People Operations Coordinator

About Us

We’re building a dynamic and collaborative team that values autonomy, integrity, and fast-paced execution. As we scale, we’re looking for a People Operations Coordinator looking to elevate their skills and support our People Operations team.

About the Role

We’re seeking a self-starting, detail-oriented People Operation Coordinator with a minimum of 3-5 years of experience in HR or People Operations. You’ll be stepping into a position that requires confidence with HR fundamentals and a strong ability to operate independently. You’ll support our People Operations Lead and help drive day-to-day HR functions, from onboarding and compliance to benefits coordination and HR systems management.

You’ll thrive in this role if you’re energized by fast-moving environments, enjoy solving problems autonomously, and feel comfortable supporting a distributed workforce.

Responsibilities

• Support the employee lifecycle: onboarding, offboarding, and leaves of absence.
• Maintain and audit HR systems and employee records (e.g., Rippling).
• Assist with benefits administration, open enrollment, and employee questions.
• Maintain documents such as offer letters, I-9 verifications, and policy acknowledgments.
• Respond to HR-related inquiries, and confidential situations when needed.
• Assist with compliance tracking (e.g., training, employment eligibility, state law updates).
• Support ad hoc projects such as policy updates, audit prep, and reporting.
• Partner with managers and cross-functional teams to provide a positive employee experience.

Requirements

• 3-5 years of experience preferred in HR, People Operations, or similar function.
• Serve as a trusted first point of contact for employees, handling inquiries with professionalism, discretion, and a high degree of autonomy.
• Demonstrates strong organizational skills and sharp attention to detail, ensuring accuracy across tasks and documentation.
• Effectively manages multiple priorities and deadlines in a fast-paced, dynamic environment.
• Comfortable navigating tools such as Google Workspace, Slack, and Rippling; quickly adapts to new systems and workflows.
• Maintains a working knowledge of employment laws, I-9 compliance requirements, and HR best practices to support compliant and consistent operations.

Nice to Have

• Previous experience in a start-up or high-growth company (as we value fast-paced execution).
• Exposure to global HR operations or contractors (as we scale).
• Interest in scaling HR processes and documentation and continuous improvement.
