Human Resources Manager

A well-established, employee-owned general contractor with a long-standing reputation for excellence is seeking a hands-on HR Manager to build and lead their HR function from the ground up. This is a rare opportunity to step into a true “blank slate” role—owning and shaping HR strategy, processes, and infrastructure for a tight-knit, highly tenured team of 140 employees.

Why This Role Stands Out:

  • Build something from scratch – no legacy HR structure to untangle
  • High visibility – work directly with executive leadership
  • Stable, established company with decades of success in complex construction projects
  • Employee-owned organization (ESOP) with strong long-term incentives
  • Opportunity to make a lasting cultural and operational impact

This is a one-person HR department (with payroll support) responsible for designing, implementing, and owning all HR functions across the business.

You’ll step into a company with strong foundations but no formal HR infrastructure, giving you full ownership to:

  • Build and implement HR policies, processes, and best practices
  • Manage benefits administration, including open enrollment
  • Oversee employee relations across a tenured workforce
  • Partner closely with leadership on compliance, performance, and culture
  • Support payroll and ensure alignment with HR processes
  • Maintain and evolve the employee handbook and internal policies
  • Handle workers’ comp, compliance, and reporting (including ESOP-related responsibilities)

What They’re Looking For:

  • 5+ years of HR experience, ideally in construction or a similar field environment
  • Experience building or revamping HR processes from scratch (or being the first HR hire)
  • Comfortable operating as a true standalone HR leader
  • Thick-skinned, direct communicator who can navigate a no-nonsense culture
  • Proven longevity and stability in prior roles (this is critical)
  • Bachelor’s degree required; HR certifications are a plus
  • Must be comfortable working onsite in NYC

Compensation & Benefits:

  • Base plus annual bonus
  • Employee Stock Ownership Plan (ESOP) with strong contribution potential
  • 401(k) with match
  • Comprehensive medical (high employer contribution), dental, and vision
  • 11 paid holidays + generous PTO
  • Long-term stability within an employee-owned company

Culture Snapshot:

  • Direct, straightforward communication style
  • Highly tenured workforce with strong institutional knowledge
  • “Roll up your sleeves” environment—not for someone who wants a purely strategic role without execution
  • Built for someone who thrives in ownership, autonomy, and accountability

If you’re someone who wants to own HR end-to-end, build real structure, and leave a lasting mark on a growing organization, this is the role.

We look forward to reviewing your application!
