The engineer will collaborate closely with backend, firmware, ML, hardware, R&D, growth, and executive stakeholders while owning app quality, code reviews, and performance. This is a demanding, high-autonomy role in a fast-moving health technology startup that explicitly describes an intense, 60+ hour-per-week culture.

Sample interview questions
I would explain the feature scope, define a unidirectional data-flow approach using ViewModels and immutable UI state, and describe how I used Compose state appropriately to prevent unnecessary recompositions. I would also cover profiling, testing, and measurable performance outcomes such as faster rendering or fewer crashes.
I would separate transport, device protocol, domain, and presentation concerns behind well-defined interfaces. I would use coroutines and Flow for asynchronous device events, model connection and error states explicitly, implement retry and reconnection logic, and build robust telemetry and tests for intermittent connectivity.
I focus reviews on correctness, maintainability, security, performance, and user impact, while distinguishing blocking issues from suggestions. I provide clear rationale, use shared standards and automated checks for repeatable concerns, and encourage small pull requests to keep feedback fast and actionable.
A strong answer would identify the production signal, such as crash reports, ANRs, startup latency, or dropped frames, then explain the investigation and remediation. It should include concrete changes, validation through monitoring or testing, and quantified results such as a lower crash rate or improved startup time.
I partner early with design to clarify behavior, accessibility, motion, and edge cases, then create reusable Compose components and design-system primitives rather than one-off implementations. This preserves visual quality while keeping the codebase testable, consistent, and easier to evolve.
