Tools & Technologies: * Altium Designer (schematic capture and layout review) * HyperLynx SI, SI/PI, and Full-Wave (signal and power integrity) * SPICE-based circuit simulation * FPGA vendor toolchains (for interface bring-up and debug), This is a full time, exempt position, based out of our Saratoga office. The total compensation packaged will be determined by various factors such as your relevant job-related knowledge, skills, and experience. We are redefining how satellites are designed, manufactured and used-so we're looking for candidates with passion, deep knowledge and direct experience on LEO satellite component development, design and in-orbit activities. If that's your experience - then we'll be immediately wow-ed. E-Space is not currently able to provide employment sponsorship for candidates who do not hold work authorization for the location of this role. ## Description Job DescriptionJob DescriptionReady to make connectivity from space universally accessible, secure and actionable? Then you've come to the right place! E-Space is bridging Earth and space to enable hyper-scaled deployments of Internet of Things (IoT) solutions and services. We are building a highly-advanced low Earth orbit (LEO) space system that will fundamentally change the design, economics, manufacturing and service delivery associated with traditional satellite and terrestrial IoT systems. We're intentional, we're unapologetically curious and we're 100% committed to innovate space-based communications and deliver actionable intelligence that will expand global economies, protect space and our planet and enhance our overall quality of life. We are seeking experienced Digital Design Engineers to join our Satellite Avionics team. In this role you will own the electrical design of complex digital boards for a next- satellite constellation, including high-speed interfaces, FPGA integration, and mixed-signal subsystems. You will play a central role in delivering flight-qualified avionics hardware from concept through qualification., * Own schematic design and component selection for digital avionics boards, from concept through flight qualification. * Design high-speed SERDES interfaces (PCIe, JESD, gigabit links) and DDR4/DDR5 memory interfaces with proper timing closure. * Develop clocking architectures including PLL configuration, jitter management, and clock distribution networks. * Perform power budgeting and system-level power allocation across board subsystems. * Apply radiation-tolerant design techniques including SEU/SEE mitigation, TID considerations, and appropriate component derating. * Collaborate with FPGA engineers on support circuitry design, pinout planning, and power/layout requirements. * Drive board bring-up activities including configuration, interface verification, and structured debugging. * Participate in design reviews and cross-functional integration with RF, power, thermal, and mechanical teams.
