Weekend Shopify Developer Jobs in Toronto, ON (NOW HIRING)

You thrive in a team environment, contributing positively through PR reviews, constructive feedback, and collaborative problem solving.

You have a proven ability to work independently while collaborating effectively across teams.

You care deeply about the quality of your work and the experience customers have on the site.

You take ownership of your work without ego- you're open to feedback, quick to help, and willing to learn from mistakes.

You care not only about the health of the website, but also about the health of the team and how you show up as a collaborator.

You are passionate about software development and technology, and you're always asking "Why not?" when presented with a challenging problem.

You're comfortable navigating ambiguity and collaborating with others to find the right solution, even when requirements evolve.

You communicate clearly and thoughtfully, whether you're leaving a PR comment, explaining a tradeoff, or partnering with non-technical teammates.

You want to work somewhere that welcomes everyone - not just tech-folk.

Review business requirements to determine the best design for quality, performant, and scalable web experiences.

Attend regular company meetings to ensure alignment on daily, weekly and monthly objectives.

Proven ability to own features end-to-end, from development through QA, release, and post-deployment monitoring, including accountability for bugs and driving improvements to prevent recurrence.

Experience adapting to Shopify platform changes, deprecations, and new Editions features in production environments.
