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.
