About the Position

Software Engineer, Full-Stack with AI

Engineering | Barcelona | Remote | Full-time

Salary: €22,000 – €45,000 per year

Industrial companies are asked for more and more environmental data (by customers, tenders, auditors and banks), and every request asks the same thing in a different format. Mappa is the AI suite that connects the data a company already has, organises it and calculates its footprint on a certified methodology: report once, answer everything.

On top of that core, each customer uses AI to create their own tools without coding, such as a supplier portal or the footprint of every quote. Over the next 12 months you will build those agents and tools, and connect Mappa to each company's ERP and documents so every piece of data is entered only once. You will also work on the auditor agent, which will review the emissions inventory before the external auditor does.

We are hiring two people, from junior to experienced, starting immediately. Spanish is required.

Process: we reply to every application, and after each stage you hear from us within a week.

1. A 20 minute call with Víctor, our CPTO.
2. A modular technical challenge: you pick a piece of the product and how far you take it, and show it in a demo.
3. An interview with Jordi, our CEO, about motivation and fit.
4. A conversation with the team. We use AI to organise applications; every decision is made by a person.

Responsibilities

• Within 6 months, a tool or agent you built is in production with customers.
• Within 6 months, you have connected a new customer's data end to end.
• Within 12 months, the auditor agent works with real customers.
• Within 12 months, you own a part of the product and decide what gets built.

Requirements

• You have shipped something to production with real users, at work or in your own project.
• You code with AI every day and know when not to trust what it generates.
• You care about the customer's problem as much as the code.
• You ask for help when you are stuck and say "I don't know" when you don't.
• You speak Spanish and read technical English.
• You want industry to get its environmental data in order.

Nice to Have

• Our stack today: TypeScript, React and Next.js, PostgreSQL and Claude Code; we don't expect you to master all of it.
• A small solution you understand deeply is worth more than a big one you can't explain.

We Offer

• €22,000 to €45,000 gross per year depending on experience, full time.
• Barcelona or remote, starting immediately.
• People first: every hire has a name and a face.
• AI is open and paid for by the company: use it as much as you like, as long as you understand your result.
• Close wherever you are: we have an office in Barcelona and like to share it; if you live elsewhere, you work remotely and we meet when it makes sense. Flexible hours.
• A small team that decides fast, and the people in the thick of it grow with the company.
• What you build will be used by customers within weeks.
