Manager, People Business Partner

We're seeking a Manager, People Business Partner to serve as the dedicated HR point of contact for Petra's co-source and lift-out client teams — a population that has more than doubled in the past year to 185+ employees across 20+ distinct client relationships within the U.S. and Canada. Reporting to the Senior Manager, this role is critical to how we scale support for our fastest-growing, highest-touch business unit.

This is a full-time hybrid position based in New York. The expectation is for this individual to work from our Manhattan office 3 days per week.

Key Responsibilities:

• Serve as the primary HR point of contact for Petra's co-source and lift-out client teams, building trusted relationships with client-facing partners and each team's on-the-ground leadership 
• Own and administer bespoke policies and HR terms unique to each co-source and lift-out engagement, ensuring consistency with the underlying client agreement while staying aligned with Petra's broader HR framework 
• Manage and support the lift-out process end-to-end — pre-close diligence and planning, Day 1 transition and onboarding, and post-close integration — coordinating with Partnerships, Legal, and Payroll to ensure a clean handoff into Petra's HR infrastructure 
• Act as the go-to HR resource for the 40+ managers overseeing this population, fielding day-to-day questions, escalations, and policy exceptions specific to each engagement 
• Manage the full employee lifecycle for co-source/lift-out staff — onboarding, performance management, compensation, benefits, leave administration, offboarding — accounting for the specific terms of each client relationship 
• Track growth and utilization trends within this population and flag capacity or relationship-management risks to leadership before they become problems 
• Support performance-cycle execution and compensation planning for co-source/lift-out employees, coordinating between client expectations and Petra's internal processes 
• Maintain data integrity and reporting for this population across HRIS and other HR systems, ensuring accurate headcount, org, and compliance records per client engagement 
• Partner with the Senior Manager and broader People team on ad hoc strategic projects — benchmarking, headcount planning, and HR infrastructure — with a focus on scaling support as this segment continues to grow 

What You'll Need:

• 3–5+ years in HR/People Operations, ideally within financial services, professional services, or another environment involving embedded, outsourced, or client-facing teams 
• Comfort managing multiple concurrent stakeholder relationships with distinct policies and terms — there's no single standard playbook here 
• Hands-on experience with HRIS and performance management platforms (e.g., Rippling, Lattice, or similar); strong Excel/data skills 
• Demonstrated ability to independently manage full-cycle programs and relationships with minimal oversight 
• Highly organized, with excellent attention to detail across a high volume of non-standardized, concurrent arrangements 
• Proven ability to navigate complex and fast-changing organizational structures 
• Clear, professional communicator, comfortable engaging with client-facing partners and senior leadership 
• Ability to professionally handle confidential information with discretion
