Check you match the skill requirements for this role, as well as associated experience, then apply with your CV below.

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 Role As 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 Responsibilities Structural 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 Arrangements This 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. xwzovoh

----------------------------------------
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
