We believe that true security stems from relentless innovation. By combining elite engineering talent with agile technology and an AI-native operational culture, Stark turns complex defence challenges into field-tested, multi-domain solutions. Why Join Us? The software and systems you work on directly protect personnel and defend European and national sovereignty. You will work alongside industry-leading minds on autonomous systems, advanced propulsion, and secure cyber platforms. We foster a fast-paced, collaborative environment where bold ideas are supported by serious R&D backing. About the Team We are the architects of the physical experience. As part of our R&D-driven Electronics Department our Hardware Team turns visionary ideas into high-performance technology. In our enthusiastic and high-energy environment, we have the tools, the talent and the passion to engineer first-class products that lead the global market. Your Mission As a Senior Embedded Software Engineer you will play a key role in designing, developing, and optimizing software for real-time embedded systems in our platforms. You will work closely with cross-functional teams including hardware engineers, systems engineers, and flight software teams to deliver robust and secure embedded solutions.  You will design and develop low-level embedded firmware for safety-critical drone systems. You will own real-time firmware components running on STM32-based platforms, enabling reliable communication, control, and fault-handling capabilities in mission-critical environments. You will work close to the hardware, contributing to system integration, debugging, and safety-oriented embedded architecture in compliance-driven development environments. Responsibilities Develop embedded firmware in native C for STM32-based embedded systems Design and implement real-time software for safety-critical drone and aerospace applications Build low-level drivers, communication interfaces, bootloaders, and hardware abstraction layers Implement robust fault detection, watchdog, redundancy, and failsafe mechanisms Collaborate closely with hardware engineers to support board bring-up, validation, and system integration Analyse and troubleshoot complex hardware-software interaction issues using oscilloscopes, debuggers, and logic analysers Contribute to safety-critical development processes, verification activities, and technical documentation Support architecture discussions and technical decision-making for embedded platform development Ensure firmware reliability, maintainability, and deterministic real-time behaviour under demanding operating conditions Required Skills Bachelor's Master's degree (or equivalent) in Computer Engineering, Electrical Engineering, or related field.  5+ years of embedded firmware development experience Strong native C programming skills in embedded or low-level environments Hands-on experience with STM32 microcontrollers  Experience developing real-time embedded systems using RTOS or bare-metal architectures Ability to read schematics and collaborate effectively with hardware engineering teams Strong debugging and hardware interaction skills using embedded development and measurement tools Strong systematic and analytical thinking skills Nice-To-Have Experience with IEC 61508, ISO 26262, or DO-178C environments Fluent English and German, preferably at C1/C2 level or above SIL2, functional safety, or equivalent safety-critical software development experience Exposure to drone, avionics, robotics, or autonomous systems development Ex
