Data Scientist / ML Engineer — Water Infrastructure

Infinitii ai is a company building machine learning systems to help water utilities and infrastructure operators predict and prevent failures such as sewer overflows, flood risk, and infrastructure breakdowns. The team is small and distributed across Poland and Canada, working on real-world sensor data with significant operational impact.

• Strong data science fundamentals (modeling, validation, interpretation) and solid data engineering skills (pipelines, APIs, data quality)
• Proficiency in Python (must have)
• Comfortable working with ambiguous, messy real-world data
• Nice to have: Go, TypeScript
• Bonus: experience in water/utilities, environmental, or industrial IoT domains
• Bonus: experience with time-series and anomaly detection

• Own the full pipeline-to-model workflow: from raw, messy sensor/telemetry data to production-ready predictive models
• Build and maintain the data pipelines your own models depend on
• Work directly with utility operators and engineers — your models inform real operational decisions
• Shape the approach to anomaly detection, time-series forecasting, and physics-informed ML
• Collaborate across a distributed team (Poland + Canada)
