Software Engineer II, iOS

Job description

Our Mission As humans, there are few things more exciting than meeting someone new. At Tinder, we’re inspired by the challenge of keeping the magic of human connection alive. With tens of millions of users, hundreds of millions of downloads, 2+ billion swipes per day, 20+ million matches per day, and a presence in 190+ countries, our reach is expansive—and rapidly growing. We work together to solve complex problems. Behind the simplicity of every match, we think deeply about human relationships, behavioral science, network economics, AI and ML, online and real-world safety, cultural nuances, loneliness, love, sex, and more. Our Values Take the Lead: We don't ghost our work or each other. Just as users don't leave their matches hanging, we don't let each other down. Move Fast: We have a bias for action and urgency. Something that could be done tomorrow would be better if done today. Better Together: We keep connection at the heart of dating and at the heart of how we work. Just as our users are better when they connect with others, so are we when we collaborate. Real Talk: We say the hard thing the human way. Just as we ask our users to behave with kindness and candor in our community, we expect Team Tinder to do the same. Safety First: We act with integrity, transparency, and consistency so people feel safe—whether they're swiping, matching, or working alongside us. Spark Fun: We have fun to unlock creativity, fuel innovation, and help us build better experiences for daters. In this role, you will: Contribute to the architecture, design, and implementation of consumer-facing recommendation features in the Tinder iOS app. Build polished, intuitive experiences that connect recommendation logic, APIs, experiments, analytics, and quality validation for millions of members worldwide. Own well-scoped features and components from planning and implementation through testing, experiment launch, and validation, with increasing independence. Collaborate closely with iOS and backend engineers, Product, Design, Data Science and Analytics, QA, ML, Infrastructure, and partner teams across Tinder. Write maintainable, well-tested Swift code and help protect app health, performance, reliability, and member experience. Investigate bugs and quality issues using a structured approach, identify root causes, and add appropriate tests or monitoring to reduce regression risk. Contribute to shared frameworks, technical improvements, code reviews, and engineering practices that make the team more effective. Communicate progress, risks, dependencies, and technical tradeoffs clearly and proactively. Develop expertise in Tinder’s iOS architecture and recommendation systems while progressing toward broader, end-to-end project ownership. Use AI-assisted development tools effectively and responsibly to improve prototyping, implementation, testing, delivery speed, and quality. You'll need: Approximately 2+ years of professional experience building and shipping production, consumer-facing applications with native iOS technologies. Proficiency in Swift and modern iOS development, including SwiftUI and Swift Concurrency. Experience using Xcode and the iOS SDK throughout the application-development lifecycle. Experience consuming REST APIs and integrating mobile features with backend services. Experience with Git and collaborative development workflows such as pull requests and code reviews. Ability to write testable, maintainable code using Swift Testing, XCTest, or similar tools. Solid debugging and code-quality fundamentals, including the ability to give and receive actionable code-review feedback. Clear, solution-oriented communication and a willingness to learn and collaborate in a cross-functional environment. An ownership mindset with the ability to deliver well-scoped work, surface risks, and follow through from implementation to launch validation. Nice to have: Experience with UIKit, Objective-C, or Combine in an existing production codebase. Familiarity with modular iOS architectures or dependency-injection approaches, including MDI, MDUI, Nodes, or Needle. Experience with Bazel, Swift Package Manager, XCUITest, CI/CD pipelines, or mobile monitoring tools. Experience with experimentation platforms, product analytics, design systems, or feature-flagged releases. Experience building recommendation, discovery, personalization, social, messaging, marketplace, or other feature-rich consumer experiences at scale. Familiarity with AI-assisted development tools and responsible practices for validating generated or unfamiliar code and protecting sensitive information. A BS or MS in Computer Science, Engineering, or a related discipline is welcome but not required; demonstrated proficiency in modern iOS technologies and principles matters most.
