People Operations & Workplace Manager

About the role

We're growing fast — and we need someone who thrives in that. interface.ai is scaling our San Francisco office from 15 to 50 people in the coming months, with a global team approaching 200 by year end. This is a founding role for People Operations in the US, and we're looking for someone who is equal parts operator, community builder, and strategic partner.

Responsibilities

• Build and run a best-in-class onboarding experience that makes every new hire feel set up, welcomed, and genuinely excited from Day 1
• Own HR operations end-to-end in the US: offer letters, policies, employee records, benefits administration, and compliance across federal and California regulations
• Lead office space strategy — evaluate, negotiate, and manage our SF workspace as we scale, including vendor and facilities relationships
• Create and maintain workplace programs, team events, and cultural touchpoints that bring our values to life in-person
• Partner with the Head of People on talent and people strategy as we grow from 125 to 200+ globally
• Build scalable systems and processes from scratch — you'll be the first US HR Ops hire, so this is a blank canvas
• Serve as the heartbeat of the SF office; you'll know everyone by name, notice what's working (and what isn't), and take action

Qualifications

• 4+ years of experience in People Operations, HR, or Office Management — ideally in a high-growth tech startup environment
• Working knowledge of California employment law and HR compliance; you don't need to be a lawyer, but you need to know when to call one
• Experience owning or co-owning an office space — vendor management, space planning, facilities decision-making
• Exceptional organizational skills paired with the flexibility to pivot when the day goes sideways (and it will)
• Strong communicator — warm and approachable with employees, professional and precise with stakeholders
• A builder mentality: you see gaps and fill them, you see inefficiencies and fix them, and you don't wait to be asked
• Genuine enthusiasm for culture — you think about what makes a workplace special and take that seriously
• Comfort operating with autonomy in an ambiguous environment; you have strong instincts and the confidence to act on them

Bonus Points

• Experience scaling a team through a hyper-growth period (doubling or tripling headcount)
• Background in setting up HR infrastructure from the ground up at a startup
• Familiarity with HR and ATS platforms (Rippling, Greenhouse, Lattice, Ashby or similar)
