THE WORK:

• Build and maintain data pipelines for ingestion, validation, transformation, and delivery of structured and unstructured data.
• Industrialize machine learning workloads by packaging models, automating deployments, and ensuring reproducible environments.
• Implement MLOps practices, including experiment tracking, model versioning, model registries, automated testing, approval workflows, and rollback strategies.
• Develop and operate APIs and batch services exposing data products and machine learning capabilities.
• Build and maintain CI/CD pipelines for data and ML solutions.
• Deploy containerized workloads using Docker, Kubernetes, and managed cloud services.
• Implement observability through monitoring, logging, metrics, data quality checks, drift detection, and alerting.
• Collaborate with data scientists and business stakeholders to deliver production-ready solutions.
• Contribute to infrastructure automation using Infrastructure as Code tools such as Terraform and Ansible.
• Produce technical documentation and contribute to knowledge sharing across engineering teams.

Our roles require in-person time to encourage collaboration, learning, and relationship-building with clients, colleagues, and communities. As an employer, we will be as flexible as possible to support your specific work/life needs.

• Familiarity with relational databases and object storage; exposure to Kafka, NoSQL databases, or event-driven architectures is a plus.
• Experience with monitoring, logging, troubleshooting, and operational best practices.
• Understanding of secure software engineering and data governance principles.
• Fluency in French is mandatory, with a good command of English.

BONUS POINTS IF YOU HAVE:

• Knowledge of machine learning fundamentals and model lifecycle management.
• Experience with MLflow, Kubeflow, or similar MLOps platforms.
• Exposure to Generative AI, vector search, embeddings, RAG pipelines, or LLM serving.
• Experience with Spark, distributed processing, or lakehouse architectures.
• Azure, AWS, Kubernetes, Databricks, or Terraform certifications.
