Job description

ABOUT US

Midéis is a research and development company focused on sensors and smart materials. We help drive innovation for our parent company, Hutchinson, which is a global supplier to the automotive, aerospace, defense, and industrial markets. Midé’s R&D supports Hutchinson’s efforts toward vehicle electrification and distributed industrial sensing, especially in industrial internet of things (IIoT) solutions.

We have a diverse set of projects ranging from innovative uses of smart materials to data acquisition and signal analysis software. Our small company feel provides a great place to learn, as well as a place that rewards people who drive their own ideas. Midé has about 60 people working out of our Woburn office, including over 20 engineers divided between software, electrical, mechanical, and aerospace. Midé has successfully transitioned a number of its R&D programs to product lines ranging from wireless data loggers to critical safety seals used on U.S. Navy ships.

NOTE

Midé conducts a significant amount of work for the Department of Defense, and this position may require participation in defense work.

EDUCATION AND EXPERIENCE

• BSE (EE, ECE, CS, or similar) required

• Experience with STM32 microcontrollers
• Wi-Fi / lwIP networking in low‑power and embedded contexts like the ESP32 platform
• Some familiarity with IoT and Cloud (particularly Azure) systems, including MQTT, IoT Edge, and cloud fundamentals
• Embedded multitasking operating systems like FreeRTOS
• Implementing serial protocols such as I²C and SPI
• Effective use of DMA engines, clock management, and sleep states
• Proficiency in Python
• Experience with Git, GitHub, and the GitFlow process including pull requests, code reviews, and branches
• Some project management experience, particularly managing cross‑functional teams
• Personnel management and mentorship abilities, although will not be a manager immediately
• Experience with translating high‑level product needs into detailed firmware requirements and architectural specifications

PREFERRED SKILLS

The following areas represent where the candidate could grow over the long term. Any candidate should have experience in at least some of them.

• Standard and lower‑power radio protocols (Wi‑Fi, Bluetooth, ZigBee/other 802.15.4, ANT, etc.)
• Signal processing, such as Fourier Transforms, PSD, filters, and resampling
• Experience with Linux or SBCs like Raspberry Pi
• Familiarity with circuit simulation tools such as LTSPICE
• Schematic capture and PCB layout (Altium)
• Experience with smart materials such as piezoelectric actuators or piezo sensors
• Low‑power hardware design
• Building projects with CMake
• Experience writing detailed technical reports and/or proposals
