You will work closely with cross-functional teams to uncover insights, solve complex problems, and drive data-informed decision-making.

Requirements

Master’s degree in computer science/engineering.
4-5 years of experience in data science or a related field.
Strong proficiency in Python programming language.
Experience with data analysis and visualization tools (e.g., Pandas/Polars, NumPy, Matplotlib, Seaborn).
Knowledge of machine learning algorithms and techniques.
Familiarity with deep learning frameworks (e.g., TensorFlow, PyTorch).
Experience with natural language processing (NLP) and large language models (LLMs) is a plus.
Strong problem-solving and analytical skills.
Excellent communication and collaboration skills.
Applicants must be authorized to work in the US.

Nice To Haves

Experience with Go/Rust programming language.
Experience working with threat modeling and detection, anomaly detection or related fields is a bonus.
