The hires are for newly created roles.
Sweta Chattopadhyay joined the manager of the £22bn (€28bn) UK Railway Pensions Scheme’s private markets team as a senior investment manager.
Matthias Eifert was appointed investment manager and will focus on fundamental equity analysis with a responsibility for managing concentrated equity portfolios.
The announcement of their appointments comes after Tony Guida, as previously reported, joined the manager’s alternative risk premia team in December from ERI Scientific Beta, an EDHEC-Risk Institute platform.
Chattopadhyay joins from Adveq, a global alternative investment firm.
Before then, she worked at the Universities Superannuation Scheme and ABN Amro.
Eifert joins from Macquarie Securities, having also previously worked for Bluecrest and Mainfirst.
The hires come after RPMI overhauled its investment strategy in connection with a transformation programme launched in 2013.
Ciarán Barr, RPMI investment director, said: “We are intent on delivering more value to our members by selectively increasing internal resources to manage and control more of the investment portfolios internally where it is efficient to do so.”
