• Develop and integrate embedded platform services, middleware, device interfaces, and hardware abstraction components across Android and Embedded Linux systems. 

• Analyze system performance using benchmarking, profiling, and instrumentation, and implement optimizations. 

• Incorporate software quality attributes into architecture, design, development, and delivery activities. 

• Contribute to and review software methodologies, product designs, models, and technical documentation. 

• Collaborate with developers and architects across time zones and international sites in a scaled agile environment. 

• Partner with the product manager and test lead to develop user stories, refine acceptance criteria, and define test designs. 

• Investigate and resolve field issues in existing products through thorough system impact analysis, diagnostics, and debugging. 

• Ensure secure coding practices are followed throughout development. 

Required Qualifications 

• Bachelor’s degree in Computer Science or Electrical or Electronic Engineering 

• 10+ years of hands-on professional experience designing and developing applications and algorithms in Java and Kotlin for Android/Linux platforms, including 5+ years of Kotlin experience.  

• 10+ years of embedded software development and platform architecture experience. 

• 10+ years of architecture and development experience with Embedded Linux and Android, including Android OS root/system-level development, device drivers, and Android tablet hardware integration. 

Preferred Qualifications 

• Experience in the HVAC domain and Internet of Things (IoT) applications. 

• Experience with embedded platform services, middleware, device interfaces, hardware abstraction, and cross-platform libraries. 

• Experience in system performance analysis, benchmarking, profiling, instrumentation, and optimization. 

• Practical experience with SDLC tools such as Git and Azure DevOps. 

• Strong communication and collaboration skills in a global team environment. 

• Self-motivated, committed to continuous learning, and able to adapt to a fast-paced startup environment 

• Experience with the Android platform, middleware, framework, native services, HAL, NDK, JNI, and AIDL; working knowledge of Android architecture layers (Linux Kernel, HAL, Runtime, Framework, Applications). 

• Experience with Linux internals, including processes, threads, IPC, scheduling, memory, storage, networking, and system services. 

• Experience with embedded-device observability, telemetry, health monitoring, diagnostics, logging, and remote debugging. 

• Experience with embedded platform security, including secure boot, keys, certificates, signing, TPM/TEE, secure updates, and network security. 

• Experience with the Android SDK, different Android versions, Android UI design principles, patterns, and best practices. 

• Experience with the open-source Android ecosystem and common libraries; familiarity with RESTful APIs connecting Android applications to back-end services. 

• Experience with offline storage, threading, and performance tuning. 

• Experience with Java build and package management tools such as Gradle and Maven. 

• Experience with testing libraries and automation frameworks such as JUnit, Espresso, and Robolectric, including hands-on application testing across multiple devices and form factors.
