iOS Engineer

We are looking for a hands-on iOS Developer to join a funded consumer startup in Sofia. It is building a new kind of app that sits between social video and gaming. The product is already live on the App Store, and you will build and ship features for real users from day one. You will work on a TikTok-style endless feed of mini-games made by users, where performance, smooth scrolling and fast iteration really matter. The role covers the whole feature cycle: quick prototypes, A/B tests, App Store releases and tracking results in mobile analytics. You will work closely with a senior iOS engineer and the leadership team in a small, fast-moving team where your work is seen right away. We want someone who takes ownership, enjoys working on-site with the team and likes to ship often.

Details:

• Schedule: Full time
• Location: Onsite – Sofia, Bulgaria (if you don't live there yet, you need to move to Sofia within about 1 month)
• Start: ASAP
• Duration: Long-term
• English: Fluent
• Type of collaboration: Internal Employment (full-time employment contract; B2B is not possible)

About the project:
The company is a funded consumer startup creating a new category between social video and gaming. Its app has an endless, TikTok-style feed of short mini-games made by users, which people can play, share and create. The product is live on the App Store, and the team is hiring more engineers for its Sofia office. The company works like a typical startup: it prototypes fast, releases often and makes decisions based on experiments and data. Engineers own their features and work directly with product and leadership. It is a great place for someone who wants to shape a fast-growing B2C product that real players use every day.

You have:

• 5+ years of professional iOS development experience
• A track record of shipping production iOS apps to the App Store
• Strong Swift skills and hands-on experience with SwiftUI and UIKit
• Experience with WKWebView and showing web content inside native apps
• Experience with App Store releases, A/B testing and mobile analytics
• Ability to work in a fast-paced startup with quick prototypes and tight deadlines
• An entrepreneurial mindset and a habit of taking ownership
• Fluent English
• EU citizenship or a current Bulgarian/Schengen visa (visa sponsorship is not available)
• You live in Sofia or can move there within about 1 month, and you are ready to work fully on-site

Nice to have:

• Experience building B2C consumer apps
• Experience at early-stage startups
• Experience in iGaming, betting or mobile gaming (including hyper-casual games)
• Experience with social, video or feed-based apps

What to do:

• Build, ship and maintain features for a live consumer iOS app using Swift, SwiftUI and UIKit
• Build and improve the endless mini-game feed, with a focus on performance and a smooth user experience
• Integrate and optimize web-based game content inside the app using WKWebView
• Prototype new ideas quickly and turn the ones that work into production features
• Set up and run A/B tests, and use mobile analytics to measure how features perform
• Own the App Store release process together with the team
• Work closely with the senior iOS engineer, product and leadership on priorities and technical decisions
• Do code reviews and help keep code quality high as the product grows

Interview process:

1. Intro call with the senior iOS engineer
2. Technical interview with the iOS engineer
3. Final round with leadership to discuss the offer (with an optional office visit)
