The Role: Senior Product Manager, API & AI Platform

We're looking for a technically sharp, strategically minded Senior Product Manager, API & AI Platform to own Cryptio's API and AI Platform. This is a foundational role, responsible for the platform that underpins everything we build. This platform serves enterprise clients integrating our services, internal teams building on our infrastructure, and increasingly, AI systems consuming our endpoints programmatically. If you care deeply about developer experience, API design, and the emerging intersection of agentic AI and enterprise software, this role was built for you.

What You'll Do

This isn't just managing a backlog of endpoints; it's about owning a strategic platform layer that enables the entire business to scale.

• Define and drive the API roadmap, balancing the needs of enterprise clients, internal FDE teams, and AI/agentic consumers.
• Lead discovery with enterprise engineering teams to understand real integration patterns and translate them into coherent API design.
• Establish API design principles, versioning strategy, and deprecation policies that give clients and internal teams confidence to build.
• Design APIs with AI consumption in mind: structured responses, semantic clarity, LLM function-calling compatibility, and agentic workflow support.
• Own the end-to-end developer experience: authentication, documentation, SDKs, sandbox environments, error messaging, and time-to-first-call.
• Act as the central coordination point across Engineering, Enterprise Solutions, AI/ML, Sales, and Customer Success.
• Define and monitor platform KPIs: uptime, latency, error rates, adoption, and developer integration speed.
• Support client onboarding, bespoke integrations, and API-based deal enablement alongside Sales and Enterprise Solutions.

Tools You'll Use

• OpenAPI
• REST
• GraphQL
• Linear
• Notion
• Slack
• And whatever it takes to ship a world-class developer platform.

We're Looking For Someone Who

• Has deep technical fluency in API design, versioning, and enterprise integration patterns.
• Has experience building or owning developer-facing platforms and can speak credibly to engineering teams.
• Understands how LLMs and agentic systems interact with APIs and can design for that consumption model.
• Communicates clearly across technical and non-technical audiences, and thrives in cross-functional coordination roles.
• Brings strong product instincts: can synthesise competing stakeholder requirements into a clear, prioritised strategy.
• Is comfortable operating with autonomy and taking full ownership of a complex, horizontal platform.
• Bonus: experience in crypto, fintech, compliance, or data infrastructure.

Why You'll Love This Role

• Own a foundational platform that powers everything Cryptio builds; this is high-leverage, high-visibility work.
• Work at the frontier of AI-native product development, shaping how agentic systems interact with enterprise financial infrastructure.
• Collaborate with top-tier enterprise clients including exchanges, stablecoin issuers, custodians, and DeFi protocols.
• Partner closely with Engineering, AI/ML, and Enterprise Solutions teams on genuinely hard, interesting problems.
• Join a fast-moving company where your API strategy decisions will have direct commercial impact.
• Enjoy 100% remote work with occasional travel to our Paris or London hubs.
