Job Description:

We are looking for a strategic, but hands-on, Senior HR Manager who brings a deep HR generalist foundation and a track record of building people programs from the ground up in startup, established and high-growth environments. This person has ideally helped scale an organization from early-stage through 200 or more employees and knows what it takes to go from informal to intentional across every HR function. You’ll be joining us at a critical inflection point. NSTXL is scaling rapidly with new business wins and lines of service.

The primary focus of the Senior HR Manager will be helping lead the design, build-out, and ongoing evolution of the policies, processes, and programs that support a growing organization, including talent acquisition, workforce planning, performance management, HRIS and people technology, DEI, total rewards, HR analytics and reporting, policy development, leave and accommodation management, employee relations and compliance. This is not a role where strategy gets handed off to someone else to implement. We expect this person to define the approach and own the execution, all while keeping culture and employee experience at the center. Experience formalizing HR infrastructure in a high-growth, startup environment is a requirement for this role. Candidates who have not built people programs from the ground up in that context will not be considered.

You'll report to and work closely with the VP of Human Resources and partner with managers and leaders across the organization. This is a highly collaborative role for someone who enjoys building strong relationships, supporting teams, and helping organizations grow thoughtfully.

What You'll Do:

Culture & Engagement

• Build strong relationships across the organization and maintain a deep understanding of employee experience and team dynamics
• Help design and continuously improve a structured onboarding program that sets new employees up for success from day one and reflects NSTXL’s culture and values, including role-specific onboarding paths, 30/60/90 frameworks, and structured check-ins.
• Develop and expand the policies, programs, and people practices, including formalized feedback channels and engagement surveys

Manager Support & Employee Development

• Partner with managers on complex people situations like difficult conversations, feedback, and accountability, while building resources and toolkits that grow their confidence and independence over time, within the legal constraints that shape those decisions.
• Design and deliver manager training programs that equip people leaders with the skills they need to lead effectively
• Build and improve performance and development practices that support clear expectations, strong feedback, accountability, and employee growth
• Build out a learning and development strategy and program infrastructure that supports employee growth at every level, including new manager development, career pathing frameworks, and access to learning resources that scale with the organization
• Partner with managers and leaders to strengthen leadership effectiveness and build a culture of continuous learning across the organization

Employee Relations & Investigations

• Serve as the primary point of contact for employee relations matters, including concerns, complaints, and escalations
• Lead workplace investigations from intake through resolution, including documenting findings, recommending corrective action, and ensuring appropriate follow-through in a way that protects both the individual and the organization
• Build and maintain clear employee relations frameworks

HR Operations & Compliance

• Ensure compliance with federal, state, and local employment laws and evolving HR best practices, staying ahead of changes that affect a growing, multi-state or distributed workforce
• Develop, expand, and maintain a comprehensive set of HR policies and employee handbook materials that reflect NSTXL’s values, operational needs, and legal requirements, and that scale alongside organizational growth
• Build and maintain a compliance training program that ensures all employees and managers meet required training obligations, with scalable resources and infrastructure that grow with the organization.
• Partner with the VP of Human Resources on benefits strategy, including evaluating plan competitiveness, supporting open enrollment, communicating program value to employees, and recommending enhancements that align with NSTXL’s growth and workforce needs
• Build and maintain HR process documentation that allows the team to operate consistently and efficiently, including standard operating procedures, templates, and guides that support day-to-day operations and reduce reliance on institutional knowledge held by individuals

Talent & Growth Strategy

• Help evolve NSTXL’s hiring practices, candidate experience, and talent systems as the organization grows

Required Experience

• 7+ years of progressive HR experience, including at least 5 years in a senior generalist or HR Manager role
• Demonstrated experience supporting organizations through startup and high-growth phases, ideally having helped scale from early-stage to 200 or more employees, with hands-on ownership of building HR programs where little or no formal infrastructure previously existed
• Deep generalist experience across all core HR disciplines
• Proven experience building policies, processes, and programs from scratch in environments where the work was not handed to you; you have personally designed the frameworks, written the documentation, and created the programs that others now use
• Experience conducting or overseeing workplace investigations and managing complex employee relations
• Experience directly managing and developing employees or small teams
