Senior Software Engineer

Role & responsibilities

Role Summary

Senior Software Engineer responsible for building and evolving a React-based common UI component framework that enables consistent, accessible, and scalable front-end experiences across products. This role is UI-focused, driving design-system-led development, reusable components, and enterprise-wide adoption.

Works as a strong individual contributor, delivering high-quality components while influencing engineering teams to adopt standardised UI patterns and practices, contributing to platform-led engineering outcomes.

Roles & Responsibilities

• Design, develop, and maintain reusable, responsive UI components and shared libraries using React.
• Define and evolve a common UI framework / design system aligned with accessibility, performance, and usability standards.
• Drive enterprise-wide adoption of common components through enablement, documentation, and collaboration with product teams.
• Translate ambiguous UI requirements into scalable, reusable component designs and implementation patterns.
• Ensure adherence to coding standards, accessibility (WCAG), and responsive design principles.
• Collaborate with Product, UX, and Engineering teams to ensure consistent user experience across applications.
• Lead and contribute to code reviews, improving overall UI quality and maintainability.
• Identify and eliminate duplication by promoting reuse and platform mindset across teams.
• Build reference implementations and accelerators/templates for faster adoption.
• Proactively identify and resolve UI performance, usability, and consistency gaps.
• Mentor engineers on front-end best practices, component design, and modern UI engineering.
• Contribute to continuous improvement of engineering practices, tooling, and UI standards.

Core Competencies

Platform & Reusability Mindset

• Builds shared UI capabilities that reduce duplication and improve engineering velocity.
• Designs components as scalable assets consumed across multiple teams.

Collaboration & Influence

• Drives alignment across teams on UI standards, patterns, and frameworks.
• Enables adoption through documentation, demos, and mentoring.

Execution & Ownership

• Converts ambiguous requirements into well-defined UI components and libraries.
• Owns quality, maintainability, and usability of the UI platform.

Engineering Craft

• Produces clean, maintainable, and extensible front-end code.
• Sets a high bar for UI quality, review practices, and usability standards.

Continuous Improvement

• Identifies opportunities to simplify UI development and improve developer experience.
• Actively contributes to UI engineering standards and tooling evolution.

Technical Expectations

Core Front-End
