At Smile.io, we help brands build loyalty programs that turn customers into lifelong fans. Behind that mission is a growing ecosystem of developers, agencies, and partners building on top of Smile — and the Solutions Squad exists to make that experience exceptional.

About the Solutions Squad
Our vision is simple:

We’re a fully remote team of two, both based in Vancouver, BC, working with a high degree of ownership and trust. We value autonomy, pragmatic decision-making, and moving fast without cutting corners that matter. We use modern AI tools to improve developer productivity, code quality, and product outcomes, and are passionate about intentionally experimenting with how AI can reshape the future of software development.
