Test Engineer, RF

Wanna join the adventure?

As our new Test Engineer –RF/Spacecraft AIT, you will play an important role in the integration, testing, and validation of spacecraft systems and RF components supporting Loft's space missions.

We are looking for a hands-on Test Engineer with a strong foundation in electrical or spacecraft testing, some exposure to RF systems, and an interest in further developing their RF testing expertise.

You don't need to be an RF expert to start in this role, but along the way, we’ll help you develop those skills. We're looking for someone who brings solid testing and electrical fundamentals, strong troubleshooting skills, and a willingness to learn and grow within our spacecraft AIT environment.

About the Role:

• Develop, execute, and maintain test plans and procedures for spacecraft systems, RF subsystems, and electrical components.
• Perform hands-on functional, integration, and validation testing of spacecraft hardware.
• Support the assembly, integration, and testing of RF components and subsystems.
• Troubleshoot electrical, RF, and system-level issues identified during testing.
• Work with RF engineers and other technical specialists to develop deeper expertise in RF testing methodologies and equipment.
• Operate and become proficient with RF test equipment, such as spectrum analyzers, vector network analyzers (VNAs), and signal generators.
• Analyze test results, identify anomalies, document findings, and support corrective actions.
• Support spacecraft environmental testing activities, including thermal vacuum, vibration, and EMI/EMC testing, as needed.
• Collaborate with electrical, mechanical, RF, and systems engineers to ensure successful spacecraft integration and testing.
• Contribute to improvements in test procedures, equipment, automation, and overall testing efficiency.
• Support spacecraft electrical checkout and functional verification throughout the AIT process.

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.
