THE SPIRIT OF VIVA LA DIFFERENCE
Viva La Difference is deeply rooted in everything we do. It has always been in our DNA. From the birth of Publicis, 94 years ago, when Marcel Bleustein-Blanchet, our founder, invented French advertising. Viva La Difference expresses how we value and respect each individual and recognize what makes us distinctive. This is the charge that inspires our teams to celebrate the differences in identity, background, culture, and experience of all of us. It is how we behave with each other and our clients, and it is deeply rooted throughout our work, to elevate and bring to life our differences throughout the platform world..
Overview
We are seeking a Technical Lead Data Scientist to lead the design and delivery of advanced analytics and machine learning solutions that power our data-driven products and decision-making processes.

- Design, validate, and deploy machine learning models and advanced analytics solutions that support production forecasting, recommendation, and automation
- Guide the technical direction for statistical modeling, NLP, computer vision, and LLM-based solutions where applicable
- Partner with engineering teams to ensure data science solutions are scalable, production-grade, and cost-efficient across cloud platforms
- Establish and enforce standards for model reproducibility, monitoring, documentation, and governance
- Act as a thought leader within the organization, staying current with emerging AI/ML technologies and evaluating their strategic value
Qualifications
Experience
- Extensive experience in data science, machine learning, or advanced analytics, ideally in a technical leadership role
- Proven expertise in Python and ML frameworks (e.g., PyTorch, TensorFlow, Scikit-learn) and experience across NLP, computer vision, and LLMs

- Proficiency in SQL and working with large-scale, cloud-based datasets
- Deep understanding of MLOps principles and integrating ML solutions into production environments
- Demonstrated ability to translate ambiguous business problems into scalable, production-ready data science solutions
- Hands-on experience with cloud platforms (AWS, GCP, Azure) and tools such as Databricks, Snowflake, and BigQuery
- Exceptional communication and stakeholder management skills, with the ability to influence decision-making across technical and non-technical teams
Desirable skills
- Familiarity with real-time model serving, monitoring, and performance optimization
- Experience with LLM frameworks (e.g., LangChain, Hugging Face, Chroma, Mistral) and generative AI applications
