Aerostructures Engineer, Fixed-Wing UAV
About the company
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.
Your tasks
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.
- 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
Requirements
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
What we offer
- 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.
