Freelance Power Electronics Engineer Jobs in Delaware

Symbotic is seeking a Senior Test Engineer (EE) to lead the development, deployment, and continuous improvement of manufacturing test solutions for complex electromechanical and robotic systems. The role drives electrical test architecture, develops scalable manufacturing test fixtures, supports PCBA and hardware design, and leads deployment activities across internal manufacturing sites and Contract Manufacturers (CMs).

• Lead the design and development of electrical schematics, PCBAs, and interface boards for manufacturing test fixtures and validation systems.
• Own end-to-end hardware bring‑up activities including component selection, schematic reviews, layout reviews, soldering/rework, and board-level debugging.
• Architect and develop scalable manufacturing test systems involving power distribution, relays, multiplexing, signal conditioning, DAQ systems, and measurement instrumentation.
• Develop and maintain automated test software and frameworks (Python preferred) for instrument control, test execution, data logging, and production diagnostics.
• Perform advanced electrical debugging using oscilloscopes, logic analyzers, DMMs, power analyzers, and protocol analyzers to isolate board-level and system-level failures.
• Lead manufacturing deployment and production support activities across internal sites and Contract Manufacturers (CMs), including troubleshooting, yield improvement, and failure analysis.
• Analyze test data, production failures, and field issues to drive improvements in product reliability, test coverage, and manufacturing efficiency.
• Define test strategies, validation plans, and manufacturing test requirements for new product introductions (NPI).
• Collaborate closely with Electrical, Firmware, Software, Mechanical, and Manufacturing Engineering teams to resolve technical challenges and improve system performance.
• Lead technical projects and coordinate execution timelines, deliverables, and deployment readiness.
• Mentor and provide technical guidance to junior engineers and technicians, fostering engineering best practices and debugging methodologies.
• Drive continuous improvement initiatives for test architecture, fixture reliability, automation, and operational efficiency.

• B.S. in Electrical Engineering (or equivalent) with a minimum of 8 years of hands‑on experience in electrical hardware design, manufacturing test engineering, or system validation.
• Strong expertise in schematic capture, PCBA design, and hardware development using tools such as Altium.
• Extensive experience in board bring‑up, soldering, rework, and component-level debugging.
• Deep understanding of analog and digital circuit design, including power electronics, signal integrity, grounding, EMI/noise considerations, and protection circuits.
• Hands‑on experience with electrical test instrumentation: oscilloscopes, DMMs, programmable power supplies, electronic loads, logic analyzers, and DAQ systems.
• Experience designing and building manufacturing test fixtures involving relays, multiplexers, interface boards, and automated measurement systems.
• Proficiency in Python or similar scripting languages for test automation and manufacturing diagnostics.
• Strong experience supporting manufacturing environments and working directly with Contract Manufacturers (CMs).
• Experience with communication protocols (CAN, UART, SPI, I2C, Ethernet) and related debugging tools.
• Familiarity with data logging, database integration, test result analytics, and failure trend analysis.
• Experience with embedded systems, sensors, motor systems, or electromechanical products.
• Proven ability to lead technical projects, drive execution, and mentor junior engineers.
• Strong communication, organizational, and cross‑functional collaboration skills.

• Experience working with robotics, automation systems, or high‑volume manufacturing environments.
• Familiarity with SCPI‑based instrument control and automated validation frameworks.
• Experience with production diagnostics, reliability testing, and root‑cause analysis methodologies.
• Knowledge of manufacturing processes, fixture ergonomics, and design‑for‑test (DFT) principles.
