About the Role

As a Data Analyst on the AI & Threat Analytics team, you will own the entire lifecycle of data collection, preprocessing, and management for machine learning models. Working closely with our engineers, you'll leverage HTML and DOM structures to build and refine datasets, while running feature engineering experiments to enhance our autofill classification models. You'll also generate synthetic datasets using LLMs and explore complex data patterns to optimize model performance. This role is critical to moving our ML initiatives forward by ensuring the team has the highest quality data available.

Responsibilities

• Own the end-to-end data collection, cleaning, and preprocessing process for HTML-based datasets used in machine learning applications.
• Utilize web analysis tools to extract and structure data from DOM environments for model training and validation.
• Collaborate with ML Engineers to support feature engineering experiments, and produce training datasets to meet model requirements.
• Generate and augment synthetic datasets using LLMs to enhance training data balance and availability.
• Analyze data using dimensionality reduction techniques (t-SNE, PCA, UMAP) to explore feature strengths and improve dataset quality.
• Automate data workflows to streamline data processing, manipulation, and transformation.
• Develop and maintain comprehensive documentation for data workflows, processes, and methodologies to ensure lineage, reproducibility, and scalability.
• Create validation/data quality systems to ensure consistency and integrity across all datasets.

• 2+ years of professional experience as a Data Analyst, preferably in a cybersecurity or ML-focused environment.
• Proficiency in Python for data manipulation, analysis (Pandas, NumPy), and automation of data workflows.
• Strong experience with web analysis tools (e.g., Selenium, BeautifulSoup) and a deep understanding of HTML and DOM structures for data extraction and preprocessing.
• Familiarity with natural language processing (NLP) techniques such as tokenization, stop word removal, and lemmatization for text data preparation.
• Experience generating synthetic datasets and using LLMs to supplement machine learning data.
• Ability to collaborate effectively with ML Engineers and other technical teams
• Strong problem-solving skills and a meticulous approach to ensuring data quality and governance.
• Familiarity with cloud platforms (AWS, GCP, Azure) for data storage and processing.
• Bachelor’s degree in Data Science, Statistics, Computer Science, or a related field, or equivalent experience.
• Due to this role’s involvement in GovCloud, all applicants must be a US Person
