Core Responsibilities

Primary Functions

Spearhead the end-to-end mechanical design and development of complex products and systems, from initial concept and architecture through to mass production.
Provide technical leadership, mentorship, and guidance to a team of junior and senior mechanical engineers, fostering a culture of innovation, collaboration, and excellence.
Lead formal and informal design reviews, providing constructive feedback and ensuring that designs meet all technical specifications, quality standards, and customer requirements.
Serve as the principal technical point of contact for all mechanical engineering aspects of a project, effectively communicating status, risks, and dependencies to cross-functional teams and management.
Architect and oversee the creation of complex 3D CAD models and assemblies, ensuring best practices for modeling, data management, and configuration control are followed.
Direct and review the creation of comprehensive 2D manufacturing drawing packages, ensuring they are complete, accurate, and adhere to industry standards, including GD&T (ASME Y14.5).
Drive the application of advanced engineering analysis, including Finite Element Analysis (FEA) for structural integrity and Computational Fluid Dynamics (CFD) for thermal and fluid systems.
Develop and manage project timelines, resource allocation, and budgets for the mechanical engineering team, ensuring milestones are met and projects remain on track.
Champion and implement Design for Manufacturing (DFM), Design for Assembly (DFA), and Design for Service (DFS) principles early in the design cycle to optimize cost, quality, and reliability.
Lead root cause analysis investigations for complex mechanical failures encountered during testing or in the field, implementing robust and permanent corrective actions.
Define and execute comprehensive Design Verification & Validation (DV&V) test plans, including creating test fixtures, analyzing test data, and authoring detailed reports.
Manage the selection, characterization, and qualification of materials, components, and manufacturing processes to ensure performance and reliability requirements are met.
Collaborate closely with external partners, including component suppliers, contract manufacturers (CMs), and design consultants, to ensure seamless integration and execution.
Own the technical risk assessment process for mechanical systems, proactively identifying potential issues and developing mitigation strategies.
Develop and maintain system-level mechanical requirements and specifications, translating high-level product goals into actionable engineering targets.
Drive continuous improvement initiatives within the mechanical engineering team by refining design processes, tools, and methodologies.
Prepare and present detailed technical presentations and reports to a broad audience, including executive leadership, technical peers, and non-technical stakeholders.
Act as a key decision-maker on technical tradeoffs, balancing performance, cost, and schedule to achieve the optimal design solution.
Oversee the build and bring-up of prototype systems, providing hands-on support and troubleshooting to resolve integration issues quickly.
Ensure all designs and documentation comply with relevant industry standards, safety regulations (e.g., UL, CE), and environmental directives (e.g., RoHS, REACH).

Secondary Functions

Support ad-hoc data requests and exploratory data analysis related to product performance and reliability.
Contribute to the organization's technology strategy and product roadmap by evaluating new materials, processes, and design tools.
Collaborate with business units, product management, and industrial design to translate customer needs into tangible engineering requirements.
Participate in sprint planning, retrospectives, and other agile ceremonies to drive efficient project execution within the engineering team.
