HQLAᵡ Ops Engineer

An exciting opportunity exists for an Ops Engineer/developer to help build HQLAx’s new collateral exchange platform which will use R3’s Corda distributed ledger (‘blockchain’) technology to digitise baskets of assets and create a standardised token lending marketplace to help market participants redistribute liquidity more effectively and more cost efficiently.

HQLAx is a partnership of financial market veterans focused on providing corporate and bank treasurers with a cost effective, standardised, transparent and scalable market solution to transfer liquidity more efficiently.

  • A prototype version of the HQLAx securities lending platform was originally built in 2017 using Corda via a collaboration of 5 banks, R3, and HQLAx.
  • Subsequently, an early version of the platform was used to execute a live transaction between 2 banks at the start of 2018.
  • In April 2018, Deutsche Börse Group and HQLAx announced a partnership to build the HQLAx platform on the R3 Corda Blockchain Platform.
  • And more recently, Deutsche Börse Group announced that it expanded its partnership with HQLAx by acquiring a minority stake in HQLAx.
