Mechanical Stress Engineer - Aircraft Interiors

We''re supporting a leading global aerospace engineering organisation in the search for an experienced Mechanical Stress Engineer to join its aircraft modifications team on a long-term contract basis.

This role centres on delivering structural substantiation for commercial aircraft interior modification programmes, producing certification-ready stress reports and supporting projects from concept through to approval. Working within a highly regulated aerospace environment, you''ll collaborate with multidisciplinary engineering teams to ensure compliance with EASA and FAA airworthiness requirements.

If you have a strong background in aircraft structures and certification, this is an opportunity to work on technically challenging programmes with long-term contract stability.

The Role
You''ll be responsible for delivering structural substantiation for a wide range of aircraft cabin modification programmes, including:

• Seating installations
• Galleys, lavatories and monuments
• Passenger Service Units (PSUs)
• Cabin reconfigurations and LOPA changes
• LRU installations
• Interior structural interfaces
• Associated structural modifications where required

Working alongside structures, design and certification engineers, you''ll produce high-quality engineering documentation to support certification activities across multiple programmes.

Key Responsibilities

• Produce structural substantiation reports for aircraft modification programmes.
• Perform classical hand stress calculations and Finite Element Analysis (FEA).
• Generate certification-ready stress reports and supporting technical documentation.
• Produce load cases, assumptions records and compliance documentation.
• Support design reviews and certification activities.
• Work collaboratively with multidisciplinary engineering teams across international programmes.
• Ensure documentation is fully traceable and suitable for regulatory approval.
• Deliver multiple engineering work packages to agreed programme milestones.

What We''re Looking For

• Degree in Aerospace, Mechanical or Aeronautical Engineering.
• Minimum of five years'' experience in aircraft stress or structures engineering.
• Proven experience producing structural substantiation for aircraft modifications.
• Strong understanding of aircraft cabin interiors and structural interfaces.
• Excellent classical stress analysis and hand calculation capability.
• Experience using Finite Element Analysis (FEA).
• Strong technical report writing skills.
• Working knowledge of EASA and/or FAA certification requirements, including CS-25 and FAR 25.
• Previous experience within an EASA Part 21J Design Organisation is highly desirable.

What''s On Offer

• £53.00-£64.50 per hour (Umbrella)
• Long-term contract with strong potential for extension
• Hybrid working (currently 3 days on site / 2 days from home)
• Opportunity to work on high-profile commercial aircraft modification programmes
• Collaborative international engineering environment
• Immediate start available

If you''re an experienced Aircraft Stress Engineer looking for your next contract and have a track record of delivering certification-ready structural substantiation within the aerospace sector, we''d love to hear from you.
