the original caste certificate if you claim a reservation. Candidates with a disability should bring a medical certificate from a government hospital or medical board. Government and PSU staff need a no-objection certificate. No travel allowance is paid. The selection panel stays valid for one year.
Pay and duration
- ₹37,000 a month plus House Rent Allowance as per rules
- Tenure of 2 years, which may be extended for up to 2 more years

How to prepare for this application
- Revise microwave basics: transmission lines, waveguides, S-parameters, resonant cavities and power amplifiers.
- Know how a tube works: read up on travelling-wave tubes, klystrons and magnetrons, and how an electron beam gives energy to an RF wave.
- Brush up on vacuum and materials: ultra-high vacuum, cathodes, and why outgassing matters in a sealed tube.
- Mention simulation tools you know: CST, HFSS, COMSOL or any particle-in-cell code. Be ready to explain one model you built.
- Plan the day: the test and interview are on the same day, so carry all originals and copies. See more JRF jobs.
