About Mindsight Ventures

At Mindsight Ventures, we’re building next-generation AI-powered platforms that connect data, people, and intelligent systems in fields like health, finance, and automation.

We partner with startups, enterprises and venture builders to design intelligent systems — from AI agents and data platforms to full-stack products — helping companies move faster from idea to execution.

Our team works across multiple domains — product design, software development, AI research, and cloud infrastructure — always guided by the same principles: clarity, efficiency, and real-world impact.

We’re based in Barcelona, with a hybrid work model and an international team of engineers, designers, and entrepreneurs.

About the role

We’re looking for a talented AI Engineer to help us design, build, and deploy AI-driven systems and backend infrastructures for our internal platforms and client projects.

This role bridges software engineering, cloud DevOps, and machine learning deployment — ideal for someone who enjoys solving complex technical challenges and building scalable systems.

Your responsibilities

• Develop and maintain backend services (Node.js, TypeScript, or Python)
• Design APIs, data pipelines, and system architectures
• Implement and deploy AI/ML models (training, testing, inference, and MLOps)
• Work with cloud environments (Azure, AWS, or GCP) for deployment and scaling
• Explore modern AI infrastructure patterns (e.g., RAG, vector databases, model serving)
• Collaborate with the front-end and AI research teams

Requirements

• 2–4 years of experience in backend or AI development
• Strong programming skills in TypeScript and/or Python
• Experience with cloud infrastructure (Azure preferred) and CI/CD
• Knowledge of databases (SQL/NoSQL), APIs, and containers (Docker)
• Understanding of ML frameworks and deployment workflows
• Strong architectural thinking and curiosity for new technologies
