Position Overview: The Manufacturing Process Engineer develops, documents, implements, and continuously improves manufacturing processes for One Stop Systems' high-performance computing products. This hands-on individual contributor partners with Engineering, Production, Quality, Planning, Purchasing, Test, and external manufacturing partners to transition new and derivative designs into repeatable production; improve safety, quality, delivery, cost, and labor performance; and maintain accurate routings, work instructions, tooling, process controls, and production data. The role applies Lean and data-driven problem-solving in OSS's high-mix, low-volume electronics and electromechanical manufacturing environment.

Reporting Relationships:

The Senior Manufacturing Process Engineer reports to the VP of Operations.

Duties and 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.

Qualifications:
• 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.

Competencies:
• Clear Communication Communicates technical information, risks, instructions, and decisions clearly and at the appropriate level of detail
• Cross-Functional Collaboration Builds productive working relationships across Engineering, Operations, Quality, Planning, Purchasing, Test, and external partners to achieve shared solutions.
• Continuous Improvement Actively identifies waste, variation, constraints, and process gaps and converts them into practical, sustainable improvements.
• Technical Problem Solving Uses structured analysis, evidence, and sound engineering judgment to identify root causes and implement effective countermeasures.
• Ownership and Follow-Through Takes responsibility for assigned processes and actions, maintains accurate documentation, and drives work to verified completion.
• Quality and Customer Focus Understands that process discipline, repeatability, traceability, and conformance directly affect product reliability and customer commitments.
