• Our Investments business is a specialist asset manager that focuses on areas where we have both strength and scale to capitalise on the key themes shaping the market, through either public markets or alternative asset classes.

An inclusive way of working

Whatever way you like to work, if you have the talent and commitment to join our team, we’d like to hear from you.

At Aberdeen we’ve adopted a ‘blended working’ approach. This approach combines the benefits of face-to-face collaboration, coaching and connecting in our offices with the flexibility of working from home. It enables colleagues to find a balance that works for their roles, their teams, our clients and our business.

An inclusive culture, where diverse perspectives drive our actions, is at the core of who we are and what we do. If you need assistance with your application, or a reasonable adjustment to your interview arrangements – for example, because you are neurodivergent, or have a physical, sensory, cognitive, mental, visible or invisible disability – please let us know and we’ll be happy to help.
