Senior People Operations Specialist

The Role:

We’re looking for a Senior People Operations Specialist to own and optimize the day-to-day execution of our People Operations as we scale. This role is critical to bringing structure, consistency, and operational excellence to a People function that has grown quickly and now needs strong foundations.

This is an individual contributor role with broad responsibility across core HR operations. The ideal candidate has enough prior HR experience to operate independently, exercise sound judgment, and handle sensitive employee matters with discretion, while still being highly hands-on and execution-focused. This individual will run core HR processes end to end, standardize what exists today, and build clear, scalable SOPs to support a growing, increasingly global workforce. We are looking for someone who can leverage documentation, automation, and AI-powered productivity tools to reduce manual effort and improve efficiency.

Responsibilities:

• Own and execute day-to-day People Operations across the full employee lifecycle, including onboarding, job changes, leave of absence administration, and offboarding/terminations (administrative support).
• Run end-to-end onboarding for new hires, including systems access, documentation, audits, and coordination of new hire orientation.
• Maintain accurate, compliant employee records and ensure data integrity across HR systems and files.
• Support federal, state, and local HR compliance activities, including annual filings and reporting (e.g., EEO-1, ACA).
• Manage operational governance and audits, including I-9s, policy acknowledgments, onboarding/offboarding records, and leave documentation.
• Own small projects and provide operational support for benefits, compensation, and payroll processes, partnering closely with vendors and internal stakeholders.
• Support benefits administration activities such as enrollments, changes, and employee inquiries.
• Build, document, and maintain scalable onboarding workflows for international employees as we expand into new countries and entities.
• Partner with external vendors and internal teams to support compliant and consistent international employment processes.
• Administer monthly employee surveys and support operational follow-up and coordination.
• Develop, document, and maintain clear Standard Operating Procedures (SOPs) for core People Operations processes.
• Own and maintain People Operations documentation in Confluence.
• Use sound judgment and modern tools, including AI-powered productivity tools, to simplify workflows and improve efficiency.

Skills and Qualifications:

• 5+ years of experience in HR, People Operations, or HR Generalist roles.
• Strong working knowledge of core HR principles, including confidentiality, data privacy, and compliance.
• Hands-on experience supporting onboarding, job changes, leaves of absence, and terminations.
• Familiarity with U.S. employment compliance and reporting requirements (e.g., EEO-1, ACA).
• Experience supporting benefits, compensation, and payroll operations.
• Strong organizational skills and attention to detail.
• Experience working with HRIS platforms (e.g., Workday, Deel).
• Strong written communication skills.
• Experience using Confluence and AI-enabled productivity tools.
