Avionics System Senior Engineer - Flight Communication (Radio Frequency)

Here at The Exploration Company, we are developing, producing, and operating Nyx, a modular and reusable space orbital vehicle that can eventually be refuelled in orbit and that can carry cargo - and potentially humans in the longer run.

The ideal candidate will have a deep understanding of RF communication principles and experience with spacecraft communication systems, particularly in the challenging environment of space.

Key Responsibilities

• Design and development of a Radio Frequency communication systems for a spacecraft in LEO that will communicate with both the orbital systems and ground systems.

• Perform link budget analysis to ensure reliable communication throughout the mission,

• Specify antenna design and placement to optimize signal strength and reliability, accounting for spacecraft dynamics and orientation.

• Analyze and mitigate potential Radio Frequency interference issues with other communication systems (Space stations, Earth-based stations, other satellites).

• Define communication protocols and modulation schemes to support real-time data and telemetry/telecommand transmission between the spacecraft and remote systems.

• Conduct testing and validation of the RF communication system, including simulations, hardware-in-the-loop (HIL) testing, and in-orbit testing post-launch.

• Ensure compliance with regulatory standards for RF communication in space, including coordination with agencies like NASA, ESA, and ITU.

• Document technical designs, analyses, and test results, providing regular updates to the project team.

• Support the mission operations team in troubleshooting and resolving any communication issues that arise during the spacecraft’s mission

Required Qualifications

• Bachelor's or Master’s degree in Electrical Engineering, Telecommunications, Aerospace Engineering, or a related field.

• 5+ years of experience in RF communication system design, preferably in aerospace or satellite communication environments.

• Proficiency in RF circuit design, including amplifiers, mixers, and filters.

• Expertise in antenna theory and design for space applications.

• Experience with link budget analysis, modulation techniques, and coding schemes for space communication systems.

• Knowledge of spacecraft communication protocols and standards (e.g., CCSDS).

• Experience with RF simulation tools (e.g., CST, HFSS, MATLAB, or similar).

• Understanding of orbital mechanics and their impact on RF communication (e.g., Doppler shift).

• Familiarity with space mission lifecycle, including design, integration, testing, and operations phases.

• Knowledge of space-qualified hardware and environmental challenges (radiation, thermal, vacuum) is a plus.
