System Engineer

About Us Harmattan AI is a next-generation defense prime building autonomous and scalable defense systems. Following the close of a $200M Series B, valuing the company at $1.4 billion, we are expanding our teams and capabilities to deliver mission-critical systems to allied forces. Our work is guided by clear values: building technologies with real-world impact, pursuing excellence in everything we do, setting ambitious goals, and taking on the hardest technical challenges. We operate in a demanding environment where rigor, ownership, and execution are expected. About the Role As a System Engineer , you will own the architecture, system definition and implementation of one of our robotic systems — from concept to field deployment. You will work hand-in-hand with project managers and technical leads to translate mission needs into system-level designs, coordinate multidisciplinary engineering teams, and ensure overall system performance, robustness, and reliability. Responsibilities System Architecture : Transform system requirements into architectures solutions. Technical Coordination : Lead cross-functional design across mechanical, electrical, software, GNC, and ML teams. Trade-Off & Design Analysis : Conduct feasibility studies, trade-off analyses, and system-level simulations to guide technical choices. Integration & Validation : Oversee system integration, prototyping, and validation, ensuring performance targets are achieved. System Reviews : Drive design and architecture reviews, maintaining consistency between requirements, design, and testing. Continuous Improvement : Implement processes to enhance requirements traceability, system documentation, and validation workflows. Candidate Requirements 5+ years of experience in system engineering within robotics, aerospace, or defense sectors. MSc in Engineering (any field); PhD is a plus. Proven experience leading full system lifecycles (concept → prototype → validation). Strong background in system architecture, requirements engineering, and trade-off analysis. Broad engineering culture with understanding of mechanical, electrical, and embedded systems. Experience coordinating multi-disciplinary teams and managing technical interfaces. Rigorous, structured, and mission-driven mindset with strong analytical skills. Excellent communication and documentation abilities. Bonus: Experience with UAS or defense systems. We look forward to hearing how you can help shape the future of autonomous defense systems at Harmattan AI. Find more English Speaking Jobs in Switzerland on Arbeitnow
