Harmattan AI

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 Architect, you will own the end-to-end architecture, system definition, and strategic implementation for our entire portfolio of robotic systems, from long-term vision to field deployment, collaborating closely with executive leadership and technical leads, and forming a critical partnership with the Product Manager to ensure efficiency; this pivotal role drives strategic programs like Anti-drone warfare, ISR and strike systems, Equipment fusion (especially aeronautics), or C2 and IA. Responsibilities * System-of-Systems Design & Strategy: Translate complex strategic goals into global, system-of-systems designs, defining and championing the overall system architecture strategy across the enterprise. * Architectural Sizing & Verification: Ensure all systems meet defined needs and are correctly sized through rigorous verification of scope, complex system-of-systems simulations, and precise system sizing, guiding major technical investments. * Coordination and Technical Leadership: Coordinate large multidisciplinary engineering organizations, providing overarching technical leadership across cross-functional design efforts (mechanical, electrical, software, GNC, ML, product), ensuring long-term performance, robustness, and strategic reliability across the enterprise. * Specification & Integration Governance: Govern system integration standards and validation processes, contributing to the complex process of specification management by ensuring all architectural prerequisites are met and driving multi-system architecture reviews for enterprise design consistency. * Continuous Improvement: Implement and institutionalize processes to enhance requirements traceability, system documentation standards, and validation workflows across the entire engineering organization. Candidate Requirements * 10+ years of experience in system engineering or architecture, with significant time in a senior or lead role. * MSc in Engineering (any field); PhD is a plus. * Specific Domain: Experience in the defense sector is mandatory, and drones are a big plus. * Strong knowledge in one of those specializations: * C2 (Command and Control) & AI * ISR (Intelligence, Surveillance, and Reconnaissance) * Strike UAV, loitering munitions * Anti-drone warfare * UAV equipments & fusion * Expert in defining and leading the full lifecycle of complex, multi-system and system-of-systems architectures. * Strategic, analytical, and mission-driven with expertise in strategic requirements engineering and high-level trade-off analysis. * Deep engineering understanding across mechanical, electrical, embedded, and enterprise software systems. * Experience coordinating large, multi-disciplinary engineering organizations and managing complex technical/strategic interfaces. * Exceptional communication, presentation, and technical documentation skills for both technical and executive audiences. We look forward to hearing how you can help shape the future of autonomous defense systems at Harmattan AI.

Alice & Bob

Alice & Bob is developing the first universal, fault-tolerant quantum computer to solve the world’s hardest problems. The quantum computer we envision building is based on a new kind of superconducting qubit: the Schrödinger cat qubit. In comparison to other superconducting platforms, cat qubits have the astonishing ability to implement quantum error correction autonomously! We are at the forefront of the quantum race, competing with tech giants such as Google or IBM, and we are growing fast after securing  €100 million of funding in 2025 to develop our unique technology. Currently 200+ and counting, between physicists, PhD students, engineers and experienced business professionals, we are united to reach our ambitious goal. Are you a quantum pioneer? Join us on a mission to reshape the future!   About the role The Performance Optimization (PoP) team aims at using advanced ML & Optimization tools on all the lifecycle of a quantum chip: design, simulation, calibration, operation, error correction. You will be joining a passionate and focused team within an amazing organisation dedicated to build a universal and fault-tolerant quantum computer without taking any detours.   As an Experimental Quantum Physicist on the PoP team, you will drive the innovation and improvement of our cat-qubit processors. You'll measure, characterize, and optimize our quantum circuits, while also enhancing our experimental tools and setup. Your role involves integrating machine learning and optimization into our hardware design and collaborating with internal teams to advance our company's experimental roadmap.
