• Partner with managers to ensure HR processes, policies, and programs are implemented consistently and effectively.
• Maintain HR records, reporting, compliance requirements, and recurring HR activities.
• Identify opportunities to simplify, automate, and improve HR processes, with a focus on reducing administrative work and improving the employee and manager experience.
• Develop and maintain HR processes, tools, documentation, and standard work that create greater consistency and efficiency.
• Support workforce planning, organizational initiatives, and other strategic HR projects in partnership with the Director of Human Resources.
• Provide support for additional HR priorities and projects as the needs of the business evolve.

• Broad working knowledge of HR practices across recruiting, onboarding, benefits, leave administration, performance management, HR systems, and employment compliance.
• Experience working in a manufacturing, industrial, or similar operational environment preferred.
• Experience with Workday HRIS strongly preferred.
• Strong organizational skills and the ability to manage multiple priorities in a fast-paced environment.
• Demonstrated ability to identify inefficient processes and develop practical, sustainable improvements.
