• Partner closely with Payroll and Benefits teams to ensure accuracy and consistency

Benefits & Leave Support

• Assist with leave administration including FMLA, medical, and parental leave

Building for Scale

• Support performance cycles, engagement initiatives, and people programs
• Contribute to process improvements as we grow and mature
• Assist with HR projects that strengthen how we work as an organization

What We're Looking For

• High attention to detail and respect for confidentiality
• A practical, solutions-oriented mindset
• Comfortable operating in a fast-moving, scaling environment

• Work in a collaborative, low-ego, high-ownership environment
• Real exposure across the full HR lifecycle
• Opportunity to grow as the organization scales
