Ted Jennings was named senior investment manager within RPMI Railpen's private markets team, a spokesman said.
The position is new. Mr. Jennings leads the defensive team and has responsibility for the firm's long-term income fund. The strategy, which launched in 2016, looks for returns from less liquid assets with more predictable cash flows.
RPMI Railpen manages the assets of the £28 billion ($36.6 billion) Railways Pension Scheme, London.
Mr. Jennings "brings valuable additional experience and expertise to our growing private markets team, which continues to be a core area of focus for RPMI Railpen," Paul Bishop, head of private markets, said in a news release.
Mr. Jennings joined from Aviva Investors where he was a portfolio manager for the alternative income solutions fund, the news release said. Aviva spokesmen could not immediately be reached for comment.
