I have worked with One Search on a number of occasions, both in recruiting new positions, and as a candidate myself. I have found them to be a pleasure to work with and, whichever side of the recruiting process I’ve been on, they have taken the time to understand what I am after from either a new role or recruit. As candidate, I received lots of useful advice and encouragement, and as a recruiter, I have received a strong range of candidates accompanied with honest feedback and appraisals, all of which has helped make the process as streamlined as possible.

As we have built the Edmond de Rothschild AM Infrastructure Debt business since 2014, hiring top, diverse, adaptable and ambitious talent has been the key priority to provide our investors with the best investment portfolios and service. One Search, led by the visionary Dan McCarthy, has been invaluable in this regard, working as a trusted partner and helping me, starting from scratch, to build a Franchise now consistently in the top 10 globally and growing.

It had been obvious to us for many years that the only way real gender diversity in our sector was going to be achieved and sustained was if more young women wanted to come into it.
After years of talking heads getting us nowhere in this regard (female entry level hovered between 12-18% for ten years in the decade 2008-2018), in 2018 we decided to do something about it.
Introducing the future
Our sister company, Infrassocs is here to revolutionize junior level hiring across infrastructure and the energy transition. We identify the most talented juniors and partner with them as they navigate their early career.
