HR Business Partner

Location: Mason, Ohio
Work Arrangement: Fully On‑Site

Our client is a growing engineering and technology company supporting highly regulated industries. The organization specializes in the design, repair, testing, and lifecycle support of high-reliability electronic systems where quality, compliance, and precision are critical.

The company is experiencing significant growth and expects to substantially expand its workforce over the next several years. As part of that growth, they are bringing Human Resources in-house and are looking for an experienced HR Business Partner to build and own the HR function from the ground up.

This is an excellent opportunity for an HR professional who wants to make a meaningful impact, help shape the culture and processes of a growing organization, and eventually build and lead an HR team.

• Provide guidance on employment laws, regulations, compliance, and employee relations.
• Help develop and update the employee handbook and HR policies.

• Proven ability to operate independently and build HR processes from the ground up.
• Strong judgment, discretion, communication skills, and professionalism.
• Motivated self‑starter who is comfortable wearing multiple hats in a growing organization.
• Someone who is experienced and knowledgeable but still has significant career runway and wants to grow with a company.
• Ability to build trust and establish strong relationships throughout an organization.
• Strong critical‑thinking and problem‑solving skills.
• High sense of ownership and accountability.

Experience in energy, engineering, manufacturing, nuclear, aerospace, defense, or another highly regulated industry would be beneficial, particularly for candidates accustomed to environments with significant compliance and training requirements.

We are not specifically targeting a traditional long‑tenured manufacturing HR manager whose experience has been primarily focused on maintaining an established HR department. The ideal candidate is someone who enjoys building, improving, and being hands‑on.

The organization currently utilizes:

• Horizon Payroll
• Quick Books
• Employee timekeeping/clocking systems
