This is an exciting opportunity to develop your technical skills while contributing to meaningful, high-impact projects. You will gain hands-on experience with modern data engineering tools, cloud infrastructure, and collaborative data science workflows, all while working in a supportive and mission-driven environment.

The person

In this role, you will:

• Develop and maintain Python data pipelines to collect, clean, and process data at scale, ensuring robustness, reliability, and efficiency.
• Work with data scientists to enable efficient model training and deployment.

• Ability to develop LLM-based tools/products (e.g., RAG workflows).
• Familiarity with version control tools such as Git/GitHub.

In addition, we are particularly interested to hear from candidates who have:

• Exposure to cloud platforms (e.g., AWS, GCP, or Azure).
• An understanding of DevOps concepts such as Infrastructure as Code, CI/CD, or MLOps.
• Knowledge of Python-based data pipeline frameworks (e.g. Airflow, Metaflow) and Python-based product development packages (e.g. FastAPI, Streamlit).
