Office Administrator

Ulysses is the ocean company. We design, manufacture, and operate autonomous vehicles for surface and subsea operations — taking on the most critical tasks across defense, commercial, and scientific missions. Our vertically integrated platform includes Mako, a modular AUV with 72-hour endurance and more onboard compute than any vehicle in its class; Leviathan, an autonomous surface vessel mothership; and Kraken, our automated launch-and-recovery system that closes the loop between surface and subsea with zero human intervention.The ocean covers 71% of the Earth's surface and drives a $2.6 trillion global economy, yet it remains the least monitored domain on the planet. We're changing that — building autonomous systems that collapse the cost of ocean operations by orders of magnitude so that persistent coverage becomes the baseline, not the exception. We operate globally today across defense, ocean science, and commercial survey, working with partners including the U.S. Navy, the Government of Australia, the Great Barrier Reef Foundation, and The Nature Conservancy.Founded in 2023 and headquartered in San Francisco, Ulysses has raised $48 million in funding from Andreessen Horowitz, Booz Allen Ventures, Harpoon Ventures, Pebblebed, Lowercarbon Capital, and others. Our team is lean, hands-on, and fast — we prototype in the shop, test on the water, and ship. If you want to work at the frontier, there's no frontier bigger than the ocean.ABOUT THE ROLEWe're hiring an Office Administrator to own our front desk and be the first face people see at Ulysses.
