Martin Audio Ltd. - Loudspeaker Development Engineer

Posted On: 2018-4-9
Location: High Wycombe, UK

The Company:

Martin Audio enjoys an international reputation for supplying award winning professional loudspeaker systems across the spectrum of touring, theatre and installation applications.
The company was founded in 1971 by engineering maestro Dave Martin. His vision was to enable bands to play to larger audiences and be properly heard for the first time. The reputation of Martin Audio speakers quickly grew and soon we were producing world class touring systems for the super groups of the day, including Pink Floyd, The Who and Supertramp.
Renowned for integrity in design, technical excellence and the longevity of its products, Martin Audio takes system creation into a further dimension. Our mission is for every member of the audience to enjoy an exceptional sonic experience faithfully reproducing the artist’s performance.

Location:

The company's prestigious UK headquarters at High Wycombe houses dedicated research & development facilities, manufacturing processes, demonstration suite, warehousing, management, sales and customer support offices.


General Position Summary:

• A creative and highly motivated professional loudspeaker designer responsible for the design of loudspeaker systems that meet the design specification having ownership of projects from concept through to manufacture.
• You will collaborate closely with the cross-functional development team meeting required milestones and delivering best in class product designs to market on time and to target cost.


Essential Functions and Major Responsibilities:

• Design of Loudspeaker Systems to Meet Design Specification.


Technical

o A thorough understanding of loudspeaker transducers and systems is required in order to design world class systems.
o Transducer specification, selection and evaluation.
 Excellent knowledge and understanding of lumped parameters.
 An understanding of non-linear parameter measurement and their interpretation.
 The ability and aptitude to critically assess practical issues and apply your knowledge of transducers to meet performance and cost specifications.
o Enclosure specification, prototyping, measurement and evaluation
 Fluent in the use of modelling software for low frequency design.
 A rudimentary understanding of modelling software including BeM, FeM and their application to system design.
 Knowledge and practical use of 3D CAD (Ideally Creo), in order to interpret existing CAD and to design, model and analyse Concepts.
