Principal Test Engineer

Medtronic is seeking an experienced Principal Test Engineer to support manufacturing test engineering and test application development for the Acute Care Monitoring (ACM) business unit. The engineer will design, develop, implement, and validate manufacturing test methods, equipment, and applications supporting INVOS 4WL Neo/Ped sensors.

The ideal candidate will have strong experience in manufacturing test engineering, test application development, LabVIEW, TestStand, instrument integration, verification and validation, measurement system analysis, and manufacturing test methodology development. Experience with LED emitter characterization, optical sensors, spectroscopy, spectrometer integration, and photonics-based measurement systems is highly desirable.

This role will help translate R&D laboratory measurement methods into robust, production-ready, high-volume manufacturing test solutions.

Key Responsibilities

• Design, develop, implement, and maintain manufacturing test methods, test systems, and test equipment.
• Develop manufacturing test applications using LabVIEW and TestStand.
• Perform test instrument integration and develop automated test solutions for manufacturing environments.
• Support verification and validation (V&V) of test methods, applications, equipment, and manufacturing processes.
• Define manufacturing test requirements, methodologies, specifications, test limits, and validation strategies.
• Develop and document URS/SRS requirements for manufacturing test systems.
• Establish appropriate manufacturing test limits and guard bands based on product requirements and measurement capability.
• Perform Measurement System Analysis (MSA), Gauge R&R, repeatability, reproducibility, and uncertainty analysis.
• Analyze measurement variation, statistical performance, and manufacturing yield.
• Evaluate factors affecting optical measurement performance, including temperature, drive current, fixturing, alignment, and environmental conditions.
• Support LED emitter characterization and optical measurement system development.
• Work with optical sensors, spectroscopy, spectrometers, and photonics-based measurement systems.
• Develop and integrate spectroscopy and spectrometer-based test solutions where applicable.
• Translate laboratory measurement methods developed by R&D into robust, repeatable, production-ready manufacturing test systems.
• Compile and analyze test data and identify required changes to test equipment, test procedures, manufacturing processes, and test requirements.
• Plan and coordinate the labor, schedules, equipment, and resources required for testing and evaluating standard and special devices.
• Define testing parameters and specify tests required for manufacturing sample evaluation.
• Perform testing of customer samples and special tests that cannot be performed in the standard manufacturing test area.
• Troubleshoot moderately complex and undefined test and measurement problems through detailed data gathering, analysis, and investigation.
• Drive improvements to test systems, processes, and products to improve performance, reliability, and manufacturing capability.
• Collaborate with R&D, manufacturing, quality, product engineering, technical leads, vendors, and other stakeholders.
• Provide technical guidance, coaching, and training to engineers and lower-level professionals.
• Lead or support major and moderately complex projects from design through implementation.
• Communicate technical findings, project status, test results, and recommendations to internal and external stakeholders.
