InvenSense technology can be found in Mobile, Wearables, IoT, Smart Home, Industrial, and Automotive products.

At InvenSense, we take pride and find satisfaction in doing our jobs well, and we value the companionship that comes from working with others who share our total commitment to our customers and one another. We are looking to hire a motivated and talented Engineer with experience in developing and automating test strategies for the optimization and validation of our mobile and embedded software to help us continue our impressive growth as a global market leader in MEMS SoC solutions, and to offer efficient and innovative algorithms to address the needs of our customers.

Mission

You will bring your technical expertise in the fields of software development, you will deliver innovative solutions to improve and automate our validation processes. Your attention to quality and detail will help you identify and propose enhancements to boost the performance of our algorithmic solutions (signal processing and artificial intelligence) for motion sensors, audio sensors, and ultrasonic distance measurement sensors.

Our projects will lead you to work across various domains, from Smartphones to the Internet of Things, including drones, robotics, wearables, earbuds and smart glasses.

Your software development skills, combined with your knowledge of signal processing and artificial intelligence, will be key assets in proposing and developing new validation strategies, helping us tackle upcoming challenges in the evolution of our sensor systems. You will collaborate within our team to support the development of validation tools and work closely with development engineers and algorithm specialists to design validation strategies and develop metrics for continuously assessing and improving the quality of our solutions.

This position based in Grenoble, France, as permanent full time (Contrat de travail à Durée Indéterminée, CDI).

You will be part of an international team spread across two sites: Grenoble - France and San Jose - California.
