Greenhouse is looking for a Senior People Operations Specialist to join our team!

The Senior People Operations Specialist is a key member of our People team, responsible for delivering smooth, compliant, and scalable HR operations across the full employee lifecycle. You’ll be the go-to expert for complex casework, HRIS data integrity, and process design, helping us elevate People Operations from great day-to-day execution to a more automated, insights-driven, shared-services model.

Reporting into our People Operations leadership, you’ll partner closely with People Business Partners, Payroll, Legal, Finance, IT, and key vendors to ensure our processes are accurate, efficient, and employee-centric. This role is ideal for someone who thrives at the intersection of HR operations, systems, and continuous improvement, and who’s excited about thoughtfully using AI and automation to make work better for employees and the People team.

Who will love this job A systems thinker – you naturally see how policies, workflows, and tools connect, and you enjoy untangling complexity to build processes that actually work for people.

A trusted operator – you sweat the details, protect data integrity, and know how to handle sensitive information and nuanced situations with care and good judgment.

A process improver – you’re energized by finding root causes, documenting clear solutions, and turning messy, manual workflows into smooth, scalable ones.

An AI-curious optimizer – you’re comfortable experimenting with new tools, using AI to speed up repeatable work while knowing when human insight matters most.

What you’ll do

Architect Scalable Systems: Drive system design, project execution, and process mapping to identify automation opportunities and deploy AI-enabled tools that align with global best practices.

Adopt AI: Act as liaison to the HR AI Lead, translating high-level AI ambitions into functional People Ops prototypes. While the AI Lead drives the "how" of technology adoption, you define the "what" by ensuring AI applications are grounded in HR compliance and lifecycle integrity.

Resolve Complex Escalations: Serve as the primary expert for Tier 2 and Tier 3 exception cases, applying regulatory and employment law knowledge to provide compliant, nuanced resolutions for a global workforce.

Govern Contingent Workforce: Own the end-to-end lifecycle and compliance for the flexible workforce, partnering with Legal to mitigate co-employment risks.

Drive Data Integrity: Lead comprehensive HRIS audits, utilizing HR knowledge to remediate gaps and design robust governance controls.

Engineer Knowledge Frameworks: Design and maintain SOPs and runbooks that translate complex procedural scenarios into scalable content for the broader team.

Enable Shared Services: Drive the transition to an HR Shared Services model by bridging the gap between technical infrastructure and professional HR service delivery.

Customer Journey & Service Delivery: Deliver accurate and empathetic support to managers and employees on complex scenarios, ensuring a high-quality customer experience that directly contributes to a positive and engaged workforce.

Define Metrics: Collaborate with the HR AI Lead to establish baseline performance metrics, utilizing data driven insights to measure the cost savings and efficiency gains realized through AI enhanced workflows.

You should have

3-5 years of hands-on HR/People Operations experience supporting the full employee lifecycle in a fast-paced environment.

Strong working knowledge of HR processes, employment documentation, and core compliance concepts (e.g., audits, data privacy, record keeping).

Experience working with at least one modern HRIS (Workday preferred) and comfort navigating data, workflows, and configuration at a functional level.
