About Triumph

Triumph makes mobile gaming more thrilling by letting players wager and win cash. We have the top app in the Casino category on the App Store, and are hyper scaling with a team of under 30 people, achieving 50% month over month growth at a nine figure yearly revenue run rate. We're innovating in the space with genuinely new product offerings - for example, we're the only real money player to offer live mass multiplayer games, and are primed to scale worldwide. We just launched a new product in the collectible space, which, one month after launch, is already at an eight figure yearly revenue run rate.

Triumph is backed by some of the top consumer VCs including Goodwater Capital, General Catalyst, and DraftKings Drive Fund.

• Rapidly building and iterating on new features and enhancements to increase engagement and LTV of existing user cohorts.

• Build out features to allow us to scale the app to geographies outside the United States

Why Triumph?

• Small, high-impact engineering team that is scaling up. The core engineering team that built the platform is 4 people! Now that we’re scaling rapidly, we’re building a team that can expand the scope of our products and reach. This means you’ll have opportunity to take leadership and grow as an engineer with the company.

• Passionate team that is proud of our work
