Senior Product Manager (API)

We believe everyone deserves seamless access to Web3 and traditional financial services, so we're building the platform that makes it real: one that simplifies crypto and integrates it into the broader financial ecosystem.Since launching in 2018, we've grown into a recognized force in the industry, named one of Europe's Fastest-Growing Startups 2025 by Sifted and awarded Best Crypto On-Ramp & Payments Solution 2025 by Cryptonomist. We've partnered with leading brands including Visa, Mastercard, MetaMask, Trust Wallet, Ledger, and Jupiter, powering over 200 products and collaborating directly with major ecosystems like Solana, Consensys, and BNB Chain.Why Mercuryo?Industry ImpactJoin us in helping world-class Web3 projects onboard millions of new users into the next generation of finance.Innovative EnvironmentCollaborate with more than 300 talented professionals from diverse backgrounds - including banking, SaaS, and Web3 — all united in delivering outstanding user experiences.Growth and LearningOur expanding network of 200+ B2B partnerships and a user base of over 7 million means there’s always room to grow your skills, tackle new challenges, and push boundaries.Flexible CultureWe’re remote-first, celebrating diversity across 30 countries. At Mercuryo, you’ll be empowered to take ownership of your work, spark creativity, and shape how we move forward together.Our Product Culture:Our product teams are empowered to tackle challenging problems - both customer-related and business-oriented - in ways that delight our customers and benefit our business. We equip these teams with the necessary skills to devise solutions that are valuable, viable, usable, and feasible. While the product designer ensures usability and engineers ensure feasibility, the product manager is accountable for value and viability. This requires understanding business constraints across compliance, legal, sales, finance, and privacy, as well as maintaining a deep understanding of users, partners, market dynamics, and competitive disadvantages. At Mercuryo, a product lead acts as a mini‑CEO. The day‑to‑day focus is setting a clear product strategy and direction, and continuously aligning the team around it. Product managers are expected to be strong communicators and rational decision‑makers, explicitly assessing value, impact, and trade‑offs when prioritising initiatives across teams. Our delivery model is built around speed of learning. We ship quickly to validate ideas in the real world, which makes the team deliberately flaw‑tolerant. Speed does not mean cutting corners. Fast delivery demands clarity. Before anything reaches development, ideas must be well thought through from both business and technical perspectives, with particular attention to reliability, compliance, and security.About the Role:We are looking for a Senior Product Manager (API) to own and shape the developer experience around Mercuryo’s full on-ramp infrastructure.This role sits at the intersection of product, developer platform, payments, and infrastructure.
