Principal UX Architect

About the role

SingPost is looking for a Principal UX Architect, an execution-first system builder who diagnoses and removes root-cause friction across its omni-channel ecosystem: the SingPost Mobile App, web portals, physical Post Offices, kiosks and unmanned Smart Autolobbies. The role works between high-level service blueprints and pixel-level Figma token systems, using Design Thinking and Systems Thinking to balance human desirability with operational viability.

Key responsibilities

• Partner with business unit leaders and executives to distill competing requirements into unified experience strategies, and run alignment workshops, service-mapping sessions and rapid ideation loops
• Translate business models and logistics structures into horizontal experience frameworks and multi-channel navigation charts
• Run hands-on user intercept testing and interviews in live environments, then turn insights into multi-channel user journey blueprints and task flows
• Build low-to-mid-fidelity prototypes to validate usability assumptions with end-users and frontline staff
• Ingest legacy business states and technical analyst input to map logical navigation frameworks
• Turn data and transactional logic into clear screen layouts and wireframes, working with Product Managers and Tech Leads so designs match API capabilities and deployment realities
• Maintain Figma design tokens and absolute-layout component models, hardcoding responsive, multi-breakpoint auto-layout components
• Act as UX quality gatekeeper by auditing staging and UAT builds, and embed analytics tracking events and behavioural hooks into the experience blueprints

Required profile

• Over 5 years of experience in a UX lead role
• Proven ability to simplify complex transactional systems, enterprise supply chain software or high-scale checkout flows into clear navigation matrices
• Track record of running strategic alignment workshops for senior executives and turning complex information into structured visual frameworks
• Hands-on experience with guerrilla user research, user interviews, post-occupancy studies or physical space mapping (retail, logistics kiosks, public terminals)
• Ability to read web analytics, drop-off funnels and heatmaps to prioritise layout improvements
• Experience with AI-driven design and prototyping tools, and basic knowledge of React Native, CSS Flexbox and API payload bindings are advantages

Required skills

• Absolute mastery of Figma, including nested auto-layouts, flexible responsive constraints, interactive prototyping and variable token management
• Design system maintenance and responsive component modelling in Figma
