Senior Full Stack Developer - UI Design Systems


Join our team 

We’re a customer-driven and product-minded team within TELUS, responsible for our company’s digital evolution. 

We’ve built a suite of tools for practitioners with the goal of growing the platform and simplifying the path to production. Our tools are used across Digital, our partners, and greater TELUS. One of these tools is the TELUS Design System.

The TELUS Universal Design System enables our teams to create consistent customer journeys. It is a holistic platform that integrates code, documentation, guidelines, and design management. Serving as a single source for our digital design guidelines, code patterns, and UI elements, it plays a key role in ensuring the teams can build with self-sufficiency, re-use building blocks, and contribute back to the system.

TELUS team includes a passionate group of strategists, UX and visual designers, full-stack developers, content managers, scrum masters, testers, product owners, people experience specialists and other digital experts.
