Full Stack Mobile Software Engineer - VAZA (Consumer Platform) VAZA is a Toronto-based consumer startup building the world's first monetized opinion market. We turn sports, entertainment, and culture debates into interactive, community-driven markets where users can vote for free or back their vote with money (capped at $100), with winners paid out from the losing side through our proprietary algorithm. In our first 7 months live, we grew to 280,000+ users and processed over $10M in volume - entirely organically, driven by 50M+ social views.

We're building the infrastructure that turns cultural attention into measurable, monetized engagement. We're looking for a Full Stack Mobile Software Engineer to build and scale VAZA's native iOS and Android apps. You'll work directly with the founding team to ship new features, sharpen performance, and deliver the smooth, animation-rich experience our users expect - on a live product where the code you ship is in front of hundreds of thousands of people the same week.

Mobile is your home base, but VAZA is a small team and crossover is expected: you'll regularly work alongside our backend (Rust), web, DevOps, and data teams - whether that's extending an API endpoint your feature needs, tuning a query, wiring up CI, or digging into analytics to understand how users actually behave. Buildand ship features across our native iOS and Android applications. Deliver polished, high-performance UI with complex animation and real-time data.

Maintain and scale a live consumer app serving a rapid-growing global user base. Crossover with the backend team on API design, WebSocket streams, and performance work. Crossover with DevOps on CI/CD pipelines, automated testing, and release workflows.





Crossover with the data team on analytics instrumentation and product insights. Monitor app health and help resolve production issues. Help keep the apps secure, reliable, and fast under load. Collaborate closely with the executives on product direction and the technical roadmap.

URL Session with async/await, WebSockets for real-time market data.
