Job Details

Bring deep native mobile engineering experience on Android (Kotlin/Java) or iOS (Swift/Objective-C); Android depth is a priority for the first hire.
Have built or maintained mobile SDKs or platform libraries used by external developers.
Have experience with performance-sensitive code, including startup time, memory, battery, network efficiency, or background execution limits.
Be comfortable with mobile media and rendering pipelines, including screen capture, frames or bitmaps, and video encoding or handling.
Write and speak clearly in English.
Be able to own a product from 0 to 1 in ambiguous problem spaces, break large problems into increments, and work autonomously.
Take a user-centered approach and build understanding of customers' contexts and goals.
Apply thoughtful privacy and security practices on user devices, including handling sensitive data.
Use AI tools in engineering workflows and exercise judgment about where they help.

Own the on-device replay library end to end, starting with Android and extending to iOS.
Design masking and consent controls so sensitive data does not leave the device.
Measure capture overhead on real devices, including startup time, UI responsiveness, battery, memory, network use, and disk.
Build adapters connecting replay to the active RUM session, sampling decisions, and screen or navigation changes.
Work with Frontend and Mobile Observability teams on capture, upload and storage, session inactivity handling, the timeline player, and the mobile replay experience.
Evaluate format and API tradeoffs for the replay product.
Define automated tests, CI, device and OS coverage, and backwards-compatible SDK upgrade paths.
Join customer calls, gather structured feedback, and help teams instrument and adopt Mobile Session Replay.
Mentor engineers and help grow technical leadership in the team.
