IOS Lead Engineer (Vinted, UAB)

Job description:
We're looking for a Lead iOS Engineer to join our Design Systems team. Our mission is to help product teams ship high-quality experiences faster by providing reusable UI solutions and the foundations that make them easy to build with at scale.
We own the shared UI components used across Vinted, but our scope goes well beyond building components. We invest heavily in the processes, tooling, and standards around them: ensuring our design system is AI-native, leading the SwiftUI migration, supporting modern UI patterns, pushing our components toward greater composability and flexibility, and improving how our design assets are maintained and shipped to customers.
On iOS, you'll have real ownership of the technical direction of our design system and help keep it aligned with where the platform is heading. You'll be hands-on — writing code, prototyping patterns, reviewing PRs, and shaping architecture through RFCs and ADRs — while making sure our foundations remain well-architected, well-tested, and easy for product teams to build on. You'll also help us make the design system work effectively with AI, from generating screens using our UI components to providing reliable, well-documented building blocks that AI tools can use correctly. As the senior technical voice for iOS within Design Systems, you'll represent the platform in the Frontend Platform Council, where domain leads align on shared standards.
Be the go-to iOS engineer and technical decision-maker for the Design Systems domain
Own architecture and design decisions for our shared iOS component library and design-system tooling, balancing delivery speed with long-term platform health
Push our components toward greater composability and flexibility, so product teams can build a wider range of screens without forking or patching them
Help make our design system AI-ready — ensuring components, documentation, and patterns are structured so product teams can reliably generate screens with AI tooling
Improve the processes behind how design assets are maintained and shipped, from design handoff to release
Drive module boundaries, dependency direction, and API design for the packages that other iOS teams depend on
Improve engineering quality and developer productivity across the domain: CI/CD, testing strategy, build times, flaky test reduction, and reliable feedback loops
Apply modern Swift concurrency (async/await, structured concurrency, actors, data-race prevention) to keep the codebase safe and maintainable as it scales
Represent iOS in the Frontend Platform Council, helping create alignment and make decisions on shared platform standards across domains
Collaborate closely with Staff Engineers, EMs, PMs, Designers, and Android/Web engineers to keep the design system consistent and useful across platforms
Mentor engineers and raise the technical bar through code reviews, RFCs/ADRs, technical guidance, and knowledge sharing
Requirements:
Strong hands-on experience with SwiftUI,…
