Senior RF Systems Engineer

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.

• 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.
• EMI/EMC Knowledge – Identify and mitigate potential EMI/EMC issues through design reviews and validation testing.
• 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.

• Bachelor’s degree in Electrical Engineering, Aerospace Engineering, or a related field. Master’s degree preferred.
• 5+ years of experience in Radio Frequency subsystem integration.
• Proven experience in RF system integration, debugging and performance analysis.
• Proficiency in link budget calculations and antenna simulations.
• Demonstrated autonomy in leading system and SW integration.
• Knowledge of S-band and X-band frequency communications.
• Excellent communication and teamwork skills.

• Experience in Signal Processing algorithms.
• 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.

• 100% company-paid medical, dental, and vision insurance option for employees and dependents.
• Flexible Spending (FSA) and Health Savings (HSA) Accounts offered with an employer contribution to the HSA.
• 100% employer paid Life, AD&D, Short-Term, and Long-Term Disability insurance.
• Flexible Time Off policy for vacation and sick leave, and 12 paid holidays.
• 401(k) plan and equity options.
• Daily catered lunches and snacks.
• International exposure to our team in France.
• Fully paid parental leave; 14 weeks for primary caregiver and 10 weeks for secondary caregiver.
• Carrot Fertility provides comprehensive, inclusive fertility healthcare and family-forming benefits with financial support.
• Off-sites and many social events and celebrations.
• Relocation assistance 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.
