About The Position

As a Senior Software Engineer at Lithos, you’ll work directly with our Head of Engineering to build the operating system for one of the largest carbon dioxide removal efforts in history. Carbon removal is a mass transfer problem. We need to create an entirely new industry capable of removing tens of billions of tons of CO2 — the same order of magnitude as humanity’s entire global production of food, or concrete, and to do all this within the next decade. Our bet: the best chance of success is by leveraging three industries already capable of this scale: agriculture, mining, and transportation. But just having the physical and human infrastructure is not enough. At Lithos, we’re building the operating system to plan, orchestrate, track, and optimize enhanced rock weathering. You'll combine deep full-stack technical skills with empathy and design thinking to build and scale our interconnected platform.

Requirements
