Senior Product Manager (Echo) in City of Westminster

Mangopay is a wallet-based payment infrastructure built specifically for organisations with complex, multi-party fund flows. A pioneer in multi-party payments, our solution optimises fund flows on behalf of the organisations we work with using wallets as programmable, composable building blocks. Mangopay’s regulated platform collects payments, secures transactions and holds funds, splits money between the various parties in the funds flow, and ultimately manages the payout to service providers, sellers, and consumers. Platforms and fintechs using Mangopay regain control and transparency over multi-party payment flows, generate additional revenue, and improve operational efficiency.

At Mangopay, we’re building the modular payment infrastructure that powers the platform economy. Echo is a key part of that vision: a PSP-agnostic extension of the Mangopay wallet that enables marketplaces and platforms to keep their existing acquiring setup, often across multiple PSPs, while centralising downstream fund management, reconciliation and payouts within Mangopay. We are looking for a Senior Product Manager to join our Echo product team. This is a high-impact, technical individual contributor role for someone who is comfortable operating at the intersection of payments, APIs, reconciliation and operational tooling.

You’ll help shape and mature a product that solves real complexity for enterprise marketplaces and platforms: fragmented payment flows, multiple providers, operational overhead, and the need for clean, reliable downstream fund management. You won’t just define roadmap themes; you’ll work closely with Engineering, Operations, Compliance and commercial teams to turn product strategy into scalable product capabilities. That means helping Echo become easier to implement, easier to operate, and more valuable for customers running sophisticated payment setups.

What You’ll Do

• Technical Product Ownership: As Senior Product Manager, perform the Product Owner role within the Echo team. You’ll translate product direction into clear, developer-ready user stories, acceptance criteria and release plans.
• Bridge the Gap: Work closely with Product leadership and Engineering teams to transform discovery work and customer insight into seamless, scalable product capabilities for clients using complex payment and wallet setups.
• Discovery and Delivery: Lead discovery on high-value Echo problems, then own the delivery of that work into live features that create measurable customer value.
• Own the Core Echo Experience: Help shape the core product flows that sit at the heart of Echo, including intent declaration, settlement ingestion, reconciliation, split execution, and the handling of exceptions and downstream fund movements.
• Build for Operational Excellence: Echo is not only an API product; it is also an operational product. You’ll help define the visibility, tooling and workflows that allow both customers and internal teams to understand what is happening, resolve issues quickly, and operate confidently at scale.
• Support Complex Platform Models: Work on product capabilities that support real-world marketplace and platform complexity, including hybrid payment setups, 1P and 3P flows, and customers operating across multiple PSPs or acquiring partners.
• Architect the Connector Strategy: Collaborate with Engineering leadership on how Echo should interact with external PSPs and acquiring systems while keeping the Mangopay experience consistent, robust and easy to integrate.
• Standardise Global Logic: Ensure that core capabilities such as reconciliation logic, exception handling, reporting foundations, and fund distribution patterns are standardised wherever possible, so customers do not need to absorb unnecessary complexity.
• Optimize for Performance: You are data-native. You don’t just launch and leave; you define the metrics that matter and use them to improve adoption, reliability, operational efficiency and customer outcomes.
• Jira & Sprint Mastery: Maintain a high-velocity delivery pace. You’ll keep the backlog healthy, ensure the engineering squad is unblocked, and make pragmatic trade-offs between technical debt, rollout needs and longer-term product capability.
• Customer Mindset: You obsess over outcomes for customers. Everything you shape should make Echo easier to adopt, easier to operate, and better aligned with how marketplaces and platforms actually run payments.

What You Bring

• 5+ years of fintech / API product experience: You’ve spent significant time building API-first products in fintech or similarly complex B2B infrastructure environments, ideally in payments.
• Deep payments understanding: You are comfortable discussing payment flows end to end, including acquiring, refunds, disputes, settlement and reconciliation.
• Experience in complex acquiring environments: You’ve worked with some of the world’s largest acquirers, payment orchestration platforms, or multi-PSP setups, and understand the product and operational problems that arise in those environments, especially for marketplaces and platforms.
• A technical PO mindset: You are comfortable in detailed engineering conversations and can move fluently between architecture, product design and operational workflows.
• Marketplace / platform product sense: You understand the complexity of moving funds across multiple parties and designing products that work for both technical users and operational teams.
• Scrum fluency: You have a strong track record of working in fast-moving Agile environments and driving delivery through a clear, well-prioritised backlog.
• Data-native DNA: “The data shows” is part of how you work. SQL and Looker are strongly preferred, and experience with similar BI tools is valuable.
• Operational product thinking: You know that some of the hardest product challenges are not in the happy path. You think carefully about edge cases, exception handling, supportability and scale.
• Execution focus: You have a reputation for taking complex, ambiguous problems and getting them across the finish line.
• Strong stakeholder management: You can align Product, Engineering, Compliance, Operations and GTM stakeholders around clear decisions and realistic delivery plans.
