## About the Role

* Strong software development in Python and C++ for test applications, instrument automation, and station infrastructure.
 * Systems thinking across electronics, firmware, software, robotics hardware, fixtures, and production processes.
 * Root-cause debugging grounded in data, logs, measurement, and controlled experimentation.
 * Hands-on hardware ability: reading schematics, probing boards, debugging signals, and using bench instrumentation.
 * Bias to action: makes decisions under production pressure, executes, and owns the result., * Background in Electrical Engineering, Computer Engineering, Computer Science, Robotics, or equivalent practical experience.
 * Proficiency in Python and/or C++, with willingness to work in both.
 * Ability to read schematics and debug electronics at the board or subsystem level.
 * Exposure to embedded systems, microcontrollers, or protocols such as CAN, SPI, I2C, UART, Ethernet, or EtherCAT.
 * Hands-on experience with bench instrumentation (oscilloscopes, logic analyzers, multimeters, programmable power supplies).

Preferred Skills:

 * Building production test stations, end-of-line testers, hardware-in-the-loop systems, or test infrastructure.
 * Robotics, electromechanical systems, motor controllers, sensors, actuators, batteries, embedded Linux, or real-time systems.
 * Deploying and maintaining software across multiple production PCs or factory stations.
 * Test-data pipelines, traceability, dashboards, WATS, MES, SQL, Splunk, or similar.
 * Linux, Docker, Git, CI/CD, Bazel, remote deployment, or automated station management.
 * AI-assisted development tools for faster software development, debugging, documentation, or fixture bring-up.

## Description

* Own functional and end-of-line test stations for robot subassemblies (feet, head, battery, hands, arms, power boards) across their full lifecycle - requirements through deployment, maintenance, and corrective action.
 * Ship operator-facing test apps with guided flows, clear pass/fail verdicts, robust error handling, and unit-level traceability.
 * Improve station uptime, cycle time, test coverage, data quality, and deployment repeatability as production scales.
 * Reduce escaped defects by reproducing and resolving failures across hardware, firmware, software, instruments, fixtures, and process - driving corrective action when stations or products fail.
 * Connect results, serial numbers, board IDs, and logs into test-data systems so production data becomes actionable insight.
