AI-Native Product Engineer

About Gambooza Gambooza helps bars and restaurants run on their own data. We connect to a venue's point-of-sale (POS) system and, where installed, its cameras, and turn what happens behind the bar into answers a manager can act on: what was poured versus what was billed, how service is going, what needs attention today. Our newest product is the Manager Virtual: an AI agent that managers talk to from their phone, by text or voice note, and that answers with figures, reports and video from their own venue. Next on the roadmap: modules for supplier delivery notes, stock and more of the day-to-day of running a venue. We're an early-stage, venture-backed startup supported by Lanzadera, Patio, CIEC, C-Lab and Madrid Food Innovation Hub. The team is small, so what you ship reaches real customers within days. What matters most to us Skills can be learned. These three things are what we really hire for: 1. You act before you're asked. You spot what needs doing and get on with it: a bug nobody has logged, a process that could be faster, a customer question that hints at a missing feature. You don't wait for a ticket to move. 2. You enjoy solving problems with 360° thinking. A challenge excites you rather than worries you. You look at a problem from every side, not only the code but also the customer, the business and how it will work on site, and you look for the solution that works for all of them. 3. You roll up your sleeves. In a startup some work is brilliant and some is far less glamorous. Both have to get done. What counts here is the result, not the attempt. Why this role This is a junior role, but not a hand-holding one. You'll get a problem (say, "managers need to log supplier delivery notes from their phone") and own it end to end: understand the user, decide what to build, build it with AI agents, check it works and ship it. We'll give you context and feedback, not step-by-step instructions.

What you'll do
• Turn real problems from bar and restaurant managers into product: new app modules (delivery notes, stock and more), new skills for our Manager Virtual agent, new POS integrations.
• Build agentically: most of our code is written by AI coding agents driven by the team. Your job is to give them the right context, break the work down, review what they produce and make sure it actually works.
• Check your own work: tests, real data, trying it on a phone the way a manager would. "It compiles" isn't done; "the customer can use it" is.
• Talk to customers and the team, spot what's missing and propose it before anyone asks.
• Leave things clearly documented, so the next person (or agent) can pick them up.
• We don't hire for a framework. Our stack (TypeScript, React, Python, Firebase) matters far less than how you work: with AI agents, with judgment, and without needing someone looking over your shoulder. What we're looking for
• 0–2 years building software: a first job, internships, a bootcamp or personal/university projects all count. What matters is that you've shipped something real.
• You know how to code with AI agents and have your own way of working with them: how you give them context, plan the work, review what they produce and test it.
• Good engineering judgment, even as a junior: you can read code you didn't write, notice when something is off, and know that "it works on my machine" isn't the finish line.
• You understand people before code: you can talk to a bar manager, get what they actually need and turn it into something simple.
• You manage yourself: you organise your own work, ask when you're blocked instead of waiting, and finish what you start.
• A big plus: you've built an AI agent yourself, something that uses tools, works with real data and answers real users (like our Manager Virtual).
• Nice to have: some TypeScript or Python, Git, Firebase/GCP.
• Fluent Spanish: our customers are bars and restaurants in Spain.

What we offer
• Learn to build software the way it's going to be built: agent-first, in production, with real customers and direct feedback from the team.
• Visibility of how a startup is built, from tech to customers to fundraising.
• Hybrid setup in Madrid and flexible hours.
• Competitive salary based on experience.
• A small team where your work is visible and your opinion counts. Join us if… You move before you're asked, you enjoy cracking a problem from every angle, and you're happy to do whatever it takes to get a good result. If that's you, we'll give you more responsibility as fast as you can take it.

How to apply
Apply through LinkedIn with your CV. If you want to stand out, add a short note (optional) telling us:
• Something you've built: what it does, who it's for, and a link or demo if you can share it.
• How you built it with AI agents: which agents you use, how you give them context and plan the work, how you review and test what they produce, and one time an agent got it wrong and how you noticed.
• A problem you solved without anyone asking you to.
• Which area of software development you enjoy most and which you enjoy least, and why.
• Why Gambooza: what caught your attention, and one thing you'd build or improve for a bar or restaurant manager after reading this offer. Write it yourself. Use AI for whatever you like, but we want to hear how you think.
