Job summary

Persona AI in Houston, TX is seeking a Mechatronics Manufacturing Engineer to design, build, and validate test fixtures and end‑of‑line stations for humanoid robots in heavy industry. This hands‑on role spans mechanical, electrical, and software work to bring fixtures from concept to production.

You'll develop test stations, write automation scripts (Python, C/C++, LabVIEW), wire sensors, and collaborate with manufacturing, quality, and design engineering to ensure repeatable, safe, and fast

Qualifications

• Bachelor’s degree in Mechanical Engineering, Electrical Engineering, Mechatronics, or a related field, or equivalent hands‑on experience.
• 3+ years of experience in a production environment building test fixtures, assembly tooling, or manufacturing test equipment, ideally in electronics, robotics, automotive, or similar hardware production environments.
• Comfortable working across mechanical and electrical disciplines: you can design a simple mechanical fixture, wire up sensors and actuators, and write the code to make it all work together.
• Practical CAD skills (SolidWorks, Onshape, Fusion, or similar) for fixture and tooling design.
• Basic electrical skills: reading schematics, wiring test stations, using DAQ/PLC hardware or simple embedded controllers (Arduino, Raspberry Pi, microcontrollers).
• Programming ability in at least one language commonly used for test/automation (Python, C/C++, LabVIEW, or similar).
• Strong troubleshooting instincts — comfortable diagnosing whether a problem is mechanical, electrical, or software before reaching for a fix.
• A hands‑on, get‑it‑working mindset with attention to repeatability, safety, and ease of use for the technicians who’ll run your fixtures every day.
• A friendly, collaborative attitude and strong communication skills; design without ego.

Responsibilities

• Design and build test fixtures, jigs, and assembly aids that support fabrication, assembly, and end‑of‑line test of robot subsystems (actuators, manipulators, harnesses, and integrated assemblies).
• Develop end‑of‑line and in‑process test stations, including mechanical hardware, sensor and instrumentation integration, and the control/test software that runs them.
• Select and integrate sensors, actuators, motors, and simple control electronics into fixtures and test equipment.
• Write test scripts and simple applications (e.g., Python, C/C++, LabVIEW) to automate data collection, pass/fail criteria, and test sequencing.
• Work with manufacturing, quality, and design engineering to define what “good” looks like for a given part or assembly, and translate that into a testable, repeatable procedure.
• Iterate quickly on fixture and station designs based on line feedback, failure data, and changing product designs.
• Debug fixtures and test stations on the floor — mechanical, electrical, and software issues alike — to keep the line running.
• Document fixture designs, test procedures, calibration steps, and maintenance instructions for use by manufacturing and test technicians.
• Support DFM/DFT feedback to design engineering based on what you learn building and running test and assembly equipment.
• Perform statistical analysis of quality metrics and provide feedback to manufacturing processes and system designs.
