Key responsibilities include:

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) that interfaces with space vehicles under Assembly, Integration & Tests, allowing Validation and Verification of spacecrafts and their software before their launch campaigns.
Develop tools and frameworks that allow teams to simulate faults, edge cases, and mission scenarios that are difficult or costly to reproduce with physical hardware alone.
Work closely with systems, software, hardware, and operations teams to understand evolving test requirements and integrate feedback into the platforms.
Maintain and extend test infrastructure to support continuous integration (CI) pipelines, ensuring every code change is validated with realistic system-level tests.
Troubleshoot complex system issues spanning software, embedded hardware, networking, and system configuration.

Our culture at Loft Orbital promotes collaboration and ownership among our developers, fostering efforts hand in hand with other teams, internally and externally.

Must Haves:

Proficiency in Python (3.9+) for building test automation frameworks, device drivers, or test orchestration tools.
Experience containerizing applications with Docker.
Familiarity with at least one modern CI tool (e.g., Jenkins, GitLab CI, Buildkite, CircleCI) and integrating test pipelines.

Nice to Haves:

Experience designing or automating complex HIL/SIL testbed, signal conditioning, fault injection, or hardware emulation.
Experience with “Infrastructure-as-Code” systems, specifically NixOS.
Familiarity with networking simulation tools (e.g., network emulators, virtual switches) for testing data flows under realistic mission constraints.
Interest or experience with hardware test automation frameworks (e.g., custom Python-based test rigs).

*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.
