About the Job

We are seeking an experienced Test Systems Software Engineer to design and implement software for large-scale Hardware-in-the-Loop (HITL) test systems. This role requires architect-level expertise in LabVIEW and experience building sophisticated test automation systems that control complex hardware and manage large datasets.

As a Test Systems Software Engineer, you will architect the software backbone of our test infrastructure, creating systems that integrate hardware control, data acquisition, and real-time analysis. You will work closely with our electrical, mechanical, and controls engineers to build comprehensive test environments that push the boundaries of power generation technology. This is a hands-on role where you will both design scalable architectures and troubleshoot hardware interfaces alongside world-class engineers and technicians.

You will be responsible for the complete software lifecycle of test systems—from architecture design through deployment and long-term maintenance. This includes building CI/CD pipelines, designing database schemas, and creating visualization systems that enable breakthrough energy technology development.

Responsibilities

• Design and implement software controlling large-scale test rigs for hydraulic turbines, powertrains, and power electronics systems.
• Architect LabVIEW applications for electro-mechanical and hardware in the loop test systems.
• Integrate software systems with electrical and mechanical hardware across cross-disciplinary projects.
• Develop data acquisition and analysis systems with real-time processing capabilities.
• Design schemas and create visualizations using relational and time-series databases.
• Implement hardware communication protocols and interfaces.
• Build test sequences and automation scripts for hardware interaction.
• Troubleshoot laboratory hardware including oscilloscopes, DMMs, power supplies, electronic loads, and VFDs.
• Implement unit testing frameworks and automated validation systems.
• Establish git flow and version control processes for test software development.
• Create and maintain documentation for software architectures and test procedures.

Required Qualifications

• Bachelor’s degree in Physics, Computer Science, Electrical Engineering, or related field.
• 8–15+ years of experience in test software development and hardware automation.
• Certified LabVIEW Developer (CLD) or Certified LabVIEW Architect (CLA) level expertise.
• Demonstrated experience with LabVIEW OOP, Actor Framework, and DQMH.
• Experience communicating with laboratory instruments (oscilloscopes, DMMs, power meters, DAQ cards).
• Proficiency with hardware interface protocols (HTTP REST, MQTT, Modbus TCP, GPIB).
• Experience with relational and time-series databases and visualization tools.
• Python programming skills for hardware interface and test automation.
• Hands-on experience with industrial controls hardware including VFDs and PLCs.
• Experience with git flow, unit testing frameworks, and software validation methodologies.
• Strong troubleshooting skills for both software and hardware integration.
• Excellent communication skills for cross-functional collaboration.

Desired Qualifications

• Advanced degree in Physics, Computer Science, Electrical Engineering, or related field.
• Knowledge of real-time systems and deterministic software design.
• Experience with NI RT hardware platforms such as cRIO.
• Familiarity with VISA, Serial, HTTP REST, MQTT, GPIB, and Modbus communication.
• Experience with additional programming languages (Python, Rust).
• Experience with databases such as TimescaleDB, ClickHouse, InfluxDB, and Grafana visualization.
• Experience building CI/CD pipelines
