Zusammenfassung

Wemolo in München, Germany, is seeking an experienced engineer to own the OS foundation and platform layer of our IoT devices, building and evolving a Yocto-based Linux image and the Python application layer on top of it within a dockerized main application.

You will work at the OS/hardware boundary, drive security, OTA updates, device observability, and cross-stack integration from kernel and drivers to Python software. A live coding interview is part of the process.

Qualifikationen

• Experience building Embedded Linux systems and working with Linux internals (bootloaders, drivers, systemd).
• Strong programming skills in C/C++ and Python; familiarity with Bash and GNU tools.
• Hands-on debugging of memory leaks, performance issues, and system-level bugs.

Aufgaben

• Design, build, and evolve the Yocto-based Linux distribution for ARM devices.
• Develop and maintain the Python application layer in a dockerized main app.
• Bridge kernel/driver integration to application software and ensure reliable OTA updates.

Jobbeschreibung

This position sits close to the embedded world, but it isn't traditional microcontroller firmware work. You'll own the operating system foundation and platform layer of our IoT devices - building and evolving our next-generation embedded Linux image - and develop the Python application layer that runs on top of it, inside our dockerized main application.

You'll work down at the OS and hardware boundary while shipping features up in the application layer. Typical areas include:

• Designing and maintaining our Yocto-based Linux distribution for ARM devices with limited compute
• Security on device, inter-process communication, networking, scheduling, observation
• Over-the-air (OTA) updates for both the OS and applications
• Integrating peripherals - watchdog, modem, AI accelerator - and improving their observability
• Bridging the system layer and the application layer through Python and Bash

The work spans from driver- and kernel-level integration in C/C++, to adapting our Linux distribution with Yocto to the underlying hardware layer, to debugging system-level failures such as memory leaks, up to writing the Python software that turns hardware capabilities into product features.

You will be expected to pass a live coding interview for this role.

What to expect

• Embedded Linux Platform: Design, build, and continuously evolve the next generation of our Yocto-based Linux distribution for ARM-powered IoT devices
• Application Development: Develop Python-based software that brings hardware capabilities to life and improves the reliability and performance of our products
• System Integration: Work across the full stack—from kernel and driver integration to application development—connecting hardware, operating system, and product features
• Device Reliability: Build secure, observable, and resilient systems, including OTA updates, networking, process communication, scheduling, and device monitoring
• Debugging & Troubleshooting: Analyze and resolve complex issues across the platform, including kernel, drivers, networking, memory management, and application software
• Ownership: Take end-to-end responsibility for your solutions, proactively improve our platform, and help shape engineering best practices
• Embedded Linux Expertise: Several years of experience developing Embedded Linux systems and confidence working with Linux internals, GNU tools, and Bash
• Engineering Mindset: Degree in Computer Science, Electrical Engineering, Physics, or equivalent practical experience
• Yocto Experience: Proven experience building, customizing, and maintaining Linux images using Yocto
• Systems Programming: Strong programming skills in at least one systems language such as C, C++, Rust, Go, or Java
• Python Development: Experience developing Python applications or a strong motivation to make Python your primary development language
• Low-Level Debugging: Hands-on experience with debugging tools such as GDB, tcpdump, Valgrind, UART, and JTAG, including troubleshooting memory leaks and system-level issues
• Operating System Knowledge: Solid understanding of Linux internals, bootloaders, systemd, drivers, kernel concepts, networking, and Docker

Extra points for

• Experience operating large-scale IoT fleets
• Knowledge of industrial hardware, cameras, AI accelerators, modems, or network devices
• Experience with computer vision, edge AI, or machine learning
• Familiarity with MQTT and Protocol Buffers (ProtoBuf)
