Senior Application Security Engineer

Are you ready to shape the future of data

Matillion is the company behind Maia, the AI Data Automation platform.

In the AI economy, demand for data is exploding. Manual data engineering can't keep up. Maia fixes that by combining 15 years of data expertise with agentic AI to eliminate the manual work that slows data teams down. Organisations like Cisco, DocuSign, and Slack are already using it to deliver real business impact, faster.

We started in Manchester and now we're global - with teams across the UK, US and India.

We are driven, curious, energetic people who move fast, think big and hold ourselves to a high standard. We're here to make a dent in the universe bigger than ourselves. And we're looking for people who want to be part of it.

Role Purpose

Matillion is built around small development teams utilising a modern, cloud-based technology stack to deliver products. The AppSec Engineer will work in an engineering capacity to product and engineering teams to ensure security is baked into the product from the design phase creating a SecDevOps workflow.
