With exciting growth plans and cutting-edge projects, there has never been a better time to join our incredible team. About the role We are building the software that drone pilots actually look at. The application runs on the aircraft's smart controller — DJI RC Pro / RC Plus class hardware — as an Android app with a Kotlin presentation layer, sitting on top of a shared Kotlin Multiplatform core that also powers our backend. This role is front-end first. You own the interface: live telemetry, video, mission state, and the controls a pilot uses in the field. You will also co-own the shared KMP core with the rest of the team — the domain model, protocol and sync logic that the UI renders and the backend serves. We do not have a designer yet. The right person here has opinions about interface design and can carry a screen from rough intent to something a pilot can use in bright sunlight with one hand — working with a designer later, but not blocked without one today. This is a senior individual contributor role. You are not managing anyone; you are expected to make good calls independently and raise the quality bar by example. What you will do Build and own the Android presentation layer in Kotlin and Compose: flight UI, telemetry displays, video, mission planning and review. Shape the interface itself — layout, interaction, information hierarchy — in the absence of a dedicated designer. Co-own the shared Kotlin Multiplatform core alongside the rest of the team: domain model, protocol, persistence, sync. Render live telemetry and video streams smoothly on modest controller hardware. Design for the field: degraded links, stale data, gloves, sunlight, vibration, one-handed use. Work alongside the engineers handling the DJI SDK integration, and consume the flight state they expose — growing into that layer yourself over time if it interests you. Validate on real hardware. The emulator only gets you so far; expect to be part of field testing. Requirements 1. Engineering fundamentals 5+ years building and shipping production software. Expert-level Kotlin: coroutines, structured concurrency, Flow, generics. Sound architecture instincts: modularization, clear layer boundaries, domain logic kept out of framework and UI code. Comfortable with testing and CI/CD as part of normal work, not an afterthought. Able to work autonomously in a fully remote, distributed team, and to communicate clearly in writing. Professional working proficiency in English. 2. Android 4+ years of Android development with applications shipped and maintained in production. Solid grasp of the application lifecycle, foreground and bound services, process death, and keeping a long-running session alive behind the UI. Performance work as a habit: profiling, memory, frame timing, battery and thermal behaviour on constrained devices. Comfortable targeting older API levels and non-standard hardware — controller devices lag well behind mainstream Android and have no Play Services to lean on. 3. Presentation layer in Kotlin — the core of this role Deep Jetpack Compose: state hoisting, recomposition and stability, DerivedSoft, custom layouts, Canvas drawing, animation, gesture handling. Sound UI architecture: unidirectional data flow, a single source of truth, Flow-driven state, no business logic in composables. Rendering high-frequency streams without dropping f…
