Promptfoo is the leading AI security testing platform, helping 250,000+ developers build secure, reliable AI applications.

Backed by Insight Partners and Andreessen Horowitz, we help the world’s largest enterprises adapt AI-specific pentesting techniques to your application, providing automated red teaming, vulnerability scanning, and continuous monitoring for LLM-based systems.

You will own our talent engine and core people operations as we scale from 17 to 50+ employees over the next 12 months. You'll run end-to-end recruiting, sourcing, closing, and coordinating external recruiters, build the essential people infrastructure (onboarding, comp, performance) that keeps a fast-growing team aligned and effective, and help shape culture deliberately as we grow.

What You'll Do

Recruiting and hiring

• Own end-to-end recruiting: process, pipeline, scheduling, scorecards, interview kits, SLAs, weekly funnel reviews

• Manage and coordinate external recruiters: negotiate agreements, run weekly syncs

• Track metrics: pass-through rates, time-to-hire, offer acceptance, quality-of-hire, cost-per-hire, first-90-day ramp, regretted attrition

People ops and compliance

• Maintain HR compliance

• Run hybrid onboarding with run-books for in-office and remote hires. Build 30/60/90 templates

• Manage PEO relationship, handbook, and benefits

• Coordinate team events, manage travel logistics, handle miscellaneous people ops

Comp, leveling, and performance

• Build leveling framework and pay bands

• Document promotion criteria and refresh/equity policy

• Implement light quarterly reviews/formal annual reviews, ongoing feedback loops, and manager toolkits

• Partner with Finance on headcount planning

Culture and coordination

• Design rituals that reinforce company values and make hybrid work effective

• Run engagement pulses

• Host candidate onsites and coordinate team offsites

What We're Looking For

• 5-7+ years in People Ops and recruiting, with at least one early-stage tour (Series A-C)

• Proven track record building recruiting engines, including sourcing candidates / recruiters, structuring interviewing processes, and closing candidates, and raising hiring quality at startups

• Experience managing external recruiting agencies

• California compliance literacy: harassment training, pay-range transparency, wage-hour basics, CPRA requirements

• Comp and equity fluency with Carta, Pave, or similar benchmark tools; experience with HRIS platforms like Rippling and ATS systems like Ashby

• Full-cycle recruiting experience: sourcing, closing candidates, structured interviews

• Strong operations skills: ability to manage multiple moving pieces and prevent things from falling through cracks

• Clear, concise communicator, data-driven, and high agency

• Nice to have: experience with hybrid teams, technical recruiting for engineering roles

What Makes This Role Unique

• You're the first People hire. This is a greenfield opportunity to build systems from scratch. You'll have direct partnership with the CEO and leadership team to shape how we hire, grow, and operate

• We have strong product-market fit and traction. 250,000+ developers use our open-source tools, 85 Fortune 500 companies rely on us for AI security, and we just raised a $18.4M Series A from a16z and Insight Partners

• You'll work on problems that matter. AI security isn't theoretical; our customers include major financial institutions, healthcare companies, and government contractors who need to ensure their AI systems are safe and secure. The talent you bring in will be working on infrastructure that protects real systems from real risks

• Immediate impact and ownership. In 12 months, you'll have built the recruiting engine, people systems, and cultural foundations that will carry the company to 100+ employees

• Technical and mission-driven talent. You'll be recruiting engineers and ML experts who care deeply about open-source, developer tools, and security
