Hildebrand, who stepped down in January after being caught up in a scandal over foreign exchange trades done by his wife, will be joining the new Blavatnik School of Government.
"We look forward to Dr Hildebrand's advice and guidance in the school and in particular in helping us shape research with a practical edge," said Professor Ngaire Woods, the school's dean.
"Dr Hildebrand brings a rich experience not just of government and financial markets, but also of research and teaching. We are delighted he will be joining the school."
The Blavatnik School was founded in 2010 and will be admitting its first 30 students in September.
Press reports had alleged that Hildebrand's wife Kashya profited after buying $504,000 last August.
The trade was done just weeks before an intervention by the Swiss National Bank to halt the rise of the franc -- a move that saw the dollar rise significantly against the Swiss currency.
Hildebrand has a doctorate in international relations from Oxford and is an honorary fellow of the university's Lincoln College.
