Senior Protocol Engineer
About The Position
We're partnering with Quant, a global leader in digital transformation and technology solutions, seeking a Senior Protocol Engineer to join their team. Quant is a leading provider of programmable money infrastructure, and their technology lets banks issue, move and settle tokenized deposits around the clock, automatically and securely, while staying connected to the systems they already run on. It is already deployed in regulated environments with central and commercial banks in the UK and around the world, including work on the digital pound and the digital euro. The Clearing House, whose networks clear and settle more than $2 trillion a day, has now selected Quant to power its On-Chain Money Initiative: a new interoperable payments network that will let financial institutions of all sizes clear and settle tokenized deposits, with connectivity to the RTP® and CHIPS® networks. Quant's technology provides the network's interoperability, orchestration and transaction-management layer, enabling payments that settle immediately and transactions that trigger automatically once agreed conditions are met. Through their Tokenized Deposits-as-a-Service solution, banks of any size can join without building new infrastructure themselves. The network is expected to become available to participating institutions in the first half of 2027, with use cases across corporate treasury, liquidity management, cross-border payments and digital asset settlement. They are building the New York team that will run it.
