Overview

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, and we aim to create an entirely new industry capable of removing tens of billions of tons of CO2 within the next decade. We are building the operating system to plan, orchestrate, track, and optimize enhanced rock weathering. You will combine deep full-stack technical skills with empathy and design thinking to build and scale our interconnected platform.

Some examples of the diverse challenges you might work on include:

  • Interactive geospatial tools for mapping, analysis, and optimization
  • Creative automated and human-in-the-loop workflows for digitizing PDF maps and records
  • Pipelines for ingesting, converting, and analyzing raw data logs from agricultural machinery
  • Audit-ready representation, tracking and reconciliation of an array of real-world activities
  • Laboratory information management systems (LIMS) for tens of thousands of field samples

About Lithos

Lithos Carbon revolutionizes the carbon capture industry through enhanced rock weathering technology. We work with farmers to spread basalt rock on farmland, which increases soil health and repurposes post-industrial waste. Our technology targets removing carbon dioxide from the atmosphere at a fraction of the cost of other methods, while helping farmers improve crop yields. Our team includes leading academic scientists and proven entrepreneurs, and we are backed by top-tier investors. We began commercialization in 2022 and have signed customers for permanent carbon removal credits, including Stripe, Alphabet, Shopify, and McKinsey's Frontier program.

Requirements

You might thrive in this role if:

  • You have experience building apps for non-technical power users in a fast-paced, early-stage environment. We're flexible on background, but candidates without mid-senior engineering experience are not likely to be a fit
  • You are fluent in modern web development across the full stack and have experience with technologies similar to our current stack (React, TypeScript, Phoenix and LiveView, and Postgres/PostGIS/SQL). You should be able to rapidly pick up a new language or technology from first principles
  • You have excellent communication skills and are comfortable operating in a highly ambiguous environment. You can work independently and collaborate with internal and external stakeholders to achieve business goals
  • You balance scrappy, resourceful solutions with recognition of key areas for longer-term investment and understand when to take on tech debt vs. paying it down

Benefits

  • Competitive salary (the posted salary range for this role is $140,000 USD - $180,000 USD, depending on experience) and meaningful equity compensation
  • Comprehensive health coverage including medical, dental, and vision
  • Access to our 401k plan
  • Unlimited PTO and sick days
