About The Position

The Senior HR Business Partner will serve as a strategic advisor to functional leaders across technical and non-technical teams. This role is responsible for driving organizational effectiveness, supporting high-performance standards, and guiding leaders through complex people decisions. This foundational role will help build the HRBP function from the ground up: establishing core management toolkits, strengthening org design rigor, advising on performance and flight risk, and acting as connective tissue between leaders and the broader People team. You’ll help ensure we scale with intentionality, high performance, and sound judgment, while laying the groundwork for future org growth. You'll be a true partner to the founding team and business leads — not an administrator. You'll help us organize and scale the company, give direct feedback to managers, steer important people decisions, and build the infrastructure that lets everyone do the best work of their careers. You'll own the full employee lifecycle, stand up our first people systems, and operate with urgency across whatever's most important each week.

Requirements

6–10 years as an HR generalist or HRBP, with meaningful time supporting technical teams at a high-growth startup
Comfortable in ambiguity and can pull relevant signal out of complex situations and make sound decisions without waiting for a playbook
Strong analytical and problem-solving skills; you assess situations using data while drawing from experience
Outstanding interpersonal and influencing skills across all levels — from ICs to founders
Deep California employment law fluency (CFRA, FEHA, FMLA) and US employment practices
Demonstrated ability to coach managers through complex and difficult situations directly and constructively
Experience with global or multi-state workforces and familiarity with immigration/visa processes
