THE CHALLENGE ?

You will join the iOS Platform team, the team that sets the technical direction
for iOS at Wallapop. Our users are primarily other engineers, and our mission is
to supercharge their daily productivity while defending the quality and
performance of our app. We own the build system, developer tooling, module
architecture, testing infrastructure, and observability foundations that
everyone else ships on top of.





We work on a 10+ year-old codebase used by millions of people (~115 modules and
over 20,000 Swift files), where every second shaved off a build is multiplied
across the entire engineering chapter.

In this role, you will own app performance as a product metric—from launch time
and responsiveness to memory footprint and app size. As an iOS Platform
Engineer, you will have company-wide scope, acting as an architect, mentoring
engineers across the chapter, and tackling our most complex technical
challenges.

OUR TECH STACK:

* Build & Infra: Bazel-based build system with remote caching/execution, paired
with Tente (our in-house Go CLI and BSP server to support IDEs like VSCode,
Neovim).
* CI/CD & Testing: High-scale pipelines on Bitrise, a robust testing pyramid
featuring Quick/Nimble, ~9,000 snapshot references, and Maestro E2E flows in
the cloud.
* Architecture & UI: Simplified, TCA-inspired architecture built on RxSwift,
custom de
