Spacecraft AIT Engineer (RF & Communications Systems)

WHO ARE WE?

Sateliot is a Barcelona-based Startup in the New Space sector, becoming the first satellite telecommunications operator that will provide global and continuous connectivity to all the elements that will make up the massive Internet of Things (IoT) universe under the 5G protocol.

In order to do so, Sateliot is launching a constellation of last generation nanosatellites, located at low altitude that act as mobile towers. Sateliot is the perfect complement for large telecommunications companies by providing them with the necessary infrastructure where terrestrial technologies do not arrive.

YOUR MISSION

As a Spacecraft AIT Engineer (RF & Communications Systems) at Sateliot, you will be both hands-on in the early phases and responsible for building out the processes and procedures over time. You will work closely with design, systems, and quality teams to ensure our spacecraft are built and tested to meet mission and schedule requirements. This is a hands-on engineering role ideal for someone who thrives in a fast-paced environment and is passionate about building space hardware from the ground up.

YOUR MAIN FUNCTIONS

Plan and execute integration campaigns, including mechanical, electrical, and harness integration activities.

Maintain accurate and complete build/test documentation and ensure proper use of ERP, MES and documentation systems.

Troubleshoot integration and test issues, perform root-cause analysis, and implement corrective actions.

Set up and operate test equipment for:

Functional testing

Environmental testing (vibration, thermal-vacuum)

RF and communications testing

Develop test setups and automation scripts (Python or similar) for verification and integration testing.

Support non-conformance investigations (NCRs), implement corrective actions, and drive closure.

Support launch campaign preparation, spacecraft close-out, and final verification activities.

Participate in MAIT activities for the Tritó satellite program and collaborate closely with MAIT Technicians.

Working knowledge of Linux and scripting (Python preferred).

Familiarity with RF Engineering test equipment and/or SDR-based systems.

Solid understanding of RF systems (signal chain, link behavior, integration impacts).

Comfortable working in cleanroom environments and handling flight hardware.

Strong problem-solving mindset, documentation discipline, and ability to work cross-functionally.

Experience with environmental testing: TVAC, vibration, thermal, EMC/EMI.

Experience with smallsat/newspace MAIT processes

Previous experience using MES systems in a production environment

Knowledge of ECSS or other (e.g. NASA) standards

Knowledge of space-grade parts sourcing and associated compliance strategies

Experience with certified quality management systems (e.g. ISO9000)

Hands-on experience integrating spacecraft subsystems and flight hardware

Previous experience developing/configuring SDR systems using GNU Radio or similar.
