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
Embedded foundation
FreeRTOS is a lightweight real-time operating system kernel for microcontrollers and small embedded systems. It schedules tasks, manages timing and synchronization, and helps firmware respond predictably to hardware events. Companies use it in connected products where memory, power and response time are tightly constrained.
Where it runs
FreeRTOS supports products such as industrial sensors, medical devices, smart appliances, robotics components, tracking equipment and consumer electronics. It can run on microcontrollers from many silicon vendors and is commonly combined with vendor hardware abstraction layers, board support packages and low-level drivers. In Germany, it is relevant to manufacturers building connected industrial and automotive-adjacent devices.
Ecosystem and tooling
The kernel is only one part of a production system. Strong specialists work with:
- ARM Cortex-M and other microcontroller architectures
- Device drivers, interrupts, timers and inter-task communication
- TCP/IP, MQTT, BLE, Wi-Fi and secure boot flows
- AWS IoT integrations and the former Amazon FreeRTOS ecosystem
- Cross-compilers, JTAG debuggers, trace tools and hardware test rigs
When expertise matters
Companies bring in freelance expertise when firmware must move from prototype to dependable product, or when an existing codebase shows timing, memory or concurrency problems. Support is also valuable during board bring-up, connectivity integration, safety reviews and release preparation.
- A new board needs a stable scheduler and hardware integration
- Tasks compete for memory, CPU time or shared peripherals
- Wireless devices require reliable cloud communication
- The team needs testable firmware and repeatable builds
Delivery approach
A capable professional starts with hardware constraints, timing requirements and failure modes rather than adding tasks indiscriminately. They define priorities, stack sizes, interrupt boundaries and synchronization rules, then validate them with traces, static analysis and hardware-in-the-loop tests. They also document configuration and recovery behavior for future maintenance.
Remote work is practical when source code, schematics, build systems and test access are available. German companies may still need on-site collaboration for lab equipment, production-line trials or regulated device work, while clear English documentation supports distributed teams.
Choosing a specialist
Look for evidence of shipped firmware, not only familiarity with the kernel API. A strong specialist can explain scheduling decisions, diagnose race conditions, measure worst-case timing and reduce resource use without weakening reliability. Experience with the target microcontroller, communication protocol, build pipeline and debugging hardware is often as important as FreeRTOS knowledge.
Ask for examples of tests, trace data, code reviews and release documentation. The right professional can also separate kernel concerns from application logic, assess whether a different real-time approach is justified, and leave the team with maintainable code.
Frequently asked questions
Not sure where to start with FreeRTOS? These answers cover the essentials.
FreeRTOS is used to coordinate real-time tasks on microcontrollers and other resource-constrained devices. It supports firmware for sensors, appliances, industrial equipment, connected products and embedded control systems where predictable response matters.
FreeRTOS provides scheduling, queues, semaphores, timers and task isolation that a bare-metal design must implement directly. Bare metal can be simpler for very small applications, while FreeRTOS becomes useful when several activities must run concurrently and remain maintainable.
Amazon FreeRTOS was the former name for an AWS-oriented distribution and ecosystem built around the FreeRTOS kernel. The current ecosystem is commonly discussed through FreeRTOS and AWS IoT services, with cloud connectivity, security and device management added around the kernel.
FreeRTOS work usually benefits from knowledge of C or C++, microcontroller peripherals, interrupt handling and board bring-up. Useful adjacent skills include MQTT, TCP/IP, BLE, secure boot, OTA updates, cross-compilation, JTAG debugging and hardware-in-the-loop testing.
FreeRTOS projects need a specialist who has handled the target hardware and understands timing, concurrency and memory limits in production conditions. A smaller prototype may need focused firmware support, while safety-sensitive or connected products call for deeper testing, debugging and release experience.
FreeRTOS work can often be done remotely when repositories, schematics, build tools and remote access to test hardware are available. On-site sessions in Germany may be useful for board bring-up, lab measurements, production trials or equipment that cannot be accessed securely from outside the workplace.
FreeRTOS quality is shown through predictable timing, clear task boundaries, controlled resource use and evidence from testing. Review how the specialist handles race conditions, priority inversion, stack sizing, watchdog recovery, trace analysis and documentation rather than relying on a list of APIs.
FreeRTOS is a strong option when a project needs a widely supported kernel with a small footprint and broad microcontroller compatibility. The decision should also consider licensing, vendor support, safety requirements, networking needs, existing team skills and whether a vendor-specific RTOS or a richer embedded operating system fits the product better.
The average hourly rate of freelancers in Germany who have used FreeRTOS in their recent projects is 92 €, which corresponds to a daily rate of about 734 € based on an 8-hour working day.
Of the freelancers in Germany who have used FreeRTOS in their recent projects, 86% hold at least a Bachelor's degree, 57% hold at least a Master's degree, and 5% hold a doctorate.
On average, freelancers in Germany who have used FreeRTOS in their recent projects have 19 years of professional experience, with a single engagement typically lasting around 3.3 years.
