• Act as a key point of contact for HR and operational queries, resolving issues efficiently and escalating when required.
• Manage SOWs, Change Orders, signatures, and documentation to ensure complete and accurate records.
• Continuously improve operational workflows, documentation, and internal processes to make them more efficient and scalable.
• Build and maintain automation and workflow improvements that reduce manual work, data entry, and errors.

• Comfortable working with HRIS, payroll, expense, e-signature, and other business systems.
• Experience using automation tools to reduce manual processes and improve data accuracy.
• Comfortable working in a fast-paced, growing, and internationally distributed environment.
