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.

Team Lead; Software Developer at Provider of industrial control systems for manufacturing and digital transformation
Industrial Communication | Proof of Concept: Controller-to-Controller Communication with OPC UA FX
Proof of Concept for OPC UA FX-based controller-to-controller communication between virtual programmable logic controllers (vPLC) on an industrial edge platform. A virtual test environment was set up on Debian Linux in two phases (including VMs and vPLCs), shared-memory communication (real-time information bus) was activated, and the RIB solution was integrated into a customized product firmware (including shared memory and PROFINET support) and deployed in containerized environments (Docker). Additionally, a virtual Ethernet connection was developed to simulate the network topology. Finally, commissioning, functional tests, sample application creation, comprehensive documentation, and customer support were completed.

About the technology
Bootloader Foundations
Das U-Boot, commonly called U-Boot or the Universal Boot Loader, is an open-source bootloader for embedded systems. It initializes hardware, loads operating systems and passes configuration data to Linux or another runtime. Its portability makes it a core component in development boards, industrial devices, networking equipment and custom electronics.
Boards and Startup Paths
U-Boot specialists adapt the boot process to a board’s processor, memory layout, storage and peripherals. They configure boot targets, environment variables, device trees and kernel arguments, then connect the bootloader with Linux images, initramfs files and root filesystems. This work often covers ARM, ARM64, RISC-V and PowerPC platforms.
Ecosystem and Tooling
The technology sits close to the Linux kernel and the embedded build ecosystem. Relevant skills include Yocto Project, OpenEmbedded, Buildroot, Barebox, GCC cross-compilers, Git and board support packages. Strong professionals also understand serial consoles, JTAG, flash layouts, TFTP, USB, eMMC, NAND, SPI-NOR and network boot workflows.
When Companies Need Specialists
- Porting U-Boot to a new board or system-on-module
- Updating boot flows for a new Linux kernel or storage design
- Diagnosing hangs before the operating system starts
- Adding verified or measured boot to an embedded product
- Maintaining board support across product variants
Companies bring in freelance expertise when a device must boot reliably across changing hardware, production revisions or field conditions. In Germany, this is especially relevant to industrial automation, automotive suppliers, medical equipment and connected devices. Remote work is practical when serial logs, hardware access and test procedures are available.
Security and Production Readiness
U-Boot work extends beyond making a board start. Specialists secure the boot chain with verified boot, trusted keys, image signing, rollback protection and carefully controlled environment storage. They also address recovery paths, watchdog behavior, update strategies and reproducible build inputs so production devices remain maintainable.
What Good Work Looks Like
A strong U-Boot professional can explain every startup stage and reproduce failures with logs, symbols and hardware tests. They document configuration choices, separate board-specific code from shared logic and validate cold boots, warm reboots, power loss and interrupted updates. Experience with the exact processor family, storage medium and build system is often more valuable than broad embedded knowledge alone.
Frequently asked questions
Curious about Das U-Boot? Here are the answers that come up again and again.
Das U-Boot is a bootloader used to initialize embedded hardware and load an operating system. It commonly starts Linux on custom boards, routers, industrial controllers, network equipment and connected products.
U-Boot has broad board support and a large embedded ecosystem, making it a common choice for products that need established boot flows. Barebox is another Linux-oriented bootloader and may suit teams that prefer its configuration model or existing hardware support.
A strong Das U-Boot specialist usually understands Linux kernel configuration, device trees, cross-compilation and board support packages. Yocto, OpenEmbedded, Buildroot, flash storage, serial debugging and secure boot are also valuable, depending on the product.
U-Boot work often depends on the processor, board design, boot media and build system involved. Ask for evidence of comparable bring-up, boot failure diagnosis or production update work rather than relying only on general embedded experience.
U-Boot assignments can often be handled remotely when the specialist has access to logs, documentation, build artifacts and a remotely reachable test device. On-site collaboration may still be useful during initial board bring-up, hardware faults or lab testing in Germany.
A capable U-Boot specialist defines a chain of trust from immutable or protected firmware through signed boot images. The work can include key handling, verified boot configuration, rollback protection, recovery behavior and validation on the target hardware.
Look for clear boot-flow documentation, reproducible builds and tests covering power cycles, recovery and interrupted updates. A strong U-Boot professional can show how logs led to a diagnosis and how board-specific changes were kept maintainable.
U-Boot sits at the boundary between hardware, firmware and Linux, so assignments often involve practical system-level problem solving. Professionals may work on board ports, boot-time performance, manufacturing images, secure startup or long-term maintenance for embedded products.
The average hourly rate of freelancers in Germany who have used Das U-Boot in their recent projects is 94 €, which corresponds to a daily rate of about 752 € based on an 8-hour working day.
