Sr. Communications Payload Avionics Engineer

Spin Launch is pioneering a new era of scalable space infrastructure. Following years of innovation in alternative launch systems, we’re now applying that same disruptive mindset to orbit—developing Meridian Space, a ground-breaking broadband satellite constellation built for rapid deployment and low-cost global coverage. With backing from industry leaders, Spin Launch is positioned to deliver a fully integrated ecosystem of launch, satellite, and connectivity services.

Join us in our mission and be an integral part of a close-knit, collaborative team that strives in a fast-paced, innovative environment. This is an on-site position located at our Long Beach, CA headquarters.

You are responsible for the design and development of the satellite communication payload avionics of the Meridian Space constellation. This includes radio systems, antenna signal interfaces, waveguide design, and antenna and radio control systems. As part of a small team tackling ambitious challenges, you’ll take full ownership of the end-to-end success of your hardware in orbit - driving every aspect of development, from design to fully-integrated, space-ready systems.

Responsibilities include, but are not limited to:

• Designing and developing communication payload avionics systems, including RF front-ends, transceivers, modems, and antenna interfaces
• Developing and reviewing hardware schematics, PCB layouts, and embedded control architectures for communication electronics
• Leading integration, testing, and qualification of payload avionics at subsystem and system levels (EMC, vibration, thermal, etc.)
• Participating in failure analysis, root cause investigations, and continuous improvement of communication hardware designs
• Performing link budget analysis, system modeling, and simulation for space-to-ground and inter-satellite communication links

• Graduate degree in Electrical Engineering or related field
• Minimum of 4 years of broad experience doing RF/Analog circuit design and board layout using the relevant tools
• General electrical hardware design experience (Power, DC, digital design)
• Experience modeling, designing, and testing radio subsystems, preferably for satellite payloads and at a system level
• Proficiency in hardware design tools (Altium Designer, Cadence, or equivalent)
• Experience using HFSS, CST, or similar RF simulation tools
• Ability to perform bench-level analog/power bring-up and troubleshooting using analog and digital test equipment like spectrum analyzers, network analyzers, and vector signal generators
• Strong understanding of modulation schemes, RF architectures, and signal integrity principles
• Strong verbal and written communication skills

• Experience with RF component characterization
• Experience with LEO/MEO/GEO satellite communication payloads
• Understanding of radiation effects and mitigation techniques in space environments
• Experience designing, manufacturing, and testing space flight hardware
• Antenna or satellite system design experience
• Expertise in automating test equipment
• Experience using analytical methods for signal integrity analysis
