Acting as the primary technical interface with customers, the Principal Mechanical Engineer will translate customer requirements into robust engineering solutions, lead technical discussions, coordinate multidisciplinary engineering activities, and mentor the mechanical engineering team while maintaining direct involvement in product development. The role is instrumental in delivering innovative systems from concept through industrialization while fostering engineering excellence and continuous improvement. Responsibilities End-to-End Product Development Own the complete mechanical development lifecycle of complex engineering systems, from customer requirements and concept generation through design, verification, validation, industrialization, production release, and lifecycle support. Lead the mechanical architecture and detailed design of high-performance mechanical systems and precision-engineered assemblies. Remain actively involved in hands‑on engineering activities, including CAD design, design reviews, prototyping, engineering calculations, testing,



and technical problem‑solving. Define engineering solutions that balance performance, reliability, manufacturability, weight, cost, and lifecycle requirements. Drive Design for Manufacturing (DFM), Design for Assembly (DFA), Design for Cost (DFC), and Design for Reliability (DFR) throughout product development. Support engineering change management, configuration control, root cause investigations, and continuous product improvement. Customer Technical Leadership Act as the primary technical interface with customers throughout the complete product development lifecycle. Capture customer needs and translate business and technical requirements into innovative engineering solutions. Lead technical workshops, design reviews, project meetings, and engineering presentations with customers. Provide technical leadership during proposal development, feasibility studies, and product definition activities. Build long‑term technical relationships with customers while ensuring successful project execution and high levels of customer satisfaction. Technical Leadership Provide day‑to‑day technical leadership and mentoring to the mechanical engineering team. Review and approve engineering designs, calculations, analyses, technical documentation, and validation activities. Promote engineering standards, design best practices, and continuous improvement initiatives across the mechanical engineering function. Foster a collaborative, accountable, and high-performance engineering culture through coaching and knowledge sharing. Support capability development and contribute to the growth of the engineering organization. Cross-functional Collaboration and Project Delivery Collaborate closely with Electronics, Systems Engineering, Software, Manufacturing, Quality, Supply Chain, and Project Management teams throughout the product lifecycle. Coordinate engineering activities with suppliers and manufacturing partners to ensure successful product industrialization.



Support project planning, technical estimation, resource forecasting, and technical risk management. Communicate technical progress, risks, and engineering recommendations to senior management and key stakeholders. Ensure engineering deliverables are completed within agreed technical, quality, budget, and schedule objectives. Required Qualifications Bachelor's or Master's degree in Mechanical Engineering or a closely related engineering discipline.
