About Aerospacelab

Our mission is supported by an ambitious vertically integrated approach: design & manufacture of small satellites combined with development of earth observation services.

Since its creation in 2018, the company has already grown substantially. Our team gathers more than 25 engineering expertise, from hardware design to software development & data science.

In 2026, Aerospacelab counts offices in Louvain-la-Neuve (Belgium), Toulouse (France), Lausanne (Switzerland) and US West Coast with more than 500 full-time employees, with the ambition to position itself as the European leader in small satellites.

Your mission

Turn security requirements into concrete technical implementations across our satellite, working side by side with the teams who build and run them.
Deploy and operate intrusion detection for our satellites and the log management chain behind it, including syslog configuration and log signing
Design and deploy our PKI: key ceremonies, HSMs, secret handling, certificate lifecycle, approval and revocation processes.
Understand the protocols commonly used on satellites well enough to define where and how security controls apply to them.
Secure embedded systems, including FPGA-based hardware, in collaboration with the system and hardware teams.
Understand the operating systems used on board and on the ground (RTOS, embedded Linux) and their security implications: isolation, secure boot, hardening and update mechanisms.
Explain what needs to be implemented and why, so that security measures get adopted rather than worked around.

What we are looking for

An MSc (or equivalent experience) in cybersecurity, computer science, electronics or a related field.
Hands-on experience implementing security on embedded systems, ideally including FPGA, with a solid grasp of system architecture.
Practical experience with log management solutions and with PKI components (HSMs, certificate management, key ceremonies).
The ability to translate requirements into implementations tailored to a specific context
Clear communication: ability to explain why a control matters to the engineers who implement it, and to tell a requirement from its implementation.
Background in the satellite industry, with a feel for the constraints of space systems.

Nice to have

Experience with intrusion detection for space systems
Background in the satellite industry, with a feel for the constraints of space systems.
Knowledge of security frameworks and standards (CRA, Sparta, ISO27K, IEC62443)
Experience in vulnerability management: scanning, CVSS-based prioritisation, patch and remediation tracking, and SBOM analysis.

Why join us

You’ll implement security on real satellites, with a direct line from your design choices to systems flying in orbit. You’ll work in a fast-moving team where your work is visible.
