Prior to his move to Sentient Science, Shirley was CFO of GE Digital's intelligent platforms business. He has also held several roles in GE Healthcare since 2011.
At his new company, Shirley will "focus on growing Sentient Science and lead the company in filing an IPO planned for 2018".
"His years of experience scaling software companies will serve us well as we continue expanding in Europe and China, bringing more wind assets online each month," said Sentient Science CEO Ward Thomas.
"We're currently contracted for 20,000 wind turbines and anticipate growth to 50,000 by mid-2017. I'm confident that with Christopher's leadership, we'll be able to continue delivering on our rapid growth commitments and achieve IPO status in two years," Thomas added.
Sentient was valued at $100 million in October 2016, the firm said.
