this is first-principles AI research, and we intend to keep it that way.To thrive in this role, a strong theoretical background in mathematics, AI, and machine learning is indispensable.You will be working at the intersection of computational theory, cognitive modeling, and algorithmic design, where rigorous mathematical intuition is the foundation of every contribution.If you are driven by deep curiosity, unafraid of uncharted territory, and eager to work on AI that defies the current mainstream, we want to hear from you.You will report to the CTO of the company.Experience & BackgroundEngineering studies, or equivalent, in which the candidate has acquired a solid foundation in understanding and the functioning of the main ML and AI technologies.4+ years experience in the development of ML/AI solutions.2+ years experience in data processing and analysisIdeally experience in functional languages (Julia, Scala, Haskell,...)SkillsStrong communication and presentation skills, capable of translating technical concepts into clear value propositions.Result-oriented, proactive, and comfortable working autonomously in a dynamic environment.Fluent in English.Nice-to-Have QualificationsPhD in AI, Data Science, Information Theory, or related fields.Academic publications in relevant fields.What You'll DoLead the design and optimization of our Fractal AI algorithm for general intelligence.Be part of the team that applies our Synthetic Cognition technology to laboratory or business use cases.Participate in the maturation of Synthetic Cognition as a product for data analysis.Why Join Us?Impact: Be at the spearhead of AI innovation, applying valid technology to real clinical challenges.Growth: Learn from a multidisciplinary team combining AI, data science, biology, and innovation.Learning: Work in a multidisciplinary team combining AI, data science, biology, and innovation.Culture: Flexible, employee-centric, and intellectually stimulating environment with significant growth opportunities.Ownership: Be the co-author of patents or papers in top-tier academic publications. ## Related Videos - [Getting Started with Machine Learning](https://www.wearedevelopers.com/videos/260-getting-started-with-machine-learning) - [Implementing continuous delivery in a data processing pipeline](https://www.wearedevelopers.com/videos/73-implementing-continuous-delivery-in-a-data-processing-pipeline) - [How Regex Works: The Secret Sauce Behind Pattern Matching](https://www.wearedevelopers.com/videos/1212-how-regex-works-the-secret-sauce-behind-pattern-matching) - [Every CEO needs a digital twin to understand the scope of generative AI](https://www.wearedevelopers.com/videos/1006-every-ceo-needs-a-digital-twin-to-understand-the-scope-of-generative-ai) - [Geometric deep learning for drug discovery](https://www.wearedevelopers.com/videos/264-geometric-deep-learning-for-drug-discovery) - [Agentic employees in world's most downloaded FinTech app](https://www.wearedevelopers.com/videos/100123-agentic-employees-in-world-s-most-downloaded-fintech-app) ## Related Articles - [How to Become an AI Engineer](https://www.wearedevelopers.com/magazine/331-how-to-become-an-ai-engineer) - [What Industries Outside of AI Are Hiring The Most AI Experts?](https://www.wearedevelopers.com/magazine/98-what-industries-outside-of-ai-are-hiring-the-most-ai-experts) - [Navigating the AI Shift](https://www.wearedevelopers.com/magazine/629-navigating-the-ai-shift) - [Coffee with Developers - Maria Apazoglou - Making AI understandable for all in production](https://www.wearedevelopers.com/magazine/475-coffee-with-developers-maria-apazoglou-making-ai-understandable-for-all-in-production) - [MLOps And AI Driven Development](https://www.wearedevelopers.com/magazine/82-mlops-and-ai-driven-development) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline)
