Senior Product Manager (API)

Job description

Hi! We're Mercuryo , and we’re on a mission to redefine finance by blending the best of traditional banking with the power of decentralized finance (DeFi). 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 Impact Join us in helping world-class Web3 projects onboard millions of new users into the next generation of finance. Innovative Environment Collaborate with more than 300 talented professionals from diverse backgrounds - including banking, SaaS, and Web3 — all united in delivering outstanding user experiences. AI-First Culture We actively integrate AI across the company, from operations and analytics to marketing and product workflows. It helps teams move faster, improve productivity, and focus on high-impact work - while maintaining human oversight and accountability at every step. We see AI as a core part of how our teams innovate, collaborate, and scale. Growth and Learning Our 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 Culture We're remote-first, celebrating diversity across 30 countries. In 2026, Mercuryo was recognized as a Great Place to Work across five countries based entirely on anonymous employee feedback. The recognition reflects a culture of trust and collaboration. 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. You will define developer-facing API products and create seamless integration experiences for partners building on top of Mercuryo. You’ll work closely with engineering, design, integrations, commercial, and support teams to make our APIs intuitive, scalable, and easy to integrate - whether for enterprise clients, wallets, exchanges, or AI-powered developer workflows. This role is highly cross-functional and requires both strong product thinking and deep comfort working with technical products, APIs, SDKs, and developer documentation. Your Role: Own the strategy and roadmap for Mercuryo’s developer-facing API products and on-ramp platform. Define developer-friendly API experiences and specifications; ensure clear, AI-ready integration documentation. Improve developer onboarding and integration journeys to reduce time‑to‑first‑success. Partner with clients to surface integration pain points and continuously improve DX (developer experience). Drive tooling and quality across APIs, SDKs, documentation structure, error handling, and sandbox/testing flows. Prioritise by balancing technical feasibility, business value, compliance, and usability trade‑offs. Define and track success metrics: API adoption, activation, integration speed, and developer satisfaction. What We’re Looking For 5+ years of Product Management experience in fintech, infrastructure, developer platforms, API products, or technical SaaS products. Strong experience developing APIs as a product, not only integrating APIs. Experience designing developer-facing products, integration flows, or API documentation. Strong understanding of developer experience principles and API usability. Comfortable working closely with engineers and discussing technical architecture and API behavior. Ability to translate complex technical/payment flows into clear product requirements and developer documentation. Strong communication and stakeholder management skills. Analytical and structured problem-solving mindset. Experience in payments, crypto, fintech, or API-first businesses is a strong plus. Familiarity with OpenAPI/Swagger, Postman, SDKs, API testing tools, or AI-assisted developer tooling is a plus. What We Offer: Competitive market rate salary and performance-based incentives. 22 days annual leave with an additional 6 company days, plus bank holidays. Comprehensive health insurance plans. Maternity & Paternity leave support. Extensive benefits program. Flexible work schedule and remote work options. Modern offices and co-working spaces across 6 countries. Working equipment. Professional development and training opportunities. Opportunity to shape the initiatives you’re working on. Diverse and friendly team. We are open-minded to new ideas. Join Us!
