We are collaborating with a well‑established consumer marketplace, founded more than a decade ago and currently in a phase of strong international expansion. With millions of active users and a mobile‑first product strategy, the company is heavily investing in technology and growing its engineering teams.

They are now looking for an iOS Engineer who enjoys working on complex mobile products, modern architectures, and high‑impact features in cross‑functional teams.

As an iOS Engineer, you will join one of the key product tribes, contributing directly to the core user journey. You’ll work closely with product managers, designers, and backend engineers to build new features, improve performance, and help evolve a large‑scale, highly modular codebase used by millions of people.

What You’ll Do

• Develop new features in Swift, applying SOLID principles, Clean Architecture, and engineering best practices.

• Work with SwiftUI for new modules and collaborate in the gradual transition from UIKit and RxSwift legacy components.

• Write high‑quality, well‑tested code: unit tests, integration tests, and some snapshot tests.

• Contribute to architectural decisions within your squad.

• Collaborate closely with Product and Design in an Agile, mobile‑first environment.

• Participate in refactoring efforts and continuous improvement of code quality and maintainability.

Tech Environment

• Swift + SwiftUI

• TCA (The Composable Architecture) – nice to have, not required

• UIKit (legacy areas)

• RxSwift (legacy modules only)

• Modular architecture, CI/CD pipelines, strong testing culture

• Bazel/Bazel (in gradual adoption)

What We’re Looking For

• 5+ years of experience building iOS applications with Swift.

• Experience with modern architectures: MVVM, MVI, Clean Architecture, TCA or similar.

• Strong background in testing: unit, integration; snapshot testing is a plus.

• Experience or motivation to work with SwiftUI.

• Good understanding of reactive programming (RxSwift) and UIKit fundamentals.

• A highly autonomous engineer: squads typically have one iOS developer per team.

• Experience working on high‑traffic or large‑scale consumer products is highly valued.

• Engineering mindset: quality, maintainability, refactoring, and a user‑centric approach.

What They Offer

• Permanent contract.

• Hybrid model: minimum of 6 days/month onsite (Barcelona).

• Full‑remote during July & August, plus special holiday periods (Christmas / Easter).

• Flexible working hours (core 9:00–17:00).

• 26 vacation days.

• Annual bonus: 5–10% based on company performance.

• 2,000€ annual training budget + 4 training days.

• Free meals when working onsite (via delivery partners).

• Private health insurance + Urban Sports Club membership.

• Multicultural environment with high technical maturity and strong autonomy.
