# Networking Senior Software Engineer

Description Description We're looking for a Networking Senior Software Engineer to join our Networking team and build the heart of Halo: Reliable connectivity, multi-link bonding data plane that fuses cellular, satellite, and RF links into one resilient connection. You'll work across the Halo device and the cloud Halo server, on the same data-plane code that runs on both ends of the tunnel: custom UDP transport, packet sequencing, deduplication and reordering, adaptive per-link scheduling, tunneling, and VPN routing. This is deep, hands-on networking and systems work in Python and C/C++/Cython, on the technology that is quite literally Elsight's product. If you love making unreliable links behave like one solid pipe, you'll have a lot of fun here. Who are we? Elsight builds the technology that keeps autonomous systems connected and mission-ready-anywhere, across air, land, and maritime domains. Our Halo platform is already field-proven across more than 500,000 operational hours and trusted by 80+ customers worldwide, from defense forces to commercial operators. We took a bold idea and turned it into a proven public company (ASX: ELS) at the forefront of the autonomy revolution. Wit
