About Cala AI From the creators of Vilynx - a Barcelona AI startup acquired by Apple - comes Cala AI: a bold new venture redefining how information is verified and represented at massive scale. Based in Barcelona's vibrant tech hub near Passeig de Gràcia, Cala AI is building innovative AI systems focused on trust, accuracy, and impactful technology that challenges industry norms.
Recently, Cala AI was named by Creandum to their #EuroSeed50 list - highlighting the most promising early-stage startups in Europe - an honor that reflects the strong belief in our mission and team. We are a small, ambitious group dedicated to building real solutions with grit, heart, and a culture of authenticity.




We are now growing our engineering team with an experienced Data Engineer who enjoys working across boundaries - data, backend, infrastructure, and applied AI.
About the role We're looking for an experienced data engineer with depth.
You'll come from a Data Engineering background - big data pipelines, storage systems, processing frameworks - but what matters most is your motivation to build across layers and solve complex problems end-to-end. Data is your anchor, but this is a high-impact engineering position for someone who enjoys working with multiple parts of the system rather than in a narrow specialization.
You'll architect, build, and scale the data systems that power large-scale AI-driven information verification and representation, engaging with emerging information representation systems like embeddings, Knowledge Graphs, and search engines to help shape the future of AI-driven data.
What you'll do Design and maintain scalable, h
