About The Position

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. Weâre intentional, weâre unapologetically curious and weâre 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-generation 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.

Requirements

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.

Nice To Haves

Experience with satellite or spacecraft avionics design and qualification (EM/QM/FM build cycles).
Background in non-volatile memory technologies (Flash, MRAM, FRAM) and in-system programmability.
Exposure to power supply design and power integrity analysis for digital boards.
Experience with design for radiation reliability and single-event effects mitigation at the board level.
Familiarity with signal integrity simulation tools (HyperLynx SI/PI, Ansys, ADS).
