He is a 1991 batch IAS officer of the Haryana Cadre. He has been repeatedly transferred by various state governments in his home cadre of Haryana after he exposed corruption in the departments he was posted in. Khemka was posted as Secretary to the Govt. of Haryana, Deptt. of Archives and Archaeology on 4 April 2013. He was also given the charge of DG Archives and Archaeology on 26 April 2013.

While he is seen by many as a whistleblower who exposes wrongdoings in departments where he is posted, the officer has also used the Right to Information Act (RTI) to ferret out information relating to undue favours availed by some of his colleagues, irrespective of their position in the pecking order in the state .
