Meridian is building a fundamentally new model for sovereign space infrastructure—delivering complete, owned Low Earth Orbit (LEO) satellite constellations that provide governments and commercial operators with full control, assured access, and sovereign communications capability at a fraction of the cost of developing these systems independently. Backed by leading venture capital investors and engineering partners, we are rapidly scaling the design, production, and deployment of the satellites, ground systems, and network infrastructure that will power Meridian's next-generation constellations. Joining Meridian means working at the forefront of one of the world's most ambitious space programs underway today - designing and building constellations that will put sovereign connectivity within reach of nations and operators worldwide. You'll be part of a close-knit, collaborative team that thrives in a fast-paced, innovative environment, where your work directly advances the design, development, and deployment of satellite constellations that governments and enterprises around the world will depend on for secure, resilient, and sovereign connectivity. Your Mission on the Team: You are responsible for the design and development of the analog RF systems and supporting avionics in the satellite communication payloads of Meridian Space constellation. That includes: • Transponder RF chains (Amplifiers, filters, mixers) • Means of controlling transponder functions • Transponder power supply avionics • Radio-to-antenna interface design Basic Qualifications: • Graduate degree in Electrical Engineering or related field • Minimum of 5 years of experience designing analog RF systems, with hands-on circuit design and board layout using industry-standard EDA tools • Experience designing RF signal chains incorporating amplifiers, filters, and mixers, using circuit simulation tools such as ADS or Microwave Office • Experience designing power supply avionics for RF or analog payloads • Ability to perform bench-level RF and analog bring-up and troubleshooting using spectrum analyzers, network analyzers, signal generators, and other RF test equipment • Strong verbal and written communication skills Preferred Qualifications: • Experience designing transponders or transponder-like RF chains for satellite communication payloads • Experience with radio-to-antenna interface design and passive RF/microwave components (waveguides, diplexers, couplers, filters), including 3D EM simulation in HFSS, CST, or similar • Experience designing, manufacturing, and testing space flight hardware, including managing radiation effects (TID, SEE mitigation, part selection) • General electrical hardware design experience across power, DC, and digital domains • Experience with antenna range or anechoic chamber testing and RF component characterization • Expertise in automating RF test equipment and reducing measurement data using Python, MATLAB, or similar tools ITAR Requirements Meridian is required by the U.S. Government to comply with various space technology export regulations including the International Traffic in Arms Regulations (ITAR).
