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

How to apply

Examples of CAD work or your own RC or UAV projects are welcome. No formal cover letter needed. We review applications on an ongoing basis.

Location: Stora Höga, Stenungsund Employment type: Full-time, on-site
