Sanjay Bangar has been appointed India assistant coach and Bharat Arun will take over the role of bowling coach, while Rahul Dravid and Zaheer Khan have landed consultancy roles.
Bangar was previously employed as batting coach of the national team, but steps up to become new head coach Ravi Shastri's number two.
Shastri recommended Arun to take over as bowling coach and it was confirmed on Tuesday he has got his wish.
Bangar and Arun have followed Shastri in signing two-year contracts, which will run until the end of the 2019 ICC Cricket World Cup in England and Wales.
Legendary batsman Dravid and former paceman Zaheer join the board as consultants.
Shastri said: "I have spoken to both [Dravid and Zaheer] the individuals as good as three or four days ago.
"They were fantastic cricketers for India, and their inputs will be invaluable. They will be on board once they have spoken to the authorities concerned, so there are no issues on that."
