Responsibilities

Build products and provide services with the highest Flexibility, Productivity, and Quality

Achieve total customer satisfaction through technical excellence and responsive engineering support

Ensure successful NPI launches through cross-functional collaboration, process validation, and data-driven feedback to design and quality teams

Support production operations in the following categories:

Reduce downtime caused by engineering issues (programming, MPI errors, tooling, design, or line stoppage)

Improve quality yield through root cause analysis, corrective actions, and robust process setup

Lead NPI and prototype builds, ensuring process readiness, documentation completeness, and manufacturability validation prior to production release

Provide engineering services to meet customer needs and expectations in the following areas:

Design for Manufacturability (DFM)

Manufacturing Process Instruction (MPI) creation and maintenance

Engineering Change Order (ECO) implementation

Defect Reduction Team (DRT) meetings and follow-up actions

Failure analysis and corrective action documentation

Develop and validate new or modified processes, including process capability studies, DOE validation, and reflow/wave solder profile optimization

Other engineering requests as required by customers or management

Review daily SMT or build schedule to ensure process readiness

Confirm all required items are complete and available prior to production:

Job package with full build documentation

Manufacturing Process Instruction (MPI) reviewed and approved

Routing definitions for data collection

Validated reflow or wave solder profiles

ECOs, deviations, or special instructions incorporated into the MPI and/or job package

All required tooling available and verified

Review pre-build DFM, document known defects, and hyperlink details in the MPI

Lead cross-functional NPI kickoff meetings to review design requirements, risk areas, and special process considerations

Document and track NPI issues and lessons learned for future builds

Coordinate with Program Managers to resolve DFM showstoppers prior to build

Analyze previous quality data, identify recurring defects, determine root causes, and implement corrective actions

Design, order, and verify all required tooling (stencils, wave solder pallets, press-fit fixtures, conformal coat fixtures, etc.)

Maintain tooling logs, labeling, and readiness tracking within Omega Build Readiness

Inspect and sign off first article setups for critical processes (stencil printer, reflow oven, wave solder, etc.) using the First Article Checklist

Inspect initial boards after print and reflow for solder release, bridging, voids, and process anomalies. Document findings and sign off the First Article Report

Provide on-the-floor training for operators and technicians regarding new processes, corrective actions, or observed deficiencies

Support production by promptly responding to technical inquiries or line support issues

Exercise full authority to stop the line if repeated defects or safety concerns are observed

Review production data in Omega Data Collection, identifying root causes and corrective actions

Review Daily, Weekly, and Customer Quality Reports to identify trends, recurring issues, or process gaps

Provide structured analysis and report findings to Quality and Production (using 8D or equivalent methodology)

Document corrective actions and verify implementation during the next production run

Present findings and improvement updates in internal and customer quality meetings

Create and submit Post-Build DFM reports to Program Managers with improvement recommendations

Implement and validate ECO changes per revision control procedures

Perform and document detailed failure analyses for internal and customer returns

Participate in process improvement projects and defect-reduction initiatives

Provide customer-driven engineering services or special support requests

Develop and deliver internal technical training for operators and peers

Support ISO 9001 and AS9100 activities, including audits, documentation, and Work Instruction updates
