Alan Kenny will step into the new role, which has been created due to the "strong growth" of the business, according to a statement.
The platform has in excess of $210 million in funds under administration and is receiving $25 million per month in net inflows.
"In the new role, Mr Kenny will be responsible for managing the business’ continuing strategic growth and product development, as well as overseeing its client services, governance requirements, and marketing and sales activities," said the statement.
Australian Unity funds management general manager Fiona Dunn noted Mr Kenny's "outstanding knowledge of platforms and their use by the financial advice profession".
"His experience in building successful products from the ground up will be a significant asset for the Federation business as it enters the next important stage of its development," added Ms Dunn.
Mr Kenny makes the move to Federation Alliance from AMP, where he was head of product solutions and pricing for the AMP SMSF business.
Before that, he was general manager, products and investment at Colonial First State.
