  • 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.

Qualifications

  • Bachelor's degree in Human Resources, Business Administration, or a related field preferred.
  • 5+ years of progressive Human Resources experience, preferably in a generalist, HR Business Partner, or HR Manager capacity.
  • 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.
  • Strong communication skills and the ability to build effective relationships with employees and leaders at all levels.
