    About the role#

    This internship focuses on building the foundations of proactive intelligence within the Apollo team. You will own a research problem end-to-end, from framing the initial question and running experiments to publishing findings and shipping work into production systems.

    • Own a research problem end-to-end: framing the question, developing methods, running experiments, and publishing findings.
    • Focus on building rich representations of customers from event streams, financial activity, operational signals, and behavioral data.
    • Develop systems that can anticipate customer needs and initiate helpful actions before being asked.
    • Build agents that reason over customer world models and take actions in real environments.
    • Develop methods that allow intelligence to improve continuously from real-world outcomes.

    What you'll need#

    • Currently enrolled in an MS or PhD program in Computer Science, Machine Learning, Statistics, Mathematics, Operations Research, or a related field, with plans to return to the program after the co-op.
    • Strong foundations in modern machine learning, including deep learning, optimization, representation learning, and foundation models.
    • Experience conducting independent research and translating ideas into working systems.
    • Fluency in Python and experience with PyTorch, JAX, or similar frameworks.
    • Evidence of research excellence through publications, open-source contributions, technical leadership, or equivalent work.

    Location & details#

    • Employment: Full-time, paid internship.
