ABOUT THE ROLE

This is our first dedicated HR Operations hire, reporting to the Head of Business Operations & People. You will own the operational backbone of the People function — payroll, benefits, and HR compliance — and serve as the company’s frontline for employee relations.This role owns the execution, recordkeeping, and day-to-day judgment calls that keep the company compliant and employees well taken care of and equipped to do their jobs well.

You should be excited to build HR infrastructure from 0->1 at a fast-moving, talent-dense company. You will be the go-to person that employees trust at the ground level. You are an advisor and advocate for HR, who balances strong people skills with judgment to protect the company against compliance risk.

WHAT YOU'LL DO

• Own end-to-end payroll operations — accuracy, timeliness, and compliance, including coordination with finance on payroll funding and reporting.
• Administer employee benefits programs — plan selection, open enrollment, vendor management, and day-to-day employee support.
• Serve as the company’s HR compliance lead — employment law (CA and any additional jurisdictions as we grow), visa sponsorship program management, leave administration, I-9 and recordkeeping, policy documentation, and audit readiness.
• Be the first point of contact for employee relations — conflict resolution, performance concerns, and workplace investigations — handled with empathy, discretion, and sound judgment.
• Build and maintain HR policies and the employee handbook, keeping them current with the law and reflective of AfterQuery’s culture.
• Own the accuracy and integrity of HR and payroll systems (HRIS, payroll, benefits platforms) as the single source of truth for people data.
• Champion HR/People's role within the company — proactively communicating what the function does, why it matters, and how to engage with it, so employees see People Ops as a resource.
• Treat People Operations as a service function — fast, accurate, and low-friction — without cutting corners on compliance.

WHAT WE'RE LOOKING FOR

• 5–8+ years in HR generalist, HRBP, or HR operations roles, with direct, hands-on ownership of payroll, benefits, and compliance — not just oversight of vendors.
• Deep working knowledge of California employment law and wage-and-hour rules; comfortable getting up to speed on additional states as the company grows.
• Demonstrated judgment handling sensitive employee relations matters — you can hold both the company’s interests and an individual employee’s perspective at the same time.
• Genuine empathy paired with discretion: people trust you with hard conversations because you listen first and act with fairness.
• High ownership instincts; you’ve built or meaningfully rebuilt HR infrastructure at a small or fast-growing company, not just operated within an existing one.
• Track record of leading change management for new policies, systems, or programs — you know how to build buy-in and drive adoption without over-engineering.
• Clear, calm, written-first communicator who can document decisions and policies without unnecessary process.
• Thrives in a fast-paced, high-growth environment where priorities shift quickly.
• Prior experience working at a startup.
• Comfortable in a 5-day in-office SF environment that prizes speed and direct feedback.

BONUS

• Experience supporting HR compliance for a workforce that includes both full-time employees and contractor/expert population.
• SHRM-CP/SHRM-SCP or PHR/SPHR certification.

WHY AFTERQUERY

• You’ll lead and own People operations — payroll, benefits, compliance, and employee relations — as part of a small, supportive, dynamic team, partnering closely with the Head of Business Operations & People.
• Real ownership over the systems and decisions that shape every employee’s day-to-day experience, with people around you who care about getting it right.
• You’ll have a voice at one of the most consequential companies in the AI training-data category, with the backing and trust to run your area your way.
• A small, dense team with high standards. We hire people we’d be sad to lose, and we work hard to keep them.
