Core Responsibilities

Primary Functions

Lead and mentor a team of mechanical engineers, providing direct technical guidance, constructive performance feedback, and strategic professional development support.
Spearhead the end-to-end mechanical design and development lifecycle for new products and systems, from initial concept and architecture through to detailed design, prototyping, and manufacturing transfer.
Own the technical roadmap and architectural decisions for major mechanical systems, ensuring alignment with product requirements, long-term strategy, and industry best practices.
Direct and perform complex 3D CAD modeling for components and assemblies using software like SolidWorks, Inventor, or Creo, ensuring designs are robust and well-documented.
Oversee and conduct advanced engineering analyses, including Finite Element Analysis (FEA) for stress and thermal, and Computational Fluid Dynamics (CFD) to validate design integrity and performance.
Establish and enforce rigorous design standards, best practices, and documentation protocols (e.g., drawings, BOMs, ECNs) to ensure consistency and quality across the team.
Drive the application of Design for Manufacturing (DFM), Design for Assembly (DFA), and Design for Cost (DFC) principles to optimize product quality, reliability, and profitability.
Serve as the primary technical point of contact for cross-functional teams, including electrical engineering, software, industrial design, and product management, to ensure seamless system integration.
Develop and manage comprehensive project plans, timelines, resource allocation, and budgets for all mechanical engineering deliverables, proactively identifying and mitigating risks.
Lead formal design reviews at key project milestones, confidently presenting technical concepts, analysis results, and design rationale to both technical and non-technical stakeholders.
Champion the selection and qualification of materials, components, and manufacturing processes, collaborating closely with supply chain and quality teams to vet and approve vendors.
Define and execute detailed verification and validation (V&V) test plans to ensure designs meet all functional, performance, reliability, and regulatory requirements.
Troubleshoot and resolve complex mechanical issues discovered during prototyping, testing, or field deployment, leading root cause analysis and implementing robust corrective actions.
Author and maintain comprehensive technical documentation, including design specifications, test reports, failure analysis summaries, and assembly procedures.
Stay at the forefront of emerging technologies, materials, and manufacturing methods, and champion their adoption to drive continuous improvement and innovation within the team.
Guide the development of test fixtures and equipment required for design validation, production testing, and quality control.
Make critical technical decisions on design trade-offs, balancing functionality, cost, and schedule constraints to achieve optimal project outcomes.
Ensure all designs adhere to relevant safety standards, environmental regulations, and industry-specific compliance requirements (e.g., UL, CE, FCC).

Secondary Functions

Collaborate with the quality assurance team to develop inspection criteria and test fixtures for incoming components and final assemblies.
Provide expert technical support to manufacturing and operations teams to resolve production-related challenges and improve process efficiency.
Participate in the strategic planning process, contributing expert insights to the development of the organization's long-term technology and product roadmap.
Assist in the recruitment, interviewing, and onboarding of new engineering talent to build and sustain a high-performing team.
Interface directly with external partners, key suppliers, and customers to communicate technical details, manage expectations, and gather critical feedback for design improvements.
Support intellectual property initiatives by providing detailed technical descriptions and drawings for patent applications related to novel inventions and design concepts.
