At Wiremind, the Data team is responsible for developing, monitoring, and evolving all ML-powered forecasting and optimization algorithms used in our Revenue Management systems. The team consists of Machine Learning Engineers, who develop and monitor ML models, and Data Engineers, who ensure smooth integration of these models into our software. Our algorithms are divided in 2 parts: ML models to forecast unconstrained demand, capacity and overbooking (e.g. boosted trees, deep learning), trained on historical data in the form of time-series; Constrained optimizations problems solved using linear programming techniques. CARGOSTACK is an end-to-end SaaS solution for airlines to manage their cargo business. It combines a Cargo Management System (CMS) with optimization modules leveraging AI models to provide forecast to support users when taking decisions such as setting the right level of capacity for sale (in kg and m3), the right price, the right overbooking level, or the best pallet build-up (think of a 3D-Tetris optimizer). As a Machine Learning Intern, with support from more senior ML Engineers, you will leverage state-of-the-art AI/ML methods and ironclad validation processes to deliver robust, interpretable prediction systems.
Job Responsibility:
Designing/training of new models (decision trees or neural network) to improve our current models in production
Tackling cargo demand specific challenges: imbalanced data, skewed data distributions, features engineering
Performing in-depth model evaluation to properly assess live model performances and identify data drift or areas for improvements
Taking part in the improvement of our training pipeline framework (tests, automation..)
Survey state of the art models / practices in our domain specific applications
Requirements:
Currently pursuing a Master’s Degree in data science, computer science or applied mathematics
Good understanding of fundamental machine learning concepts, including classification and regression tasks, as well as their underlying mathematical principles
Good understanding of basic evaluation metrics : accuracy, recall, precision, RMSE etc, as well as basic statistics
Hands-on experience with python language and standard data tools: Pandas, NumPy
Strong curiosity and desire to learn
Solid computer science background in Python
Good experience in model development (Kaggle, class or personal projects,..)
What we offer:
Attractive remuneration
Training on demand
Hybrid policy: a day of remote work per week and the possibility to work occasionally from abroad
Great company culture (monthly afterworks, regular meetings on technology and products, annual off-site seminars, team-building…)
Beautiful 800 m² offices in the heart of Paris (Bd Poissonnière)
Caring and stimulating team that encourages skills development through initiative and autonomy
Learning environment with concrete opportunities for evolution
