Description

  • Own the end-to-end Android architecture for native Android on custom ARM-based embedded hardware.
  • Design an offline-first, modular local-data system with encrypted per-profile storage and future cloud-sync support.
  • Integrate onboard cameras, sensors, controlled lighting, and physical hardware controls into the device experience.
  • Build shared hardware-abstraction layers for camera management, physical input, and device lifecycle behavior.
  • Develop the on-device Kotlin experience and UI navigated by physical controls from approved designs and specifications.
  • Implement Bluetooth audio, Wi-Fi sync, OTA updates, offline device-to-device transfer, and casting or streaming.
  • Build and maintain companion mobile apps and device-to-companion integration, including pairing, transfer, and shared data contracts.
  • Meet performance targets for cold boot, profile switching, and camera initialization while managing constrained device resources.
  • Verify features on real hardware before handoff, conduct code reviews, and set the Android review bar.
  • Lead technical planning across device and companion-app work, surface risks early, and guide the team toward clear implementation decisions.

Requirements

  • 5+ years building production Android applications in Kotlin.
  • Deep, current Android platform expertise.
  • Hands-on experience building Android for custom, embedded, or non-phone hardware.
  • Experience integrating device hardware such as cameras, sensors, peripherals, or physical controls.
  • Experience designing offline-first or local-data architectures with future sync in mind.
  • Connectivity experience with Bluetooth, Wi-Fi, OTA updates, or device pairing.
  • A track record of owning Android architecture end-to-end as a senior engineer.
  • Strong Android fundamentals, including lifecycle, state management, performance, and memory.
  • Experience taking ambiguous requirements through to production on real hardware.
  • A strong quality discipline with typed, tested code and on-device verification before QA.
  • Ability to estimate work, commit within a delivery cycle, and reliably deliver.
  • Excellent professional English, spoken and written.
  • Strong written communication and proactive, independent work in a fully remote team.
  • Reliable overlap with standard US Central Time business hours.
  • Fluent, practical use of AI coding tools as part of your engineering workflow.
  • Based in Latin America and able to work as an independent contractor.
  • Platform or OS-adjacent experience such as AOSP-level engineering, NDK/JNI, or custom ROM/HAL work is preferred.
  • Multi-camera work with Camera2 or CameraX, on-device computer vision, or ML and AR using GPU/NPU is preferred.
  • Bluetooth audio (A2DP/HFP), Matter, or Thread experience is preferred.
  • Experience building or operating an OTA update pipeline is preferred.
  • Companion app and device-pairing experience is preferred.
  • Mentoring or technical leadership of other engineers is preferred.
  • A portfolio, GitHub, or code samples you can share is preferred.

Benefits

  • Compensation of $5,000 USD per month.
  • Remote contract engagement for an independent contractor.
  • Location flexibility for candidates based in Latin America.
  • Work aligned to standard US Central Time business hours with team overlap.
  • Opportunity to own a senior technical role with direct impact on the product.
  • Close-knit team environment with visible impact on client outcomes.
  • Use of modern AI coding tools and agents to improve speed, quality, and focus.
