Senior Mobile Platform Engineer arbeitnow YAZIO

Yazio is one of the most popular nutrition apps in the world, helping millions of people lead healthier lives through intuitive calorie tracking, thousands of delicious recipes, personalized fasting plans and seamless integration with popular fitness trackers.

We’re looking for a Senior Mobile Platform Engineer (iOS) to join our Mobile Platform Team. If you’re an experienced iOS engineer who wants to enable others by tackling tooling challenges, architectural improvements, optimizing CI/CD pipelines and collaborating across squads—this is your chance to make a big impact.

This is a full-time, 100% remote position. You can be based in Germany, Spain, Portugal or the U.K.

As a Senior Mobile Platform Engineer (iOS), you will:

Drive improvements to our iOS app architecture and development workflows, ensuring scalability and maintainability

Collaborate with mobile feature squads to improve the development experience by creating better tools, automation and shared services. Understand their pain points that translate into our backlog

Support non-feature squad teams (e.g. Marketing, Analytics) on initiatives that drive value to the business and not just the codebase

Use AI as a force multiplier. You won’t be writing every line of code yourself anymore, but you’ll understand and own the outcome

Own and improve our iOS build system, CI/CD pipelines and development tooling

Help ensure key engineering updates, improvements and standards are communicated clearly and consistently across the company

Expand your knowledge and get your hands dirty with Kotlin (Android) and KMP

You have 5+ years of experience as a Mobile Engineer (bonus points if you've worked in a platform team before) or in a similar role within a product-focused engineering organization

You have deep expertise in Swift and the iOS toolchain, including strong knowledge of the Xcode build system and development workflows

You're comfortable with CI/CD tooling, scripting and automation—and you know how to use them to streamline development and deployment

You're an excellent communicator who proactively shares knowledge, fosters alignment across teams and ensures transparency around technical decisions. You’re comfortable working in English, which is our primary language for collaboration

You take full ownership of your work, are highly self-motivated and lead by example in cross-functional collaboration

You’re happy to work beyond traditional iOS boundaries—whether it’s exploring Kotlin Multiplatform, helping Android engineers or supporting QA with automation and tooling

You have a strong quality mindset and are committed to engineering excellence, both in your own work and across the teams you support

Here’s what you’ll be working with:

iOS:
Xcode, Swift, SwiftUI, SPM

Cross-platform:
Kotlin Multiplatform (KMP). Most of our business logic is shared, and we’re continuing to move more towards it
