Job Requirements
We are seeking an experienced Aero Gas Turbine Drawing Checker who holds current OEM-delegated checking approval. The successful candidate will provide independent technical assurance of engineering drawings and associated product definition data before release, ensuring that design intent, safety, quality, configuration, and manufacturability requirements are fully satisfied.
This is a senior technical role for a checker who can operate with minimal supervision, exercise delegated authority within its defined scope and complexity, and work effectively with design, manufacturing, stress, materials, quality, and configuration-management teams.
Applications are welcomed from candidates seeking permanent or contract engagement, subject to business requirements. Eligibility to apply: the role includes Defence work, and as such requires eligibility for UK SC security clearance (i.e., UK citizen or 5 years continuous residency in the UK). Foreign nationals without 5 years UK residency are not eligible to apply for this position.
Key Responsibilities
- Independently check aero gas turbine component, assembly, installation, and interface drawings in accordance with applicable OEM procedures, engineering standards, and delegated authority requirements.
- Verify design intent, dimensional completeness, datum strategies, tolerance schemes, GD&T, limits and fits, materials, processes, surface treatments, notes, and drawing conventions.
- Confirm consistency between 3D CAD models, 2D drawings, bills of material, specifications, interface data, and product lifecycle management records.
- Assess drawings for clarity, producibility, inspectability, assembly, maintainability, and avoidance of ambiguity or conflicting requirements.
- Review tolerance stacks and interface conditions, challenging assumptions where necessary, and ensuring that functional requirements are protected.
- Identify errors, omissions, and technical risks; record clear findings and work with authors to achieve right-first-time closure.
- Apply OEM delegated approval only within the authorized commodity, project, product, complexity, and release scope.
- Maintain full compliance with configuration control, change management, data security, export control, and quality management requirements.
- Support drawing releases, engineering changes, design reviews, audits, concessions, and investigations where drawing interpretation is required.
- Provide technical coaching to designers and developing checkers, sharing lessons learned and recurring defect themes.
- Contribute to checker guidance, checklists, drawing audits, capability development, and continuous improvement activity.
- Escalate matters outside delegated scope or technical competence to the appropriate OEM authority.

Work Experience
Essential Qualifications and Experience
- Current OEM-delegated drawing checking approval for aero gas turbine product definition; applicants must clearly state the OEM, product or commodity scope, permitted complexity, and expiry or review status.
- Substantial experience in gas turbine mechanical design, detailing, and drawing checking, normally gained over at least five years within the relevant OEM environment.
- Proven checking experience on one or more aero-engine commodities such as turbines, compressors, structures, and transmissions, rotatives, casings, externals, installations, pipework, or control-system hardware.
- Expert knowledge of engineering drawing principles, GD&T, datum systems, tolerance analysis, limits and fits, manufacturing methods, and inspection requirements.
- Strong working knowledge of the applicable OEM design and drawing standards, release procedures, and delegated authority governance.
- Experience using relevant 3D CAD and PLM/PDM systems, such as Siemens NX and Teamcenter, or equivalent OEM toolsets.
- Ability to interpret design requirements, specifications, change documentation, and interface definitions and to make sound, auditable technical judgements.
- High level of accuracy, attention to detail, and personal accountability, supported by clear written and verbal communication.
- Degree, HNC/HND, or equivalent qualification in mechanical, aerospace, aeronautical, or manufacturing engineering, or demonstrable equivalent industry experience.

Desirable Experience
- Delegated checking approval across multiple aero-engine commodities, projects, or complexity levels.
- Experience of drawing release authority, technical review, design approval, or supplier technical review.
- Knowledge of ASME Y14.5 and aerospace quality management requirements, including AS9100 principles.
- Experience checking legacy-to-digital conversions, model-based definition, complex castings, forgings, machined parts, or installation definitions.
- Background in design for manufacture and assembly, non-conformance resolution, root cause analysis, or zero defect improvement.
- Experience mentoring prospective delegated checkers or supporting formal checker assessments and audits.
Delegated Approval Requirements
Appointment is subject to verification of the candidate’s delegated authority and competence record. Delegation is not assumed to transfer automatically between OEM programmes, component groups, or complexity levels. Where required, the successful candidate must complete the OEM’s read-across, reassessment, or local authorisation process before exercising approval authority.
What We Offer
- A technically influential role supporting advanced aero-engine programmes.
- The opportunity to work within a multidisciplinary engineering environment and strengthen delegated technical capability.
- A competitive package appropriate to experience and approval scope.
- Professional development through exposure to complex product-definition, quality, and continuous-improvement challenges.
