Location: Luxembourg

Contract: Full-time, Permanent

Sector: Space Systems / Embedded & Real-Time Electronics

Role Overview

We are looking for a Senior Firmware / Embedded Software Developer to design and implement low-level, resource-efficient firmware running on microcontrollers and embedded processors. The role focuses on bare-metal and real-time software for control, signal processing, and hardware interaction in mission-critical systems.

You will work closely with system architects, electronics (PCB) engineers, and multidisciplinary engineering teams to translate system requirements into robust, maintainable firmware solutions.

Key Responsibilities

• Translate system-level requirements into detailed firmware requirements and architectures
• Define firmware designs and negotiate technical solutions with system architects and adjacent engineering teams
• Analyse, adapt, and integrate existing internal or open-source software to meet project needs
• Design and implement bare-metal firmware, including bootloaders and low-level services
• Develop real-time application-level software such as:
• Control state machines
• Signal processing blocks
• Timing, synchronization, and waveform generation
• Write application-level test benches and support verification activities
• Debug low-level firmware in close collaboration with electronics / PCB design engineers
• Maintain high-quality, readable, and maintainable code under version control (Git)
• Produce clear and structured technical documentation

Required Skills & Experience

• Bachelor’s or Master’s degree in Electronic Engineering, Computer Science, or a related field
• Minimum 5 years of experience in firmware and embedded software development
• Strong proficiency in C and C++
• Solid experience with ARM-based microcontrollers and processors, such as:
• STM32 families
• NVIDIA Orin platforms
• Proven experience writing bare-metal firmware for ARM architectures
• In-depth knowledge of embedded communication interfaces:
• I²C, SPI, UART, CAN (from PHY to application level)
• Hands-on experience debugging firmware using electronic lab equipment (oscilloscopes, logic analysers, etc.)
• Experience using and maintaining projects under Git version control
• Ability to take technical leadership on firmware-related activities

Languages

• English: Upper Intermediate or higher (required)
• French: Preferred

What We Offer

• Opportunity to work on advanced embedded systems for space applications
• Technically challenging projects with real hardware impact
• Collaborative, international engineering environment
• Competitive compensation and benefits
