Senior Product Manager (API)

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.
