Working at the crossroads of technology and human resources, you’ll partner closely with product owners and stakeholders to develop sustainable and high-performing Workday configurations.

This role requires hands-on technical leadership, the ability to influence process evolution, and a strong bias toward digital innovation.

• Acting as a proactive solution owner, delivering configuration aligned with problem definitions and requiring minimal direction.

• Driving continuous process improvement through redesigns and optimized system usage.

• Communicating effectively with stakeholders, product teams, and peers to ensure alignment on timelines and outcomes.

• Collaborating as part of a broader team while functioning fully independently on your assigned deliverables.

• Maintaining a forward-looking approach to digital tooling and exploring opportunities to integrate emerging technologies, including Generative AI capabilities.
