The Opportunity At SandboxAQ, we operate distinct product teams pursuing different AI technologies. This means our work crosses multiple, highly specialized technical frontiers. Our people strategy—who we hire and how we empower them—is a critical factor in whether we succeed. We are looking for a Principal level People Partner who acts as a "Swiss Army Knife" organizational development expert and executive consultant. In this role, you will work across all business units and collaborate closely with partner functions like Finance, Information Security, Business Operations, and Marketing to drive company-wide objectives. This unique role requires you to constantly zoom in and zoom out. One day you will partner with a business leader to architect a top-down people strategy that aligns with their 3-year product and commercial vision; the next, you will roll up your sleeves to handle a structural reorg or build a localized solution for an acute team issue. You will not be running standard HR programs from an ivory tower. We have a centralized People Operations team that builds our core company-wide programs (like talent reviews and performance management) to provide a solid baseline foundation. Your job is to use that foundation as a springboard to design highly customized solutions for each business unit—ranging from structural redesigns and workflow overhauls to leadership alignment or custom training. Your insights will be critical to informing the content and priorities for company-wide programs and initiatives that help the company prepare for the future. Key Responsibilities Strategic Business Consultation: Partner with business leaders to evaluate whether their current team setup supports their product and commercial vision. You will be accountable for ensuring there is a standardized, actionable "People Plan" for each business unit. High-Velocity Cross-Functional Design: Act as the internal expert on change management and organizational design.
