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.\nWe 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.\nOur 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.\nLearn more about why we do what we do here.\nThe role: Senior Product Engineer\nWe’re looking for a Senior Product Engineer to help redefine how institutions manage cash.\nYou’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.\nYou 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.\nYou’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.\nAI 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.\nRequirements\nWhat you’ll do: Responsibilities\nBuild and ship high-quality features across our React, TypeScript and Python stack, taking ownership from discovery through to production and continuous improvement.\n\nHelp reimagine how modern institutional treasury works by replacing manual processes and legacy systems with intuitive software.\n\nWork directly with customers to understand their workflows, pain points and goals, using those insights to shape product and technical decisions.\n\nCollaborate closely with Product, Design and domain experts to turn ambiguous problems into elegant, well-engineered solutions.\n\nBring your own product judgement. Prototype ideas, challenge assumptions, identify awkward user experiences and proactively propose simpler, better solutions.\n\nUse AI as a core part of your engineering workflow, orchestrating coding agents and modern AI tools to solve problems faster, automate repetitive work and unlock entirely new ways of building software.\n\nDeliver quickly through small, iterative releases, using customer feedback and production data to continuously improve what you’ve built.\n\nContinuously improve our products, engineering practices and internal tooling by identifying opportunities to simplify, automate and increase engineering leverage.\n\nCollaborate in a low-ego, high-trust team where curiosity, ownership and continuous learning are expected.\n\nWhat we’re looking for: Requirements\nStrong professional experience with Python, React and TypeScript.\n\nA track record of designing, building and shipping substantial customer-facing products across frontend, backend and data layers.\n\nStrong web and server-side engineering fundamentals, including component design, state management, APIs, relational databases, authentication and permissions.\n\nThe ability to quickly understand unfamiliar systems and confidently trace behaviour across application, service and database boundaries.\n\nExceptional customer empathy. You naturally put yourself in the customer’s shoes, seek to understand their workflows, goals and pain points, and use those insights to build products that genuinely solve customer problems.\n\nStrong product judgement. You enjoy taking ambiguous problems, identifying the underlying customer need, exploring different approaches and making thoughtful trade-offs between speed, simplicity and long-term maintainability.\n\nYou treat AI as a force multiplier, not a replacement for engineering judgement. You know when to trust AI, when to challenge it and when to replace its output entirely.\n\nStrong test-first mindset with a commitment to developer-led QA - you’ll take end-to-end ownership of your code's quality, test coverage, and reliability without relying on a separate QA team.\n\nCuriosity and a desire to continuously learn. Technology is changing rapidly and you’re excited to explore new tools, techniques and ways of working.\n\nClear written and verbal communication skills, with a collaborative, low-ego approach to feedback, design discussions and code review.\n\nWhat we offer: Benefits\nCompetitive salary, depending on experience\n\nEquity and bonus scheme\n\nUnlimited Paid Leave\n\nHybrid office-working model - we're in a great location near Green Park station in London\n\nEnhanced Parental Leave and Pay\n\nWorkplace Pension\n\nComplete Bupa HealthCare Cover\n\nLife Insurance\n\nIncome Protection Insurance\n\nAccess to Yulife (Employee Assistance Programme)\n\nRemote Office set-up budget\n\nCycle to Work Scheme\n\nA fun and dynamic working environment with regular team-building activities and events","description_format":"text","description_chars":5888,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Continuous learning","Equity","Life insurance","Parental leave"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Asset Management & Funds","Financial Software & Embedded Finance"],"lifecycle":[{"event":"open","at":"2026-09-11T15:41:44Z"}],"visa":[],"liveness":{"score":11,"band":"cold","label":"Long shot","p_open":1,"p_active":0.406,"p_room":0.28,"age_days":92,"expected_fill_days":36,"reasons":["conf:5","win:tail","crowd:"],"computed_at":"2026-11-04T06:34:25Z"},"pay":null,"html_url":"https://alion.io/job/treasuryspring-senior-product-engineer","json_url":"https://alion.io/job/treasuryspring-senior-product-engineer.json","meta":{"generated_at":"2026-11-04T11:08:05Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":16519,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-05T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":688939},"rest":"https://alion.io/mcp/rest/get_company?id=688939"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Ftreasuryspring-senior-product-engineer"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Ftreasuryspring-senior-product-engineer"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Ftreasuryspring-senior-product-engineer"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/treasuryspring-senior-product-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Ftreasuryspring-senior-product-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":750865}},{"tool":"search_jobs","arguments":{"company":"treasuryspring.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":750865},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
