[LTA-TRO] SENIOR/ EXECUTIVE UX/UI ENGINEER, TRAFFIC & ROAD IT

[What you will be working on]

We are looking for a UX/UI Engineer to own, design, and scale the user experience powering our next-generation applications and digital services. In this role, you will bridge hands‑on interface design with a deep understanding of user needs, working across agile squads to champion UX/UI best practices and ensure consistent, accessible, and intuitive product experiences.

You will drive the entire design lifecycle — from conducting upfront user research and aligning design specifications with stakeholders, to building robust prototypes and maintaining post-launch design quality. Beyond crafting visually compelling interfaces, you will ensure long-term design excellence by embedding rigorous usability testing, resolving experience gaps identified through user feedback, and maintaining comprehensive design documentation such as design systems, component libraries, and interaction guidelines.

[What we are looking for]

• Knowledge in Design, Human-Computer Interaction, Interaction Design, Computer Science, or a related field, with at least 3 years of experience in UX/UI design, front-end engineering, or a related discipline.


• The following skills are mandatory: a foundational understanding of UX/UI design principles including user research, information architecture, and interaction design; proficiency in at least one design tool such as Figma or Adobe XD to build interactive prototypes, conduct user flows, and maintain design systems; basic experience conducting usability testing and translating findings into design improvements; and the ability to translate wireframes and high-fidelity mockups into semantic, responsive code using HTML5, CSS3, and JavaScript/TypeScript.


• The following skills are advantageous: familiarity with modern JavaScript frameworks such as React, Vue, or Angular; knowledge of accessibility standards such as WCAG 2.1; familiarity with the Singapore Government Design System (SGDS); exposure to CI/CD practices including SHIP-HATS; and familiarity with Government Digital Service standards and IM8 compliance requirements.


• Strong communication and collaboration skills, with the ability to contribute across the full product lifecycle from user research and accessibility audits to post-launch design iteration and front-end tracking, and a proactive and user-centric approach to problem-solving with a strong sense of ownership over interface quality and design consistency.

As part of the shortlisting process for the role, you may be required to complete a medical declaration and / or undergo further assessment.
