•Experience designing or contributing to production model monitoring or performance tracking
•Comfort working with cloud platforms such as GCP, AWS, or Azure, Docker, and Airflow
•A strong analytical foundation and a background in mathematics, physics, computer science, engineering, or equivalent experience
Nice to have
•Snowflake or similar cloud data warehouses
•Generative AI application development, including API integration, RAG systems, agentic AI concepts or frameworks such as LangChain agents or CrewAI, and simple user interfaces such as Streamlit
Conditions
•Minimal travel required (up to 5%)
•Annual bonuses and incentives, health and wellbeing benefits, paid time off, retirement plans, insurance coverage, and other local or statutory benefits may be available depending on role and location
