Job Specifications
Since 2014, Wiremind has positioned itself as a tech company transforming the world of transport and events with a 360° approach combining UX, software, and AI.
Our expertise lies primarily in optimizing and distributing 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
Responsibilities
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, you will leverage state-of-the-art AI/ML methods and ironclad validation processes to deliver robust, interpretable prediction systems.
As a ML Engineer, with support from a Lead Data Scientist, you will take part in the development and improvement of new features and algorithms for our SaaS applications, using a mixture of proven traditional model-based methods as well as recent breakthroughs in Deep Learning for regression problems.
In practice, even though there is no typical day, you can expect to:
Develop, maintain, and propose improvements for our training framework via Argo + MLFlow
Deploy and monitor of models in production
Oversee implementations of new clients from the data analysis phase, modeling, deployment, and hyper-supervision of the first optimization runs in production
Develop analytics and AB testing tools to help us continuously improving our models
Technical Stack
Backend: Python 3.11+ with SQLAlchemy
Orchestration: Argo workflows over an auto-scaled Kubernetes cluster
Datastores: Druid and postgresql
Common ML libraries/tools: TensorFlow/Keras, LightGBM, XGBooost, Pandas, Dask, Dash, Jupyter notebooks
Model versioning and registry tool: Mlflow
Gitlab / Kubernetes for CI/CD
Prometheus/Grafana and Kibana for operations
Your profile
You have at least 3 to 5 years of experience working in Data Science, Applied Mathematics, Computer Science or similar field
You have worked on at least one deep learning framework such as tensorflow or pytorch
You have a pragmatic approach to ML where testing and frequent deliveries of small incremental gains supported by validation / alerting processes to avoid regression is preferred to a long tunneled research process
You're passionate about addressing business challenges through innovative technological solutions
You are committed to maintaining high-quality standards in all aspects of your work
Experience modelling time series and/or price elasticity is a plus
You are fluent in both french and english.
