Working onsite alongside electrical, mechanical, thermal, and manufacturing engineers, you will translate complex schematics into reliable, manufacturable layouts and play a key role in maintaining our PCB design standards, Altium libraries, manufacturing documentation, and engineering release processes. ## Key Responsibilities PCB Design and Layout - Lead PCB layout and design for PCB stators, industrial motor controllers, VFDs, gate drivers, and power conversion systems, from component placement and stackup definition through routing and manufacturing output generation. - Collaborate closely with electrical engineers to translate schematic requirements into optimized PCB layouts. - Apply best practices for high-current routing, high-voltage isolation, grounding, signal integrity, high-speed design, EMI/EMC mitigation, and thermal management. - Design mixed-signal layouts that place sensitive analog and digital control circuits alongside high-power switching circuits. - Implement heavy-copper design practices, thermal vias, high-current interconnects, and appropriate power distribution techniques. Altium Design Rules and Verification - Configure, manage, and validate custom Altium Design Rule Check (DRC) requirements, including electrical clearances, routing constraints, differential pairs, and layer-specific rules. - Implement design constraints that enforce creepage, clearance, insulation, and high-voltage isolation requirements. - Lead and participate in design reviews, resolve DRC violations before manufacturing release, and recommend improvements to manufacturability, reliability, and cost. PCB Libraries and Design Standards - Develop and maintain Altium component libraries, including schematic symbols, PCB footprints, 3D models, and component data, with footprints and land patterns that meet IPC standards and manufacturer recommendations. - Design and maintain standardized schematic and PCB templates, fabrication and assembly drawings, and output job configurations. - Work with the engineering team to establish and continuously improve PCB design standards, workflows, library accuracy, and documentation consistency. Manufacturing Release and Supplier Support - Prepare complete fabrication and assembly documentation packages, including drawings, Gerber/ODB++ outputs, drill files, pick-and-place data, and BOMs. - Manage PCB and PCA design releases, revisions, and engineering change documentation through the company’s PLM system, ensuring design files and documentation are accurate, controlled, and traceable. - Verify designs against applicable IPC standards and DFM/DFA guidelines, including fabricator and assembler capabilities, prior to release. - Work with domestic and international PCB fabricators and contract manufacturers to investigate and resolve DFM, DFA, and production issues, and implement the resulting design improvements. - Support prototype builds, including component procurement and contract manufacturer coordination as needed, through design validation and the transition to volume manufacturing. Required Qualifications - Bachelor’s degree in Electrical Engineering, Electronics Engineering Technology, or a related technical discipline; Associate degree in Electronics Technology or a related field; or equivalent professional experience. - Minimum of 10 years of professional PCB layout and design experience, including complex multilayer designs developed independently from schematic through production release. - Advanced proficiency in Altium Designer (10 years), including PCB layout, component library management, design templates, custom DRC configuration, and manufacturing output generation. - Strong understanding of multilayer PCB stackups, controlled impedance, differential pair routing, return-path management, and signal integrity fundamentals. - Experience with high-current, high-voltage, and mixed-signal PCB design, including creepage, clearance, and EMI/EMC design principles. - Extensive knowledge of PCB fabrication and assembly processes, DFM/DFA, and applicable IPC standards, including IPC-2221, IPC-2152, IPC-7351/7352, IPC-A-600, and IPC-A-610. - Experience preparing manufacturing documentation and managing engineering revisions in a PLM or formal document control system. - Strong troubleshooting, technical communication, and cross-functional collaboration skills. ## Preferred Qualifications - PCB layout experience on industrial motor drives, VFDs, inverters, or power conversion equipment. - Experience designing heavy-copper (2 oz and above) and high-layer-count PCBs with complex stackups, high-current power distribution, and demanding thermal or fabrication requirements. - Experience with Arena PLM (Arena Solutions), including BOM control, engineering change orders (ECOs), and revision tracking for PCA releases. - IPC Certified Interconnect Designer (CID or CID+) certification. - Experience supporting high-volume PCB/PCA manufacturing with domestic and international suppliers, including resolving production yield issues. ## About Infinitum Infinitum develops high-efficiency electric motor systems that pair innovative PCB stator motors with integrated variable speed drives such as Aircore EC+, delivering efficient, compact solutions for industrial and commercial applications.
