Mechanical Engineer

Frost Unmanned AB; Stenungsunds kommun; On-site; SEK 900,000 - 1,300,000; Full time

Job summary

Frost Unmanned AB in Sweden is seeking an engineer to turn our fixed-wing UAV from design into a rugged, field-ready product. You will own the mechanical side of the platform, shaping structure, layout, integration, and durability in real operations.

Join a small, on-site team in Stora Höga, Stenungsund, moving from R&D into serial delivery. You will guide CAD design, define aero-structural requirements, and translate simulation results into robust, manufacturable solutions.

Qualifications

• Degree in Mechanical or Aerospace Engineering.
• Hands-on mechanical engineering experience, ideally with UAVs or high-performance systems.
• Strong CAD skills for lightweight structures and complex assemblies.
• Some understanding of aerodynamics and structural loads to set requirements.
• Experience taking designs from prototype to production.
• Eligible to pass Swedish security vetting.

Responsibilities

• Lead CAD design of airframe structures, mechanical assemblies, and component layouts.
• Set aerodynamic and structural requirements for the platform and verify results with external simulation partners.
• Turn simulation data into design decisions on strength, weight, performance, and manufacturability.
• Select, source, and integrate propulsion, fuel systems, and payloads.
• Design for the end user: unpacking, assembly, and field readiness.
• Own the mechanical interface between the UAV and the pneumatic launcher.
• Support mechanical work on the USV platform.
• Take designs through prototyping, testing, and production with documentation for subcontractors.

Job description

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

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

Frost Unmanned is an equal opportunity employer. We welcome applicants regardless of gender, ethnicity, age, disability, sexual orientation, or background.
