Embedded System Engineer in FRANCE

Company Description

VOLK is a specialized company in embedded systems design located in the Greater Paris Metropolitan Region. We focus on helping companies bring their ideas to life by creating fully functional prototypes and final products.

We are looking for a Senior Embedded Systems Engineer to work on cutting-edge IoT and embedded systems projects. This role is fully remote and is ideal for a freelancer/contractor who already has a registered company.

As part of the team, you’ll develop low-level firmware for MCUs, integrate with Zephyr RTOS, and work with Embedded Linux (Yocto, device trees, kernel customization). The projects will involve low-power wireless communication protocols (LPWAN, BLE, WiFi), security, and performance optimization.

If you’re passionate about real-time embedded development, open-source software, and Rust adoption in embedded, this is the perfect role for you!

• Develop firmware for microcontrollers (MCUs), optimizing for performance and power consumption.
• Work with Zephyr RTOS (or similar real-time operating systems).
• Develop software for low-power wireless protocols (LPWAN, BLE, WiFi).
• Integrate firmware with Embedded Linux (Yocto, device trees, kernel customization).
• Write high-quality, efficient code in C, C++, and Rust.
• Debug hardware/software interactions using oscilloscopes, logic analyzers, JTAG, GDB, OpenOCD.
• Implement secure boot, firmware update mechanisms, and low-power optimizations.
• Collaborate with hardware engineers on system bring-up and prototyping.
• Conduct code reviews and contribute to system architecture decisions.

✔ 5+ years of experience in embedded software development.

✔ Strong expertise in MCU peripherals (UART, SPI, I2C, ADC, DMA, PWM).

✔ Experience with Zephyr RTOS (or other RTOS like FreeRTOS).

✔ Knowledge of LPWAN (LoRa, NB-IoT), BLE, and WiFi communication protocols.

✔ Proficiency in C/C++ and understanding of real-time embedded systems.

✔ Enthusiasm for Rust in embedded development (or willingness to adopt it).

✔ Experience with Embedded Linux (Yocto, kernel/device tree configuration).

✔ Strong debugging and troubleshooting skills (GDB, OpenOCD, JTAG).

✔ Background in hardware design (schematics, PCB layout understanding).

✔ Preferably already operating as a freelancer with a registered company.

⭐ Work on innovative IoT and embedded Linux projects.

⭐ Be part of a team driving Zephyr RTOS and Rust adoption in embedded.

⭐ Fully remote role, offering flexibility and autonomy.

⭐ Opportunity to shape architecture decisions and influence product design.

⭐ Ideal for freelancers who want to work on impactful, challenging projects.

If you’re a seasoned embedded engineer excited about RTOS, Zephyr, firmware, and Embedded Linux, and you already operate as a freelancer with a registered company, we’d love to hear from you!
