Job Zusammenfassung
In dieser Rolle entwickelst du das Embedded Linux für das 1K5 Heartbeat Gateway, inklusive Boot-Ketten, OTA-Updates und Hardwareintegration, und sorgst für die Qualität und Sicherheit beim Deployment tausender Energiegeräte.
Job Technologien
Deine Rolle im Team
- At 1KOMMA5°, we connect and manage distributed energy devices at scale. As a (Senior) Embedded Linux Engineer, you will play a key role in developing and operating the 1K5 Heartbeat Gateway, the edge device that securely connects thousands of energy assets to our cloud ecosystem.
- You will work primarily on the embedded Linux platform running on our gateway hardware, collaborating closely with hardware engineering to ensure that the system is robust, secure, and ready for large-scale manufacturing and field deployment.
- Your work will directly contribute to the reliability, security, and long-term maintainability of the distributed energy infrastructure powering the energy transition.
- Key responsibilities include but are not limited to:
- Develop and maintain the embedded Linux distribution for our gateway using Yocto.
- Design and maintain the boot chain and secure boot architecture, ensuring trusted firmware execution and reliable device startup.
- Develop and maintain device tree configurations, drivers, and hardware interfaces.
- Work closely with hardware engineers on board bring-up, hardware validation, and debugging, ensuring smooth integration between hardware and the Linux platform.
- Implement and maintain OTA update infrastructure using Mender, ensuring safe updates, rollback mechanisms, and long-term maintainability of devices in the field.
- Design and maintain the assembly-line flashing and provisioning system, including automated workflows to flash firmware, provision device identities, and run factory diagnostics during manufacturing.
- Troubleshoot and resolve system-level issues across hardware, kernel, and operating system layers, ensuring robustness, recoverability, and stability of gateway fleets deployed at scale.
