Job description

Overview

We’re looking to hire our first ML/AI engineer to help shape and lay the foundations of ML/AI at CUR8. From a team perspective, you will work closely with our science and engineering teams to help predict delivery risk of carbon removal credits, and surface these to our B2B customers.

Responsibilities

• Working with our science team to build new risk models, and improve existing ones. As well as identifying new sources for data that feeds these models.
• Working with the engineering team to surface the outputs of these models via APIs.
• Product-wise, you will work on solving multiple product problems and big challenges with the team, including:

Benefits

About CUR8

The science is clear - even if we do everything else right on reducing emissions, the world needs to remove 5-10 Gigatonnes of CO₂ by 2050. There is no Net Zero without carbon removals.

At CUR8, we're driven by building the worldwide market for carbon removals. We're on a mission to facilitate 1Bn tonnes of carbon removed in a single year. Today, we're doing that through our leading science, procurement, and management platform. Empowering companies and financial institutions across the world with insights, carbon credit portfolios, and software tooling to neutralise their emissions.

Today, for companies around the world, we are their Copilot for Carbon Removal.

Process

Our process aims to give all of us the chance to get to know each other, our aspirations, and whether this is an exciting fit. It starts with an initial chat to tell you more about CUR8, what we're looking for, and understand more about your goals. Next is a skills-focused interview, which leads to an ideally in-person final stage split over two parts: a working session with team and a 1:1 founder meeting.

Every deal you deliver helps remove carbon from the atmosphere—and our work really matters, every single day. If you're passionate about reversing climate change, love collaborating with true experts, and want to have real impact—apply now! If you're not a perfect match but will make CUR8 stronger, we want to hear from you.
