About the role

This is PhoenixAI's first full-time HR leader in the U.S. You will build the company's HQ HR infrastructure and lead the U.S. people function for a growing company with teams in the U.S. and APAC. Your job is to set one standard for how PhoenixAI levels, pays, develops, and grows its people across the U.S. and APAC, and to make two teams operate as one company. You are a builder who sets the strategy and is also eager to roll up your sleeves and do much of the work yourself.

What you’ll do

• Partner with HR counterparts in APAC to align job leveling and compensation bands, benefits philosophy, and performance review cadence, while respecting statutory requirements and market norms in each jurisdiction.

• Establish the performance review cycle, expectations, and documentation standard.

• Partner with the VP of Finance and hiring managers to translate the headcount plan into a hiring roadmap, including the GTM hires the company has sequenced behind pipeline growth.
• Set interview standards and keep offers inside the comp bands.

Own the HRO partnership and HR systems

• Serve as the primary owner of the HRO relationship, which manages U.S. payroll, benefits administration and advisory, leave administration, compliance filings, the handbook, and the employee help desk. You set policy and direction, hold them to service levels, and resolve escalations.
• Handle sensitive employee relations matters and final people decisions directly.
• Own Rippling as the HR system of record, with the HRO supporting configuration. Build the people reporting that the founders and VP of Finance rely on.

Unite the U.S. and APAC (China & Singapore) teams culture

• Build programs, rituals, and communication that connect APAC engineering with the U.S. GTM, product, and engineering teams.
• Build connective tissue and a shared culture between our U.S. and APAC teams — helping the two groups work well together across time zones, language, and different working norms, and creating shared rituals and communication practices.

Partner across leadership

• CEO: people strategy, org design, culture, and the leadership team.
• VP of Finance: people budget, headcount planning, compensation, benefits cost, and HRO fees.
• APAC HR Partner: aligning leveling, comp bands, benefits philosophy, and performance cadence across the U.S., China, and Singapore while respecting local law and market norms.
