Manager, People Business Partner

We're seeking a 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 scaling support for our fastest-growing, highest-touch business unit. This is a full-time hybrid position based in New York, with an expectation to work from our Midtown Manhattan office 3 days per week.

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.

Requirements

• 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.

Pay

The compensation range for this position is $110,000 – $130,000 per year. This range represents the base salary only. Actual pay will depend on factors such as qualifications, experience, and skills.

Benefits

• 90% covered medical, dental, and vision insurance premiums.
• Fully funded Health Savings Account (HSA) employer contributions up to the IRS maximum—available to employees enrolled in our high-deductible health plan (prorated for new hires).
• 401(k) employer match at 100% of your contributions up to 5% of compensation, with immediate vesting.
• Flexible paid time off to recharge, travel, or take care of what matters most.
• Generous holiday calendar to ensure you have time to rest, reflect, and celebrate throughout the year.
• Hybrid work environment that offers flexibility and supports work-life balance.
