Wanna join the adventure?

As our new RF AIT (Radio Frequency Assembly, Integration, and Test) Engineer, you will play a pivotal role in the development, assembly, integration, and testing of RF (Radio Frequency) systems and components for Loft space missions. This role requires a strong background in RF engineering, electrical engineering, and space technology.

• Lead the assembly and integration of RF subsystems and components into the spacecraft.
• Ensure proper installation, wiring, and connectivity of RF hardware according to design specifications.
• Develop test plans and procedures for RF systems and components.
• Conduct comprehensive RF tests to verify system performance, including sensitivity, signal-to-noise ratio, and frequency response.
• Troubleshoot and resolve RF hardware issues during testing.
• Prepare RF hardware for environmental testing, including thermal vacuum testing, vibration testing, and electromagnetic interference (EMI)/electromagnetic compatibility (EMC) testing.
• Analyze and report on environmental test results to ensure RF systems meet specified requirements.
• Collaborate with RF system architects and design engineers to perform system analysis and simulations for performance optimization.
• Work closely with cross-functional teams, including electrical engineers, mechanical engineers, and system engineers, to integrate RF systems into spacecraft successfully.
• Hands-on experience with space hardware and spaceflight antennas, with a strong understanding of design intent.
• Proficiency in test engineering, including test design, validation, execution, and troubleshooting.
• Experience with tests such as EMI/EMC, GNC GPS testing, and TTNC (tracking telemetry and control).
• Knowledge of relevant software for testing and analysis.
• Familiarity with electrical check-out procedures and environments, though emphasis lies more on rigorous testing rather than environmental testing.

State law requires us to tell you the base compensation range for this role, which is $115,000 - $180,000 per year. This is determined by your education, experience, knowledge, skills, and abilities. The salary range for this role is intentionally wide as we evaluate individuals based on their unique experience and abilities to fit our needs. Most importantly, we are excited to meet you, and see if you are a great fit for our team. What we  can’t  quantify for you are the exciting challenges, supportive team, and amazing culture we enjoy.

 * 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 \u007C Golden, CO \u007C 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.

We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses and identifying potential inconsistencies or verification signals in application materials based on available information. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.
