Principal Embedded Engineer - Space Systems

Hubble Network•Seattle, WA

8d•Onsite

About The Position

Hubble Network is seeking an experienced Principal Embedded Engineer to architect and implement software for their satellite systems. This is a hands-on role where you will work closely with hardware, RF, and operations teams to develop high-reliability embedded software that powers their constellation. The engineer will act as a technical leader, translating system-level requirements into robust, efficient embedded solutions for the space environment. This position offers an opportunity to work across the full embedded stack, from low-level device drivers to application-level software managing satellite operations, and contribute to the architecture of their next-generation satellite platform.

Requirements

8+ Years of Experience: Proven track record of delivering embedded systems for production hardware, preferably in Aerospace, Defense, or other high-reliability domains.
Experience acting as a technical leader and trusted mentor, fostering engineering excellence through hands-on collaboration and coaching.
Expert-Level C Programming: Deep understanding of C for embedded systems, including memory management, real-time constraints, and optimization techniques.
Expert-Level Python: Strong Python skills for scripting, automation, test frameworks, and ground system integration.
Embedded Linux Proficiency: Solid experience with embedded Linux (kernel configuration, device drivers, build root/Yocto, or similar).
Hardware Interface Experience: Demonstrated ability to work with SPI, I2C, UART, Ethernet, and other common protocols. Experience with ADCs, DACs, and memory interfaces (DDR).
Hardware Debug Skills: Comfortable using oscilloscopes, logic analyzers, and JTAG debuggers to troubleshoot hardware and software issues.
Must be a U.S. citizen, lawful permanent resident ('green card holder') as defined by ITAR.

Nice To Haves

Space Systems: Experience designing for the space environment, including radiation hardening techniques, thermal management, and understanding of single-event effects.
FPGA Integration: Experience interfacing with or developing alongside FPGAs, including familiarity with common communication interfaces (AXI, PCIe, custom parallel buses), register-mapped peripheral access from embedded Linux or bare-metal environments, and collaborative bring-up with digital design engineers.

Responsibilities

Write high-quality, maintainable code in both Python and C for satellite command scripts and performance-critical embedded applications.
Design, implement, and maintain embedded Linux systems for satellite payloads, including kernel configuration, driver development, and system optimization for resource-constrained space hardware.
Develop and debug device drivers for common interfaces (SPI, I2C, UART, Ethernet) and peripherals including ADCs, DACs, DDR memory controllers, and custom hardware.
Contribute to the design and implementation of satellite flight software, including command & data handling, telemetry systems, and autonomous operations.
Lead board bring-up activities for new hardware, working closely with electrical engineers to validate designs, debug interfaces, and commission new systems.
Design software with awareness of space-specific challenges including radiation effects (SEUs, latch-up), thermal constraints, and power budgets.
