Our client, a leading organisation within the defence and advanced manufacturing sectors, is seeking a Senior Test & Development Engineer to support the design, development and validation of high-integrity gearbox products. This permanent, full-time role will focus on test rig development, product performance testing, verification and validation, and the delivery of technical test systems for complex mechanical products.

• Define product validation, verification and performance test requirements.
• Develop test plans, specifications and acceptance criteria for gearbox products.
• Specify test equipment, instrumentation, data capture systems and calibration requirements.
• Design, set up and commission test rigs, including guarding, lubrication and cooling systems.
• Conduct data capture, processing, analysis and presentation of test results.
• Carry out vibration, noise, torque, pressure, temperature, flow and displacement measurement activities.
• Provide technical oversight, troubleshooting and support throughout test programme execution.
• Support client witness testing, operational teams, service activities, design reviews and project bid proposals.
• Produce engineering solutions for test rig hardware requirements and maintain test data logs and documentation.
• Lead or contribute to DFMEA, PFMEA, structured problem-solving and continuous improvement activities.
• Liaise with engineering teams, clients and wider business functions to deliver project and customer requirements.

• Experience in verification, validation and testing of rotating equipment or complex mechanical products.
• Knowledge of product performance validation, test methodologies and certification requirements.
• Understanding of instrumentation and data capture systems, including measurement of displacement, torque, pressure, temperature and flow.
• Experience in vibration measurement and analysis, including in-situ shaft line and coupling balance assessment.
• Knowledge of electrical and hydraulic drive and control systems, equipment calibration and machinery safety regulations.
• Understanding of relevant industry standards, including ISO, AGMA, DIN, FKM and DNV.
• Awareness of functional safety, PLM and lifecycle management systems, ideally Teamcenter, together with SAP user experience.
• Knowledge of 2391 Test & Inspection principles would be advantageous.
• Experience of structured problem-solving methodologies such as 8D and DMAIC.
• Strong data-driven decision-making, report writing, presentation and communication skills.

• Level 5 Diploma with relevant engineering experience.
• A degree in Mechanical Engineering or a closely related discipline is preferred.

Experience within defence, on- and off-highway transmissions, internal combustion engines, turbo machinery or large-scale engineering design and manufacturing environments would be highly relevant. An understanding of gated and regulated design processes for complex mechanical systems would also be beneficial.

• Strong integrity and a professional, objective approach to conflict resolution.
• Ability to teach, mentor and support colleagues.
• Well-developed emotional intelligence and collaborative working skills.
• Organised and methodical approach to planning, documentation and test delivery.

This is a permanent, full-time position working Monday to Friday for 37.5 hours per week. During gearbox testing, participation in a 24/6 shift operation for up to six weeks may be required. Some domestic travel may be involved to support testing and service activities.
