Summary The Senior Test Engineer will lead the development, enhancement, and long-term support of automated test systems used to validate integrated
optoelectronic laser engines. This role is primarily a
software engineering position focused on LabVIEW, with responsibility for building scalable test architectures, integrating complex instrumentation, and ensuring reliable, high-quality test coverage across development and production. The ideal candidate is a strong LabVIEW developer who enjoys solving system-level problems, designing clean software frameworks, and working with advanced test equipment.
Key Responsibilities - Architect, develop, and maintain LabVIEW-based automated test applications, including modular frameworks, reusable libraries, and scalable system architectures.
- Integrate and control a wide range of test instrumentation such as optical spectrum analyzers (OSAs), oscilloscopes, power meters, laser drivers, TEC controllers, and other electrical/optical test equipment.
- Develop automated test sequences, data acquisition routines, and instrument control interfaces for characterization, validation, and production workflows.
- Collaborate with cross-functional teams (firmware, mechanical, optical, manufacturing) to translate product requirements into robust test strategies and software implementations.
- Troubleshoot test system issues-primarily software, instrumentation control, and integration challenges.
- Implement structured data logging, automated analysis, and reporting pipelines to support engineering insights and manufacturing yield improvements.
- Maintain documentation, version control, and configuration management for test software and hardware.
- Provide technical leadership, code reviews, and mentorship to junior and mid-level test engineers.
- Drive continuous improvement in test reliability, maintainability, and throughput.
Required Qualifications - Bachelor's degree in Electrical Engineering, Computer Engineering, Physics, or related field.
- Extensive experience developing LabVIEW applications, including medium- to large-scale or multi-module systems.
- Strong hands-on experience interfacing with test instrumentation (OSAs, oscilloscopes, power meters, etc.).
- Solid understanding of automated test methodologies, software design patterns, and structured development practices.
- Ability to interpret system-level requirements and translate them into test software architectures.
- Strong analytical and troubleshooting skills, especially in complex test environments.
- Comfortable working with integrated systems that combine optics, electronics, and firmware, even if not performing deep electronics or optical debug.
Preferred / Nice-to-Have Skills - Experience with SQL or other database technologies for storing, querying, and analyzing test data.
- Familiarity with NI TestStand or similar test executive frameworks.
- Experience with Python, C#, or similar languages for auxiliary automation or tooling.
- Exposure to manufacturing test environments, reliability testing, or system-level characterization.
- Experience collaborating on automated test fixtures or working with mechanical engineering teams.
- Knowledge of data visualization or statistical analysis tools.
Soft Skills - Strong communication and documentation abilities.
- Ability to lead technical discussions and influence test architecture decisions.
- Detail-oriented with a focus on reliability, maintainability, and long-term system performance.
- Comfortable managing multiple priorities in a fast-paced engineering environment.
Compensation - Salary Range - $120,000 - $190,000 Depending on Experience
