Artemis Investment Management has hired Antonia Stirling from Standard Life Aberdeen as co-head of stewardship.
Stirling will share the role with Inez Oliver, who joined Artemis in 2005, and will report to chief investment officer Peter Saacke.
At Standard Life Aberdeen, Stirling was head of corporate stewardship, having joined the firm in 2010 from Deloitte. She is also an ambassador for industry diversity initiative The Diversity Project.
Artemis said the Stirling's appointment would help the firm to strengthen and develop the firm's stewardship and ESG strategies.
Mark Murray, senior partner at Artemis, said: "Very rightly, stewardship in general, and ESG issues in particular, are increasingly important aspects of investment management.
"I am delighted that we have been able to attract someone of Antonia's calibre to strengthen and develop Artemis' overarching strategy on stewardship; work with our investment teams to help embed ESG considerations in their investment processes; and improve the communication of our stewardship activities to our clients."
Stirling said: "I am very pleased to have joined Artemis. Its reputation as an active investment manager speaks for itself. In developing its ESG and stewardship activities, I will be working with Inez Oliver, my co-head, and other teams to build on what Artemis has already begun."
