Equity offered as a variable dependent on base salary.

We're hiring a Senior UI Developer to report to the Head of Design and lead the evolution of our design language and design systems. We need someone who can design modern UI/UX patterns and implement them directly into our codebase—ensuring every team uses the same components, patterns, tokens, and libraries.

You'll live at the intersection of design and development, shaping the platform-wide systems that power Spare's transportation solutions. While most of your time will focus on platform-wide design systems and technical implementation, you'll also tackle specific user-facing design challenges that benefit from the design-to-code approach.

You'll be instrumental in enabling our team to use AI-assisted prototyping tools to build concepts directly within our design systems and codebase, making it seamless for designers to go from idea to working prototype.

You'll also help upskill our design team on coding concepts, prototyping workflows, and the technical thinking that's becoming essential for modern product design.

This role follows a hybrid schedule: 3 days in-office in downtown Vancouver (Mon/Wed/Fri) with flexibility to work remotely (Tue/Thu), fostering collaboration while providing flexibility.

What You'll Own

Lead the evolution of our design language and systems You'll lead the evolution of our design language into a modern, cohesive system that scales across our entire platform. When you design a new component or pattern, you'll build it directly into our codebase with the right tokens, ensuring global updates and consistency across all teams—eliminating the design-to-dev handoff bottleneck. You'll own design systems, component libraries, and UX patterns that work across multiple product areas.

Enable AI-assisted design workflows You'll build the infrastructure and patterns that allow designers to use AI prototyping tools (like v0, Cursor, Claude) to rapidly create concepts within our existing design language—making it easy for the team to go from idea to working prototype in our actual codebase.

Move from concept to code at startup speed No handoffs, no translation layer—you'll build interactive prototypes that become production features. Your technical skills mean ideas can be tested and validated in real environments, not just static mockups.

Shape the future of product development You'll drive platform decisions that affect how all our products work together. You'll research user needs for both platform-wide patterns and specific product challenges, prototype solutions, and implement them in code—owning the entire journey from problem to solution.

Elevate the team's technical capabilities You'll mentor our design team on coding concepts, technical prototyping, and the evolving skillsets that are becoming essential for modern product design, helping everyone grow their technical skills.

About Spare

Spare's mission is empowering everyone to unlock the potential of mobility.

Spare is the future of shared transportation. We’re revolutionizing how the busy mom from Dallas, the retired teacher from Oslo or the aspiring entrepreneur from Tokyo experiences transportation, by partnering with transportation providers around the world to enable worry-free, efficient, flexible, and automated on-demand solutions.

From the daily commute to non-emergency hospital visits, last-minute lunches, and leisurely trips to the museum, our technology makes people’s lives easier and transit more equitable both for those with specialized mobility needs and those without.

With Spare’s Platform, which includes a feature-rich admin web-panel, as well as rider and driver apps, transportation providers can break free from para and microtransit silos and provide holistic demand-responsive services that give each rider exactly what they need. We also help cities easily optimize their transit network so that the entire transportation ecosystem works better together.

At Spare, nothing is impossible. We think safe, affordable, scalable and eventually autonomous transportation is the right way forward. Join us for the ride!
