Bachelor's degree in Manufacturing, Industrial, Mechanical, Electrical, or a related engineering field; equivalent relevant education and experience may be considered.
Minimum 7 years of manufacturing or process engineering experience in a high-mix, low-volume electronics, electromechanical, aerospace, defense, or similarly regulated manufacturing environment.
Demonstrated hands-on experience with new product introduction, production-readiness activities, first builds, work-instruction development, manufacturing routings, time studies, labor standards, and tooling or fixture development.
Working knowledge of Lean manufacturing and structured problem-solving; Lean Six Sigma Green Belt or comparable certification preferred.
Strong root-cause analysis, data analysis, and corrective-action skills, with the ability to convert operational data into practical process improvements.
Ability to read and interpret engineering drawings, bills of material, engineering change notices, specifications, acceptance requirements, and other technical documentation.
Experience with ERP and MES systems; experience with Infor CloudSuite Industrial/SyteLine and Factory Track preferred.
Proficiency with Microsoft Office and data-visualization tools; experience with Power BI, Power Apps, Power Automate, or related tools preferred.
Experience supporting AS9100 or ISO 9001 quality systems; knowledge of ISO 14001 and controlled manufacturing documentation preferred.
Demonstrated ability to manage multiple priorities, work effectively on the manufacturing floor, and drive cross-functional actions to completion in a fast-paced environment.
Excellent written and verbal communication, organizational, project-management, and interpersonal skills.

Responsibilities

Develop, document, implement, and improve manufacturing processes across receiving, kitting, assembly, integration, production test, final inspection, and shipping.
Lead the manufacturing workstream for new product introduction and production readiness reviews, including design-for-manufacturability and design-for-assembly feedback, pilot and first-build support, manufacturing risk identification, and closure of readiness actions.
Create and maintain controlled manufacturing documentation, including visual work instructions, assembly procedures, routings, standard operations, manufacturing notes, labor standards, and process verification records.
Design, develop, validate, and improve production fixtures, jigs, templates, tooling, ergonomic workstation layouts, and material presentation methods to improve repeatability, safety, quality, and throughput.
Conduct time studies, cycle-time analysis, line balancing, and workflow analysis; establish and maintain realistic labor standards, routing times, resource assignments, and capacity assumptions in the ERP/MES environment.
Apply Lean and Six Sigma methods, including 5S, standardized work, value-stream mapping, Kaizen, waste elimination, root-cause analysis, and DMAIC, to improve flow, reduce variation, and sustain process gains.
Analyze in-process and final inspection yield, defects, rework, scrap, labor variance, RMA trends, and other operational data; lead or support cross-functional corrective actions and verify effectiveness.
Improve the quality and usability of manufacturing data in Infor CloudSuite Industrial/Factory Track or related ERP/MES systems.
Support demand and capacity planning by identifying process constraints, validating routing and resource data, modeling labor requirements, and recommending practical load-leveling, staffing, tooling, or outsourcing actions.
Evaluate manufacturing automation, capital equipment, and process-technology opportunities; prepare technical and cost justification, coordinate implementation, and validate performance before release to production.
Support contract manufacturers and special-process suppliers by defining manufacturing documentation, tooling, quality, traceability, and process requirements; participate in launch readiness and supplier process-improvement activities.
Train assemblers, technicians, inspectors, and other users on new or revised processes and verify that standardized work is understood, effective, and sustained.
Support AS9100, ISO 9001, and ISO 14001 requirements through controlled documentation, objective evidence, process discipline, equipment maintenance and calibration coordination, traceability, audit support, and corrective action.
Identify and address manufacturing safety, ergonomic, and environmental risks associated with processes, tooling, workstations, and equipment.
Provide concise project updates, risk assessments, recommendations, and implementation status to Operations leadership and cross-functional stakeholders.
Performs other duties as assigned.
