[Hiring] Senior Full Stack Engineer @Moongate Studios, Inc.

Role Description

You'll be our third engineering hire, and our first web specialist. Moongate is primarily an iOS app today, with supporting web technology. Our team leans heavily iOS focused, and that's where our engineering depth is. The web checkout, backend, and marketing infrastructure have been built along the way to support the app. They work well, but they've never had a dedicated owner. You'll be the first, working directly with the engineer founders to become the primary contributor to the Moongate web stack and set the standard for how we build everything outside iOS. This is a senior role that, with excellent performance, stands to lead our web engineering as that team grows.

What You'll Tackle:

• Phase 1: Level up our web infrastructure. Take ownership of our web platforms and turn them into systems built for scale: reliable, well-tested, and easy to extend. Build the features that unlock new monetization and acquisition channels and help us grow. Own our web2app and attribution infrastructure.
• Phase 2: Take Moongate to web (and probably Android). Build the app, likely in a multiplatform web/mobile stack, on top of the checkout and account systems from Phase 1. This is an ambitious project that opens up entirely new markets and marketing channels.

Throughout, you'll report directly to the technical founders and work closely with other talented people across marketing, design, and engineering.

• Worked on subscription apps and familiar with terms like "RevenueCat", "paywall test", and "MMP".
• Launched your own app, product, or other project.
• Some design sense and comfortable making calls when specs aren't fully complete.

Benefits
