Position overview:

We’re looking for an HR Generalist who thrives in a systems‑driven environment and enjoys balancing people support with data accuracy. You’ll be hands‑on across HR operations, onboarding, HRIS data, payroll inputs, and employee support, while partnering closely with HR, Finance/Payroll, and business leaders.

As the HR Generalist, you will:

• Own day‑to‑day HR administration: contracts/letters, onboarding/offboarding, personnel files, probation tracking, and changes (promotions, transfers, terminations).
• Maintain accurate HRIS employee data, org updates, and documentation with impeccable attention to detail (Oracle HCM.)
• Prepare monthly payroll input files (hires, changes, allowances, time off, terminations) and reconcile against approvals; coordinate with Payroll to resolve discrepancies and support audits. (ADP Celergo.)
• Build and maintain recurring HR dashboards (headcount, attrition, leave, compliance) and ad‑hoc reports using Excel (pivot tables, lookups, basic formulas).
• Spot trends and surface insights to HR/leadership; recommend fixes and process improvements.
• Apply company policies and local practices; escalate issues appropriately.
• Serve as a responsive point of contact for employee questions (benefits, leave, HRIS, payroll status), providing clear, timely guidance.
• Document SOPs; streamline workflows with Finance/Payroll/IT; test HRIS or process changes and help roll out improvements.

Our ideal candidate will have: 

• 2–3 years of HR experience (generalist or HR operations) in a modern ERP/HRIS environment, ideally in a multinational context.
• Hands‑on experience with Oracle HCM (or similar HRIS) and ADP/Celergo payroll coordination.
• Bachelor’s degree in Psychology or Law (or closely related field).
• Fluency in English (written and spoken) with strong, professional communication.
• Excel proficiency (pivot tables, VLOOKUP/XLOOKUP, filters; comfort cleaning and reconciling data).
• Demonstrated learning capacity and curiosity, able to ramp quickly on systems/processes and adopt changes.
• Analytical mindset with high accuracy, structured problem‑solving, and a bias for action.

Nice to have:

• Experience supporting Spanish employment processes and practices.
• Exposure to shared‑services or multi‑country payroll coordination.
• Familiarity with tickets/portals for payroll/HR service requests (e.g., ADP eService).
