About the company

A backed consumer startup building a new category between social video and gaming: a mobile app with a feed of playable games that anyone can make from a single text prompt. Users scroll an endless feed of games, play them instantly and create their own. The product is live on the App Store and growing fast. This role sits in our Sofia office, working closely with our London team.

The role

This is a hands-on iOS engineering role, with no management responsibilities. You'll build and ship features in our native iOS app alongside our existing iOS engineer, working closely with Android, backend (Go), product and design.

You'll report to our senior iOS engineer, with some day-to-day oversight from the project manager. It's an early, high-impact role on a fast-growing consumer product.

What you'll do

Build new features in the iOS app, from onboarding to the feed to game creation
Keep scrolling, game loading and playback fast and stable
Work with the Android engineer so features ship on both platforms
Integrate analytics and support A/B testing
Handle App Store releases and compliance updates

What we're looking for

3-5 years of professional iOS development
Strong Swift, with experience in SwiftUI and/or UIKit
Apps you've shipped and maintained in the App Store
A solid grasp of performance, memory and networking on iOS
Comfortable in a fast-moving startup with a small team
Good English for working with the London team
Based in Sofia, or able to relocate within about a month. The role is on-site.
EU citizenship or an existing Bulgarian / Schengen visa. We're unable to sponsor visas.

Big plus

Experience on a consumer (B2C) app, ideally one close to ours: short-form video or social feeds, games, or creator tools
Experience with WKWebView, or embedding web content and games in native apps
Experience with analytics / attribution SDKs (e.g. Singular) and A/B testing
Startup background. An iGaming or betting background is welcome too.

Process

Three steps:

Intro call with our senior iOS engineer
Technical interview with our iOS engineer
Final round with leadership: offer discussion, with an optional office visit

Location: on-site at our Sofia office, with 2 remote days per month
