The Delhi Jal Board (DJB) recruits Assistant Engineers and Junior Engineers (Civil) to manage Delhi's water supply, treatment and sewerage infrastructure. With environmental and hydraulics-heavy work, DJB AE/JE is an ideal central-capital posting for civil engineers who enjoy water-resources engineering.
Delhi Jal Board posts are specialised — candidates strong in environmental, hydraulics and water-resources engineering have a clear edge.
