## About the Role

Do you have experience in Voltage testers?, * Strong Software Engineering: 4+ years (or strong equivalent) writing production-quality code daily in Python, C/C++, or TypeScript, with deep test-automation and CI/CD experience (Playwright, pytest, or similar).

 * Controls & Industrial Automation: Hands-on background with PLC programming and industrial communication protocols (Modbus TCP/RTU, EtherNet/IP, EtherCAT, PROFINET) and digital/analog I/O.
 * Electrical Fundamentals: Reads electrical schematics, comfortable with signal types (24V digital I/O, 4-20mA analog) and test equipment (multimeters, etc.), and can build and wire test fixtures and PLC cabinets.
 * Systems Thinking: Comfortable debugging networked, distributed, and real-time systems across the software/hardware boundary.
 * Impact Driven: You value simplicity, reliability, and velocity, and would rather prevent a bug than file one., A developer with a controls or industrial-automation background who wants to apply strong software skills to robotics quality at the hardware seam - equally at home in a codebase and in front of a PLC cabinet., * Allen-Bradley, Siemens, or Beckhoff PLC platforms; structured text
 * ROS2, Docker, or robotics software stacks
 * Hardware-in-the-loop or system-level test automation at scale
 * Industrial safety standards (ISO 13849, ANSI/RIA 15.06)

## Description

* Build and own automated test suites and hardware-in-the-loop infrastructure for the controls and industrial-integration (PLC, HMI, fieldbus, I/O).
 * Exercise industrial communication protocols in code: Modbus TCP/RTU, EtherNet/IP, EtherCAT, PROFINET, along with digital/analog I/O behavior.
 * Build SW-based simulators and mocks for PLCs, fieldbus devices, conveyors, grippers, and safety hardware so controls testing isn't gated on physical equipment.
 * Fold safety-system integration (e-stops, safety PLCs, light curtains) into automated release validation against industrial safety standards.
 * Validate integrations in real time during the sprint, partnering tightly with software and applications engineers so defects are solved as they appear.
 * Hand off maintainable test code and fixtures to Systems Test Engineers and Technicians, and review designs and PRs for testability and protocol compliance.
