Michelle McGregor Smith has announced her intention to retire from British Airways Pensions Investment Management (BAPIM) after over three decades working with the schemes.
She will step down as chief executive on 30 August 2019, 14 years after she took up the position, with the asset management arm now seeking a senior investment professional.
She had started at the firm as an equities analyst for the airline's schemes, with total assets now amounting to around £25bn.
In an internal note to staff, BA Pensions chief executive Fraser Smart said: "The family culture of the business we have today wouldn't exist without Michelle's presence and contribution so it goes without saying how much we will miss her."
McGregor Smith will remain "available" to provide any further support after her departure while the search for her successor continues.
A series of celebration events will be held over the course of the summer with both staff and trustees directors to thank McGregor Smith for her "substantial contribution", Smart added.
She joined BAPIM in 1988 after graduating from City University Business School and, since then, has worked as a portfolio manager and head of UK equities before her current role.
