Junior SW Development Engineer

Location: Germany Department: Applied R&D

As a Junior SW Development Engineer you will design, implement, and maintain the Linux kernel, device drivers, and the full software stack for embedded controllers with a strong focus on advanced security features. Your work will directly contribute to the security and resilience of global communications infrastructure.

We offer

Opportunity to shape the secure Linux foundation of cutting-edge telecom infrastructure.

Access to advanced development tools, AI-assisted analysis platforms, and research resources.

Competitive salary, performance bonuses, and comprehensive benefits.

Continuous learning programs, mentorship, and support for professional certifications.

An inclusive, innovative culture that values curiosity, diversity, and work-life balance.

Linux kernel & driver development – create and maintain kernel code and custom device drivers.

Security-first platform design – embed security mechanisms throughout the stack, including:

Secure Boot and trusted hardware root of trust.

Disk and file-system encryption (e.g., dm-crypt, LUKS) for data-at-rest protection.

FIPS-validated cryptographic modules to satisfy regulatory and industry compliance.

Certificate-based authentication for secure boot, OTA updates, and inter-component communication.

Build and integrate the bootloader, root-filesystem, and runtime environment for embedded controllers.

Contribute to threat modeling, code reviews, static/dynamic analysis, and security testing (fuzzing, vulnerability scanning).

Collaborate with hardware engineers and application SW teams in a multi-national development project.

You Have

Bachelor’s or Master’s degree in Computer Science, Electrical Engineering, or a related field.

Strong interest in Linux kernel development and embedded systems (ARM).

Curiosity about device drivers (networking, storage, GPIO, I²C, SPI) and a desire to write/debug them.

Proven programming skills in C/C++ and scripting (Python, Bash).

Familiarity with version-control (Git) and CI/CD tools.

Interest in modern security fundamentals, especially: Secure Boot, Disk and file-system encryption techniques, FIPS-compliant cryptography.

Certificate-based authentication mechanisms.

Good problem-solving abilities and a collaborative mindset

It would be nice if you also had

Experience with embedded operating systems for telecom/networking equipment.

Experience with security feature implementations.
