This isn't a transactional HR role. You'll be a real thought partner to the business, with a seat at the table on workforce planning, org design, talent strategy, and change management.  JOB RESPONSIBILITIES * Coach and advise Customer Success leaders (executives and their directs) on employee engagement, retention, culture, organizational design, and change management.  * Serve as a strategic partner on workforce planning — including build vs. buy decisions, geographic expansion, cost optimization, contingent labor, and M&A — in close partnership with Finance and senior leadership.  * Lead or support change management tied to org design changes: people impact, compensation implications, communication planning, and execution.  * Support leaders in translating employee survey results into meaningful action plans — consulting, advising, and helping drive follow-through, with ownership sitting with the business.  * Stay close to retention risk — conducting exit interviews or proactive pulse conversations as needed.  * Advise on individual people topics (promotions, off-cycles, performance cases, terminations) and manage larger-scale hiring and downsizing initiatives as needed.  * Drive adoption of enterprise talent programs including compensation planning, talent reviews, succession planning, and engagement initiatives.  * Take on HR ad hoc projects as the business evolves.  KNOWLEDGE AND EXPERIENCE * 4-6 years of progressive HR experience, with demonstrated success as an HR Business Partner or similar role.  * Demonstrated ability to serve as a trusted advisor to senior leaders — building credibility quickly and influencing without authority.  * Strong business acumen: you think about people decisions in the context of business outcomes, not just HR best practices.  * Experience with workforce planning, organizational design, and change management in a fast-moving, matrixed environment.  * Ability to work effectively with regional HR partners across geographies and time zones.  * Highly organized with strong communication skills — you can manage multiple priorities and stakeholders without dropping the ball.  * Comfortable with ambiguity and able to drive projects to completion with minimal oversight.  * Ability to facilitate presentations and difficult conversations with senior leadership.  * You're not just AI-curious — you're already using it. You've experimented with AI tools to work faster, think sharper, or solve problems differently, and you're excited about what it means for how HR gets done. You bring a practical perspective on where AI adds value and where human judgment still leads. EDUCATION • Bachelor’s degree in Human Resources or another relevant discipline.
