Senior Embedded Software Engineer (All genders)

STARK

ABOUT US STARK is a new kind of defence technology company revolutionising the way autonomous systems are deployed across multiple domains. We design, develop, and manufacture high-performance unmanned systems that are software-defined, mass-scalable, and cost-effective — providing operators with a decisive edge in contested environments. We are focused on delivering deployable, high-performance systems — not future promises. In a time of rising threats, STARK is bolstering the technological edge of NATO Allies and their Partners to deter aggression and defend Europe, today. ABOUT THE TEAM We are the architects of the physical experience. As part of our R&D-driven Electronics Department, our Embedded Software 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 You will bridge the gap between software development and hardware integration, designing robust test suites that push our firmware to its limits. You thrive in the lab and enjoy "breaking" things to make them better, and you have a deep understanding of how software interacts with physical circuitry. RESPONSIBILITIES * Test Strategy & Design: Develop comprehensive test plans, cases, and procedures based on functional requirements and design specifications. * Automated Testing: Design, build, and maintain automated test frameworks and scripts (robotframework/Python). * Hardware-in-the-Loop (HIL): Configure and operate HIL, SIL, and MIL simulation environments to validate software behavior in real-world scenarios. * Debugging & Analysis: Utilize oscilloscopes, logic analyzers, and protocol analyzers (CAN, SPI, I2C) to troubleshoot complex hardware/software interactions. * Defect Management: Identify, document, and track software defects; collaborate closely with firmware developers to verify fixes and perform regression testing. * Compliance: Ensure testing processes meet industry-specific standards (e.g., ISO 26262, IEC 62304, or DO-178C) where applicable.  QUALIFICATIONS * Education: Bachelor’s degree in Electrical Engineering, Computer Science, or a related field. * Experience: 5+ years of experience in embedded software testing or development. * Technical Proficiency: * Strong programming skills in scripting languages like Python. * Experience with embedded RTOS (e.g., FreeRTOS, Zephyr) or bare-metal environments. * Familiarity with communication protocols: UART, SPI, I2C and CAN. * Tools: Experience with Git, Jira, and lab equipment (Multimeters, Power Supplies, Debuggers like J-Link).  NICE TO HAVE * The "Testing Mindset": A proactive approach to identifying edge cases and potential failure points. * Adaptability: Comfortable working with evolving hardware prototypes and early-stage firmware. * Communication: Ability to translate complex technical bugs into actionable reports for stakeholders. * German language skills.

STARK

ABOUT US STARK is a new kind of defence technology company revolutionizing the way autonomous systems are deployed across multiple domains. We design, develop and manufacture high performance unmanned aerial and terrestrial systems that are software-defined, mass-scalable, and cost effective. This provides our operators with a decisive edge in highly contested environments. We’re focused on delivering deployable, high-performance systems—not future promises. In a time of rising threats, STARK is bolstering the technological edge of NATO Allies and their Partners to deter aggression and defend Europe—today. YOUR MISSION We're not looking for someone who executes a spec. We're looking for someone who becomes the spec. Hand this person a napkin sketch, a rough idea, or a "we need something that can do X" — and they come back with a flying prototype, not a slide deck explaining why it's hard. This role exists for the person who's been building things in a garage, a workshop, or a shed for years because they couldn't not — and who's ready to point that obsession at Europe's defence capability instead of the next hobby build.  RESPONSIBILITIES * Take a concept from clean sheet to flying hardware — concept, design, fabrication, integration, first flight — with minimal hand-holding. * Set the technical approach when working across disciplines, and resolve design conflicts directly instead of escalating them. * Run field flight test campaigns: own the go/no-go call, diagnose failures fast, and decide whether it's a fix or a redesign. * Turn "I just know how to do this" knowledge into documentation other engineers can actually build from. * Unblock and mentor junior and mid-level engineers in design reviews and builds — no management title required. * Flag technical, schedule, or process risk before anyone asks — silence isn't a strategy here. * Iterate fast on field and test data without waiting for a retro to tell you what broke. QUALIFICATIONS * A track record of owning a full build cycle — concept to flight-tested prototype — independently, on at least one UAV/UGV or comparable platform. * Deep, hands-on experience with composites, mechanical assemblies, robotics, and embedded hardware — earned in a workshop, not from a manual. * Sound judgment under ambiguity and time pressure: you know what's good-enough-to-test versus good-enough-to-deploy without being told. * Strong independent root-cause diagnosis — you can stare at a cracked airframe or a bad flight log and get to a fix without senior sign-off. * Experience working across engineering disciplines and resolving competing technical requirements yourself. * A demonstrated instinct for mentoring or technically leading others, even informally. * A portfolio that proves it: personal builds, competition entries, workshop projects — anything that shows you've been engineering as a calling, not just a job, during and after hours. NICE TO HAVE * Active A2/A3 drone pilot certification or equivalent national licence. * CAD fluency (Fusion 360, SolidWorks) strong enough to set standards for others, not just finish your own files. * Debugging-level familiarity with flight controller ecosystems (PX4, ArduPilot, Betaflight) — not just configuration. * Fixed-wing experience, not just multirotor. * A background in competition, motorsport, or maker culture that grew into leading a build or owning a program end-to-end. If you´re interested in building the future of European Defence with us, and you see yourself reflected on the description above, please send us your  Portfolio & CV in English. We´re looking forward to meeting you!
