Innes joined HM Treasury as a policy researcher. She worked with several ministers and held various roles across the civil service.[citation needed] She joined Rightmove as Director of Consumer Data, where she deployed artificial intelligence at scale and developed relationships with Amazon.[2] Innes joined Faculty, where she was made director of transformation and strategy and acted as an advisor for the World Economic Forum.[citation needed]
In 2023 Innes joined the Alan Turing Institute (ATI) as the chief executive officer.[3][4] In late 2024, her leadership was criticised by staff who to asked the board to intervene due to a lack confidence in the institute's executive leadership.[5] Furthermore, technology secretary Peter Kyle demanded an overhaul at the Turing Institute, including a change of leadership,[6] in July 2025. A month later it became public that staff had also sent a whistleblowing complaint to the Charity Commission in which they accuse the institute under Innes' leadership "of misusing public funds, overseeing a 'toxic internal culture, and failing to deliver on the charity's mission".[7]
On September 4, 2025 it was announced that Innes will step down as the CEO of the ATI.[8]
