SmartHR
SmartHR offers cloud-based human resources and labor management software that has held the No. 1 market share in the labor-management cloud sector for seven consecutive years. It provides solutions not just for streamlining HR and labor operations, but also to support productivity improvements for everyone at work.
Today, SmartHR is positioning itself beyond a typical startup—it is evolving into a scale-up firm that is expanding its scope to become an integrated platform for “human capital management.” While its core still lies in labor management, the product now encompasses recruitment, employment contracts, attendance and payroll, and more advanced functionalities like talent evaluation, placement simulation, and data analytics.
I worked at this company for four years as a designer, where I was responsible for product design as well as maintaining the design system.

As a product designer, I was responsible for defining user stories, crafting UI designs, and maintaining the shared design system. Specifically:
-
User Story Definition & Journey Mapping
Collaborated with product managers and HR stakeholders to identify pain points (e.g. evaluation process bottlenecks, transparency, usability for mobile users) and translated them into user stories and flows. -
UI / Interaction Design
Designed screens and interactions across roles (reviewer, reviewee, admin), including evaluation sheet templates, progress dashboards, feedback mechanisms, and adjustment views (e.g. rating distribution). -
Cross-Functional Iteration
Worked closely with engineers to prototype and validate designs, refining through usability testing and feedback cycles. -
Design System Maintenance
Ensured consistency across modules by updating components (forms, tables, notifications, charts) in the shared design system. This allowed new evaluation features—such as 360° feedback and matrix visualizations—to be adopted smoothly. -
Feature Integration
Collaborated across teams to maintain a coherent UI/UX between the Evaluation module and other talent management features (career records, placement simulation, analytics).
For confidentiality reasons, I can’t share too many specifics — but here’s a summary of the design philosophy and thinking I had at the time.
