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

About the technology
Bootloader foundation
Das U-Boot, short for Das Universal Boot Loader, is an open-source bootloader used to start operating systems on embedded hardware. It initializes processors, memory and peripherals, loads Linux or another operating system, and passes the required boot arguments. Its broad board support makes it a common foundation for custom devices.
Embedded use cases
Companies use Das U-Boot in products that need controlled startup, field updates and reliable recovery. Typical applications include industrial controllers, networking equipment, gateways, automotive electronics and connected devices. In Germany, it often appears in embedded products that must move from prototype hardware to repeatable production.
- Boot Linux on custom boards and system-on-modules
- Add recovery paths and robust update mechanisms
- Configure storage, networking and peripheral access
- Prepare production boot flows for embedded devices
Ecosystem and tooling
Strong specialists work across the bootloader, hardware and operating system boundary. Their toolkit may include ARM, ARM64, RISC-V or PowerPC platforms, device tree source files, SPL, Kconfig, Make, Yocto Project, OpenWrt and Buildroot. They also use serial consoles, JTAG probes, cross-compilers and board-specific flashing tools to diagnose startup failures.
When expertise matters
Freelance expertise is valuable when a board needs a new port, a vendor boot flow must be replaced, or a product requires dependable updates. Companies also bring in specialists when boot failures are difficult to reproduce or when hardware, Linux and manufacturing teams need one clear startup design.
- A new board reaches only a vendor prompt or fails before Linux starts
- Device tree, pin control or memory initialization is inconsistent
- Updates need rollback, recovery or verified images
- Boot time, diagnostics or manufacturing provisioning need improvement
Security and delivery
Das U-Boot projects often involve verified boot, signed images, trusted execution environments and secure key handling. Specialists should understand the complete chain from immutable hardware settings through the bootloader and kernel to the root filesystem. They should document configuration changes, reproduce builds and test interrupted updates rather than relying on a successful laboratory boot.
Choosing a specialist
Look for professionals who can explain the hardware startup sequence and show how their changes are tested on real boards. Useful evidence includes a clear board port, disciplined device tree changes, automated build and flash procedures, and practical recovery testing. Remote work is realistic when the project provides reliable lab access, serial logs and hardware shipped to the specialist; on-site collaboration can help during bring-up or production troubleshooting.
Frequently asked questions
Curious about Das U-Boot? Here are the answers that come up again and again.
Das U-Boot is a bootloader for embedded systems. It initializes hardware, loads Linux or another operating system, supplies boot parameters and can provide recovery or update functions before the main system starts.
Das U-Boot offers broad hardware support and a consistent open-source framework across many boards. A vendor bootloader may provide faster access to one chip family, but it can be less portable or harder to adapt when a product uses custom hardware.
A strong Das U-Boot specialist usually understands embedded Linux, device trees, cross-compilation and board-level debugging. Experience with Yocto Project, Buildroot, OpenWrt, storage interfaces, secure boot and update systems is also valuable.
A simple configuration change can be handled by a specialist familiar with the board family. A new Das U-Boot port needs deeper knowledge of processor initialization, memory, clocks, pin control, storage and the vendor documentation, plus access to functioning hardware.
Yes. Das U-Boot work can be handled remotely when the specialist has access to the target board through a lab, serial console, JTAG setup or a hardware kit. On-site work is useful during first board bring-up, hardware faults or production-line integration.
Ask how the specialist tests cold boots, reset paths, interrupted updates and recovery images. High-quality Das U-Boot work includes reproducible builds, documented configuration, meaningful serial diagnostics and tests on real target hardware.
Das U-Boot can participate in verified boot chains and validate signed images when the hardware and operating-system design support them. The specialist should define key storage, image formats, rollback handling and failure recovery together with the trusted execution environment.
Provide the board model, processor, memory layout, boot media, schematics where available, current logs and the intended operating system. For Das U-Boot work, it also helps to state whether the goal is a board port, boot-time improvement, secure boot, field updates or manufacturing automation.
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 754 € based on an 8-hour working day.
