About the Role

Jump Trading Group is seeking an HR Coordinator to join its high-growth team, supporting the US employee experience through Workday operations, onboarding delivery, and HR policy administration, with a focus on data integrity, system sustainability, and process improvement.

  • Manage the employee lifecycle in Workday end to end — onboarding, organizational change requests (transfers, promotions, new organizations and job profiles), employment verifications, and exits — troubleshooting issues and making corrections as needed.
  • Own Workday data integrity for the US population: audit and maintain employee data, monitor integrations and downstream data flows, and identify and resolve discrepancies before they reach payroll, benefits, or reporting.
  • Build and maintain Workday reporting for the HR team and business stakeholders and identify opportunities to automate or simplify recurring manual work.
  • Evaluate the downstream impact of system and process changes before they are made, applying HR domain knowledge in a systems context and designing processes that remain sustainable as the organization scales.
  • Own new hire onboarding delivery for employees and consultants — coordinate day one orientation, deliver new hire orientation and benefits introductions, and support new joiners through Workday onboarding.
  • Maintain regional employee handbooks and HR policy documentation on Confluence, partnering with Legal and the HRBP team on policy requirements, monitoring changes in employment regulation, and proactively recommending policy updates.
  • Support the payroll and benefits teams on recurring cycles — invoice review and approval, benefits data updates, and audits — cross-training to serve as a back-up during peak periods and absences.
  • Creatively problem-solve new workflow procedures, recommend process improvements, and document standard operating procedures so knowledge is retained across the team.
