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 an Lead RF Engineer - Electronic Warfare, you will own the delivery of our electronic warfare and signal intelligence 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. The capability to detect, investigate, and exploit system vulnerabilities. Responsibilities - Electronic Warfare Team: Build, maintain and manage a cross disciplinary Electronic Warfare Engineering Team. - Electronic Warfare Systems and Technology watch: Drive architecture and implementation of Electronic Warfare Systems. Ensure state of the art knowledge in EW/SIGINT. - 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 - 10+ years of experience in RF system engineering of Radio/Radar/GNSS and other Sensors within robotics, aerospace, or defense sectors. - Experience in Technology leadership in EW/SIGINT is a strong plus - Experience in Team leadership is a bonus, but not required - MSc in Engineering; PhD is a plus. - Proven experience leading full system lifecycles (concept → prototype → validation). - Strong background in RF, GNSS and Radar system architecture, requirements engineering, and system level trade-off analysis. - RF Signal Intelligence gathering and analysis for classification and AI training. - 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. We look forward to hearing how you can help shape the future of autonomous defense systems at Harmattan AI.
