Full Job Description

📋 Description

• As a Staff iOS Engineer at BeReal, you will play a pivotal role in shaping the technical foundation of one of the world’s most authentic social platforms, directly impacting how millions of users share genuine, unfiltered moments every day. Your leadership will ensure the iOS app remains scalable, performant, and resilient as BeReal scales toward hundreds of millions of users, reinforcing its mission to foster real human connection in an increasingly curated digital landscape.
• You will drive the technical direction of the iOS platform by defining long-term architectural strategies, ensuring scalability, performance, reliability, and maintainability while balancing immediate product needs with sustainable platform health. This includes designing and delivering high-impact features and systems using Swift, SwiftUI, Swift Concurrency, and modern iOS best practices, all while working closely with product, design, data, backend, and Android teams to align cross-functional efforts.
• You will lead engineering excellence across the iOS team by establishing and advocating for best practices in code quality, testing, CI/CD, and development processes, mentoring junior and mid-level engineers through peer programming, knowledge sharing, and technical guidance to elevate the team’s collective capability.
• You will continuously improve the iOS tech stack and tooling, leveraging AI-powered tools to enhance productivity and creativity, while evaluating the technical, user, and business impact of shipped features through data from Amplitude, Tableau, and user feedback to inform decisions.
• You will work within a mission-driven, international team of 100+ at BeReal, backed by Voodoo’s resources and global scale, where authenticity is not just a feature but a core value — giving you the rare opportunity to build technology that encourages real-life connection over performance.
• In this role, you will deepen your expertise in platform-level iOS engineering, gain influence over architectural decisions affecting a top-tier social app, and grow as a technical leader by shaping team practices, mentoring talent, and driving impact that extends beyond individual features to the long-term health and evolution of the product.

🎯 Requirements

• 8+ years of professional iOS development experience, including ownership of large-scale, consumer-facing applications with significant user bases.
• Proven experience as a Staff iOS Engineer or equivalent, with demonstrated impact beyond feature delivery — such as improving architecture, performance, tooling, or team processes at scale.
• Expert-level proficiency in Swift and SwiftUI, with real-world experience shipping and maintaining production systems using Swift Concurrency, Combine, SPM, and MVVM architecture.
• Strong product sensitivity combined with deep technical expertise, enabling you to make platform-level decisions that balance user experience, business goals, and long-term technical health.
• Track record of mentoring engineers, leading peer programming initiatives, and enabling teams to adopt better technical practices through influence and collaboration.
• Ability to identify, investigate, and drive solutions to complex technical problems that affect multiple teams, using data-informed reasoning and cross-functional communication.

🏖️ Benefits

• Competitive salary commensurate with experience and impact.
• Swile Lunch voucher to support daily meals.
• Gymlib membership fully covered by Voodoo for fitness and wellness access.
• Premium healthcare coverage via SideCare, 100% funded by Voodoo for you and your family.
• Wellness activities hosted in the Paris office to support mental and physical well-being.
• Annual €1,000 budget for attending tech conferences, workshops, and professional development events.
