ELECTRICAL ENGINEER III, PCB Design & Avionics

Parallax Space is building critical mission infrastructure to enable rapid, reliable, and scalable access to space. We partner with commercial, civil, and national security customers to deliver high-performance satellite components, integrated payload systems, and mission capabilities that close critical gaps in modern space architecture. Our model combines advanced engineering, mission execution, and scalable manufacturing to deliver high-TRL products and flight-ready systems at speed. We are building the infrastructure backbone for the next generation of space systems. Position Overview Parallax Space is seeking a mid-level Electrical Engineer with a strong focus on PCB design to support the development of spacecraft electronics, payload electronics, avionics, test hardware, and mission-enabling electrical systems.
