Software Engineer - Flight and Embedded

EON is building the highest-throughput point-to-point data transport network ever deployed in space. They are seeking a Software Engineer to own the flight and embedded stack, developing firmware and supporting hardware integration for their optical payload and ground terminal.

What you'll do:

• Develop embedded firmware in C/C++ for the terminal and payload electronics: drivers, board support, and deterministic real-time execution on microcontrollers and SoCs
• Build the payload application layer: commanding, telemetry, fault detection and management, and the software interface to the bus
• Implement control loops in real-time code, carrying designs from the GNC and Lasercom PAT seats into terminal and flight software
• Support board bring-up with the EE seats, writing the low-level drivers (I2C, SPI, UART, Ethernet) that make new hardware usable
• Instrument everything for observability: logging, telemetry, and diagnostics that serve integration, test, and operations
• Stand up the embedded toolchain: build systems, version control, CI, and hardware-in-the-loop test as the stack matures toward flight
• Define the path from demonstrator software to flight rigor: fault handling, safing behavior, and update mechanisms

What they're looking for:

• Bachelor's or advanced degree in computer science, computer engineering, electrical engineering, or a related discipline
• Embedded development depth in C or C++, spanning bare-metal and RTOS environments
• Hands-on hardware bring-up experience, debugging across software and hardware with oscilloscopes, logic analyzers, and JTAG
• Low-level peripheral and driver experience (I2C, SPI, UART, ADC, Ethernet)
• Python for tooling, test automation, and data analysis
• Comfort moving fast and making sound calls without complete data
• Flight software experience: cFS, F Prime, CCSDS protocols, or similar frameworks
• Real-time control loop implementation alongside controls or GNC engineers
• FPGA SoC platforms (Zynq or similar), including the gateware-to-software interface
• Fault management and FDIR design for spacecraft or high-reliability systems
• Hardware-in-the-loop test infrastructure
• Telemetry pipelines and ground-interface protocols

Benefits:

• Company stock options for FTEs (employee-owned belief).
• Comprehensive medical, vision, and dental insurance with significant cost covered by the company for yourself and dependents.
• Paid parental leave.
• Flexible PTO (3 weeks accrued vacation and 10 company holidays per year).
• Relocation assistance to Los Angeles available.
• A real equipment and lab budget.
• Location: Culver City, CA (onsite).
