Job summary

Unknown company is seeking an experienced Embedded Linux Engineer to own and evolve the OS foundation and platform layer of IoT devices. You will work from kernel/driver integration to Python-based application development, with emphasis on Yocto, device reliability, and OTA updates.

Strong expertise in embedded Linux, Yocto, and C/C++ is required, along with Python development and low-level debugging skills. Fluent English is essential, and a live coding interview is expected.

Qualifications

• Several years of experience developing Embedded Linux systems and confidence working with Linux internals, GNU tools, and Bash
• Degree in Computer Science, Electrical Engineering, Physics, or equivalent practical experience
• Proven experience with Yocto for building, customizing, and maintaining Linux images
• Strong programming skills in at least one systems language such as C, C++, Rust, Go, or Java
• Experience developing Python applications or strong motivation to make Python primary language
• Hands-on debugging with tools such as GDB, tcpdump, Valgrind, UART, and JTAG
• Solid understanding of Linux internals, bootloaders, systemd, drivers, kernel concepts, networking, and Docker
• Fluent English (C1)

Responsibilities

• Design, build, and continuously evolve the next generation of our Yocto-based Linux distribution for ARM-powered IoT devices
• Develop Python-based software that brings hardware capabilities to life and improves reliability and performance
• Bridge the system layer and the application layer through Python and Bash
• Work across the full stack—from kernel and driver integration to application development
• Ensure device reliability with OTA updates, networking, process communication, scheduling, and monitoring
• Analyze and resolve complex issues across the platform, including kernel, drivers, networking, memory management, and application software

Job description

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 will 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

Inspire us by

• 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

• Language Skills: Fluent English (C1)

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)

What we offer

• Flexibility & Responsibility: Your workday, your performance - Our hybrid model empowers you to focus from home, get fresh perspectives during workation, and connect in person during our Anchor Days (Tuesday to Thursday)

• Tailored Mobility: Full speed ahead - Whether it's sustainable bike leasing or a public transport subsidy, we keep you flexible and on the move

• Measurable goals: Our agile methods allow you to directly measure your impact on our product and company success

• Team Culture & Networking: Real connections - also beyond the day-to-day. Celebrate successes with us at legendary team events and OKR parties

• Productive Environment: Brainfood deluxe - Whether it's portafilter coffee, Bella&Bona online cafeteria, fresh fruit or our muesli bar - your wellbeing fuels your performance

• Health & Balance: Stay in balance with EGYM Wellpass or Urban Sports Club - access 1,000+ gyms and wellness spots across Germany

• Top Equipment & Ergonomics: Mac or Windows, in the office or remote - we make sure you're set up for efficiency and comfort

• Dress Code? Your Code: What you do matters more than what you wear - dress in whatever makes you feel your best

Innovation through diversity

Regardless of your background, origin, gender identity, or individual circumstances, it's your personality that interests us. That's why we're committed to building a culture of collaboration and respect, where every team member has a voice, can grow, and feels valued with us.
