Mechanical Engineer

Design and size the composite airframe of a high-speed strike UAV
At Frost Unmanned, you will design the composite structure of our fixed-wing UAV in CAD and size it yourself, from first concept to a rugged, field-ready aircraft. You will own the airframe: wings, fuselage, load paths, joints and how it all comes apart and goes together in the field. 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. We are a small team in Stora Höga, Stenungsund, moving from development into serial delivery.
What you will do

Design airframe structures and assemblies in CAD, from concept to production drawings


Size composite structures yourself: laminate layup, ply orientation, joints and inserts, with hand calculations and first-pass FEA


Set structural and aerodynamic requirements, and review and challenge results from our external simulation partners


Design for manufacturing: moulds, layup, bonding and tolerances that subcontractors can build to


Integrate propulsion, fuel system, payload and the pneumatic launcher interface into the airframe, with control of weight and CG


Design for field assembly: fast, robust and doable in the cold with gloves on


Take designs through prototyping, testing and production


What we are looking for

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


Hands-on experience designing and sizing composite structures in real projects


Experience with aircraft, UAVs or other airframes, professionally or in serious own projects


Solid understanding of aerodynamic and structural loads


Degree in Aerospace or Mechanical Engineering, or equivalent experience


Eligible to pass Swedish security vetting


It is a plus if you have

Taken a composite structure from design to series production


Experience from defense or aerospace programs


Built and flown your own fixed-wing RC aircraft or UAVs


Worked with fuel systems, air intakes or launch systems


Why join us

Ownership of a complete airframe, not a small part of a large program


Your design goes from CAD to flight test in weeks, not years


Short decision paths and direct access to company leadership


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


Competitive conditions and room to grow as the company scales


How to apply
Send your CV and a few lines about an airframe or composite part you have designed. Portfolio and CAD examples are strongly encouraged. Shortlisted candidates will do a short paid CAD task. We welcome applicants from across the EU and review applications on an ongoing basis.
