Marzieh Fadaee

Head of Research

During her work as NLP Research Engineer at Zeta Alpha, and with her PhD in Computer Science at the University of Amsterdam on meaning representation in machine translation, Marzieh heads our R&D efforts. Her interests lie in getting insights from data and understanding natural language. When not training understanding models, she’s training her own brain to learn a new language.

Mathias Parisot

Research Engineer

Mathias did his Master's thesis internship at Zeta Alpha and decided to stay on as a research engineer. No problem is too difficult for him, and he simply enjoys training very large models.

In his spare time he compensates for that by running very large distances.

Fernando Rejon Barrera

Head of Engineering

Fernando spent some time in academia while completing his PhD in theoretical physics, and afterwards  made a switch to industry in order to follow his lifelong passion for technology. He now focuses on software architecture of distributed systems, data engineering, MLOps, and cloud infrastructure.

Sergi Castella Sapé

AI Analyst

With a BSc in Physics and a Master's in AI, Sergi keeps the pulse for you on all new trends in AI.  He is a prolific blogger, the voice of Zeta Alpha on social media, and eager to read and explain as many cool AI papers as he can. A native of Barcelona, he is the most musical of the bunch, and has long good conversations with friends as a hobby.

Eduardo Ochoa

Senior Data Engineer

Eduardo is a former physics researcher turned Data Scientist and Data Engineer. He loves complex systems, but maybe even more to make complex things simple. Somehow more attached to Haarlem than to Amsterdam, he has also been bitten recently by the Zeta Alpha running craze, and has successfully completed the Dam tot Dam loop. Sometime he looks sentimental when Mexican food is discussed.



We are looking to grow the team with talented and fun NLP researchers, data and software engineers (both front end and back end), as well as entrepreneurial sales and marketing leads. If you are interested in joining our ambitious mission, please send your CV.
