Software Manufacturing Test Engineer, Missiles

Responsibilities

• Own software manufacturing test activities in production, including station uptime, operator usability, and factory throughput.
• Develop PLC-integrated station control software using Modbus TCP for actuation, interlocks, and sensor acquisition.
• Build containerized station simulations, virtual CAN replays, and device simulators for hardware-free development and regression testing.
• Develop and maintain manufacturing test suites in Python and C# for hardware control, sequencing, instrument automation, operator interfaces, and services.
• Integrate test applications with sensors, DAQs, programmable power supplies, electronic loads, and vehicle compute hardware.
• Implement UART, CAN, RS-485, and RS-232 communications to command, flash, and validate devices under test.
• Deploy, configure, and debug test systems on Linux/Unix using terminal tools, SSH, and network debugging utilities.
• Use Nix and NixOS to create reproducible development and production test environments.
• Define test requirements, coverage, APIs, and pass/fail limits with hardware and firmware engineers during product development.
• Automate PCBA functional, full-system, and environmental stress screening tests.
• Perform root-cause analysis for electrical, firmware, and software manufacturing test issues.
• Integrate test stations with databases and Manufacturing Execution Systems while maintaining hardware traceability.
• Develop operator interfaces, error handling, and troubleshooting logs.
• Improve test sequences, cycle times, and coverage without compromising quality.
