We build AI-guided interceptors to counter drones and cruise missiles, along with the software platform that powers them.\nOur customers are NATO-aligned militaries and defense institutions, and our systems are regularly deployed during live exercises and operational demonstrations across Europe, the Middle East, and Asia.\nFounded in 2024, we have grown to 90 people, raised over $60M, and increased revenue 40× this year. We are now entering a new phase of international expansion, industrial scaling, fundraising, and product development.\nAbout the Role\nWe are building next-generation interceptor drones and are looking for a Senior Jet Engine Design Engineer to lead the development of small-scale jet propulsion systems (12-25 kg thrust class), from concept to flight-ready hardware. This is a hands-on, high-ownership role in a fast-moving startup environment where speed and iteration matter more than lengthy upfront studies.\nResponsibilities:\nDesign and develop new small jet engines (12-25 kg thrust range) in-house, optimized for very low production cost\n\nOwn the aerodynamic design of turbine components, balancing performance, manufacturability, and cost\n\nDesign a large portion of the turbine for metal 3D printing (additive manufacturing), leveraging design-for-AM principles to reduce part count, weight, and cost\n\nWork closely with 3D printing operations to define printable geometries, tolerances, post-processing, and qualify parts for flight use\n\nDrive a rapid, fail-fast iteration process: build, test, learn, and redesign quickly rather than relying on long analytical phases before prototyping\n\nIntegrate propulsion systems into airframes such as flying wings and other interceptor drone configurations, working with aerostructures and systems teams\n\nApply and enforce design rules for operation in extreme environments (cold and hot climates, rain, humidity, icing conditions) to ensure engine reliability across the full operational envelope\n\nContribute to engine testing (bench and flight), performance validation, and continuous design improvement\n\nCandidate Profile:\nMinimum 8 years of experience in jet engine / gas turbine design, with a proven track record of having designed and delivered engine models (not just component-level work)\n\nStrong hands-on experience with small jet engines in the 12-25 kg thrust class\n\nSolid global understanding of jet engine architecture: compressor, combustor, turbine, fuel system, controls, and their interactions\n\nExperience designing turbine/engine components for metal additive manufacturing (DfAM), and practical knowledge of metal 3D printing processes and constraints\n\nComfortable working in a rapid-iteration, fail-fast development culture rather than a traditional long-cycle aerospace process\n\nExperience integrating propulsion systems into airframes (flying wing or similar unconventional platforms is a strong plus)\n\nKnowledge of design requirements for extreme operating environments (temperature extremes, precipitation, icing)\n\nAbility to work autonomously in a small, fast-paced startup team, wearing multiple hats when needed\n\nNice to Have\nExperience with UAV/drone propulsion specifically (vs. manned aviation)\n\nFamiliarity with low-cost manufacturing strategies for defense/dual-use hardware\n\nPrior startup or skunkworks experience","description_format":"text","description_chars":3371,"description_truncated":false,"requirements":{"experience_years_min":8,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Air
