Mechanical Engineer

Build the hardware, own the platform

At Frost Unmanned, you will be the engineer who turns our fixed-wing UAV from a design into a rugged, field-ready product. You will own the mechanical side of the platform: the structure, the component layout, the integration, and how it performs and holds up in real operations. You will have real influence over design decisions from day one.

Frost Unmanned develops sovereign unmanned systems for defense and government customers: high-speed fixed-wing strike UAVs and unmanned surface vessels for maritime and coastal operations. We are a small team in Stora Höga, Stenungsund, moving from development into serial delivery.

What you will do



Lead CAD design of airframe structures, mechanical assemblies, and component layouts



Set the aerodynamic and structural requirements for the platform, and work with our external simulation partners to verify their results



Turn simulation data into design decisions on strength, weight, performance, and manufacturability



Select, source, and integrate components and subsystems such as propulsion, fuel systems, and payloads.



Design for the end user: how the system is unpacked, assembled, and made ready in the field



Own the mechanical interface between the UAV and our pneumatic launcher



Support mechanical work on our USV platform



Take designs through prototyping, testing, and production, with drawings and documentation for our subcontractors

What we are looking for



Degree in Mechanical or Aerospace Engineering, or equivalent experience



Several years of hands-on mechanical engineering, ideally with UAVs, aircraft, or other high-performance systems



Strong CAD skills for lightweight structures and complex assemblies. This is the most important skill for the role



Enough understanding of aerodynamics and structural loads to set requirements and challenge simulation results



Experience taking designs from prototype to production



Eligible to pass Swedish security vetting

It is a plus if you have



Experience from defense or aerospace



Worked with fuel systems, propulsion, or air intakes



Composite materials and lightweight manufacturing



Built and flown your own RC planes, UAVs, or drones



Worked with launch systems, boats, or similar integration tasks

Why join us



Real ownership of a flying platform, not a small part of a large program



Short decision paths and direct access to company leadership



Work that goes from your CAD model to the field, fast



A small team where everyone works on site, together, every day



Competitive conditions and room to grow as the company scales
