Core Responsibilities

Primary Functions

Lead conceptual and detailed product design activities, producing CAD models, assemblies, and production-ready drawings that reflect GD&T, tolerancing, and manufacturing constraints to ensure reliable field performance.
Translate product requirements and specifications into detailed engineering deliverables, including BOMs, tolerance analysis, and cost targets, while balancing performance, manufacturability, and time-to-market.
Create and maintain 3D CAD models and 2D drawings using SolidWorks, Creo, or Inventor; ensure models follow company library standards, naming conventions, and are checked into PDM/PLM systems.
Develop and execute design-for-manufacturing (DFM) and design-for-assembly (DFA) strategies to reduce complexity, improve yield, and lower unit costs in collaboration with manufacturing and suppliers.
Perform tolerance stack-ups and tolerance analysis to validate fit/function across assemblies and subassemblies, and update designs to mitigate assembly or serviceability issues.
Conduct Failure Mode and Effects Analysis (DFMEA) and root-cause investigations, document mitigation actions, and track risk reduction through design iterations.
Create prototypes using in-house rapid prototyping and coordinate external prototyping vendors; plan and run prototype build cycles to validate form, fit, and function.
Plan and execute verification and validation test plans, including mechanical, electrical, thermal, and environmental testing; document results and update designs to meet reliability targets.
Perform finite element analysis (FEA) and simulation (structural, thermal, modal) using Ansys or equivalent tools to validate design assumptions and guide material/thickness choices.
Specify materials, finishes, and surface treatments, ensuring material selection aligns with mechanical requirements, cost constraints, and regulatory requirements (RoHS, REACH).
Generate and manage complete Bills of Materials (BOM), ECOs/ECNs, and engineering change documentation to support configuration control and traceability.
Collaborate with electrical engineers, firmware teams, and systems engineers for electromechanical integration, cable routing, and enclosure design to ensure EMC/EMI and thermal management.
Drive design reviews (preliminary, critical design review, production readiness), capture action items, and follow through to closure with cross-functional stakeholders.
Support supplier selection, technical RFQs, and supplier development to qualify components and production methods that meet quality, cost, lead time, and volume requirements.
Partner with Quality Engineering to define inspection criteria, test fixtures, and acceptance plans; support PPAP, IQ/OQ/PQ or similar production validation activities.
Optimize designs for sustainability and lifecycle considerations, including recyclability, material reduction, and energy efficiency where applicable.
Mentor junior engineers and CAD designers, provide constructive design reviews, and contribute to continuous process and tool improvements within the design team.
Track project schedules, present technical trade-offs, escalate risks, and propose mitigation plans to meet project milestones and launch targets.
Implement and maintain engineering standards, templates, and best practices for modeling, documentation, and review to improve team productivity.
Collaborate with procurement and program management to identify cost savings opportunities, component standardization, and part consolidation initiatives.
Ensure designs meet applicable regulatory and safety standards (UL, CE, FDA where applicable) by coordinating third-party testing and supporting regulatory submissions.
Maintain strong documentation practices: design rationales, test reports, assembly instructions, service manuals, and supplier quality requirements for full lifecycle support.

Secondary Functions

Support continuous product improvement initiatives by analyzing field returns, warranty data, and customer feedback to generate corrective design actions.
Assist in creating work instructions, assembly guides, and serviceability procedures to streamline ramp-up and reduce field service time.
Contribute to product roadmaps by evaluating emerging materials, manufacturing technologies, and vendor capabilities that could accelerate time-to-market.
Participate in cross-functional sprint planning and agile ceremonies for development cadences in organizations using agile product development.
Provide subject-matter expertise for cost-modeling, DFM workshops, and supplier audits to ensure design transfer readiness.
Support ad-hoc technical requests from sales, operations, and aftermarket teams, delivering design guidance and quick-turn CAD assets when needed.
