Human Resources Manager

About the Role

We're carving out a dedicated Human Resources Manager role as a build-and-run, hands-on individual contributor position. You'll own the full people function across our US and international entities (100–200 employees today, growing) with real autonomy and the mandate to move things forward. This role requires someone comfortable making decisions, owning outcomes, and working flexibly across finance, operations, commercial, and leadership—a builder who happens to run HR.

Responsibilities

• Payroll & HR Systems
  • Manage the US payroll provider (e.g., ADP) and coordinate international payroll through local bureaus/providers in each country we operate in—ensuring accuracy, timing, and compliance across all entities.
  • Own the HRIS: data integrity, reporting, and the systems that make the rest of the function scale.
• Benefits & Compensation
  • Own US benefits administration end-to-end: health plans, 401(k), open enrollment, and the annual broker relationship.
  • Administer compensation: bands, offers, changes, and keeping practices consistent and defensible across entities.
• Employee Lifecycle & Onboarding
  • Design and run onboarding so new hires—including those joining through acquisitions—are productive and supported from day one.
  • Own the full lifecycle: offboarding, transfers, documentation, and the records behind them.
• Performance & People Operations
  • Build and administer the performance-review cycle, timelines, and cadence.
  • Serve as the point of contact for employee relations, coaching managers and resolving issues before they escalate.
• M&A Integration
  • Partner with deal teams to integrate acquired companies—domestic and international.
  • Harmonize payroll and benefits, onboard acquired employees, map org structures, coordinate with local HR/payroll partners, and stand up consistent HR processes across newly combined entities.
• Compliance
  • Maintain US multi-state employment compliance.
  • Manage international labor-law obligations across the countries we operate in (starting with our France-based FAMECO group and extending to future acquired entities) in partnership with local counsel and in-country payroll/HR providers. You coordinate and own the outcome; you are not expected to be a subject-matter expert in every country's employment law.
• Recruiting
  • Coordinate hiring logistics, job postings, and the candidate process while hiring managers lead their own searches; partner with external recruiters as needed.

What Makes This Role Different

• Autonomy by design: You'll set up processes the company doesn't have yet. We're not looking to approve every decision.
• Cross-border, multi-entity: You'll operate across US and international entities and manage everything acquisitions throw at us, in whatever geography they land.
• A seat close to the top: Reporting to the CFO, you'll have direct visibility and influence with leadership.

Requirements

• 8+ years of progressive HR experience, including ownership of payroll (via provider), benefits, and compensation administration.
• Experience running HR as a generalist across the full employee lifecycle.
• Comfort operating autonomously—you can build a process from scratch and drive it to completion.
• Multi-state US employment compliance experience.
• Strong systems and data orientation (HRIS, reporting, payroll platforms).

Preferred Qualifications

• Exposure to M&A / acquisition integration, or experience in a high-growth, multi-entity, or PE-backed environment.
• International / multi-country HR experience, or a demonstrated ability to manage cross-border compliance and payroll through local partners.
• Experience standing up or coordinating HR in new geographies is a strong plus.
• SHRM-CP/SHRM-SCP or PHR/SPHR certification.
• Additional language ability is a plus, but not required.
