🧠About Zinco
At Zinco, we’re building the back-office of the future for millions of small businesses: accounting, taxes, payroll, financing — all AI-Powered by cutting-edge technology and a team of advisors who truly understand what matters to clients.
Technology powers everything. But real impact comes from people.
🎯 Your mission
As a Full Stack Engineer, your mission is to build the interfaces, systems, and tools that drive Zinco’s internal platform and client-facing experiences.
You’ll work across front-end and back-end to create fast, elegant, and highly usable dashboards, data tools, and automations. You’ll help bring clarity and control to complex financial, tax, and payroll workflows — with precision and speed.
This role is perfect for someone who codes fast, ships often, and cares deeply about both technical excellence and product usability.
You’ll play a key role in defining our tech foundations and helping shape the future team. This is a great opportunity to have an outsized impact from day one.
🚀 What you’ll do
- Develop and maintain back-end systems in Python, using FastAPI and Pydantic.
- Design and automate workflows that process documents, handle emails, and interact with APIs — using tools like n8n, Langchain, MCP, and OCR.
- Contributing to the deployment and monitoring of services, we currently use Railway for deployment.
- Ensure systems are secure, scalable, and resilient.
- Write clean, maintainable code — fast — and take ownership from idea to release.
- Design and implement dashboards, chat experiences and tools used by our teams and clients.
- Collaboration on ML pipelines or intelligent systems — experience with ML and MLOps is a plus.

🧬 What we’re looking for
- Based in Madrid - remote work is fine, but we love our office vibes!
- Experience with Python (FastAPI, Pydantic, Pandas) and JavaScript (ReactJS or similar frameworks).
- Experience with deployment pipelines and infrastructure.
- Passionate about experimenting with AI-powered developer tools like Cursor, Windsurf, or similar to accelerate coding and problem-solving.
- Hands-on experience with tools like MCP, Langchain, CrewAI, n8n, or similar agent/workflow frameworks.
- Deep understanding of data security and privacy, especially when dealing with sensitive client information.
- Pragmatic and fast: you move with urgency, write clean code, and prioritize impact.
🌱 How we work
- Flexibility & hybrid work: we believe in ownership and responsibility over schedules. We trust people to manage their time and deliver results. We also value working side by side: we enjoy being together in the office around three days per week to collaborate, think, and build as a team.
- Tools & setup: AI-first tools and workflows, latest-generation hardware, and everything you need to work faster and better. If a tool helps you move quicker or think clearer, we want you to have it.
- Growth & development: You’ll have a dedicated training budget to invest in whatever helps you grow. We’re clear about where we are and where we’re going as a company, and you’ll have two performance reviews per year to support your development and career progression.
- Compensation: We believe in a meritocratic culture: your impact and results directly shape your growth and progression. We also offer flexible compensation (transport, restaurants, and other benefits) to make your day-to-day easier.
- Founder mindset & referrals: We like to grow with people who think like builders. That’s why we have a referral program — whether you bring great clients or future teammates.
