Ready to shape the future of data?
Matillion is the intelligent data integration platform.
We're changing how the world works with data – and we need driven, curious people who think big and move fast.
We built the Data Productivity Cloud to supercharge data productivity, and now we’re shaping the future of data engineering with Maia – our AI-powered virtual data engineers that help teams design, build, and manage data pipelines at unmatched speed.
Join #TeamGreen, where the mission comes first, collaboration drives us forward, and everyone pulls in the same direction to make a dent in the universe bigger than ourselves.
About the role
As a Principal Software Engineer on our Maia team, you'll be at the heart of everything we do: working on agentic AI systems, building new tools and integrations, and staying finger-on-the-pulse with the latest developments in Gen AI. This isn't BAU engineering—this is high-visibility, high-impact work where your decisions shape the product. You'll be driving architecture, mentoring engineers, and feeding into strategy. Things move quickly here. Requirements evolve, new opportunities emerge, and we need someone who thrives in that environment. If you're an expert Java engineer and already experimenting with Claude, Gemini, and agentic workflows—and you want to do that at scale in a world-class engineering team—this is the role for you. This role is hybrid to our Manchester office. We value collaboration and believe the best work happens when we're together—so we ask for a minimum of 2 days per week in the office. It's not just about attendance; it's about building the relationships and culture that make great engineering possible.About the role
