About Clockwork Systems

Clockwork.io – Software Driven Fabrics to increase GPU cluster utilization

Clockwork Systems was founded by Stanford researchers and veteran systems engineers who share a vision for redefining the foundations of distributed computing. As AI workloads grow increasingly complex, traditional infrastructure struggles to meet the demands of performance, reliability, and precise coordination. Clockwork is pioneering a software-driven approach to AI fabrics by delivering cross-stack observability to catch and quickly resolve problems, workload fault tolerance to keep jobs running through failures, and performance acceleration that dynamically routes and paces traffic to avoid congestion.

About the Role

As our Senior HR Manager, you'll be the cornerstone of Clockwork's people function. This is a high-impact, hands-on role for someone who thrives in the builder phase: you'll own the full HR lifecycle, elevate our people programs, and serve as a trusted partner to leadership and employees alike. You'll work closely with our executive team to shape the culture, policies, and infrastructure that will carry us through our next phase of growth — including our teams in the U.S. and UK.

• Partner with our PEO on payroll, benefits administration, and HR compliance.
• Serve as the primary point of contact for employee relations, resolving issues with empathy, fairness, and good judgment.

Programs & Policy

• Design, implement, and continuously improve HR policies, employee handbooks, and operational processes that scale with the company.
• Lead compensation benchmarking, benefits strategy, and rewards programs to keep Clockwork competitive in the AI/infrastructure talent market.
• Build and deliver onboarding, training, and manager development programs that reinforce our values and accelerate employee effectiveness.

Compliance & Legal

• Ensure compliance with federal, California, and UK employment laws and regulations.
• Oversee employment-based immigration programs (H-1B, green cards, etc.) in partnership with outside counsel.
• Proactively identify compliance risks and implement controls before they become problems.

Strategic Partnership

• Partner with leadership on workforce planning, org design, and headcount strategy as we scale.
• Track and report on people metrics (attrition, engagement, hiring velocity) and surface actionable insights.
