IoT Embedded Systems Engineer

Join a fast-growing IoT/SaaS start-up revolutionising a niche area of industrial process management. They are building toward global leadership in smart analytics and automation for the manufacturing sector. The team is young, highly motivated, and driven by a genuine ambition to make an impact.

Your Tasks

• Own the development of IoT systems with a focus on embedded software, system architecture, and hardware/firmware integration
• Design and develop embedded software for IoT products on microcontroller and (optionally) Linux-based systems, with an emphasis on robustness, efficiency, and scalability
• Provide technical support to hardware development in collaboration with external partners; review and challenge PCB designs for functionality, quality, and manufacturability
• Work closely with mechanical, software, and cloud teams to ensure seamless system integration
• Define and refine product requirements from concept through to series production in collaboration with various stakeholders
• Develop and integrate prototypes, and support the handover to series production in coordination with external partners
• Co-design and further develop the embedded platform, including MCU and (optionally) Linux/Yocto-based components
• Develop pragmatic test strategies to ensure functionality and reliability across hardware and firmware
• Support manufacturing and development partners with debugging, documentation, and production ramp-up
• Provide Level 3 technical support for complex system, firmware, and hardware issue
• Willingness to travel (5–10%) to support partners, validations, and product launches

Your Profile

• Degree in electrical engineering, embedded systems, computer science, or a related field (university of applied sciences or university level) — or equivalent practical experience
• Several years of hands-on experience in embedded development (hardware-related and firmware)
• Basic understanding of hardware design and PCB layouts; ability to critically assess design decisions and collaborate with hardware teams
• In-depth knowledge of embedded firmware development and software architecture for microcontrollers (e.g. ARM Cortex, ESP32, STM32)
• Experience with sensor integration and wireless communication protocols such as BLE and WiFi
• Experience with embedded Linux systems (e.g. Yocto), particularly with SoMs and MCU + Linux architectures, is an advantage
• Holistic system understanding spanning mechanics, sensors, actuators, and their integration into robust IoT products
• Hands-on experience with hardware testing, debugging tools, and automated production testing
• Familiarity with certification standards (CE, FCC, etc.) is an advantage
• Fluent in German and English; additional languages are a plus

What They Offer
