Software Engineering Intern / API Integrations

We are a regulated fintech from Hamburg building the compliant payment layer between AI agents and data providers. Our infrastructure enables agents to discover, pay, and consume data autonomously — using e-money tokens, the x402 protocol, and real-time euro settlement.

Backed by the City of Hamburg, MiCAR-compliant, PSD2-regulated. The role We're looking for a proactive developer-researcher in Berlin who sits at the intersection of code and market intelligence.

You won't just research, you'll build prototypes, test integrations, and shape how we position ourselves in a fast-moving market. This role is ideal for someone who likes digging into new protocols, testing APIs hands-on, and turning findings into actionable recommendations.

Tasks • Map the agentic payments landscape: who are the players, what protocols exist (x402, MCP, Skyfire, etc.), where are the gaps • Identify and evaluate potential data provider partners (weather, finance, geo, pricing APIs) for our pilot program • Research and categorize data providers across verticals — build a product matrix comparing pricing models, API quality, MCP readiness, and agent compatibility • Build small proof-of-concepts and test integrations with MCP servers and data provider endpoints • Analyze competitor products, pricing models, and regulatory positioning • Research how LLM platforms (Anthropic, OpenAI, etc.

) are integrating external data sources and payment layers • Synthesize findings into clear internal memos and pitch materials — no 50-page reports, short and actionable • Proactively flag opportunities, risks, and potential partners without waiting to be asked Requirements • Currently studying computer science, fintech, business informatics, or similar — or recently graduated • Can write code: comfortable with APIs, HTTP requests, basic scripting (Python, TypeScript, or similar) • Genuinely curious about AI agents, crypto payments, and fintech regulation — not just checking a box • Proactive by default: you see something interesting, you dig in and share it before anyone asks • Strong English communication skills, written and verbal • Based in Berlin or willing to be • Bonus: experience with blockchain/stablecoins, MCP, or fintech regulation Benefits • Direct access to the founding team — your work shapes product and strategy decisions • Real ownership: your research and prototypes go into production, not a drawer • A front-row seat to the intersection of AI, payments, and European regulation • Flexible hours (Werkstudent: 15-20h/week, Praktikum: full-time for 3-6 months) • Office in Berlin, remote flexibility Send a short email with your CV and a few sentences on why this excites you.
