People Technology Platform Engineer (Workday)

Role Overview:

The People Technology Platform Engineer, Workday is responsible for designing, building, and evolving SIE’s global Workday platform across core HR domains.

This role operates as an independent contributor within People Technology Services, owning the design, configuration architecture, and delivery of scalable Workday solutions. The role translates business needs into durable platform capabilities, ensuring solutions are reusable, maintainable, and aligned with long-term system design and governance standards.

Working within an Agile product delivery model, this role contributes to both the continuous evolution of the platform and the reliability of core services. The Platform Engineer partners closely with Product, Data, and Integration teams to deliver cohesive, end-to-end solutions across the People Technology ecosystem.

This role is suited for individuals who combine strong functional understanding with a systems approach, and who are motivated to build, improve, and scale enterprise platforms over time.

What you'll be doing:

Platform Engineering & Solution Design

• Design, configure, and implement scalable Workday platform solutions across core HR domains, including business process frameworks, organizational structures, eligibility rules, and calculated fields
• Define and apply configuration design patterns that promote reuse, scalability, and maintainability across the platform
• Translate business problems into well-structured system solutions, ensuring alignment with platform capabilities, governance standards, and long-term sustainability
• Evaluate solution options and make informed design decisions, balancing business needs, system constraints, and operational considerations
• Own end-to-end delivery of platform changes, including design, build, testing, and deployment readiness
• Ensure solutions are consistent with broader platform architecture and avoid fragmented or one-off implementations

Platform Ownership & Operations

• Act as a platform owner for assigned Workday domains (e.g., Core HCM, Absence, Compensation, Talent), accountable for system behavior, design integrity, and continuous improvement
• Maintain platform reliability through issue diagnosis and resolution, identifying root causes and implementing structural improvements to reduce recurrence
• Partner with team members to prioritize demand, balancing business urgency with platform sustainability and capacity
• Collaborate with multi-functional teams (e.g., integrations, data, security) to deliver cohesive, end-to-end platform solutions

Data & Reporting Solutions

• Design and deliver scalable reporting and data solutions, including Advanced, Matrix, and Composite reports, as part of the broader People data ecosystem
• Develop and maintain calculated fields and data structures to support both operational and analytical use cases
• Ensure accuracy, integrity, and consistency of data across Workday processes and outputs

Delivery & Agile Execution

• Translate business needs into clearly defined user stories and technical solutions
• Participate actively in Agile delivery, including sprint planning, backlog refinement, and retrospectives
• Own and deliver assigned workstreams within sprint cycles, ensuring quality and alignment with expected outcomes
• Implement and support testing activities (unit, integration, UAT), ensuring solutions meet functional and technical expectations

Platform Design & Continuous Improvement

• Find opportunities to improve platform scalability, performance, and maintainability
• Contribute to evolving platform design standards, patterns, and governance practices
• Drive incremental automation and simplification of manual or fragmented processes
• Continuously improve individual capability and contribute to team learning and development

Governance, Compliance & Quality

• Ensure solutions meet data privacy, security, and audit requirements
• Follow established governance, release management, and change control practices
• Contribute to improving documentation, standards, and ways of working across the platform

What we're looking for:

• 5+ years of hands-on experience with enterprise platforms, including direct configuration and delivery of Workday solutions
• Demonstrated experience designing and implementing scalable configuration solutions, including business processes, calculated fields, and core system setup
• Proven track record to independently troubleshoot and resolve system is
