Core Responsibilities

Primary Functions

Conduct in‑depth user research, stakeholder interviews, analytics review and usability testing to uncover user behaviour, pain‑points and opportunities for experience improvement.
Create, iterate and refine user flows, journey maps, wireframes, storyboards and interactive prototypes to validate designs and align with business objectives.
Develop front‑end interfaces that realize design concepts with HTML5, CSS3, JavaScript/TypeScript, responsive layouts and performance‑optimized code.
Collaborate with UX/UI designers and product owners to ensure design consistency, brand alignment and cohesive user experience across products and devices.
Build and maintain reusable UI components, design‑system elements, style guides and libraries to accelerate development and enforce visual consistency.
Implement accessibility standards (WCAG 2.1+, Section 508) and inclusive design practices to ensure all users can access and engage with digital experiences.
Integrate front‑end code with backend services and APIs, ensuring seamless data flow, performance and error‑handling across the user experience.
Monitor user engagement and conversion metrics, analyze heat‑maps, conduct A/B tests, and derive insights to refine user experience and improve key business indicators.
Optimize user interfaces for speed, responsiveness, device compatibility and cross‑browser functionality to maintain high performance and smooth interactions.
Troubleshoot front‑end issues, debug UI defects, address performance bottlenecks, and implement fixes to maintain quality and reliability of the user experience.
Engage in agile software development processes: sprint planning, stand‑ups, retrospectives, backlog refinement and iterative design/development cycles.
Produce and maintain documentation including technical specs, design rationale, prototype libraries, style sheets and test logs for future reference and knowledge sharing.
Mentor junior developers and designers by sharing best practices related to UX, front‑end development, performance optimisation and accessibility.
Participate in or conduct usability studies, heuristic evaluations, and gather qualitative/quantitative feedback to influence design decisions and improve experience outcomes.
Recommend and implement design‑engineering improvements: new tools, workflows, frameworks, component architectures and performance enhancements.
Ensure application design and implementation support SEO best practices, structured markup, semantic HTML and performance considerations for search ranking and discovery.
Contribute to cross‑team initiatives including product strategy, design system governance, brand experience consistency and roadmap planning.
Manage versioning and deployments of front‑end assets, support release planning, QA collaboration, regression testing, and coordinate with DevOps where needed.
Stay current with emerging UX and front‑end development trends, frameworks, frameworks, tools (such as Figma, Sketch, Adobe XD), design systems, and evolving user behaviours.
Align user‑experience deliverables with business metrics and product outcomes: collaborate with stakeholders to define KPIs, validate success criteria and iterate to deliver measurable value.

Secondary Functions

Support ad‑hoc user‑experience tasks such as quick prototype development, micro‑interactions, design tweaks or onboarding flows.
Contribute to the organisation’s UX roadmap and design‑engineering strategy by recommending component reuse, system rationalisation and technical debt reduction.
Collaborate with business units to translate domain or user‑needs into development tasks, user‑stories and backlog items.
Participate in agile ceremonies in the UX/development team and assist in continuous refinement of UX workflows, tooling and metrics.
