At Scrub AI, we’re using AI and machine learning to solve a problem that has frustrated businesses for years: extracting messy data from spreadsheets.

Dealing with inconsistent, unstructured data is a tedious but essential task. We’re building technology that automates the process of extraction, transformation and validation with superhuman accuracy. By applying the latest advances in machine learning, we make data scrubbing seamless. We are initially targeting the insurance industry and have secured contracts with some of the largest companies in the space. Looking forward, our technology has the potential to transform sectors ranging from finance to healthcare.

We recently secured another £1M in funding (we’ve raised over £2.7M total) and are scaling up. We’re looking for a Senior Full Stack Engineer to help us build and scale our AI-powered data platform. This is an opportunity to work at the intersection of machine learning, automation, and web development, solving high-impact challenges in a fast-moving startup. If you enjoy working with cutting-edge technology and real-world data problems, we’d love to hear from you.
