ABOUT VAZA

VAZA is a Toronto-based consumer startup building the world's first monetized opinion market. We turn debates across sports, entertainment and culture into interactive, community-driven markets where users can vote for free or back their vote with money, capped at $100 per user per matchup. Winners are paid out from the losing side through our proprietary algorithm.

Instead of opinions disappearing into comment sections, VAZA measures collective conviction and settles debates through consensus. In our first seven months live, we grew to more than 300,000 users and processed over $10 million in volume - entirely organically and driven by more than 50 million social views.

We are building the infrastructure that turns cultural attention into measurable, monetized engagement.

ABOUT THE ROLE

We are looking for a Full Stack Mobile Software Engineer to build and scale VAZA's native iOS and Android applications.

You will work directly with the founding team to ship new features, improve performance and deliver the smooth, animation-rich experience our users expect. You will work on a live consumer platform where the code you ship can be in front of hundreds of thousands of users within the same week.

Mobile will be your primary focus, but VAZA is a small, collaborative team and crossover is expected. You will regularly work alongside our backend, web, DevOps and data teams - whether that involves extending an API endpoint, tuning a query, improving CI/CD or reviewing analytics to understand user behaviour.

This role is ideal for an engineer who wants meaningful ownership, enjoys moving quickly and is excited to grow with an early-stage consumer technology company.

WHAT YOU'LL DO

- Build and ship features across VAZA's native iOS and Android applications.
- Own the mobile release process from development through TestFlight and the Google Play Console.
- Deliver polished, high-performance interfaces with complex animations and real-time data.
- Maintain and scale a live consumer application serving a rapidly growing global user base.
- Collaborate with the backend team on API design, WebSocket streams and performance improvements.
- Collaborate with DevOps on CI/CD pipelines, automated testing and mobile release workflows.
- Work with the data team on analytics instrumentation and product insights.
- Monitor application health and help resolve production issues.
- Support payment flows and integrations with payment providers.
- Help keep the mobile applications secure, reliable and quick under load.
- Work closely with the founding and executive teams on product direction and the technical roadmap.
