Android Engineer

We’re looking for an Android Engineer to lead the development of the mobile applications that control our industrial robots for construction automation. This role is open to exceptionally strong candidates with 1-3 years of experience who can operate at a senior level — you’ll own the Android codebase end-to-end, set technical direction for the mobile stack, and work closely with our robotics team to build interfaces that operators rely on in real-world, high-stakes environments. If you’re excited about pushing robotics applications forward and want ownership over a critical piece of the product, we’d love to talk.

Requirements• 1-3 years of professional Android development experience, but exceptionally strong: a track record of shipping complex, production-grade native apps and operating with senior-level ownership and judgment

• Expert-level Kotlin (Java experience a plus); deep understanding of the Android SDK and app architecture (MVVM, Clean Architecture, etc.)
• Strong command of Kotlin Coroutines, dispatchers, and structured concurrency, and a solid grasp of Android component lifecycles (Activity/Fragment/ViewModel/Service) and how they interact with real-time data streams
• Proven experience designing and maintaining apps that handle real-time data, low-latency communication, and hardware/device control
• Familiarity with Magisk, root-level Android customization, and system-level modifications on custom or embedded hardware
• Strong grasp of concurrency, multithreading, and performance optimization for resource-constrained or safety-critical applications
• Experience with networking protocols (REST, WebSockets, MQTT, or similar) for real-time robot control and telemetry
• Solid understanding of SQLite and relational databases, including schema design and query/database performance optimization
• Experience building or maintaining backend services with Python and FastAPI, including RESTful API design
• Demonstrated ability to drive code quality through reviews, testing, and sound architectural decisions
• Comfortable owning technical decisions independently and collaborating cross-functionally with robotics, hardware, and backend teams
• Familiarity with Git, CI/CD pipelines, and Agile development practices
• (Bonus) Experience building or customizing HMI (Human-Machine Interface) layers for industrial, embedded, or field-operated devices
• (Bonus) Experience with Bluetooth/BLE, ROS, or other robotics communication frameworks

Responsibilities• Architect, build, and maintain native Android applications for robot control and monitoring

• Design and build the HMI (Human-Machine Interface) layer that operators use to control and monitor robots in the field
• Define and evolve the technical roadmap for the mobile platform
• Design intuitive, reliable UI/UX for operators working in demanding field conditions
• Apply sound use of Kotlin Coroutines, dispatchers, and lifecycle-aware components to keep the app responsive and stable under real-time load
• Design and optimize local data storage (SQLite) for performance and reliability
• Optimize app performance, stability, and real-time data handling
• Contribute to backend API work (FastAPI/Python) when needed to unblock mobile features
• (Bonus) Work with Magisk and system-level Android customization to tailor the OS environment for our hardware (kiosk mode, permissions, device provisioning, etc.)

Benefits• Lead mobile engineering at a fast-moving startup at the forefront of robotics and AI innovation

• Shape technology that will directly impact and modernize the construction industry
• Work alongside a talented, passionate team building real-world robotics products
• High ownership role with significant influence over technical direction
• Competitive compensation and the opportunity to make a lasting impact on the industry
