Senior Product Engineer

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. Learn more about why we do what we do here . The role: Senior Product Engineer We’re looking for a Senior Product Engineer to help redefine how institutions manage cash. You’ll build software that replaces manual treasury processes and legacy infrastructure with intuitive products used by leading investors, corporations and financial institutions. You’ll own customer problems end to end, from understanding the workflow through to designing, building, shipping and improving the solution. You should already be comfortable working with Python, React and TypeScript . You may have strengths in one area, but you’ll be expected to contribute across the stack and become increasingly full-stack over time. You’ll work directly with Product, Design, customers and domain experts to understand customer needs, shape the right solution and measure its impact after release, not simply implement completed designs or pre-defined tickets. AI is fundamental to how we build software. We expect engineers to orchestrate coding agents, rapidly prototype ideas, automate repetitive work and continually evolve their engineering workflow as the technology advances. AI should increase your leverage, not replace your judgement. You remain accountable for everything that reaches production. What you’ll do: Responsibilities Build and ship high-quality features across our React, TypeScript and Python stack, taking ownership from discovery through to production and continuous improvement. Help reimagine how modern institutional treasury works by replacing manual processes and legacy systems with intuitive software. Work directly with customers to understand their workflows, pain points and goals, using those insights to shape product and technical decisions. Collaborate closely with Product, Design and domain experts to turn ambiguous problems into elegant, well-engineered solutions. Bring your own product…
