About Gambooza

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.

What You’ll Do

• Collaborate directly with the C-Level team to define and execute our technical and business roadmap.
• Build production-grade features for:
• A React / Next.js WebApp
• A Kotlin or React Native Android app
• An admin dashboard (TypeScript, Firebase, Node.js)
• Integrate AI and machine learning components, including both computer vision models and Large Language Models (LLMs), into production systems (Python, TensorFlow, PyTorch, or similar).
• Architect scalable solutions for data handling and device communication across IoT and cloud services.
• Design and develop RESTful APIs and/or GraphQL services.
• Work with both relational and NoSQL databases.
• Set up and maintain CI/CD pipelines and manage cloud deployments.
• Implement automated testing (unit, integration, and E2E) to ensure code quality and maintainability.
• Contribute to both product and business decisions, helping identify new opportunities and improvements.
• Help mentor junior engineers as the team grows.

What We’re Looking For

• Solid experience as a Full-Stack Developer, ideally combining the agility and ownership of a startup/scale-up environment with the structure and rigor of large corporate projects.
• Strong skills in:
• JavaScript/TypeScript
• Python
• One or more frameworks like React, Node.js, Kotlin, or React Native
• Proven ability to ship features end-to-end and work independently.
• Hands-on experience integrating and deploying Large Language Models (LLMs) into production systems.
• Experience designing RESTful APIs and/or GraphQL services.
• Good understanding of relational and NoSQL databases.
• Familiarity with CI/CD pipelines and deploying apps to cloud platforms (e.g., AWS, GCP, Azure, Vercel, etc.).
• Knowledge of automated testing practices and tools (unit, integration, E2E).
• Bonus: Docker, Kubernetes, or cloud infrastructure experience.
• Strong problem-solving mindset, proactive attitude, and excellent communication skills.
• Comfortable making decisions and moving forward with minimal guidance in a fast-paced, evolving environment.

What We Offer

• The chance to work on cutting-edge tech in the food industry.
• Direct influence over product, technical direction, and business strategy.
• Flexible schedule and remote-friendly culture.
• Competitive salary plus equity options in the company.
• A mission-driven team where your voice matters, and your work has visible impact.
• A unique opportunity to join a venture-backed startup early and help define its success.

Join Us If…

You’re excited to build real-world solutions that combine software, hardware, and AI—including Large Language Models—and you want to shape not only the technology but the future of the business itself, driving innovation and sustainability alongside a passionate team.
