Milton Keynes / Global
We’re looking for a Structural Analysis Engineer to work on advanced UAV airframes, focusing on lightweight structures, composites, and full airframe structural integrity.
This role is ideal for someone who wants real ownership, works comfortably across disciplines, and enjoys early-stage aircraft development.
What you’ll work on
Define and analyse airframe load cases (maneuvre, gust, landing, propulsion, inertial)
Perform global and local FEA on wings, centre bodies, booms, mounts, and joints
Conduct stress, deflection, stiffness, and buckling analysis
Carry out composite laminate and sandwich panel analysis
Evaluate margins of safety and reserve factors
Support fatigue, durability, and damage tolerance assessments (concept–preliminary level)
Perform modal and vibration analysis to avoid resonance issues
Support thermal–structural effects from motors, batteries, and environment
Work closely with design, aero, performance, and systems teams to influence structure early
Support structural optimisation for weight vs strength
Contribute to test correlation and design iteration
Produce clear, review-ready analysis documentation
What we’re looking for
Degree in Aerospace / Mechanical Engineering (or similar)
Strong fundamentals in aircraft structures
Hands‑on experience with FEA tools (ANSYS, Abaqus, NASTRAN, etc.)
Understanding of composite structures and lightweight design
Comfortable working with CAD geometry and evolving designs
Able to think beyond tools and apply engineering judgement
Nice to have
Experience with UAVs or small aircraft
Exposure to composites manufacturing or testing
Experience working on early‑stage aerospace programmes
Why join us
High technical ownership
Work across the full design lifecycle
Small, sharp engineering team
Real engineering problems, not siloed tasks
It is mandatory for the candidate to hold a valid UK visa for this role.
We do not provide visa sponsorship for this position.
