Job responsibilities

• Partner with stakeholders, business leaders, cybersecurity engineers, and data engineers to understand security needs, define use cases, and acquire the data required to address them.
• Perform exploratory data analysis on security and technology datasets, identify meaningful patterns, and communicate findings to stakeholders.
• Select, develop, and evaluate statistical, machine learning, deep learning models that are appropriate for cybersecurity use cases and business outcomes.
• Prepare model-ready datasets through feature engineering, data quality assessment, and other data preparation techniques.
• Leads reuse-first adoption of enterprise-authorized AI capabilities within the work environment to accelerate data architecture and model analysis and strategic decisioning, with human-in-the-loop validation and appropriate handling of sensitive data.
• Establishes portfolio-level guardrails for AI-assisted and agentic workflows used in data engineering design and delivery, including traceability/auditability and control expectations aligned to resiliency and security standards.
• Support model governance by documenting model selection, interpretability, testability, performance, limitations, and results.
• Design, build, review, debug, and maintain secure, high-quality production code for analytical and machine learning solutions.
• Contribute to security control effectiveness by applying industry insights, internal standards, and regulatory expectations to improve security processes and protocols.
• Add to a team culture of diversity, equity, inclusion, and respect.

Required qualifications, capabilities, and skills
