KeepCart is a growing Shopify app company looking for a Senior Shopify App Developer to join the team for the long term.

We are looking for someone senior, reliable, communicative, and highly organized, who can take ownership of their work and contribute thoughtfully to a small team.

The stack is centered around TypeScript, React, Node.js, Gadget.dev, and the Shopify ecosystem. Strong experience building public Shopify apps is essential.

The role will start on a part-time basis, with the intention to ramp up over time into a larger commitment and potentially full-time for the right person.
