• Hybrid role currently working on site a minimum of 3 days per week with 2 days allowed for home based working but subject to change throughout the contract term.

MINIMUM QUALIFICATIONS:

1. Bachelor’s Degree in Aerospace, Aeronautical or Mechanical Engineering (or equivalent).
2. Minimum of five (5) years’ relevant experience in aircraft structures/stress, with demonstrable recent experience in modification substantiation (preferably interiors).

SKILLS / EXPERIENCE:

• Recent experience working with an EASA Part 21J Design Organisation (or equivalent) is highly desirable.
• Substantial knowledge of aircraft interior modification practices, installations and interfaces; familiarity with primary and secondary aircraft structures related to interior modifications.
• Proficient with hand calculations using classical stress analysis techniques and able to justify assumptions clearly.
• Proficient in Finite Element Analysis (FEA) tools and able to produce traceable models and results.
• Strong technical report writing skills with experience producing certification-ready substantiation packages.
• Working knowledge of EASA and FAA airworthiness requirements relevant to stress/structures (e.g., CS-25, FAR 25, ETSO/JTSO where applicable).
• High attention to detail, professional integrity and ability to work to contractual schedules.
• Ability to manage multiple programmes concurrently, prioritise workloads and adapt to changing project demands.
• Excellent communication skills for technical engagement with internal and external stakeholders.

ABOUT YOU:
