Job summary

Loft Orbital is seeking a Test Infrastructure Engineer to design, build, and maintain advanced testbeds that mirror spacecraft systems. You will create HIL environments and EGSE interfaces to validate software and hardware before launches, while collaborating across systems, software, and operations teams.

You will drive automation with Python, Docker, and CI tooling, enabling scalable testing across our global sites in Toulouse and Golden, CO.

Qualifications

• 2+ years working with Linux systems, including configuration, debugging, and system-level troubleshooting.
• Strong understanding of networking fundamentals (OSI layers, packet analysis, TCP/IP and UDP).
• Hands-on experience with embedded systems or low-level hardware (Raspberry Pi, microcontrollers, etc).
• Proficiency in Python for building test automation frameworks, device drivers, or test orchestration tools.
• Experience containerizing applications with Docker.
• Familiarity with CI tools (e.g., Jenkins, GitLab CI, Buildkite, CircleCI) and integrating test pipelines.

Responsibilities

• Design, build, deploy, and maintain high-fidelity Hardware-in-the-Loop (HIL) testbeds that emulate spacecraft systems, sensors, and communication links.
• Design, build, deploy, and maintain Electrical Ground Support Equipment (EGSE) interfacing with space vehicles for Validation and Verification before launch campaigns.
• Develop tools and frameworks to simulate faults, edge cases, and mission scenarios that are hard to reproduce with physical hardware.
• Collaborate with systems, software, hardware, and operations teams to evolve test requirements and integrate feedback.
• Maintain and extend test infrastructure to support CI pipelines with realistic system-level tests.
• Troubleshoot complex system issues spanning software, embedded hardware, networking, and configuration.
