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, a global supplier to automotive, aerospace, defense, and industrial markets. Midéis R&D works towards vehicle electrification and distributed industrial sensing, especially 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. We are a great place to learn, as well as a place that rewards people who have drive and their own ideas. Midéis has a small company feel with about 60 people working out of our Woburn office, including over 20 engineers divided between software, electrical, mechanical, and aerospace. Midéis has successfully transitioned a number of its R&D programs to successful product lines ranging from wireless data loggers to critical safety seals used on US 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

• BS(E) in Electrical Engineering, Electronics & Communications Engineering, Computer Science, or similar, required.
• 6+ years firmware or embedded software experience, required.

Requirements

• Must be a US person (citizen or permanent resident).
• Software design and architecture experience. C is highly preferred; C++ and similar languages are also acceptable.
• Interest in project management.
• Experience with microcontrollers and direct access to peripherals. ARM Cortex‑M series processors (e.g., STM32, EFM32) 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.

Highly Preferred

• Experience with STM32 microcontrollers.
• Wi‑Fi/lwIP networking in low‑power and embedded contexts such as the ESP32 platform.
• 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 translating high‑level product needs into detailed firmware requirements and architectural specifications.

Preferred Skills

• Advanced object‑oriented and software architecture skills.
• Standard and low‑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 single‑board computers 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.
