Lead iOS Engineer
Tech Stack
Job Description, Responsibilities & Requirements
About the Position
We are looking for a Lead iOS Engineer to support a platform-focused team at Bumble, contributing hands-on to iOS implementation while raising the technical bar across architecture, quality practices, and AI-assisted delivery. You will design and maintain MVVM-based iOS architecture, integrate third-party SDKs and cloud-connected platform functionality, and select and implement appropriate testing strategies for the team. The role requires strong ownership in a high-ambiguity environment, turning unclear requirements into clear technical plans with minimal supervision.
Responsibilities
- Design, build, and maintain high-quality iOS platform capabilities that support consumer-facing experiences.
- Design and evolve the iOS architecture using MVVM, modular architecture, and modern engineering best practices.
- Integrate third-party SDKs and platform services into the iOS application.
- Work across networking layers, API integrations, and backend-connected mobile features.
- Support Cloud Code-related implementation and integration needs where applicable.
- Own iOS work end-to-end while providing technical guidance through code reviews, pairing, and architecture discussions.
- Define and implement testing strategies and quality practices that improve release confidence while balancing maintainability and delivery speed.
- Apply AI-assisted engineering practices to improve delivery, code quality, debugging, refactoring, documentation, and tooling while maintaining engineering standards.
- Communicate clearly with stakeholders, surface risks early, and keep progress visible across time zones.
Requirements
- 5+ years of experience as an iOS engineer with strong hands-on Swift/iOS implementation experience.
- Strong hands-on experience with modern Swift Concurrency (async/await, Actors, structured concurrency) in production applications.
- Strong experience building and shipping production iOS applications at scale.
- Strong knowledge of MVVM and modern architectures such as TCA, Clean Architecture, or similar.
- Proven experience leading technical discussions, driving architecture decisions, and influencing engineering best practices across a team.
- Experience integrating third-party SDKs in production mobile applications.
- Strong understanding of networking, API integration, error handling, and mobile-backend interaction patterns.
- Experience with Cloud Code or comparable cloud-connected mobile/platform functionality.
- Strong experience defining testing strategy, selecting testing frameworks and quality practices, and determining appropriate unit, integration, UI, snapshot, contract, or other test coverage.
- Experience using AI-assisted engineering tools to improve implementation, debugging, refactoring, testing, documentation, and development workflows.
- Strong ownership mindset with the ability to operate independently, communicate progress clearly, and proactively surface risks and blockers across time zones.
- Upper-intermediate English level.
Nice to Have
- Experience with modular iOS architecture in large-scale consumer applications.
- Experience defining or improving team-level testing strategy, not just contributing individual tests.
- Experience working on platform teams or shared mobile foundations used by multiple product teams.
- Experience with cloud-connected mobile features, backend-for-frontend patterns, or services that require close mobile/backend coordination.
- Prior experience in high-ambiguity environments where requirements need discovery, validation, and technical shaping before implementation.
- Practical experience using AI tools to improve engineering workflows while preserving code quality, security, and authenticity.
