Electrical Technician, ECU Testing

About the Role

Aptino, Inc. is seeking a hands-on Electrical Technician to support bench-level testing and validation of infotainment and telematics electronic control units (ECUs). This is a technician-level position focused on test execution and troubleshooting rather than engineering design or test development. An engineering degree is not required.

Key Responsibilities

• Set up and operate electronic test benches, laboratory equipment, and hardware validation setups.
• Configure test equipment and devices under test according to established procedures.
• Connect PCBAs and ECUs correctly to test setups, including using basic jumper wires and electrical connections.
• Execute test cases and procedures defined by engineers, observe system behavior, record measurements, and capture test results.
• Perform functional testing of infotainment and telematics ECUs, including audio, connectivity, user interface, and telematics features.
• Use laboratory instruments such as oscilloscopes, digital multimeters, and other diagnostic equipment to measure signals and investigate issues.
• Identify unexpected test results, perform initial troubleshooting, and report failures and defects to engineering teams.
• Support ECU flashing, configuration, and basic diagnostic activities as instructed.
• Maintain accurate test logs, measurement records, and validation reports.
• Assist with regression testing following hardware, firmware, or software updates.
• Work with hardware, software, quality assurance, and validation engineers to support issue investigation and resolution.
• Follow established test procedures, equipment handling guidelines, and quality requirements.

Requirements & Tech Stack

• High school diploma, technical diploma, associate degree, or equivalent practical experience in electronics or a related field.
• Hands-on experience with electronics testing, laboratory equipment, or hardware test benches.
• Ability to follow predefined test procedures, execute test cases, collect measurements, and document results accurately.
• Basic understanding of electrical circuits, electronic components, and PCBs/PCBAs.
• Experience setting up test equipment and connecting devices under test correctly.
• Familiarity with oscilloscopes, digital multimeters, and other basic electronic measurement instruments.
• Ability to read and interpret basic wiring diagrams, schematics, and connection instructions.
• Basic troubleshooting skills to identify connection problems, abnormal readings, and unexpected test results.
• Good communication skills, attention to detail, and the ability to work effectively with engineering teams.

Preferred Qualifications

• Familiarity with ECU testing, electronic modules, or automotive electronics.
• Experience testing automotive infotainment or telematics ECUs.
• Familiarity with automotive communication protocols such as CAN, LIN, and Ethernet.
• Basic knowledge of ECU flashing, diagnostics, and configuration tools.
• Experience with PCBA testing, board-level checks, and hardware validation.
• Exposure to CANoe, CANalyzer, or CAPL-based testing environments.
• Familiarity with Hardware-in-the-Loop (HIL) systems or automated test benches.
• Exposure to audio/video testing, connectivity features, Bluetooth, or infotainment user interface validation.
• Basic programming or scripting knowledge, such as Python, is an advantage.
• Familiarity with automotive quality procedures and testing standards.
