Fields Wicker-Miurin, the London Stock Exchange's former head of strategy, is to join the board of Scor, the world's fifth biggest reinsurance company.
A fluent French speaker, Ms Wicker-Miurin is in demand over the Channel after the government's decision to impose quotas for female directors.
The American-born former banker and venture capitalist is also on the board of BNP Paribas, one of France's biggest banks. Scor is also on the hunt for another woman director.
Ms Wicker-Miurin said she was "delighted" to be joining Scor at "such an interesting time".
Reinsurers have recently increased in importance due to the number of natural disasters in recent years, such as the earthquakes in New Zealand and the Fukushima disaster. Insurers use the secondary market to help protect their balance sheets against huge pay-outs for damage caused by these events.
