Job description
About EON
EON is building the highest-throughput point-to-point data transport network ever deployed in space. Using free-space laser links in Medium Earth Orbit (MEO), we move petabytes of data between any two points on Earth as an alternative to subsea or terrestrial fiber. EON recently closed a $10.75M seed financing round led by Andreessen Horowitz and General Catalyst in their first-ever co-led space deal. EON is building out of its R&D center in Culver City.
Today, approximately 95% of the global internet travels through a few hundred subsea fiber-optic cables, infrastructure designed in the early 2000s that has gone largely unchanged. Demand for new fiber has never been higher, but laying it is extraordinarily difficult: permits, ocean geology, and geopolitical boundaries make every new cable a years-long, billion-dollar undertaking. That bottleneck is a liability with cables at constant risk of being cut, whether by accident or adversarial action, and no amount of ground-based investment can fully solve it.
The Role
Our optical payload and ground terminal run on embedded software: board-level firmware, the payload application layer, and the real-time code that closes control loops. We are seeking a software engineer to own the flight and embedded stack, from drivers and bring-up support on new boards through commanding, telemetry, and fault management on the payload. You'll partner with the GNC and Lasercom PAT seats, whose control designs you carry into real-time code, and work alongside the EE seats bringing up the hardware your software runs on.
Responsibilities
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
Qualifications
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
Preferred Experience
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
Reliability-aware software practice for radiation or safety-critical environments
A note on level and background: We hire this role at all levels, from Associate through Senior and Principal Software Engineer, and calibrate title, scope, and compensation to your experience. If this list doesn't perfectly match your background still reach out. We are always looking for exceptional people from many disciplines.
What this job is really like
We're a seed-stage company building toward first light on a single-route demonstrator. There's no program office and no requirements team. Your code is the first thing to run on every new board and the last thing standing between an anomaly and a lost pass, and you'll spend real time at the bench next to the hardware it drives. If you do your best work inside a large, well-resourced program, this isn't it. If you want your fingerprints on a Tbps-class link from the start, this is it.
Compensation + Benefits
In addition to base salary (to be determined on a case by case basis), compensation for this role includes:
EON believes the business should be primarily employee owned. In turn, all compensation offers include company stock options for FTEs.
Comprehensive medical, vision, and dental insurance with significant cost covered by the company for yourself and dependents.
Paid parental leave and 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).
