Senior Full Stack & Ai Developer

Gambooza is a purpose-driven startup on a mission to make the global food industry radically more efficient and sustainable. Our AI-powered solution helps food businesses measure operations, detect inefficiencies, and reduce food waste.

We combine artificial intelligence with deep food industry expertise to empower companies with actionable data—whether it’s optimizing prep in kitchens, streamlining shop operations, or tracking consumer waste.

Actively exploring partnerships with some of the top universities in Spainand and backed by top European accelerators like Lanzadera, Patio, CIEC (Centro de Innovación en Economía Circular), C-Lab and Madrid Food Innovation Hub, we’re building tech that matters—and we’re just getting started.

Why This Role is Unique

This is not a typical dev job. You’ll work closely with the C-Level team, directly influencing both technical and business decisions. You’ll have a seat at the table where strategic choices are made and the opportunity to shape a product with real-world impact.

We’re looking for someone who wants to leave a mark not only on the technology but on the business as a whole —helping us build a scalable product, define new opportunities, and solve meaningful challenges in the food industry.

We need a builder who can work autonomously with minimal guidance , driving projects from concept to production.
