Wanna join the adventure?
As an RF Systems Engineer at Loft Orbital, you will play a pivotal role in the integration of RF subsystems for our high-reliability satellite systems. You work with our RF team across campuses to collaboratively develop, integrate, and test sub-system and system-level solutions for our satellites. Your expertise will be critical in ensuring the success of our space mission.
You’ll join a talented, multi-disciplinary team working on the latest space technology, where your contributions will directly shape the future of space missions. This is an exciting opportunity to innovate, collaborate, and make a significant impact on mission-critical systems.
About this Role:
- System-Level RF Architecture & Design - Contribute to the definition of end-to-end RF system architecture and requirements, ensuring compatibility with mission constraints and performance goals.
- End-to-End Performance Analysis - Perform RF link budget analysis and system-level trade-offs to evaluate performance under various mission scenarios.
- Requirements Engineering / Traceability - Support requirements definition, flow-down, and traceability from mission-level needs to RF subsystem specifications.
- Test Campaign Support - Support the execution of RF test campaigns with our AIT teams, including test planning, documentation, and reporting of verification results.
- Scripts, Tools and Simulation - Ability to develop scripts and low-level software for debugging and test purposes (proficiency in Python and C is a strong asset). Utilize modeling and simulation tools (e.g., MATLAB, CST, ADS) to validate designs and predict system performance.
- Cross-functional Communication - Act as a technical interface between RF, software, mechanical, system, Ground and AIT teams to ensure smooth integration and alignment with program objectives.
Must Haves:
- Bachelor’s degree in Electrical Engineering, Aerospace Engineering, or a related field. Master’s degree preferred
- 2+ years of experience in Radio Frequency subsystem integration
- Proven experience in RF system integration, debugging and performance analysis
- Demonstrated autonomy in leading system and SW integration
- Knowledge of S-band and X-band frequency communications
- Excellent communication and teamwork skills
Nice to Haves:
- Experience in Signal Processing algorithms
- Proficiency in link budget calculations and antenna simulations
- Familiarity with design principles related to EMI shielding, grounding, and RF signal integrity
- Experience with simulation tools for EMI/EMC and RF analysis.
- Experience using CST (RF Simulation), ADS (design) tools.

- Relocation assistance to Toulouse when applicable
*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.
