Job Description

Mechanical Assembler / Wire & Cable Assembler / Quality Tester - Sorrento Valley - $25/hr-$26/hr

Job Description

This role combines mechanical assembly, wire and cable harness assembly, and hands-on quality inspection and testing of electro-mechanical subassemblies and devices. You will build modules and PCBAs by following detailed computer-based work instructions, document each step in a manufacturing execution system, and perform firmware installation, functional testing, and troubleshooting to ensure every product meets stringent quality standards.

Responsibilities

• Assemble electro-mechanical subassemblies, modules, and PCBAs by following detailed work instructions in the manufacturing execution system (MES).
• Use the shop order system (42Q) daily to open work instructions, track tasks, and document each step of the manufacturing process, creating an accurate electronic device history record.
• Perform mechanical and electrical assembly work, including connecting wires and harnesses to modules and PCBAs by hand using appropriate tools.
• Work with hand and small power tools such as screwdrivers, wire strippers, crimpers, wrenches, torque wrenches, needle nose pliers, and other assembly tools in a safe and precise manner.
• Install firmware onto PCBAs by opening the required program on a laptop, running scripts to upload firmware, and verifying successful installation.
• Conduct functional testing of devices by selecting the appropriate test area, entering test codes via keyboard, running scripts, and monitoring test results to confirm proper operation.
• Attach cables to subassemblies, load test programs, and run scripts to perform comprehensive testing of assembled units.
• Document verification steps in the MES by selecting the area to be verified, entering system-generated numbers, and recording pass/fail results accurately.
• Troubleshoot failures identified by the testing software, investigate root causes, and perform necessary corrections and repairs to bring units into compliance.
• Follow all build plans and work instructions exactly, with no deviation from prescribed processes or procedures.
• Collaborate closely with technicians and team members during training and ongoing production to complete build plans and meet production goals.
• Participate in a daily 7:00 AM stand-up meeting to receive work assignments, review build plans, and align on team objectives.
• Communicate clearly with team members and leaders about issues, defects, and troubleshooting steps taken during the manufacturing and testing process.
• Maintain a strong focus on quality, accuracy, and consistency in all assembly, testing, and documentation activities.
• Adhere to ESD and safety requirements at all times, including proper use of lab coats, safety glasses, and other protective measures.
• Support continuous improvement by sharing observations from testing and troubleshooting activities and collaborating on process refinements.

Essential Skills

• Proven experience in mechanical assembly of electro-mechanical subassemblies, modules, or devices.
• Hands-on experience with wire harness assembly, wiring, crimping, and repair of electrical connections.
• Demonstrated background in testing and troubleshooting devices in previous roles, including a clear, structured troubleshooting process.
• Ability to use hand and small power tools proficiently, including screwdrivers, wire strippers, crimpers, wrenches, torque wrenches, needle nose pliers, and similar tools.
• Strong computer proficiency, including the ability to work on a computer throughout the day and navigate multiple software programs and windows.
• Experience entering data into a manufacturing execution system or shop order system (such as 42Q) and tracking work within that system.
• Ability to follow detailed, computer-based work instructions precisely, with no deviation from build plans.
• Comfort using email and collaboration tools such as Outlook and Microsoft Teams on a daily basis.
• background in electronics, including familiarity with testing concepts, basic electronic components, and the use of tools such as an oscilloscope.
• Strong communication skills, with the ability to clearly describe troubleshooting steps, defects found, and interactions with team leaders.
• Demonstrated ability to work effectively in a team-focused environment and contribute to shared build plans and goals.

Additional Skills & Qualifications

• Previous experience working in an electro-mechanical manufacturing or assembly environment with subassembly work.
• Experience with manufacturing execution systems, particularly 42Q, or
