Help shape a near five-star travel app, and keep raising the bar

At Sunweb Group, our iOS app helps customers search, book and manage their holidays with confidence. As our Senior iOS Engineer, you will own features from the first Figma conversation through development, release and production monitoring.

You will join a well-maintained product that has evolved for more than a decade. Your challenge is to modernise it carefully—without losing the stability and quality our customers value.

Location: Girona preferred / Rotterdam possible

Way of working: Adaptable hybrid

Contract: Full-time

Team: Team Cuba – Mobile

Your impact

• Build and evolve customer-facing iOS experiences using Swift and SwiftUI.
• Work confidently with UIKit where the existing product requires it.
• Own features end to end: refinement, implementation, testing, release, monitoring and continuous improvement.
• Act as a technical reference for iOS through code reviews, architectural decisions and documentation.




• Coordinate with Android and backend engineers so features deliver a consistent experience across both platforms.
• Improve release automation and engineering feedback loops using GitHub, Fastlane, TestFlight, Firebase and New Relic.
• Contribute to API design and integrate services such as payments, excursions and transfers.
• Use modern and agentic coding tools pragmatically to improve productivity and code quality.

What about the team?

You will join Team Cuba, our mobile team. The team is growing to two iOS engineers, two Android engineers, one backend engineer, a Product Owner and an Engineering Lead.

Most engineers are based in Girona, while the Product Owner works from Rotterdam. We work flexibly and rely on clear, proactive and deliberate communication.

You will be our second iOS engineer—not a junior pair. We are looking for someone who can take independent ownership from day one and become a true technical peer to our current iOS engineer.
