• Lead mechanical design, validation, and deployment for PCBA mechanical assembly, box build, and system-level mechanical assemblies.

• Serve as the mechanical SME for tooling, jigs, fixtures, and assembly process design across NPI and sustaining programs.

• Lead and participate in DFM/DFA, risk assessments, and design reviews with customers.

• Review and approve mechanical concepts to ensure DFM/DFA, quality, safety, ergonomics, and cost targets are met.

• Act as a primary technical interface to customers for mechanical assembly, tooling concepts, and manufacturing feasibility.

• Translate customer requirements into scalable, cost-effective, and automation-ready mechanical solutions.

• Drive mechanical readiness from prototype, pilot, ramp, to mass production in line with Flex NPI governance.

• Ensure tooling, jigs, and fixtures are properly designed, qualified, and released prior to production.

• Partner with Manufacturing Engineering, Tooling, Automation, Quality, and Program teams to ensure on-time program execution.

• Provide deep technical support for sheet metal assemblies, enclosures, and plastic mechanical assemblies, including fastening, alignment, tolerances, and structural integrity.

• Support cost optimization through design simplification, component standardization, and local sourcing strategies.

• Design and optimize production tooling, jigs, and fixtures to improve assembly efficiency, quality, and repeatability.

• Collaborate with internal teams and suppliers on tool fabrication, qualification, and deployment.

• Act as the technical interface with customers for mechanical design solutions.

• Provide recommendations on optimal design approaches, materials, and manufacturing methods.

• Support accurate BOM structuring, revision control, and engineering change management (ECN/ECO) within ERP.

• Integrate mechanical design outputs with shop floor execution systems (MES / shop floor control systems).

• Support digitalization of manufacturing processes, including data capture, reporting, and analytics.

• Identify opportunities to integrate basic automation in assembly processes.

• Utilize AI tools (design optimization, simulation assistance, documentation automation) to improve engineering productivity.

• Support implementation of smart manufacturing concepts.

The experience we're looking to add to our team:

• Strong analytical, problem solving, and decision-making skills.

• Sound engineering knowledge and experience to enable effective understanding of customer requirements and the operating environment.

• Strong knowledge and hands-on experience in sheet metal and plastic mechanical assemblies, including enclosures, tolerancing, fastening methods, and manufacturability considerations.

• Cost-conscious with the ability to critically analyse new and existing designs to drive cost reduction.

• Meticulous approach to quality with familiarity in FMEA and risk assessment.

• Proven experience with design tools/software, including 3D design packages (preferably Mechanical Desktop, Creo, or SolidWorks).

• Excellent communication skills with the ability to engage effectively with technical and non-technical stakeholders, including production personnel and executives, both internal and external.

• Exposure to automation systems and basic AI-assisted engineering tools.

• Experience with Industry 4.0 / smart manufacturing concepts is a strong advantage.

• Experience in high-mix, high-volume EMS or electronics manufacturing environments.

• Strong technical leadership with ownership, accountability, and bias for action.

• Ability to influence cross-functional and global teams.

• Customer-focused, data-driven, and results-oriented mindset.
