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.
• Own the common test framework including custom and commercial products, data schema, sequencers, and hardware drivers
• 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.
