Job Details

Bring deep native mobile engineering experience with Android (Kotlin/Java) or iOS (Swift/Objective-C); strong Android expertise is particularly important initially.
Have experience building or maintaining mobile SDKs or platform libraries used by external developers.
Understand developer experience, API design, platform compatibility, and safe SDK upgrade paths.
Have experience developing performance-sensitive mobile software, including startup time, memory, battery, network efficiency, and background execution constraints.
Be familiar with mobile media and rendering pipelines, including screen capture, frame or bitmap processing, and video encoding or handling.
Understand mobile privacy and security principles, particularly when handling sensitive user data.
Communicate clearly in writing and verbally in English.
Be able to own complex products from concept to launch and work autonomously through ambiguity.
Bring a customer-oriented approach to understanding user needs and translating them into technical solutions.
Be willing to develop expertise across mobile platforms over time.
Experience with mobile session replay, screen recording, or mobile telemetry sampling is an advantage.
Additional useful experience includes H.264, MediaCodec, AVFoundation, rrweb, OpenTelemetry, React Native, Flutter, Go, or TypeScript.

Lead end-to-end development of the on-device mobile replay library, starting with Android and extending to iOS.
Design privacy-first capture features, including masking and consent controls.
Optimize capture performance across startup time, UI responsiveness, battery, memory, network, and disk usage.
Profile performance on real devices and provide controls for balancing replay fidelity with resource consumption.
Integrate replay with active RUM sessions, sampling decisions, and screen or navigation changes.
Collaborate with frontend and mobile observability teams on capture, upload, storage, inactivity handling, timeline playback, and the replay experience.
Evaluate data formats, APIs, and architecture for scalability and maintainability.
Establish quality and compatibility standards through automated testing, continuous integration, device and OS coverage, and backward-compatible SDK upgrades.
Gather customer feedback and support instrumentation and adoption of Mobile Session Replay.
Mentor engineers and contribute to technical direction and engineering practices.
