Key job responsibilities
Design develop and optimize highly reliable flight software for optical inter-satellite link systems spanning low-level device drivers and real-time control loops to high-level autonomous behaviors fault management and AI/ML-driven decision-making that target embedded linux and RTOS (Real Time Operating System)

Architect and implement fault-tolerant redundant software systems that keep optical links alive across a constellation of satellites including health monitoring and autonomous recovery without ground intervention

Build and maintain robust test validation and simulation infrastructure from hardware-in-the-loop testbeds and software-in-the-loop virtualizations to automated regression suites

Own the full lifecycle of embedded software delivery - from requirements decomposition and architecture design through implementation code review integration deployment and long-term maintenance of software running on satellites in orbit

Collaborate deeply with cross-functional teams spanning hardware optics systems communications and operations engineers to design integrate test and deploy high-speed optical communication systems that push the boundaries of space-based networking

Drive continuous improvement of deployment and over-the-air (OTA) update processes ensuring new capabilities and fixes can be safely and reliably delivered to hundreds of satellites on orbit with minimal operational risk

Partner with software and hardware teams to lead board bring-up and integration efforts including developing and debugging low-level BSP (Board Support Package) components validating peripheral connectivity (Ethernet PCIe SPI I2C flash devices) and ensuring seamless hardware-software integration from prototype through production





A day in the life
As a Software Engineer on the Optical Inter-Satellite Link team you wont just write code - youll see it fly. Your software will control and monitor high-speed laser communications between satellites moving at orbital velocities and youll be there for every stage of the journey: from early design and on-the-ground verifications to watching your code commission an optical link for the first time in orbit.

About the team
You will join a multi-disciplinary team of top-notch engineers whose work spans an unusually wide aperture: embedded flight software running on satellites in orbit cloud-based systems powering mission and network operations automation frameworks that keep a growing constellation healthy and AI-driven capabilities that make our optical links smarter with every orbit. We collaborate closely with optical electrical firmware opto-mechanical and operations teams and with partner organizations including Mission Operations and Optical Network Operations to deliver one of the most advanced optical communication systems ever built.
