Rudnitsky, who has been with Wyndham for almost seven years and also worked for foodservice companies Kraft, Nabisco and Pillsbury, will join the Dolce board on 8 December.
Rudnitsky, who will report to Dolce chairman Andy Dolce, will be charged with developing the group's leisure business. Earlier this month, Dolce revealed plans to expand in the UK.
Welcoming Rudnitsky to the group, Dolce said: "His track record for building collaborative teams, identifying opportunities and developing acquisition strategies is exactly what Dolce Hotels and Resorts needs to continue its position as the leading hospitality specialist in the global meetings market."
