Why work at MITER Brands?

We’re looking for a trusted advisor and strategic partner with 7–10+ years of HR leadership, including experience in manufacturing environments and managing HR teams.

In this role, you’ll lead and deliver critical HR initiatives that align with business objectives—supporting a dynamic workforce through programs in employee engagement, onboarding, talent development, safety, retention, change management, and leadership coaching. You’ll oversee a small HR team and serve as a key culture champion on-site.

This is more than an HR role—it’s your chance to shape culture, drive results, and lead with purpose in a company where excellence is truly a team sport.

You understand the importance of being a people-facing HR leader with regular presence on the production floor and willing to flex your schedule to provide in-person support for off shifts. 

You’ll bring expertise across employee relations (investigations, documentation, timeliness and equitable resolution), employee engagement, change management, onboarding, safety, compliance, and leadership development.

Strong candidates will be consultative, data-informed, and action-oriented, with a passion for building culture and influencing outcomes at all levels including but not limited to developing, coaching, and mentoring site leaders, workforce and succession planning, and team member relations and retention.

At MITER Brands, people matter—our values are lived through teamwork, respect, continuous improvement, and opportunities to grow. If you’re ready to make an impact and help shape a high-performing, values-driven workplace, we want to meet you.
