Mechanical Development Engineer

As a Mechanical Development Engineer( Hydrophone Sensor) at Optics11, you contribute to the development and engineering realization of the hydrophone sensor subsystem throughout the product development lifecycle. You translate allocated product and subsystem requirements into robust engineering solutions while developing your technical expertise in underwater sensor technology.

The hydrophone sensor subsystem comprises the acoustic sensing element, mechanical housing, internal structural components, sealing concepts, and associated mechanical interfaces that enable reliable underwater sensing performance. Working as part of a multidisciplinary engineering team, you contribute to developing, improving, and maturing subsystem solutions that support successful product realization.

You work closely with Product System Engineering, Product Integration, Verification & Validation, Lifecycle Engineering, manufacturing partners, and other subsystem development teams to develop reliable hydrophone sensor solutions while continuously expanding your technical capability.

Key Responsibilities:

• Contribute to the development and realization of the hydrophone sensor subsystem throughout the product development lifecycle.

• Translate product and subsystem requirements into robust engineering solutions.

• Develop hydrophone sensor assemblies, mechanical housings, internal structures, sealing concepts, and subsystem interfaces.

• Produce detailed mechanical designs, engineering drawings, specifications, calculations, and design documentation.

• Develop prototypes and support subsystem integration, testing, and verification activities.

• Perform engineering analysis, characterization, and validation of hydrophone sensor assemblies.

• Support acoustic characterization and correlate engineering models with experimental results.

• Analyze engineering results, identify technical issues, and implement design improvements.

• Apply engineering expertise in precision mechanical design, fiber-optic sensing technology, materials, sealing, and structural design.

• Contribute to technical trade-off studies, design reviews, and multidisciplinary engineering discussions.

• Support root cause investigations and implement corrective engineering solutions.

• Improve subsystem robustness, manufacturability, maintainability, reliability, and production readiness.

• Plan and execute assigned engineering activities within agreed priorities and timelines.

• Communicate technical progress, risks, and dependencies proactively with stakeholders.

• Collaborate effectively across multidisciplinary teams and share engineering knowledge and best practices.

• Ensure engineering deliverables meet quality, performance, and reliability requirements.

• Contribute to the continuous improvement of engineering processes, methods, and product quality.
