At Joist, we’re on a mission to make contractors heroes! Joist is already the #1 platform for contractors worldwide, but there’s still work to be done. We have incredible adoption from contractors, top-tier venture partners from Toronto, San Francisco, and Boston, and a gritty team with that truly cares about what they’re working on.

Sound like you?

Passion for mobile You’re up to date on the latest trends in the iOS ecosystem and you consider yourself a thought leader. You know all the release rumours and you sign up for early access for everything Apple announces.

Innovation iOS gives the developer a lot of freedom to create truly unique user experiences. You’re always looking for the next way to push the boundaries of what can be achieved with on mobile devices.

Performance You understand that a hundred milliseconds of delay can be the difference between a delightful and a frustrating user experience. You can dive into the internals of iOS libraries to understand why your code is not running as fast as you expect.

Delivery Focused You love seeing your work pushed to the App Store. You know how to navigate the app submission process, and have run beta test programs before. You strive to submit your next iteration on your app immediately after the previous submission gets approved, all the while never sacrificing quality.

Teamwork Many of the problems we encounter require insight from many parts of the business. Your ability to coordinate and communicate is essential to our success.
