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.\nWho are we?\nElsight 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. With 10x year-over-year revenue growth and rapid global expansion, we're scaling fast-and we're just getting started.
