IOS Lead Engineer

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

• Strong hands-on experience with SwiftUI, UIKit and modernizing large scale apps.
• Solid understanding of Swift concurrency, including async/await, structured concurrency, task cancellation, actors, and data-race prevention
• Experience working on large-scale modular iOS applications, with strong judgment around module boundaries, dependency direction, ownership, and API design between modules
• Experience building or scaling a design system / component library used by multiple teams
• Ability to lead architecture and technical decision-making inside a product domain, balancing delivery speed, maintainability, and long-term platform health
• Experience improving engineering quality and developer productivity, including CI/CD, testing strategy, build times, flaky test reduction, and reliable feedback loops
• Ability to collaborate with Staff Engineers, EMs, PMs, Designers, Android/Web engineers, and Security teams on cross-functional technical initiatives
• Experience mentoring engineers and raising the technical bar through code reviews, RFCs/ADRs, technical guidance, and knowledge sharing
• You communicate clearly in spoken and written English

• The opportunity to benefit from our share options programme
• 25 working days of holiday
• Access to all the tools & tech needed for work
• Home office support: we provide IT workstation equipment and a personal budget of up to 540 for home workplace furniture
• Private health insurance
• Mental and emotional health support through the Mindletic app
• Frequent team-building events
• A personal monthly budget for shopping on Vinted
• The opportunity to spend up to 90 days per year - 21 of which can be spent working outside of the EU - on workation
• A dog-friendly office
• In Vilnius office: Gym & in-house meals at friendly prices
• In Kaunas office: a monthly lunch allowance, and a once-a-week provided in-house lunch and breakfast
