Full Stack Mobile Software Engineer — VAZA (Consumer Platform)

? **ABOUT VAZA

VAZA isa

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.

Instead o f opinions disappearing into comment sections, VAZA measures collective conviction and settles debates through consensus. 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.

? **ABOUT THE ROLE

We're loo king 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 i s 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. It's an ideal role for an engineer who wants real ownership, moves quickly, and grows with the company.
