Duties & Responsibilities: Senior Test Engineer VIAVI Solutions — Fiber Instruments NPI | Indianapolis, IN Summary Join the founding members of a new Operations Engineering NPI team in Indianapolis, chartered with bringing VIAVI's next generation of fiber optic test instruments — OTDR modules, handheld fiber testers, optical power meters and sources, and automated fiber certification systems — from R&D into volume manufacturing.

This is a hands-on NPI and manufacturing test engineering role focused on optical instrument automation, rack-and-stack system design, and code development, working in close partnership with R&D in Indianapolis and VIAVI's prime fiber optic design center in St. Etienne, France. Note to Applicants: This is a factory automation and manufacturing test engineering role. It is NOT a field service, customer-facing applications engineering, or product management position.

Professional Growth and Tooling We're building this team from the ground up and investing in the right engineer to help shape it: Averna Launch Certification: We provide full training on our standard test executive wrapper. Unlimited NI Training: Access to National Instruments modules to elevate your TestStand skills to Architect level. Advanced Photonics Lab Access: Direct access to tunable laser sources, high-precision OTDR reference modules, and optical spectrum analysis instrumentation.

Essential Duties and Responsibilities Architect Production Test Systems: Design, build, and deploy automated test racks for New Product Introduction (NPI) and legacy fiber instrument manufacturing (OTDR modules, handheld testers, optical power meters and sources). Instrument Control: Write robust drivers and test sequences in Python, C++, or NI TestStand to control optical power meters, tunable laser sources, optical switches, variable optical attenuators (VOAs), and reference-grade OTDR modules.

Complex Optical Analysis: Develop algorithms to measure optical parameters (insertion loss, return loss, dynamic range, dead zone, pulse width, wavelength accuracy, linearity) for fiber optic test instruments. Statistical Quality Control: Implement Gauge R&R, Cpk, and Measurement Uncertainty analysis. Design for Test (DfT): Partner with R&D in Indianapolis and the prime fiber optic design center in St.

Etienne, France to ensure new products are designed for automated test access. Project Planning: Drive detailed planning to ensure all test solutions are developed, documented, debugged, deployed, and validated prior to production pilot run. Fixture Development: Partner with R&D and the Senior Manufacturing Engineer to develop contract manufacturing-ready test systems, fixtures, and optical launch/connectorization jigs.

Process Optimization: Optimize calibration and test processes for coverage, cycle time, and test stand capacity. System Deployment: Install and validate production systems at the Indianapolis facility and contract manufacturing sites. Lifecycle Maintenance: Maintain and update existing production test processes throughout the product lifecycle. Documentation: Produce written documentation including test specifications, procedures, installation instructions, interconnect diagrams, and prev
