Job Description

Human Resources Manager (Onsite – North County-San Diego, CA)

Full-Time | $100,000 – $130,000 Base + Bonus

A well-established, growing manufacturing company in North County San Diego is seeking a hands-on HR Manager to lead and scale the HR function. This is an urgent, high-impact role supporting ~100 local employees, with a strong emphasis on culture, compliance, and operational excellence.

This company has been in business for decades, with a reputation for employee longevity, stability, and a values-driven culture. As they continue to grow, they are looking for an HR leader who can own the function end-to-end and serve as a trusted partner to leadership.

Why This Role

• High visibility role reporting directly to executive leadership
• Opportunity to build, shape, and modernize HR in a growing organization
• Strong, people-first culture with long-tenured employees
• Ability to make an immediate impact in a business-critical position

Key Responsibilities

HR Operations & Compliance

• Lead all HR operations with a strong focus on California employment law compliance
• Oversee policies, procedures, employee relations, and risk mitigation
• Ensure compliance with wage & hour laws, timekeeping, and employment regulations
• Partner with leadership on HR governance and best practices

Employee Relations & Culture

• Serve as the primary HR resource for a diverse workforce
• Maintain and strengthen a strong, collaborative company culture
• Conduct investigations and advise managers on employee issues

Talent Acquisition & Onboarding

• Own full-cycle recruiting and onboarding efforts
• Partner with hiring managers to improve hiring quality and speed

Compensation, Benefits & Payroll

• Administer benefits programs and support compensation processes
• Oversee payroll in partnership with finance (hands-on involvement required)
• Manage vendor relationships (brokers, benefits providers, etc.)

Performance & HR Strategy

• Lead performance management and employee development initiatives
• Partner with leadership on workforce planning and scaling HR infrastructure

What We’re Looking For

• 5–10+ years of progressive HR experience
• Strong knowledge of California labor laws and compliance
• Proven experience in HR operations, employee relations, and recruiting
• Hands-on, self-starter mentality—someone who enjoys rolling up their sleeves
• Ability to work onsite and be embedded in the business

Preferred (Not Required)

• Spanish language skills (ability to support a Spanish-speaking workforce)
• Experience in manufacturing or similar environments
• HR certification (SHRM, PHR, etc.)

Ideal Candidate Profile

This role is perfect for someone who:

• Wants ownership of the HR function, not just a piece of it
• Thrives in a lean, entrepreneurial environment
• Values company culture and employee engagement as much as compliance
• Is equally comfortable in strategy and day-to-day execution
