Part 21J Design Engineer (Structures & Mechanical)
Any additional information you require for this job can be found in the below text Make sure to read thoroughly, then apply.
An exciting opportunity has arisen for a Part 21J Design Engineer to join a highly specialised aerospace engineering environment, supporting aircraft-level design within a Part 21 Design Organisation.
This is a design-led position, ideal for an engineer who enjoys owning structural solutions from concept through to certification, with the opportunity to progress towards Compliance Verification Engineer (CVE) status.
The RoleAs a Part 21J Design Engineer, you will take ownership of aircraft structural design activities, working across both new and in-service programmes. You will play a key role in delivering robust, certifiable solutions, whilst also carrying out independent technical checking to ensure the highest standards of engineering integrity.
Key ResponsibilitiesStructural Design
Own and deliver aircraft structural design solutions from concept through to detailed design and release
Produce high-quality engineering drawings, models, and supporting reports
Contribute to structural substantiation activities, including strength, fatigue, stiffness, and damage tolerance
Support design, modification, and repair work across metallic and composite structures
Collaborate with cross-functional teams including stress, systems, manufacturing, and airworthiness
Technical Checking
Carry out independent technical checking of design data, including drawings, models, and reports
Ensure outputs are compliant, consistent, and aligned with approved design methodologies
Provide constructive challenge in line with design assurance principles
Compliance & Development
Support certification and compliance activities through robust engineering design
Work towards CVE (Structures) authorisation, supported by the organisation
Contribute to maintaining high standards of design assurance and airworthiness compliance
About You
Degree qualified in Aerospace, Mechanical Engineering, or a related discipline (or equivalent experience)
Proven experience in aircraft-level structural design, not just component-level work
Strong background in producing and owning design data for certification purposes
Experience with structural substantiation and airworthiness requirements
Confident working within a regulated Part 21J environment (or similar)
Able to apply sound engineering judgement based on practical design experience
Desirable Experience
Previous CVE (Structures) authorisation
Experience working with the UK CAA and/or EASA
Knowledge of composite structures, fatigue, and damage tolerance
Experience across multiple aircraft platforms or modification programmes
Ability to mentor or support junior engineers
Working ArrangementsThis role is ideally office-based in South Wales, supporting collaboration and design integration. However, hybrid or flexible working options may be considered for the right individual. xsngvjr
Why Apply?
Flexible and Hybrid working
Work on complex, aircraft-level design projects
Clear pathway towards CVE authorisation
Join a highly technical and collaborative engineering environment
Opportunity to influence real-world aerospace design solutions
