Since 2014, Wiremind has positioned itself as a technical company transforming the world of transport and events with a 360° approach combining UX, software, and AI.
Our expertise lies primarily in optimizing and marketing our clients' capacity. We work on various projects such as ticket forecasting and pricing, 3D optimization of air freight or scraping competitor prices. Our applications are the preferred tool of companies such as SNCF, United Airlines, Qatar Airways or even PSG to visualize, analyze and optimize their capacity.
Dynamic and ambitious, we strive to maintain our technical DNA which is the engine of our success. The company, profitable and self-financed since its creation 10 years ago, is mainly composed of engineers and experts and currently supports the growth of our business model based on "software-as-a-service" solutions.
Your missions
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 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
The team is shaped to have all profiles necessary to constitute an autonomous department (DevOps, software and data engineering, data science, AIML, operational research) and works on a modern technical stack composed of argo-workflow (pipelines orchestrator), MLFlow (models \& experiments tracking) and in-house python packages.
Recently, we have begun exploring new ways of solving our revenue optimization problems using Reinforcement Learning techniques instead of linear programming.
As an Optimization Intern, you will take a part in this research effort by:
Exchanging on a daily basis with the data, ML and product teams to perfect your business comprehension
Proposing new ideas to solve revenue optimization problems
Implementing, testing and evaluating these ideas in a controlled environment
Technical stack:Backend: Python 3.11+
Orchestration: argo-workflows over an auto-scaled Kubernetes cluster
Datastores: Druid, ClickHouse, postgresql
Common ML libraries/tools: pytorch, scikit-learn, pandas, numpy
Reinforcement Learning: Gymnasium, stable-baselines3
Model versioning and registry tool: MLFlow
Gitlab / Kubernetes for CI/CD
Prometheus/Grafana and Kibana for operations \& monitoring
