Firmware Developer

About the Role
We are looking for an experienced Embedded / Firmware Engineer to join a team developing advanced hardware systems used in high-performance engineering environments. The role focuses on designing and developing low-level software for microcontrollers operating in resource-constrained environments and responsible for real-time control and signal processing.

Responsibilities

• Translate system-level requirements into firmware-level specifications and collaborate with system architects and engineering teams to validate the design.

• Analyze, adapt, and integrate existing software solutions (internal or open source) to meet project needs.

• Develop bare-metal software for ARM-based microcontrollers, including bootloaders and low-level services.

• Implement real-time application logic such as control state machines, signal processing modules, timing systems, and waveform generators.

• Develop application-level test benches.

• Debug low-level firmware together with hardware engineers and PCB designers.

• Maintain clean, readable, and reliable code within version control systems.

• Prepare and maintain technical documentation for developed solutions.

Requirements

• Bachelor’s or Master’s degree in Electronic Engineering, Computer Science, or a related field.

• 5+ years of experience in firmware or embedded software development.

• Strong programming skills in C and C++.

• Experience working with ARM-based microcontrollers and processors (e.g., STM32 family, NVIDIA Orin).

• Hands-on experience writing bare-metal software for ARM platforms.

• Strong understanding of communication interfaces such as I2C, SPI, UART, and CAN from PHY to application level

• Experience working closely with hardware engineers on prototypes and debugging using electronic lab equipment.

• Understanding of version control systems and experience working with Git.

• Ability to lead engineering tasks and coordinate work with cross-functional teams including hardware, mechanical, optical, and software engineers.

• English – Upper-Intermediate level or higher. French is considered a plus.

What we offer

• Office-based position in Luxembourg (5 days per week)

• Relocation support

• 26 days of paid vacation

• Medical insurance and sick leave covered by the Luxembourg social system

• Stable working environment within a strong engineering team

• Healthy work-life balance without overtime policies
