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.

 

We’re looking for a fully remote Senior Software Engineer to join our small, highly autonomous team and help us build a world-class platform for developers integrating with Smile.

 

 

🌍 About the Solutions Squad

Our vision is simple:

We serve app developers, agencies, and internal teams by focusing on outcomes, not just features: clarity over complexity, thoughtful defaults over configuration sprawl, and experiences that feel obvious in hindsight.

 

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.

 

This role is hands-on and impact-driven. Depending on your interests and strengths, you’ll spend time on things like:

- Designing, building, and evolving public APIs used by external developers and partners

- Improving the security, consistency, and usability of Smile’s API surface

- Building and maintaining Ruby on Rails services that power integrations and developer tooling

- Developing and evolving Smile’s JavaScript SDKs and frontend libraries

- Crafting thoughtful developer experiences — from API ergonomics to documentation

- Iterating on existing and building new in-house integrations

- Partnering with internal teams to help solve for novel merchant use cases

 

As someone more senior, you’ll also play a meaningful role in:

- Championing technical discussions, decisions, and trade-offs

- Identifying opportunities to raise the bar in areas like architecture, performance, and security

- Sharing context, feedback, and knowledge within and across teams

 

Our stack today includes Ruby on Rails, JSON APIs, JWTs & OAuth, and modern frontend frameworks like React, TanStack, and Ember.js. We store data in PostgreSQL and use Kafka for system events and messaging.

Our system processes massive amounts of transactions every second, and everything we do is high-volume + built for scale. Since we work in e-commerce, reliability and security are both critical components of everything we ship.

 

Smile is a remote-first company built on trust, ownership, and continuous improvement. We believe great work happens when people feel supported, challenged, and empowered to do their best work.
