What You’ll Do

We’re looking for a People Operations Specialist located in the Chicago or San Francisco Bay Area who thrives in a fast-paced environment and is passionate about delivering an exceptional employee experience. In this role you’ll own end-to-end Onboarding & Offboarding programs, support our compliance efforts, and provide broad employee support across HR systems, benefits, and general People operations.

You’ll work closely with the People team to ensure smooth day-to-day operations and help us build scalable processes that support our growing global team. The ideal candidate is a proactive problem-solver who is always thinking about a better way of doing things. You have strong communication skills, are extremely organized, are resourceful and can navigate new or unique situations with confidence.

Onboarding, Offboarding & Compliance:

• Own and continuously improve our New Hire Onboarding Program ensuring a consistent, engaging, and highly impactful experience for all new hires.

• Partner cross-functionally with IT, Facilities, and Hiring Managers to deliver seamless onboarding logistics, including equipment, systems access, and team integration.

• Partner with learning and development to create engaging and impactful onboarding content and programming, including presentations, onboarding documentation, and feedback loops to drive program improvements.

• Manage background checks, employment eligibility (I-9), and required documentation in our HRIS with accuracy and compliance.

• Own the end-to-end Offboarding process — coordinating with IT, Payroll, and other stakeholders to ensure a smooth transition for departing employees.

• Administer compliance related employee training programs in our Learning Management System (LMS) – EasyLlama — including scheduling, creating learning journeys, and completion tracking/reporting.

• Drive program management for the HR compliance portfolio conducting regular audits to support annual EEOC reporting, SOC II, CES, and other customer, state or regulatory requirements.

Employee Support & Operations:

• Own the HR Service Desk and our HR AI bot — answering what comes in, identifying patterns, and improving the bot so it handles more over time and frees the team to focus on employee interactions that require a human touch.

• Maintain and update employee records and HRIS (Rippling) workflow automations and report management.

• Respond to unemployment claims and employment verification requests in a timely manner.

• Proactively identify process gaps, suggest scalable solutions, and collaborate on People Ops projects and other duties as assigned.

What You’ll Bring

• 2+ years of experience in People Operations, HR Generalist, Recruiting Operations, or Benefits Coordinator roles, ideally in a startup or fast-growing environment.

• Hands-on experience with HR systems such as Rippling, Lattice, Ashby (ATS), Checkr, EasyLlama, Confluence, or similar tools.

• Proactive, self-starter mentality. You love finding answers and solving problems before they surface with proven ability to prioritize effectively in a fast paced environment.

• Strong written and verbal communication skills with ability to adapt to a variety of audiences.

• Excellent organizational skills and attention to detail.

• Ability to handle confidential information with discretion and professionalism.

• A willingness to roll up your sleeves and lean in wherever needed. This is a broad generalist role, and we value teammates who see a gap and close it without waiting to be asked.

What Sets You Apart?

• Experience supporting remote and globally distributed teams building scalable People programs that foster connection, engagement, and a positive employee experience across time zones.

• You’ve built something cool with AI or automation — whether that’s a workflow that saves your time each week, an AI-powered onboarding tool, or a script that eliminated a manual process entirely. You’re not just curious about the future of People Ops, you’re excited to shape it.
