BTSC JE EXAM 2025

The BTSC JE EXAM 2025, established to streamline technical recruitments across state departments, has once again demonstrated its commitment to merit-based hiring with the BTSC JE Notification 2025. Released on October 4, 2025, this short notice signals the start of a process aimed at bolstering Bihar’s public works, irrigation, and energy sectors. The recruitment targets Junior Engineers who will contribute to projects like road construction, water management, and electrical infrastructure—key pillars of the state’s development agenda under initiatives like Bihar Vikas Mission.

Eligibility remains accessible: a three-year diploma is the baseline, with B.E./B.Tech holders also welcome. Age relaxations cater to reserved categories, promoting equity. The selection blends academic merit with practical skills, awarding points for relevant experience—a nod to real-world readiness. As Bihar invests heavily in infrastructure (₹50,000 crore budgeted for 2025-26), these roles promise not just jobs but impactful contributions to flood control, power distribution, and sustainable development.

Vacancy Breakdown: BTSC JE EXAM 2025

BTSC’s vacancy distribution in 2025 is strategically aligned with Bihar’s technical demands. Totaling 2,747 posts, the lion’s share—2,591—goes to Civil Engineering, underscoring the state’s priority on civil infrastructure like bridges, dams, and highways. Mechanical follows with 70 spots, ideal for those skilled in machinery maintenance and industrial applications, while Electrical claims 86, focusing on power systems and electrification projects.

Here’s a tabulated overview for clarity:

Reservations apply per Bihar norms: 16% SC, 1% ST, 18% EBC, 12% BC, 10% EWS, and 35% horizontal for women. PwD and ex-servicemen get 4% each. This ensures broad access, but competition will be stiff in Civil due to higher numbers—expect 50,000+ applicants branch-wide based on past trends.

For aspirants, this means tailoring prep to branch-specific roles. Civil JEs might handle site surveys and estimations, Mechanical ones machinery overhauls, and Electrical experts grid maintenance.
