• Policy & Compliance Ownership: Develop, review, and update HR/ER policies and training programs to ensure compliance with local employment laws (US, UK, DE, Japan) and reinforce Flatiron's values and best practices.
• Process Design & Operational Excellence: Build and continuously improve scalable ER systems (case trackers, templates, workflows) to ensure clean documentation, audit readiness, and reduced administrative burden on HRBPs and managers.
• Insights & Pattern Recognition: Use ER case data to identify trends, surface systemic risks, and proactively recommend solutions. Partner with HRBPs to inform broader people strategies based on case patterns and employee sentiment.
