Senior Embedded Software Engineer (All genders)

At Stark, we forge the future of European and national security through cutting-edge, AI-driven technology and unmatched engineering precision. As a premier defence technology company, our mission is clear: to equip NATO Allies and their partners with next-generation autonomous defence platforms and advanced AI-driven software built to perform in the world’s most demanding environments. 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 Our embedded software team develops real-time safety-critical firmware and low-level software for autonomous defense platforms. We partner closely with hardware, systems, and controls engineers to take novel designs from concept to flight-ready software. You will join an agile cross-functional team focused on high-reliability execution in mission-critical environments. YOUR MISSION As a Senior Embedded Software Engineer, you will architect, implement, and validate firmware and low-level software for autonomous defense platforms. You will drive hardware-software integration and ensure system reliability and safety standards are met across multi-domain environments. WHAT YOU WILL DO AT STARK • Architect and write high-performance C/C++ software and firmware for microcontroller and RTOS-based embedded systems. • Develop low-level device drivers, bus communication protocols (CAN, SPI, I2C, Ethernet), and hardware abstraction layers. • Lead hardware-software integration, system bring-up, and hardware-in-the-loop (HIL) testing in laboratory and field environments. • Optimize software for low latency, memory constraints, and deterministic execution on embedded microcontrollers. • Collaborate with hardware, systems, and QA teams to design robust fault-handling and safety-critical fail-safe mechanisms. WHAT YOU BRING TO THE MISSION • 5+ years of professional experience in embedded software development using C and C++. • Deep experience with Real-Time Operating Systems (RTOS such as FreeRTOS, Zephyr, or VxWorks) and bare-metal programming. • Solid understanding of microcontrollers (ARM Cortex-M/R), peripheral interfaces (SPI, I2C, UART, CAN, Ethernet), and hardware schematics. • Proficiency with debugging equipment (logic analyzers, oscilloscopes, JTAG/SWD debuggers) and automated testing frameworks. • Degree in Electrical Engineering, Computer Science, Embedded Systems, or a related technical field. NICE TO HAVE • Experience with functional safety standards (ISO 26262, IEC 61508, or DO-178C). • Familiarity with Embedded Linux, ROS/ROS2, or Rust for embedded systems. • Prior experience in aerospace, robotics, defense, or automotive industries.
