Stellenausschreibung: FREELANCE - Embedded Engineer (m/w/x) - München

Arbeitgeber bzw. Arbeitsvermittler: requisimus Holding GmbH in Hamburg

Branche: Dienstleistungen

Kategorie: Verwaltung/Dienstleistung

Stellenbeschreibung: Project DescriptionLocation: München Work Mode: On-site Project Duration: 6–8 Months Overview This project consists of two technical work packages aimed at enhancing the quality, reliability, and testability of embedded firmware. The first work package focuses on building HIL test environment, while the second centers on implementing a comprehensive unit?testing framework. An automotive background is not required . However, strong hands on coding skills in embedded C/C++ or Python are essential . Tasks Work Package 1 — HIL Test Environment Scope Design, implement, and validate a Hardware?in?the?Loop (HIL) test environment to enable automated and reproducible testing of embedded firmware running on STM32 platforms. The engineer will be responsible for defining the HIL architecture, developing target?specific components, creating host?side tooling, and ensuring full integration of the setup. Key responsibilities include: Designing the architecture and system interfaces of the HIL environment Bringing up STM32F4/H7 hardware including BSP and peripheral configuration Developing and integrating custom Zephyr RTOS drivers Creating device tree definitions, overlays, and configuration layers Building Python-based test automation and host control scripts Validating the entire HIL setup, ensuring deterministic and automated test execution. Required Skills STM32F4/H7 Expertise Board bring-up, BSP development Peripheral drivers (SPI, I²C, ADC/DAC, DMA, timers) Zephyr RTOS Custom driver development (DAC1001B, AD7124?4) Device Tree creation, overlays, and version control workflows Python for Test Automation Automated test orchestration Host-side tooling and scripting Integration with CI systems Requirements Work Package 2 — Unit Testing Scope Establish a structured unit?testing framework for embedded firmware components to ensure code quality, maintainability, and regression prevention. This includes defining the testing approach, implementing test suites, and integrating everything into automated build workflows. Key responsibilities include: Designing and setting up the unit?testing architecture Writing test cases for core firmware modules Integrating GoogleTest into CI pipelines Creating reusable templates and documentation for future development Required Skills Embedded C/C++ Modular design, interfaces, and testability principles GoogleTest (GTest) Writing and structuring test suites Mocking/stubbing hardware interfaces Integration in automated build systems Additional Notes: Automotive industry experience is not mandatory . The decisive factor for this project is practical coding capability in embedded development and Python automation.
