February 17, 2021 Sr. Data Scientist

Who are we?

Do you want to build software that cracks cybercrimes and paralyzes Mr. Robot in his tracks? Do you dare to read the minds of hackers and predict the next nation-state cyberattack? If so, then you belong at Denexus!

DeNexus is what happens when machine learning meets threat hunting. We are a team of visionary engineers scrambling to defend the world using data science. Our mission is to model and stop industrial cyber catastrophes like nuclear explosions and electrical blackouts. If you catch yourself questioning the realstory behind Stuxnet or how many new exploit kits get sold each year in the underground cyber market, then join us in developing the world’s first statistical engine for measuring industrial cyber risk.

Attacks are fast evolving. Defense starts with a true understanding of the system at risk.

Duties and responsibilities

As a data scientist, you love creating statistical models and are passionate about making sure that your models accurately describe the real world by making sure that they preserve qualitative properties of the observed data. You aren’t scared to build a new model from scratch according to specifications provided by subject matter experts, find thrilling the challenge of facing completely new problems every day and having to find ways to tackle them, and love being in constant learning.

The ideal candidate has solid prior background in statistical modeling, having worked as a data scientist using techniques that create explainable models like Bayesian modeling instead of black box models like neural networks.


· Decide which models and statistical distributions more accurately describe frequency and impact of cyber attack events

· Create models that give the full probability distribution of outcome events, rather than just a point estimate of the most likely outcome

· Test said models, find corner cases for which they don’t work accurately and figure out ways to improve them

· Help an interdisciplinary team define the best way to build cyber attack chains from standalone alerts. For this task, use of more traditional black box machine learning techniques might also be useful


· 2+ years experience with statistical modeling

· Familiarity with Bayesian modelling is a must

· Fluency programming is a must (you will be mainly using Python)

· Experience with machine learning (Neural networks, boosted trees, SVMs) is a plus

· Experience with clustering machine learning techniques is a plus


· Remote working in Europe. Most of the team you will be working with is based in Madrid, Spain
