Embedded Software Engineer H/F - 31

Wanna join the adventure?
As a member of our Embedded Systems Team, you will contribute to the embedded software design and development of our satellite electronic payloads-cutting-edge systems advancing the state of space-as-a-service. Our work pushes the boundaries of in-space compute, RF communications, software-defined payloads, and more. You'll collaborate closely with experienced engineers to bring these ideas to life and see your work launched into orbit.
About this Role:

- Design and implement high-quality embedded software for satellite systems, following best practices for modularity, maintainability, testability, and efficiency
- Develop and maintain interface drivers, data handling, and networking capabilities
- Support SW/FW/HW integration to deliver fully functional software solutions
- Write and maintain unit tests and component tests; contribute to CI pipelines
- Participate in hands-on board bring-up, debugging, and system-level testing
- Collaborate with cross-functional teams including hardware, systems, and test engineers

Must Haves:

- 4+ years of experience writing C or C++ for embedded systems (Embedded Linux)
- Working knowledge of Linux systems, including kernel concepts, device drivers, or BSPs
- Experience with local and remote debugging tools and workflows (e.g., gdb)
- Familiarity with hardware interfaces and communication protocols (e.g., UART, DMA, Ethernet, LVDS, SpaceWire)
- Experience using Linux build and cross-compilation toolchains (e.g., Yocto, Buildroot)
- Exposure to common processor architectures such as ARM-based SoCs
- Strong written and verbal communication skills
- Curious, resourceful, and comfortable working on novel technical problems
- Ability to take ownership of tasks while collaborating effectively within a multi-disciplinary team
- Willingness to learn, adapt, and grow into new technologies and responsibilities

Nice to Haves:

- Experience with aerospace, space systems, or other safety-critical software
- Exposure to virtualization technologies (hypervisors and/or containers)
- Familiarity with radiation effects or Single Event Upset (SEU) mitigation concepts

- Cross-office travel opportunities between San Francisco, Colorado, and Toulouse to learn from our differences
- Company and team off-sites and many other events to work & celebrate together
- Relocation assistance to Toulouse when applicable

*Research shows that while men apply to jobs where they meet an average of 60% of the criteria, women and other underrepresented people tend to only apply when they meet 100% of the qualifications. At Loft, we value respectful debate and people who aren't afraid to challenge assumptions. We strongly encourage you to apply, even if you don't check all the boxes.
Who We Are
Loft: Space Made Simple.
Founded in 2017, Loft provides governments, companies, and research institutions with a fast, reliable, and simple way to deploy missions in orbit.
We integrate, launch, and operate spacecraft, offering end-to-end missions as a service across Earth observation, IoT connectivity, on-orbit AI, national security missions, and more. Leveraging our existing space infrastructure and an extensive inventory of satellite buses, Loft is reducing years-long integration and launch timelines to months. With more than 30 missions flown, Loft's flight heritage and proven technologies enable customers to focus on their mission objectives.
With a growing fleet on track to reach 30 satellites by 2027, we are scaling up quickly across our offices in San Francisco, CA Golden, CO and Toulouse, France to meet accelerating demand for space infrastructure.
As an international company your resume will be reviewed by people across our offices so please attach a copy in English.
