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.
