Mechanical Design Engineer

Mechanical Design Engineer Apply now About the Role We are seeking a Mechanical Design Engineer to support the development of missile hardware and critical system components. In this role, you will define functional and mechanical interfaces, drive integration, and ensure that every design meets rigorous specifications throughout the entire product life cycle. At Frankenburg, you will join an exceptional team bringing together top engineering and defence expertise from across Europe. You will have the opportunity to shape system-level architecture and take full ownership of mechanical designs — from early concept to final delivery. Collaborating across disciplines, you will tackle integration challenges, optimize designs for manufacturability, and ensure the highest standards of reliability, safety, and traceability. Key Responsibilities Own end-to-end mechanical design of missile structures and subsystems, ensuring compliance with performance, weight, durability, and manufacturability requirements. Collaborate with teams across propulsion, GNC, avionics, and payload to manage mechanical interfaces effectively. Conduct formal design reviews, assess alternative solutions, and ensure that all designs meet specified requirements. Generate and maintain interface control documents and configuration baselines throughout the development life cycle. Manage and coordinate subcontracted mechanical work, review deliverables for alignment with specifications and quality standards. We Would Love You to Have Educational Background Bachelors' degree or higher in Mechanical or Aerospace Engineering, or a related field. Experience At least 3 years of experience designing complex mechanical systems within the aerospace, UAV, defence, space, or related industries. Technical Skills Proficient in CAD and peripheral configuration management systems. Soft Skills Solution-oriented mindset, excellent communication, and keen attention to detail. Able to perform with minimal support staff, rolling up your sleeves when needed. Mission Alignment Strong alignment with our mission to build affordable and mass-manufacturable defence technologies — ensuring every euro spent moves us closer to our goal. Security Clearance Willingness to undergo a background check as a condition of employment. Open to Relocate Willingness to relocate to Riga. Our Values Our mission is ambitious, and it takes a team that works with the same intensity. Own the Mission: Mission first. Always. We choose impact — we focus on what moves the mission forward fastest instead of “nice-to-haves". We fix it now — when delays or problems appear, we step up, rally the right people, and solve them immediately. We keep momentum — when time matters, we stay focused and move forward without waiting for perfect conditions. Strive for More: Dare more. Do more. Achieve the impossible. We challenge the status quo — we question, test, and improve instead of accepting “the usual way.” We embrace discomfort — we step outside comfort zones and turn challenges into growth. We anticipate the future — we build solutions that scale and set higher standards each time. Build with Trust: Be open. Keep promises. We walk the talk — what we say, we do. No excuses, no exceptions. We share openly — we communicate clearly and early, even when the news is hard. We own outcomes — we admit errors quickly, fix them, and prevent them from repeating. Ready to Make a Real Impact? Apply now! The deadline is August 16, 2026, but we review applications and reach out to qualified candidates continuously. Department Engineering Role Mechanical Engineering Locations Riga, Latvia Remote status Hybrid About Frankenburg Technologies Group Frankenburg Technologies a is a European defence technology company building affordable, mass-manufacturable guided missile systems for modern air and missile defence. This is a demanding engineering and manufacturing challenge. Guided missile systems must be precise, reliable and safe to operate, while also being affordable enough to use against mass aerial threats and producible in quantity. Frankenburg's first system, Mark I, is a guided interceptor missile, designed to defeat unmanned aerial systems, including drone swarms, at close range. Alongside missile development, Frankenburg is building the factories, supply chains and production processes needed to produce missiles in quantity and replenish them quickly. Headquartered in Tallinn, Estonia, Frankenburg operates in Latvia, the United Kingdom and Germany, with further European presence in Lithuania, Poland and Denmark. Join us in building the world’s next missile house.
