The Mobile Core squad in Platform Tribe

The Mobile Core team's mission is to improve the mobile developer experience, by providing and delivering high standards, quality, automated processes, and tooling. 

One of our pillars is to build & scale robust App Foundations: foundational architecture, shared frameworks, Core & UI components, providing iOS developer tools. We want to make sure that our app scales, but also that iOS engineers are writing easier and more consistent code.

Our second pillar is to elevate & accelerate our App Infrastructure: develop faster and more reliable CI/CD pipelines, easy release process, better QoS monitoring, and quality & profiling.

We are a remote team from different cultures & backgrounds, spread across France & Germany. We are composed of Senior Engineers on Android & iOS and a Senior Engineering Manager. Other mobile engineers from product squads are also invited to contribute to technical & core projects across squads from time to time.

The role & responsibilities 

We are looking for an iOS Senior I Engineer to contribute to the iOS core foundations, architecture & infrastructure stack. The engineer in this role will produce scalable libraries & frameworks, elevate iOS engineering excellence, and share their knowledge within the iOS Community at Back Market. 

The engineer will also contribute to the mobile engineering chapter, with talented iOS & Android engineers but also with other technical leaders from other platforms (SRE, Backend, Frontend, CyberSec, Data…). Whether hooked on Swift, developing advanced UI with motion, or purely Core architecture, the engineer will work efficiently and contribute to collaborative work by remaining open to new ideas.

- Consistently delivers iOS code that sets the standard for quality and maintainability, making the iOS app scalable & accelerating product iterations

- Effectively contributing to technical initiatives to reach the iOS engineering vision, accountable for large team project features, including ones with external dependencies.

- Ability to design code through technical conception before development, ensuring robust and efficient code patterns (Swift concurrency, thread safety, and race conditions)

- Curiosity and proactiveness in implementing new Swift and iOS technologies: SwiftUI (migration started in 2022), property wrappers, result builders, and functional programming.

- Build & scale our app architecture (MVVM-C or similar architectures), advocate for multi-modules, and dependency injection. Understanding and applying SOLID principles while recognizing the importance of simplicity (KISS).

- Find ways to prevent regressions, push for Unit and UI testing by collaborating with QA & iOS Engineers, exploring new E2E testing practices, from native to third-party solutions.

- Elevate the iOS app performance with strong monitoring practices from App launch to app size, memory usage, and smooth UI performance (Datadog, Crashlytics)

- Improve the release process with an automation mindset & practices for our CI/CD pipelines & workflows (Bitrise CI, Fastlane, Testflight, Firebase App Distribution, GitHub Actions, Renovate, Mergify).

Recruitment process :

- Phone screen with Yann (30 min)

- Technical screening with two iOS engineers (~45 minutes)

- iOS live technical interview exercise & discussion (~1h30)

- Team fit with your future manager + one person from our product/platform engineering team (~1h)

- BM value interview with our leadership (~45m)
