Job Description

At Wiremind, the Data Science team is responsible for the development, monitoring and evolution of all ML-powered forecasting and optimization algorithms in use in our Revenue Management systems. Our algorithms are divided in 2 parts: A modelling of the unconstrained demand using ML models (e.g.deep learning, boosted trees) trained on historical data in the form of time-series; Constrained optimizations problems solved using linear programming techniques. You will be joining a team shaped to have all profiles necessary to constitute an autonomous department (devops, software and data engineering, data science, AIML, operational research). There, under supervision of a Wiremind tutor and researchers from UBC, you will push the boundaries of state-of-the-art causal inference modeling for time series. As a research intern, you will have the opportunity to contribute to innovative projects at the intersection of deep learning and causal modeling.

Job Responsibility

  • Leveraging causal inference methods like Regression Discontinuity Design or Orthogonal Learning to analyze and model complex demand patterns using time series data
  • Developing state-of-the-art deep learning architectures to improve the accuracy of current best models while maintaining causality and elasticity
  • Exploring the impact of pricing sequences on demand by modeling consumer behavior from a series of price changes instead of single adjustments

Requirements

  • Strong computer science background in python, with a keen interest for code quality and best practices (unit testing, pep8, typing)
  • Knowledge about at least one major deep learning framework, e.g. tensorflow, pytorch
  • A pragmatic, prod-oriented approach to ML: frequent, incremental gains beat a grand quest for perfection

Nice to have

  • A first experience in a pricing-related domain
  • A wish to puruse a career in academia with a PHD following the internship

What we offer

  • 1 day of remote work per week
  • A great company culture (monthly afterworks, regular meetings on technology and products, annual off-site seminars, team-building…)
  • Beautiful 900 m² offices in the heart of Paris (Bd Poissonnière)
  • Attractive remuneration
  • A caring and stimulating team that encourages skills development through initiative and autonomy
  • A learning environment with opportunities for evolution
