Jens R.
Last position:
Platform Architect & Senior Developer at Direct client, industrial measurement technology, medium-sized company
- Technical leadership across hardware, firmware, and software teams; scope: hardware/firmware team (4 people) and leadership group (5 people)
- Consolidated and documented a product family that had grown over more than 15 years and aligned it with CRA compliance — from the bare-metal I/O module to the cloud interface.
- Provided the most important customer product with the essential requirements and architecture documentation within two months — for a firmware landscape that had grown over more than 15 years. It now supports the customer’s modernization strategy.
- Established a monthly reporting line to the supervisory board and executive board within three months: nine meetings since 12/2025. The report itself is versioned and built from the CI pipeline; it is based on automatically collected activity and release data instead of assessments.
- Built a container-based CI/CD infrastructure from scratch: cross-compilation, host tests, and documentation builds in one continuous pipeline.
- Introduced declarative QA gates for DevOps and development artifacts — from the start using lefthook instead of pre-commit, executed in a dedicated container image.
Technologies used: arc42, req42, tpo42, docToolchain, PlantUML, ArchiMate, C4 model, ADR, C, C++ (GTest), CMake, Bare Metal (ARM Cortex-M3/M7), OCI containers, Jenkins, lefthook, Prometheus, Grafana, SBOM, CRA, OPC, SCADA, PLC integration, IPv6 migration, Zero Trust, Sociocracy 3.0, Cynefin

Muhammad J.
Last position:
Embedded Linux Intern – IoT Sensor Prototype Development at DHL
- Built a modular C++ 20 embedded Linux acquisition system on a Raspberry Pi, synchronizing IMU and dual-camera data streams to sub-millisecond accuracy.
- Integrated retro-reflective and contrast sensors to trigger acquisition and detect gaps between sorter rails.
- Implemented SPI & I2C sensor communication, GPIO interrupt handling with libgpiod, and CSV & JSON output.
- Designed a multi-threaded acquisition pipeline and an SPSC queue between acquisition and writer threads.
- Built a Python/HTML/CSS based web-server and validated the prototype in a DHL warehouse for defect detection.
- Documented software behavior, configuration, and results for maintainable handover and further development.

About the technology
Arm in practice
Arm powers embedded devices, mobile systems, edge hardware, and server platforms. Companies bring in Arm specialists to make software run well on power-efficient CPUs, across Cortex-based boards, Raspberry Pi devices, and Arm64 server targets.
Typical work
- Port applications from x86 to Arm or Arm64
- Tune binaries for performance and power use
- Build and debug firmware, boot chains, and low-level software
- Adapt Linux systems, packages, and drivers
- Support testing on real hardware and emulators
Ecosystem and tooling
Strong professionals know the Arm architecture, instruction sets, cross-compilation, and target-specific build settings. They often work with GCC, Clang, CMake, Yocto, Buildroot, U-Boot, Linux, and debugging tools such as GDB and perf.
When companies need help
A freelance specialist is useful when a product must move to Arm, a board bring-up is stuck, or software behaves differently on target hardware than in the lab. In Cologne, this often matters for industrial, IoT, media, and infrastructure teams that need focused support without long hiring cycles.
What strong experts deliver
Good Arm experts do more than make code compile. They check ABI issues, endianness, alignment, and CPU features, then verify the full path from build system to deployment. They write clear notes, reproduce hardware issues, and keep changes safe for future maintenance.
Local collaboration
Teams in Cologne often mix on-site and remote work for Arm projects. On-site time helps with boards, labs, and hardware access, while remote work suits code review, build fixes, documentation, and support for distributed engineering teams across Germany.
Frequently asked questions
Everything clients usually want to know about Arm, in one place.
Arm is used for embedded devices, mobile products, edge systems, and increasingly servers and appliances. Companies choose it when they need efficient software on specific hardware, not just a generic desktop build.
Arm is the current company and architecture name, while ARM is the older all-caps form many people still search for. Arm64 usually refers to the 64-bit execution environment and is common in Linux, cloud, and server discussions.
Arm projects often involve cross-compilation, target-specific tuning, and more attention to hardware features than a typical x86 workflow. Compared with x86, teams usually care more about power use, board support, and deployment on a defined device family.
A strong Arm specialist usually also knows C or C++, Linux internals, build systems, and debugging on target hardware. For firmware or embedded work, knowledge of bootloaders, device trees, and hardware interfaces is often important.
Arm work can start with a small porting task or grow into a full platform migration. If the project touches toolchains, low-level boot code, or hardware bring-up, it is worth bringing in someone who has shipped similar work before.
Arm specialists can do a lot remotely, especially build fixes, code review, and performance analysis. On-site time in Cologne helps when the work depends on physical boards, lab access, or hands-on debugging with hardware.
Look for concrete work on Arm ports, target builds, and debugging on real devices. Good experts explain what changed, why it was needed, and how they verified it on the target system.
A Arm project may end with a working build, bootable image, ported application, fixed driver, or documented deployment process. For larger efforts, expect notes on build flags, hardware quirks, test steps, and any remaining risks.
