MONEI is revolutionizing omnichannel payments for top brands across Southern Europe. Our award-winning serverless architecture even earned recognition as the AWS Startup Architecture of the Year (Iberia region). With rapid global expansion underway, we're building the future of payment processing-and we want you on our team. The Role

This is a hybrid role: you'll do both Technical Merchant Support and Developer Advocacy. One day you'll be debugging a failed payment for a merchant; the next, you'll be writing the doc that prevents that same ticket from ever happening again. We're not looking for someone who picks a side-we're looking for someone who thrives at the intersection.

You'll be the bridge between our engineering team and the people who use MONEI: merchants, developers, partners, and internal teams. You'll investigate real issues, ship small fixes, keep our docs sharp, write tutorials, and engage with the developer community-all in the same role.

You'll work directly with one of our senior engineers, who'll invest in your growth from day one.

We're open to multiple formats:

• Full-time for experienced candidates with a mix of technical support and developer-facing experience.
• Part-time or paid internship (targeted at UPC and similar tech students, ~20h/week, hybrid from our Barcelona office) with a clear path to a full-time role after a successful trial.

• Own Developer & Merchant Documentation: Keep our public and internal docs accurate, clear, and AI-friendly based on what you learn from real tickets.
• Write Guides & Tutorials: Publish content that helps developers and merchants integrate MONEI faster.
• Improve APIs, Plugins & Integrations: Surface real customer feedback to engineering to refine API and plugin design.
• Improve Internal Tooling & Runbooks: Spot recurring issues, write/update runbooks, and propose automation to scale support.
• Engage the Developer Community: Help maintain our Twitter/X presence and developer-facing channels.
• Ship Fast with AI: Leverage Cursor, Claude Code, and Codex to move quickly without sacrificing quality.

• Able to read and write code, for experienced candidates.
• Basic understanding of JavaScript/TypeScript for debugging.
• Knowledge of REST APIs and HTTP debugging required.
• Strong technical writing skills to create documentation.
• Basic SQL and query skills to pick up new languages.
