Responsibilities Will Include:
• Perform precision soldering and desoldering of power electronics components, including through-hole, high-current bus bars, and fine-pitch SMD devices (down to 0201 and BGA)
• Rework and modify PCBs and power modules based on engineering change orders and failure analysis results
• Safely handle high-voltage and high-current assemblies following electrical safety and ESD protocols
• Apply lockout/tagout (LOTO), proper PPE, and safe working clearances when working with energized or high-energy assemblies
• Conduct visual and functional inspection of PCBAs to ensure adherence to IPC-A-610 and IPC-7711/7721 standards
• Assist engineers with prototype power electronics builds, thermal evaluation hardware modifications, and field-return rework
• Support integration of large passive components (capacitors, inductors, bus capacitors) and power semiconductors (IGBTs, MOSFETs, SiC/GaN devices)
• Maintain detailed records of all rework and modifications for traceability
• Contribute to continuous improvement of soldering, rework, and safety processes focused on high-voltage applications

Desired Qualifications:
• Associate’s degree in Electronics Technology or equivalent experience preferred
• 2+ years of electronics assembly and soldering experience, ideally in power electronics, automotive, renewable energy, or related industries
• Demonstrated experience working safely with high-voltage systems and compliance with electrical safety protocols
• Familiarity with high-voltage PCB layouts, creepage/clearance rules, and conformal coating rework a plus
• Proficiency in fine-pitch SMD soldering and heavy copper through-hole component rework
• Ability to read schematics and assembly drawings
• Hands-on experience with soldering irons, hot air rework stations, preheaters, and microscopes
• A get-it-done attitude; no job is too big or too small

Physical Requirements:
• Ability to perform the essential job functions consistent safely and successfully with the ADA, FMLA and other federal, state and local standards, including meeting qualitative and/or quantitative productivity standards
• Ability to maintain regular, punctual attendance consistent with the ADA, FMLA and other federal, state, and local standards
• Ability to work with small components under a microscope for extended periods
• Manual dexterity for precision soldering and handling heavy copper assemblies
• Occasional lifting of up to 25 lbs

Working Conditions:
• Flexible working in different environments, such as office or outdoors
• Ability to work in challenging working conditions which may include exposure to noise, dust, chemicals, and temperature extremes, while protected by PPE, for extended periods of time
• Essential physical requirements, such as climbing, standing, stooping, or typing
• Occasional work weekends, nights, or be on-call as a regular part of the job
• Occasional travel requirements
