Senior Mechanical Engineer, UAV Systems

Job Description: Frost Unmanned develops sovereign, resilient unmanned systems for defense and government missions. We specialize in high-speed, mid- and long-range fixed-wing strike UAVs as well as USV platforms, all designed for real operational needs in maritime and coastal environments. We are now looking for a Senior Mechanical Engineer with strong hands-on experience in lightweight structures and CAD to join our team in Stora Höga. You will play a central role in the redesign of our current fixed-wing strike UAV platform and upcoming development projects. You will also contribute to our pneumatic UAV launcher and potential USV-related mechanical systems. This is a full-time, on-site position in Stora Höga where practical engineering skills directly impact our products in a fast-paced, agile environment. We believe that great engineering outcomes come from close collaboration, just like no football team ever won a championship by practicing alone on remote fields, success here comes from working together on the pitch every day. Your main responsibilities will include:

Lead and perform detailed CAD design of lightweight structures, airframes, wings, fuselage, and mechanical assemblies using Fusion 360

Optimize designs for strength, weight, manufacturability, and high-speed performance

Conduct simulations including structural analysis (FEA), fluid dynamics, and other relevant studies to validate and improve designs

Take concepts through design for manufacturing, prototype building, testing, and production support

Manage mechanical integration of subsystems, payload bays, propulsion, and mechanisms such as the pneumatic launcher

Prepare design reviews, assembly instructions, drawings, and documentation for internal use or subcontractors

Solve complex engineering challenges under tight schedules and evolving requirements

We are looking for a candidate with real-life experience in the following areas:

Advanced CAD modeling, with strong proficiency in Fusion 360 for lightweight structures and complex assemblies, this is the most important skill

Practical work with RC planes, UAVs, or drones, including building, testing, and iterating on flying platforms

Design for manufacturing and composite manufacturing processes

Lightweight structure design and optimization for aerospace or high-performance applications

Aerodynamics understanding and fluid dynamics simulations (CFD)

Structural simulations and analysis to ensure reliability under flight loads

Hands-on mechanical engineering, prototyping, and problem-solving in dynamic project settings

Must-have qualifications:

BSc or MSc in Mechanical Engineering, Aerospace Engineering, or equivalent

At least 5 years of relevant experience in mechanical design, preferably within UAVs, drones, or similar high-performance systems

Proven track record with CAD of lightweight structures and production-grade detailing

Ability to work independently as well as in a small, agile team

It is a big advantage if you also have:

Experience from the defense or aerospace industry

Knowledge of high-speed fixed-wing aerodynamics and related challenges

Familiarity with composite materials and lightweight manufacturing techniques

Previous work with launch systems, USVs, or similar mechanical integration tasks

We value a practical, solution-oriented mindset and the ability to deliver under real-world constraints. If you have built and flown your own RC or UAV projects, that kind of experience is highly appreciated.
