Senior Test Development Engineer

The role

This person will develop and own test systems for NEO's electronics and robotic subassemblies. The role involves building functional and end-of-line test stations from requirements through deployment and long-term support.

What you will do

• Own functional and end-of-line test stations for robot subassemblies across their full lifecycle.
• Ship operator-facing test apps with guided flows and unit-level traceability.
• Improve station uptime, cycle time, test coverage, data quality, and deployment repeatability.
• Reduce escaped defects by reproducing and resolving failures across hardware, firmware, software, instruments, fixtures, and process.
• Connect results, serial numbers, board IDs, and logs into test-data systems.

Required qualifications

• 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).

Nice to have

• 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.

Benefits

• Comprehensive medical, dental, and vision coverage
• Generous paid time off, company holidays, and parental leave
• 401(k) plan with company match (100% on the first 3% of contributions, 50% on the next 2%)
• Flexible Spending Accounts (FSA) and Health Savings Accounts (HSA) options
• Commuter benefits (transit and parking)
• Short-term and long-term disability, and life insurance
• Employee Assistance Program (EAP) for mental health, financial, and personal support
• Onsite snacks and catered lunches
