Senior Data Engineer
- CDI
We're hiring a Senior Data Engineer in Paris, Île-de-France to build and scale data infrastructure using Python, DBT, and PostgreSQL for an AI-driven ClimateTech startup applying generative AI to materials discovery. This is a well-funded (5M+) early-stage startup, developing technology that directly reduces CO emissions in carbon-intensive industries, with strong scientific and commercial momentum.
You'll work closely with the CTO, ML engineers, and scientists to turn complex data into production-ready systems that power ML and LLM applications.
Why This Is Worth Your Time
Own the data engineering foundations behind cutting-edge AI and ML systems
Work at the intersection of data, science, and generative AI
Build core infrastructure from early stage, not maintain legacy pipelines
Equity (BSPCE) in a mission-driven ClimateTech company tackling real-world impact
What You'll Do
Design and build scalable data pipelines in Python for simulation, text, and experimental data
Develop DBT-driven transformations and analytics layers on PostgreSQL
Create internal data tools enabling ML, LLM, and scientific workflows
Implement secure, production-grade data storage to support AI pipelines
Define data governance, lineage, and quality standards
Collaborate with DevOps on cloud infrastructure (AWS or GCP)

Must-haves:
Strong experience as a Senior Data Engineer using Python in production
Hands-on experience with DBT, PostgreSQL, and modern data modeling
Experience building data infrastructure for ML or AI-driven products
Nice-to-haves:
Exposure to ML pipelines, LLM systems, or AI infrastructure
Experience working with scientific or experimental data
