Rubicon Infrastructure Advisors hired Sonia McMillan as a managing director and general counsel, the firm announced.
McMillan, who previously led InfraRed Capital Partners’ North America platform, will work out of Rubicon’s New York office but will support the firm’s global operations. She will be tasked with providing legal and strategic advice on deals across Rubicon’s Dublin headquarters and its offices in New York, London, Madrid and Bogota.
McMillan worked at InfraRed from July 2010 to September 2017 and was based out of the New York office. She was tasked with executing equity investments, including projects in North and South America, the Middle East, Europe and Australia. She helped InfraRed enter the South American and Israeli markets, and worked on the London-based firm’s first deals in North America.
“This appointment is a key role for the firm and she will form an integral part of our Global Leadership team.” Rubicon’s CEO Conor Kelly said. “Her extensive global experience in infrastructure investing and asset management along with her extensive legal and operational credentials will help to drive continued growth momentum firm-wide.”
Before joining InfraRed, McMillan worked from 2006 to 2010 for Allen & Overy, where she was a senior associate in the law firm’s energy and infrastructure group. Before that, she worked in the Melbourne offices of Phillips Fox Lawyers, which is now DLA Piper.
Rubicon has used a series of high-profile hires this year to boost its energy and infrastructure practice. Last month, the company brought on John Kirwan, previously Scotiabank’s global head of infrastructure. In June, Rubicon hired former CohnReznick Capital President Robert Sternthal to lead its North American practice.
The firm also opened an office in Bogota this fall and plans to open another in Sydney in 2019.
