IOS developer

Onside is building the first alternative iOS app marketplace in the EU — a platform where developers can publish, distribute, and monetize their apps outside the App Store. We’re here to give developers more freedom, better monetization tools, and transparent policies. Think less bureaucracy, more creativity — and a team that actually ships.

Alongside the marketplace, we’re also developing a crypto-based payments app — a non-custodial wallet and card solution for creators and high-risk platforms (think streaming, payouts).

Now we are looking for an experienced IOS developer to join our team! If you love building clean, beautiful, high-performance iOS apps that don’t just sit in the App Store — this is your kind of challenge.

What you’ll be doing:

• Build and ship native iOS app from scratch using Swift / SwiftUI, Combine, and RxSwift.
• Collaborate closely with backend, design, and product teams to bring features from idea to release.
• Ensure top-tier performance, reliability, and smooth UX across devices.
• Participate in architecture decisions, mentor others, and help grow the iOS team.

Tech we use:

Swift, SwiftUI, Combine, RxSwift, REST / GraphQL APIs, GCP integrations, CI/CD pipelines, performance & crash analytics (Sentry, Firebase, etc.)

You’ll fit in if you:

• Have 4+ years of professional iOS experience.
• Can independently own features end-to-end — from architecture to delivery.
• Enjoy solving complex technical challenges in a fast-moving startup environment.
• Ideally have some background in fintech, payments, or crypto.
• Speak good English and Russian.

Why you’ll like it here:

• You’ll build something new and meaningful.
• Small, senior team with real ownership and no corporate layers.
• Fully remote, flexible hours, straightforward communication.
• We move fast and value people who do the same.

If you are passionate about technology and want to be part of a team that is redefining the marketplace experience, we would love to hear from you!
