Senior Electrical Engineer

Key Responsibilities:

• Serve as the senior electrical engineering owner for released LightWELD products, accessories, subsystems, and supporting production test equipment.
• Provide sustaining engineering support throughout the LightWELD product lifecycle, including production, service, field support, and product improvement.
• Lead the investigation and resolution of complex electrical, electronic, and electromechanical issues identified in manufacturing, testing, service, or customer use.
• Perform detailed root-cause analysis of field returns, production failures, intermittent faults, component failures, and system-level performance issues.
• Develop and implement corrective and preventive actions using structured problem-solving methods.
• Design, analyze, modify, and validate analog, digital, power, control, communication, and embedded electronic circuits used within LightWELD products.
• Support LightWELD electrical subsystems, including power conversion, controls, sensors, safety interlocks, cooling-system electronics, communications, user-interface hardware, and related electromechanical interfaces.
• Evaluate and approve component substitutions resulting from obsolescence, supply constraints, quality concerns, cost-reduction initiatives, or supplier changes.
• Lead electrical component qualification and alternate-part validation activities.
• Manage electrical product changes through formal engineering change-control processes.
• Create and maintain engineering documentation, including requirements, schematics, wiring diagrams, bills of material, specifications, risk assessments, test plans, test procedures, and validation reports.
• Lead LightWELD reliability, manufacturability, serviceability, quality, and cost-improvement initiatives without compromising product performance or safety.
• Develop and improve test methods, diagnostic procedures, fixtures, and tools for engineering, manufacturing, quality, and field-service teams.
• Analyze manufacturing, service, warranty, and field-return data to identify failure trends and prioritize product improvements.
• Provide hands-on manufacturing support, including troubleshooting, nonconformance resolution, deviation reviews, rework instructions, and production process improvements.
• Collaborate with suppliers and contract manufacturers to resolve component, assembly, workmanship, and quality issues.
• Conduct electrical design reviews and provide technical guidance to engineers, technicians, and cross-functional project teams.
• Ensure released documentation remains accurate and consistent with the current LightWELD product configuration.
• Support product safety, electromagnetic compatibility, environmental, and applicable regulatory compliance activities.
• Participate in design failure mode and effects analyses, product risk assessments, fault-tree analyses, and safety reviews.
• Provide technical support for customer escalations and assist service teams in diagnosing complex LightWELD system issues.
• Mentor less-experienced engineers and technicians and promote disciplined engineering, documentation, and problem-solving practices.

Required Qualifications:

• Bachelor’s degree in Electrical Engineering or a closely related engineering discipline.
• 10 or more years of professional electrical engineering experience, including substantial experience in sustaining engineering or released-product support.
• Demonstrated experience supporting complex industrial, commercial, or capital-equipment electronic products in a production environment.
• Strong knowledge of analog and digital circuit design, power electronics, control systems, sensors, signal conditioning, communications, and electrical interfaces.
• Proven ability to troubleshoot complex electrical and electromechanical systems using oscilloscopes, multimeters, power analyzers, logic analyzers, electronic loads, and related laboratory equipment.
• Experience reading, creating, and reviewing electrical schematics, wiring diagrams, bills of material, PCB documentation, specifications, and test procedures.
• Demonstrated experience leading root-cause investigations and implementing effective corrective and preventive actions.
• Experience with component qualification, alternate-part selection, design changes, and component obsolescence management.
• Working knowledge of design verification, validation, reliability testing, and production test methods.
• Experience working within formal engineering change-control and product lifecycle management processes.
• Strong written and verbal communication skills, with the ability to explain technical issues clearly to engineering, manufacturing, quality, service, suppliers, and management.
• Ability to manage multiple technical priorities and make sound, timely decisions in a fast-paced production environment.

Preferred Qualifications:

• Master’s degree in Electrical Engineering or a related discipline.
• Experience with handheld laser welding systems, industrial laser products, welding equipment, machine tools, or other high-power industrial electronic products.
• Experience supporting portable or handheld industrial tools.
• Familiarity with laser-system safety controls, redundant interlocks, emergency-stop circuits, and safety-critical design practices.
• Experience with embedded systems, microcontrollers, firmware interfaces, industrial communications, and system-level software diagnostics.
• Experience with high-voltage or high-current systems, switch-mode power supplies, DC bus architectures, motor drives, thermal controls, and cooling systems.
• Working knowledge of electromagnetic compatibility design, testing, and troubleshooting.
• Experience with PCB design and analysis tools, circuit simulation tools, product lifecycle management systems, and enterprise resource planning systems.
• Familiarity with Design for Manufacturing, Design for Test, Design for Service, FMEA, 8D, fault-tree analysis, and statistical problem-solving techniques.
• Experience working with domestic and international suppliers or contract manufacturers.

Leadership and Professional Competencies:

• Strong technical judgment and ownership of LightWELD product issues.
• A hands-on, data-driven approach to troubleshooting and decision-making.
• The ability to distinguish symptoms from underlying root causes.
• Effective leadership of cross-functional technical investigations.
• Attention to detail in safety-critical designs and technical documentation.
• The ability to balance technical rigor with product quality, cost, schedule, and business needs.
• The ability to work independently while communicating status, risk, and recommendations clearly.
• A strong commitment to product quality, customer satisfaction, and continuous improvement.

Work Environment:

• This position requires regular work in engineering laboratories, manufacturing areas, and product test environments. The role includes hands-on interaction with LightWELD products, production hardware, test equipment, and returned units.
• Occasional travel may be required to suppliers, manufacturing partners, customer locations, or field-service sites.
