• Contribute to roadmap planning, technical debt reduction, and operational maturity initiatives.

• Develop and maintain documentation, standards, and runbooks for data pipelines and infrastructure.

• Promote reuse and standard patterns across CD&A engineering.

Collaboration & Governance

• Work closely with Cyber Defense (CFC/SOC), XDR/SIEM engineers, Cloud Security, Platform Engineering, and Compliance teams.

• Support audit, compliance, and data retention requirements impacting security telemetry.

• Provide technical input into architecture decisions, onboarding reviews, and platform changes.
