[Hiring] Staff iOS Engineer @BeReal

Role Description

We are looking for a Staff iOS Camera & Video Engineer to join BeReal and work on one of the most critical parts of our product: the camera experience.

You will build and improve the capture, image, and video pipelines behind BeReal's core flows — including multi-camera capture, instant capture, front/back video composition, and media quality. This is a hands-on role for someone who enjoys working close to Apple's media APIs, solving real-time performance challenges, and delivering a fast, reliable, high-quality experience.

• Design, build, and maintain high-performance camera and video features on iOS.
• Own and improve parts of our AVFoundation camera stack: capture sessions, devices, formats, frame rates, exposure, and device capabilities.
• Build and optimize real-time image and video processing pipelines.
• Improve capture quality, latency, stability, and smoothness across supported iPhone models.
• Work on multi-camera flows, front/back video composition, video encoding, media export, and audio/video synchronization.
• Optimize CPU, GPU, memory, battery usage, thermal behaviour, buffer allocation, and multithreaded processing.
• Investigate device-specific and iOS-version-specific behaviour, and propose pragmatic technical trade-offs.
• Work closely with iOS engineers, product, design, backend, and data teams.
• Contribute directly to the codebase and raise engineering standards around media performance and reliability.

Qualifications

• 6+ years of iOS experience, including strong hands-on work on camera, video, or media-heavy features.
• Deep expertise with AVFoundation and iOS camera APIs: AVCaptureSession, AVCaptureDevice, video outputs, capture formats, frame rates, exposure, and device configuration.
• Strong experience designing and optimizing real-time camera, image, and video pipelines, with a solid understanding of media formats, encoding, buffer management, and capture quality and performance constraints.
• Strong performance mindset: CPU/GPU usage, memory, battery, thermal constraints, multithreading, and minimising buffer copies.
• Comfortable with iOS profiling tools such as Instruments, Time Profiler, Allocations, and Metal System Trace.
• Strong Swift skills. Experience with Metal, Core Image, or lower-level Apple APIs is a plus.
• Autonomous, pragmatic, and comfortable solving complex hardware/software limitations.

Requirements

• Experience with multi-camera capture or front/back video composition.
• Experience with Metal or GPU-accelerated image processing.
• Experience in consumer social, gaming, creative tools, or another real-time mobile product.

Benefits

• Competitive salary based on experience.
• Swile Lunch voucher.
• Gymlib (100% covered by Voodoo).
• Premium healthcare coverage with SideCare, 100% covered for you and your family.
• Wellness activities in our Paris office.
• €1,000 annual budget for attending tech conferences and professional events.
