Embedded Software / Firmware Engineer

Your role in the team

• Own the low-level software layer of our autonomy platform across drones, payload and ground systems. Your work defines the fieldability, robustness and performance of our core product.
• As Embedded Software / Firmware Engineer, you'll own the low-level software foundation across our embedded platforms - from bring-up and driver development to deployment tooling and in-field update infrastructure. You'll work across diverse compute platforms, enabling new sensors, cameras, AI accelerators and networked peripherals and turning prototypes into robust, fieldable systems.
• This is a hands-on, on-site role in our prototyping and test space, with optional travel for field trials and partner testing. You'll work closely with our hardware design and testing teams while collaborating with our world-class AI software team to ship vertically integrated solutions fast. Your contributions will directly shape system architecture and hardware design, and the systems you support will move quickly from bench to real-world testing and front-line deployment at scale reshaping Europe's defense capability.

Responsibilities

• Requirements & Bring-Up: Translate system needs into low-level software architecture and bring new boards and subsystems to life across Jetson, Arm, and STM32 platforms.
• Drivers & Interfaces: Develop and maintain drivers and hardware-facing software for sensors, cameras, AI accelerators and communication networks.
• Kernel & System Layer: Work across embedded Linux, kernel and device-tree configuration, BSP-level integration and board bring-up to create stable, maintainable foundations.
• Flash, Boot & Deploy: Build and refine flashing, booting, and serial deployment tooling for development, production, update, and recovery workflows.
• Troubleshoot & Iterate: Debug on the bench, isolate failures quickly, improve performance and stability, iterate until systems are ready for field use.
• Integrate & Maintain: Support system integration across aircraft platforms, work closely with hardware engineers and continuously improve performance, reliability and long-term maintainability.

Our expectations:

Qualifications

• M.Sc. or higher in Computer Engineering, Electrical Engineering, Robotics, Embedded Systems or a related field.
• You're strong in C and Python and comfortable shipping real systems on embedded Linux in robotics, automotive or other hardware-adjacent environments.
• You're comfortable with board bring-up, serial consoles, flashing workflows, boot issues, hardware-near debugging, and systematic troubleshooting on real hardware.
• You know how to make software not just functional, but deployable, maintainable and robust under real-world conditions.
• You know how to validate low-level software on real hardware through structured debugging, integration testing, and release-oriented validation.
• Most importantly, you're structured, fast-moving and mission-driven. You don't wait for perfect specs but take ownership and iterate until it works.
• You thrive in a high-impact startup environment and are comfortable with a demanding execution pace, including sustained high intensity around critical milestones.

Experience

• You bring 2+ years of hands-on experience in low-level software or firmware development for embedded systems; we're equally interested and will reward more senior engineers who want to work deeply hands-on.
• You have practical experience with hardware interfaces and protocols such as I2C, SPI, CAN, Ethernet, and MIPI-based camera interfaces.
