With a global presence, we are proud to have offices in Canada, UK, Taiwan, Australia and Germany.
The Role
The Senior Mechanical Engineer is part of the engineering team that develops marine navigation and bridge systems for OSI’s government and naval markets that offer market leading performance and reliability, minimize production costs and are maintainable over an extended lifecycle. The Senior Mechanical Engineer leads and executed the mechanical design.

Key Responsibilities

• Leads detailed studies, experiments, research and tests in contributing to the design and development of navigation and bridge system products to established codes, standards, drawings, specifications and customer requirements, for both commercial and military customers
• Leads the mechanical design effort based on COTS, military grade products and customized solutions which includes the approval of parts and components
• Writes and maintains Company’s mechanical engineering standards and best practices
• Trains and mentors Mechanical Engineers on Company’s mechanical standards and best practices
• Approves elements of the Company’s parts database
• Interprets, analyzes, and approves hardware requirements, hardware design documents, and ensures the proposed solution meets the stated requirements
• Prepares and approves written plans, calculations, designs, specifications and material lists
• Leads and reviews technical tasks requiring accuracy of calculations, completeness of data and adherence to prescribed methods
• Provides design information and guidance to support personnel and, occasionally to suppliers, in preparation of detailed design, design testing and prototype fabrication.
• Ensures that designs meet system, customer and budgetary requirements and are compliant with industry and government standards
• Clearly communicates technical and design documentation to other departments
• Through the application of Engineering expertise and analysis, ensure mechanical designs are optimized for manufacturability, weight and cost. Work closely with Production to understand, develop, and refine assembly drawings and instructions.
• Ems Conducts and provides technical support during qualification testing. Perform engineering tests such as thermal cycling, vibration and shock testing, in the environmental test lab for both qualification and design verification testing. Design mechanical tests and test fixtures. Document and analyze results. Write formal test reports.
• Initiates and approves engineering change request (ECRs)
• Follows and promotes workplace operating and environmental, health and safety procedures and guidelines.
