Staff iOS Engineer (BFF)

Bumble is the Love Company, and our mission is to create a world where all relationships are healthy and equitable, through Kind Connections. As a Staff Engineer on the iOS team for BFF and Plans, you’ll help shape the technology behind products that spark real-life friendship, belonging, and community, helping people move from online connection to meaningful experiences offline. You’ll work across product, design, data, backend, and mobile engineering to reimagine how iOS experiences can make it easier, safer, and more joyful for people to find friends, discover plans, and build community in their everyday lives. This role is for someone who brings deep technical judgment, lives our values of Curiosity and Excellence in how they solve ambiguous problems, and is open to using AI-assisted engineering practices thoughtfully where they can improve quality, learning, or developer productivity without replacing human care and accountability.

Set technical direction for complex iOS initiatives across Bumble For Friends and Plans, translating product ambition into scalable mobile architecture that supports friendship, group, and community experiences.

Lead the design and delivery of high-quality iOS features end-to-end, from technical design and implementation through testing, release readiness, App Store delivery, and post-launch learning.

Champion Excellence by evolving Swift-based architecture in a large production codebase, including patterns such as MVVM, The Composable Architecture-inspired approaches, or similar, so teams can move quickly without compromising maintainability.

Shape performant, accessible, and localised user experiences using deep knowledge of UIKit, working knowledge of SwiftUI, Swift Concurrency, view rendering, app lifecycle, memory management, and iOS platform fundamentals.

Take ownership of reliability and performance across the iOS experience, including multithreading, networked application programming interface integrations, error handling, latency, crash diagnosis, and smooth rendering.

Collaborate with purpose across mobile, backend, product, design, data, and safety partners to define pragmatic technical paths, resolve trade-offs, and see work through from insight to impact.

Mentor engineers through design reviews, code reviews, architecture discussions, debugging practices, and testing strategy, creating a culture of Respect where strong technical debate leads to better outcomes.

Stay curious about responsible AI-assisted development workflows, such as improving test coverage, documentation, debugging, and delivery quality, while applying human judgment, privacy awareness, and care to how tools are used

Typically requires 10+ years of experience, though we welcome candidates with alternative backgrounds that demonstrate equivalent skills.

You have built and shipped production iOS applications at scale, with strong proficiency in Swift, deep experience in UIKit, and working knowledge of SwiftUI in production environments.

You have designed, evolved, and maintained scalable iOS architectures in large codebases, and you can explain trade-offs clearly across MVVM, The Composable Architecture-inspired patterns, modularisation, dependency management, or similar approaches.

You bring strong iOS concurrency and performance expertise, memory management, rendering performance, startup time, network latency, and crash or regression analysis using Xcode debugging tools and Instruments. [Suggested]

You have strong experience with Combine framework and Swift Concurrency - comfortable with reactive data-flow patterns, async/await, actors and structured concurrency, error handling and interoperability with SwiftUI and the Observation framework.

You understand how to integrate and consume networked APIs from iOS clients, including resilient error handling, performance considerations, offline or degraded states, and thoughtful user experience when systems fail.

You have strong knowledge of iOS platform fundamentals, including app lifecycle, view rendering, accessibility, localisation, testing, release quality, and App Store delivery.

You have experience with CI/CD pipelines (CircleCI, Github Actions) to maintain workflow configurations, managing builds, test, and release automation.

You take ownership of complex technical problems, collaborate with purpose across disciplines, and demonstrate an agile mindset when balancing product impact, engineering quality, speed, and long-term maintainability.

You model Bumble’s values of Courage, Respect, and Curiosity by mentoring others, welcoming different perspectives, raising quality standards, and staying open and excited about AI as a helpful engineering partner where it responsibly improves how teams learn, build, and deliver.
