This role partners closely with engineering, manufacturing, quality, and operations to mature robust processes, develop capable teams, and deliver safe, compliant, high-quality hardware on schedule.

Responsibilities

• Lead daily special-process activities, assigning work and coordinating priorities across the process team
• Train, mentor, and provide technical direction to technicians and operators while promoting a culture of ownership, safety, quality, and procedural compliance
• Interpret and execute engineering drawings, CAD models, specifications, process standards, work instructions, travelers, and controlled procedures
• Develop, document, and oversee special processes, including bonding, sealing, welding, brazing, coating, surface preparation, heat treatment, or other process-specific operations as required
• Coordinate with design and manufacturing engineering to resolve process issues, provide producibility feedback, and implement design or process improvements
• Plan labor, materials, equipment, tooling, facilities, and work-cell readiness to maintain an efficient and predictable process flow
• Establish and verify process parameters, acceptance criteria, inspection methods, and required records in partnership with quality and engineering
• Lead process qualification, validation, first-article, and capability activities; document results and ensure compliance with applicable specifications and procedures
• Investigate nonconformances, defects, and process deviations; perform or support root-cause analysis and implement effective corrective and preventive actions
• Maintain clean, organized, and appropriately controlled work areas, including cleanroom or contamination-controlled environments when required
• Drive continuous improvement in safety, quality, throughput, repeatability, standard work, tooling, and special-process capability

Basic Qualifications

• 3+ years of hands-on experience in special processes, production and/or R&D process development, or a related field
• 1+ years of experience leading, mentoring, or coordinating the work of a special-process, manufacturing, or production team
• Ability to read and interpret engineering drawings, specifications, GD&T, CAD models, bills of material, work instructions, and technical documentation
• Working knowledge of process control, qualification, validation, inspection, traceability, and quality-system requirements for special processes
• Experience with one or more aerospace or high-reliability special processes, such as bonding, sealing, welding, brazing, coating, heat treatment, surface preparation, or non-destructive testing
• Ability to work effectively with engineering, quality, supply chain, and operations teams in a fast-paced research and development and production environment

Preferred Skills and Experience

• Experience developing or executing special processes for flight hardware or other safety-critical, high-reliability systems
• Experience with cleanroom or controlled-environment processing, ESD controls, FOD prevention, contamination control, or hazardous-material handling
• Experience creating or improving process specifications, work instructions, travelers, process-control plans, inspection plans, and qualification documentation
• Experience with process capability studies, statistical process control, measurement systems, and data-driven process improvement
• Experience with digital manufacturing, quality, inventory, or work-management systems and the…
