• Support application porting and compilation against the new Yocto 5.0 toolchain.
• Maintain and update existing Yocto layers, recipes, and build configurations.

Gateway Application Development & Maintenance

• Develop, maintain, and debug gateway applications written in Python and C communicating via MQTT.
• Support application integration with the Yocto 5.0 BSP.
• Validate end-to-end gateway functionality.
• Contribute to resolving development backlog items, identified vulnerabilities, and bugs.
• Work in a hybrid environment.
• Participate in agile ceremonies, sprint planning, and technical reviews.
• Document technical decisions, migration progress, and known issues.

Required Qualifications

• 7+ years of embedded Linux development experience.
• Strong hands-on experience with Linux kernel, U-Boot, BSP, and driver development.
• Strong Yocto Project / OpenEmbedded expertise, including recipe authoring, layer creation, custom BSP development, and multi-version migration.
• Proficiency in Python and C for embedded application development and debugging.
• Experience with device tree authoring and debugging for ARM-based platforms.
• Strong debugging and root-cause analysis skills, including supplier firmware and third-party component issues.
• Ability to work independently and adapt to changing priorities in a small, fast-moving team.
