Zusammenfassung

1Komma5° is seeking a (Senior) Embedded Linux Engineer to develop and operate the 1K5 Heartbeat Gateway, an edge device connecting energy assets to our cloud ecosystem.

You will own the embedded Linux platform, collaborate with hardware, and ensure secure boot, device provisioning, and scalable manufacturing for large deployments. Strong Go and IoT experience is a plus.

Qualifikationen

• Hands‑on experience designing or maintaining assembly‑line flashing or device provisioning systems.
• Clear and effective communicator in English (German is a plus).
• Solid understanding of Linux system internals (boot process, kernel configuration, device drivers).
• Experience with board bring‑up and hardware debugging.
• Strong troubleshooting and analytical mindset.
• Ability to debug problems across hardware, kernel, and operating system layers.
• 5+ years of experience developing embedded Linux systems.
• Experience working closely with hardware engineers on custom embedded platforms.
• Experience developing edge services in Go.
• Familiarity with Eclipse Hono or similar IoT solutions.
• Experience with MQTT or device-to-cloud communication systems.
• Familiarity with Google Cloud Platform.
• Passion for climate tech and distributed energy systems.

Aufgaben

• Develop and operate 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.
• Collaborate with hardware engineers on board bring-up, validation, and debugging.
• Implement and maintain OTA update infrastructure using Mender.
• Design and maintain the assembly-line flashing and provisioning system, including automated workflows to flash firmware and provision identities.
• Troubleshoot and resolve system-level issues across hardware, kernel, and operating system layers.

Jobbeschreibung

• 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
• 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
• Technologies you will work with include:
• Yocto, Linux kernel, device trees, bootloaders, secure boot
• DevOps: CI/CD pipelines, secure OTA processes, Mender
• Embedded hardware (e.g. SoCs, compute modules, secure elements)
• Manufacturing processes: prototyping, assembly, flashing, and testing

Benefits

• You have the opportunity to work in our brand new offices in downtown Hamburg and Berlin and/or remotely
• Work in flat hierarchies, take on responsibility during your induction and work directly with parts of the management
• Use your technical equipment outside of work in your free time
• You are part of a fast‑growing company with a lot of development potential, where you can build something independently and feel your impact
• With your work, you support the megatrend energy and mobility transition and make a concrete contribution to the sustainable restructuring of our energy infrastructure
• Be active and use the offers of over 7,600 sports partners with the EGYM Wellpass
