Job description

Midé operates as a research and development company specializing in sensors and smart material technologies. We support innovation for our parent organization, Hutchinson, a global supplier serving the automotive, aerospace, defense, and industrial sectors.Midé’sR&D efforts contribute to advancements in vehicle electrification and distributed industrial sensing, with a strong emphasis on Industrial Internet of Things (IIoT) applications.

Our project portfolio spans smart material applications, data acquisition tools, and signal processing software. We offer an environment that encourages learning, initiative, and creative thinking. Midé maintains a close-knit culture withroughly 60employees in our Woburn office, including a multidisciplinary engineering team across software, electrical, mechanical, and aerospace fields. We have successfully progressed multiple R&D initiatives into established product lines, including wireless data loggers and essential safety seals used on U.S. Navy vessels.

SUMMARY

The Firmware Engineer III will contribute to the design and development of embedded software for our low-power sensors, particularly enDAQ data acquisition devices. These sensors capture high-rate data such as acceleration, rotation, temperature, pressure, and humidity, sending raw or processed information to a local gateway that controls sensor operation, processes data, and connects to our Azure cloud platform. The role will focus primarily on firmware and related software, with optional opportunities for hardware involvement or project management responsibilities.

NOTE: Because Midé performs considerable work for the Department of Defense, this position may involve supporting defense-related programs.
