ABOUT THE ROLE As Electrical System Architect, you will be responsible for defining and developing the electrical system architecture across complex vehicle systems. You will work closely with hardware, software, and system teams to ensure seamless integration across ECUs, communication networks, and electrical components. 👉 The role is hands-on and technical, with a focus on: * Electrical architecture * Hardware systems * Integration and system design KEY RESPONSIBILITIES * Define and develop electrical system architecture for low voltage automotive systems * Drive system design across ECUs, communication networks, and hardware components * Translate and break down system and customer requirements into technical solutions * Ensure scalability, performance, and robustness of electrical systems * Work closely with hardware developers, software teams, and system specialists * Handle technical challenges such as: * EMC * signal integrity * load balancing * network topology * Ensure compliance with standards such as ISO 26262 and cybersecurity requirements * Support industrialization from concept to production REQUIREMENTS * Master’s degree in Electrical Engineering, Automotive Engineering, or similar * Solid experience in electrical system architecture within automotive * Strong background in low voltage systems and hardware design * Deep understanding of: * ECUs * communication protocols (CAN, LIN, etc.) * electrical system integration * Experience with: * AUTOSAR * ISO 26262 * EMC considerations * Experience working cross-functionally with hardware and software teams IMPORTANT FOR THIS ROLE * This is a technical architect role – not a project manager position * Strong hands-on hardware and system design experience is required * Focus is on low voltage electrical systems, not high-level program management MERITORIOUS * Experience from Volvo Cars, Volvo Group or Geely * Experience within electrified powertrain systems (inverters, EDUs, etc.) * Background in power electronics

🚀 JOIN SE3 LABS AS DRONE TEST & FIELD ENGINEER Help us get our autonomous systems airborne and pushed to their limits. Turn advanced designs into robust, field-proven, real-world solutions. Early team, deep tech, high impact. ABOUT SE3 SE3 Labs is building Spatial AI by combining 3D computer vision with large language models (LLMs). We believe the ability to reason about and act within physical space is foundational to unlocking the next generation of automation, from construction to smart infrastructure, and ultimately, defense. Now, we’re building the physical platform to bring Spatial AI to life. That means high-performance, real-world robotic systems (starting with UAVs) and we’re looking for a hands-on operator who’s ready to fly, demonstrate and perfect these machines with us. ABOUT THE ROLE As our Drone Test & Field Engineer, you’ll play a key role in getting and keeping our fleet of autonomous drones in the air. Working as part of our development team, you will bring new drones to life where hardware and software come together and test their capabilities systematically in the real world. Your contribution will determine how well we understand our technology and define the path of our future development. WHAT YOU’LL WORK ON * Integrate & Checkout: Work hand-in-hand with our hardware & software developers and technicians to complete integration and get new UAVs to flight readiness. * Launch and Fly: Operate and fine-tune drones from backpackable quadcopters to three meter wingspan fixed-wings (eVTOL & catapult launch). * Test Strategy: You own qualification and development flight testing, from structure and organization over execution in the field to data processing and documentation. * Improve & Suggest: Spot bugs and design flaws, propose & evaluate improvements, and help us move faster and build better. * Demonstrate & Train: Introduce our systems to partners and end users on our test-base and in the field across Europe. YOUR PROFILE * You’ve completed a Bachelors in Aerospace Engineering, Robotics or another relevant technical field * You bring hands-on experience assembling, tuning and operating drones: 3+ years professionally or equivalent in racing / competition / enthusiast projects * You are intimate with Q Ground Control, Ardupilot or PX4 * You bring a responsible and structured approach to mission-planning, airspace coordination, etc. * You’re skilled in troubleshooting drones and electronics * You care about precision, quality and a systematic problem-solving approach * You are proactive, willing to improvise and have a strong sense of ownership * Conversational English is a must; German is a strong plus * Driving license class B, BE is a plus ESPECIALLY VALUED BONUS SKILLS * Data analysis skills (log interpretation, root cause-, frequency domain analysis) * You are familiar with using a command line and basic scripting * Experience running environmental tests like vibration, EMI or thermal, ideally MIL-Spec * Regulatory experience (EASA SORA or similar frameworks) * Good understanding of sensors, signal chains, and testing setups * Familiarity with CAD and 3D printing * Completed military basic training and/or understanding of army processes PERKS & BENEFITS * Make your passion your job: If you love drones, you will relish this role * AI-boosted workplace: We empower every employee with best-in-class AI tools and agents, giving you unlimited access to the latest advancements and a true productivity edge * Real Ownership: Get early, real stock options to participate directly in SE3’s growth * 31 Paid Days Off: 30 vacation days plus your birthday off * Well-being Access: Free membership to gyms, yoga, and wellness through EGYM Wellpass * Team Offsites: We go on 2 company retreats per year, our last ones were in Italy, Greece and Spain * Mentorship: Work closely with experienced engineers and get paired with a professional mentor to support your growth OUR PROCESS 1. Intro Call (20 min): Let’s get to know each other (conducted by our Talent Team) 2. Technical Interview (45 min): We dive deeper into your technical experience and problem-solving (with Francisco, our Founding Drone Engineer) 3. Onsite Trial/Case (2 hrs): We’ll test and troubleshoot something together, just like on the job (together with our Hardware Team) 4. Team Dinner/Lunch: See if it’s a culture fit on both sides (can be integrated into the Onsite to accommodate long journeys)
