TreasurySpring is the product of an obsession with fixing the fundamental structural problems in money markets. Our fascination with the sector began painfully, during the Global Financial Crisis of 2008, where we had a front-row seat to watch the evaporation of liquidity in fixed income and the near collapse of the entire short-dated funding markets.

We have been on a mission to help deliver more sustainable solutions for the money markets ever since, and we launched TreasurySpring in 2018 to offer institutional clients a single gateway to the broadest range of the best risk-adjusted cash investment options. As a fast-growing London-based financial technology company, we deliver a unique solution to a global multi-trillion-dollar problem, delivered globally from our offices in London and New York.

Our regulated Fixed-Term Fund platform delivers new digital pipelines to connect cash-rich firms to institutional borrowers. Clients include large Private Equity funds, Asset Managers, listed Corporates, high-growth tech companies and many more.

The role: Senior Backend Engineer

Join our lean UK-based technology team as a Senior Backend Engineer, where you'll play a pivotal role in the development of our systems. Working closely with the CTO and Head of Software Engineering, you'll have the opportunity to make a significant impact within our growing fintech business. This role offers the flexibility of remote work alongside visits to our offices in Mayfair, London.

Our proprietary technology platform handles billions of dollars worth of our customers' investments every day, capturing all client orders and managing the entire investment cycle. Our backend services are built in [typed] Python3, backed by a Postgres database. This includes a proprietary workflow engine built around a Scheme-based workflow notation.

Our frontend systems include our clean, simple web portal for client order capture and reporting, built in TypeScript and React; with server-side REST and GraphQL APIs written in Python3.
