## About the Role

* Bachelor's degree in Electrical Engineering, Mechanical Engineering, Mechatronics, or a closely related engineering discipline, or equivalent hands-on experience.
 * Demonstrated experience developing and integrating test systems for complex electromechanical products.
 * Strong experience working with systems that combine sensors, electric motors, motor control electronics, wiring, structural components, and embedded control systems.
 * Ability to write test software, develop test profiles, interface test controls with embedded hardware, and read or modify device-under-test software as needed.
 * Experience working with telemetry and real-time signals for automated testing, diagnostics, closed-loop control, or issue detection.
 * Hands-on experience with equipment such as data acquisition systems, power supplies, microcontrollers, wiring and relays, actuators, sensors, and custom test fixtures., * Experience testing robotic hands, grippers, actuators, precision mechanisms, or other high-degree-of-freedom electromechanical systems.

## Description

The Hands team is responsible for developing the robotic hands that allow NEO to interact with the physical world. The work spans complex electromechanical assemblies, actuators, sensors, motor controls, structures, and embedded systems.

As a Test Engineer, you will build the test infrastructure that allows the team to understand how these systems behave and prove that they are robust, capable, and ready for real-world use.

This is a highly hands-on role. You will spend time designing and building fixtures and test equipment, integrating instrumentation, writing test software, running tests, troubleshooting failures, and working directly with the hardware., * Robust test systems: Design and build end-to-end test systems for robotic hands and hand components, including fixtures, instrumentation, electrical interfaces, controls, software, and safety mechanisms.

 * Repeatable validation: Translate engineering requirements into reliable test methods that exercise sensors, motors, motor control electronics, structural components, and complete hand assemblies under representative loads and operating conditions.
 * Automated testing: Develop test software and control logic to configure test profiles, communicate with devices under test, collect telemetry, automate test progression, and detect issues in real time.
 * Hands-on test execution: Own tests from equipment bring-up through completion, including device integration, setup, monitoring, troubleshooting, inspections, and safe operation of test equipment.
 * Useful engineering data: Analyze telemetry and instrumentation data to identify anomalies, failure signatures, and trends. Turn raw test data into concise reports that clearly communicate results, risks, and recommended next steps.
 * Fast failure learning: Investigate failures quickly, reproduce unexpected behavior, and determine whether an issue originates in the test system or the product.
 * Scalable test infrastructure: Build reusable test software, instrumentation, and test architectures that improve validation coverage and increase engineering throughput as the hand program scales.

Key Competencies:

 * Test system development for complex electromechanical hardware
 * Electrical test and instrumentation
 * Test automation and software development
 * Data acquisition and telemetry
 * Closed-loop test control
 * Hardware/software integration
 * Failure investigation and root-cause analysis
