Firmware Engineer lll

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.

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

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

  32, EFM
  32, etc.) are highly preferred
• Experience working on devices without an operating system and interfacing with peripherals directly
• Ability to read schematics, circuit diagrams, and PCB layouts
• Expert debugging skills using SWD/JTAG, protocol/logic analyzers, and oscilloscopes
• Effective verbal and written communication skills

The following areas are important and will be used in this position’s projects over the next year. The ideal candidate will have experience in these areas, but we will not reject applicants for lack of experience in these areas.

• Experience with STM
  32 microcontrollers
• Wi-Fi / lwIP networking in low‑power and embedded contexts like the ESP
  32 platform

• Standard and lower‑power radio protocols (Wi‑Fi, Bluetooth, Zig Bee/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
