Original job description

At Luna Innovations, we measure and manage light in optical fiber. Our Optics/Polarization product line, based in Chino, CA, specializes in industry-leading components, modules, and test equipment for the characterization and control of optical polarization. Our instruments, ranging from dynamic optical delay/phase management and high-speed polarization state management to full-function polarization light analyzers, are critical for optical communications, silicon photonics testing, and fiber optic sensing. At Luna, you will work with some of the most curious, forward-thinking engineers and scientists in the industry to shape the future of fiber optic measurement. Role Overview We are seeking a Software Engineer II, with flexibility to hire at the Senior level for the right candidate, to join the software development team for our photonics instrumentation. Final level and pay will be based on experience, skills, and qualifications. You will build the applications that control precision optical instruments, process high-speed measurement data, and visualize complex optical behavior in real time. You will develop software for Linux and Windows platforms, including embedded Linux devices, and support the remote control interfaces customers use to integrate our instruments into their own test systems. If you are passionate about hardware-software integration and want to build the software behind state-of-the-art optical test equipment, we want you on our team.

Software Quality & Documentation: Apply code review, testing, debugging, validation, versioning, and technical documentation practices throughout development and release.
Cross-Functional Collaboration: Work with optical, electrical, firmware, and systems engineers, as well as manufacturing and support teams, to define instrument capabilities, troubleshoot prototypes, and bring new products to market.
