About Sustainable

HR PEO

Sustainable

HR PEO, LLC is a Madison-based professional employer organization (PEO) that helps small to midsize businesses thrive by simplifying HR, payroll, and benefits. Our team partners directly with clients through a co-employment model, combining deep HR expertise, advanced technology, and personalized service to help them focus on what they do best — growing their business.

We’re a fast-growing, relationship-driven company, and we’re looking to add a Senior Human Resources Business Partner (Sr. HRBP) to our internal team. This is not a client placement — it’s an opportunity to join our own organization and play a key role in shaping how we deliver strategic HR support to our clients.

About the Role

As a Senior HR Business Partner at Sustainable

HR, you’ll serve as a trusted advisor to our client organizations, delivering strategic HR guidance, compliance expertise, and practical people solutions. You’ll collaborate closely with our internal payroll, benefits, and compliance teams to ensure clients receive a seamless and high-touch HR experience.

The ideal candidate is consultative, adaptable, and passionate about helping businesses build strong teams and positive cultures. This role reports directly to Sustainable

HR leadership and includes occasional client travel (typically 2–3 days per trip, with overnight stays).

Key Responsibilities

• Serve as the primary HR contact for assigned Sustainable
  
  HR PEO clients, providing proactive, strategic HR support.
• Advise client leadership teams on workforce planning, organizational design, and talent strategies.
• Guide clients through employee relations, performance management, and compliance matters.
• Develop and refine HR policies, handbooks, and training programs.
• Ensure compliance with employment laws (FLSA, FMLA, ADA, EEO, wage/hour, etc.).
• Partner internally with payroll, benefits, and compliance teams to deliver unified service.
• Analyze HR data and metrics to provide insights and recommendations for clients and internal leadership.
• Support onboarding and implementation for new Sustainable
  
  HR clients.

Qualifications

• Bachelor’s degree in Human Resources, Business Administration, or related field preferred.
• 7+ years of progressive HR experience, including 3+ years in a consultative or business partner role.
• Prior experience within a PEO, HRO, or multi-client HR service model strongly preferred.
• Strong knowledge of HR best practices, compliance, and employment law.
• Excellent communication, relationship management, and problem-solving skills.
• PHR/SPHR or SHRM-CP/SCP certification preferred.
• Willingness to travel occasionally (2–3 days per trip).

What We Offer

• Competitive compensation and performance-based incentives.
• Hybrid work schedule — typically 2–3 days per week in our Madison office.
• Professional development and learning opportunities.
• A collaborative, high-trust culture where your expertise directly impacts our clients’ success.
