Reporting To

Chief Mechanical Engineer

Job Purpose

 To design and develop underwater acoustic transducers to meet internal and external customer driven requirements and to ensure that transducer development is using the most up to date technology and adheres to external and Company quality standards.

Principal Responsibilities

  1. 1. To design and manage the development of underwater acoustic transducers to internal and external customer driven specifications from concept to pre-production.  To include acoustic analysis/simulation, material selection, coordination of prototype manufacture, design of experiments and transducer testing to specifications.

    2. To assume technical design responsibility for all transducer development.  To include creating and maintaining records of transducer designs, material suppliers, manufacturing techniques and procedures.  This may also include managing suppliers and specialist acoustic consultants.

    3. To develop and document design procedures and rules so as to protect and document Company knowledge. 

    4. To be responsible for the planning, execution and reporting of transducer testing activities, including the development of specialist jigs and fixtures as required.  To include supervision of the transducer development tank and responsibility for use of the associated test equipment.

    5. Promote new enabling technologies, innovative design concepts and methods for developing transducers with particular emphasis on polyurethane technology, wideband transducer design and 1-3 composites. 

    6. To develop and maintain knowledge of the latest techniques in subsea acoustic transducer design, analysis and manufacture and to distribute the latest technological and product advances to the relevant engineers to address emerging engineering needs.

    7. To develop a database of the design of complementary products and assess the potential for improvements to the Sonardyne product range.

    8. To gather knowledge from existing transducer experts within the company and then combined with own expertise disseminate the accumulated knowledge by mentoring / training the other transducer engineers within the company.

    9. To provide support for investigations into in-service transducer failures and to support with developing remedial solutions in a timely and cost effective manner.

    10. To provide technical input into bid proposals in the area of transducer design and review proposals for technical accuracy and associated risks.

    11. To produce and maintain project plans as required, provide weekly updates of workload, progress and issues to the Chief Mechanical Engineer.  Highlight areas of technical and/or commercial risk, report these to the Chief Mechanical Engineer and assist with actively managing any risks. 

    12. To present comprehensive material and time booking documentation for each project in accordance with the administrative guidelines of the Department and ISO/Company Quality policies and procedures.
