The position provides high‑level technical guidance to engineering, production, and assembly teams and is a key contributor throughout the product lifecycle, from concept through sustained production. Responsibilities Lead Mechanical Design Create detailed 3D CAD models and 2D drawings in SolidWorks for hydrophone and transducer subassemblies and mechanical housings. Design fixtures, jigs, molds, and assembly tooling. Perform trade‑analysis balancing performance, cost, and manufacturability. Apply GD&T and tolerance stack‑up principles to ensure repeatable, reliable assembly. Lead Design for Manufacturing (DFM) reviews and collaborate with engineering and production stakeholders. Maintain drawing standards, revision control, and technical documentation. Support product development from concept, through prototyping, to production handoff. Prototype Fabrication, Machining & Toolmaking Program, operate, and maintain manual and CNC machining equipment. Fabricate precision components, fixtures, housings, and tooling. Interpret engineering drawings and CAD models for accurate fabrication. Recommend design modifications to improve manufacturability or performance. Build and maintain mechanical fixtures for hydrophone and transducer testing. Additive Manufacturing & Advanced Processes Lead adoption and operation of additive manufacturing systems (polymer and/or metal). Identify opportunities where AM can reduce lead time or cost. Develop hybrid workflows combining machining and AM. Establish internal standards for AM‑produced components. Technical Problem Solving Support integration of mechanical and electronic components. Assist assembly staff in resolving mechanical challenges. Provide input on material selection, mechanical testing, and root‑cause investigations. Support ISO‑compliant documentation and process improvements. Machine Shop Development & Continuous Improvement Set up and maintain the machine shop environment. Implement 5S, safety practices, and preventive maintenance schedules. Organize tooling, work holding, and machining workflows for rapid turnaround. Evaluate and recommend new equipment or tools based on ROI and capability needs. Develop internal machining and AM standards to ensure consistency and quality. Qualifications Diploma or Degree in Mechanical Engineering Technology, Mechanical Engineering, Manufacturing Engineering, or related field. 8–15 years mechanical design and machining experience. Extensive SolidWorks experience (complex assemblies, drawings, configurations). Hands‑on experience with manual and CNC machining. Significant experience in fixture and manufacturing tooling design. Additive manufacturing experience preferred. Background in marine, acoustics, defence, or electronics packaging is an asset. Expert proficiency in SolidWorks modelling, drafting, and GD&T application. Strong understanding of machining practices, tolerances, and materials science. Ability to design and fabricate complex mechanical components. What’s In It For You... Comprehensive paid time off including vacation and personal days.
