Senior Staff Software Engineer - Front End

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 At Matillion, we are moving beyond traditional data processing to define the future of the AI Data Automation Platform. Our mission is to make data "AI-ready" at the speed of thought, centred around Maia — our autonomous AI data engineering foundation. The Senior Staff Engineer (Frontend) is a high-leverage technical leader responsible for driving architectural excellence across our React-powered ecosystem. The web UI is where Maia's power is harnessed, visualised, and controlled. This role is the technical authority responsible for ensuring our frontend is as sophisticated and performant as the AI it commands. This role partners with the Senior Staff community to lead organisational "big bets" — including the evolution of our Design System, the expansion of our micro-frontend architecture, and ensuring our platform performs at a global scale. It sits at the intersection of technical craft, product vision, and organisational influence. Matillion operates on a hybrid basis, with us coming together 2 days a week in our Manchester office to collaborate and drive our mission forward. What you will be doing • Lead the frontend architectural vision for our React-powered platform — defining scalable patterns, standards, and practices across multiple product squads • Own the Design System strategy and micro-frontend architecture, driving consistency, modularity, and long-term scalability across our product surfaces • Champion an agentic development culture — integrating AI tools into daily engineering workflows and staying ahead of the rapidly evolving GenAI landscape • Partner with Product and Engineering leadership to align frontend strategy with the Maia platform roadmap, validating architectural proposals before full-scale development • Develop engineering capability across squads through coaching, structured feedback, and leading by example on Matillion's engineering values What we are looking for • Expert-level React and TypeScript — deep understanding of component architecture, state management, event-driven architectures, test strategies, and performance optimisation at scale • Proven ability to lead the design and delivery of significant frontend projects in a SaaS product environment, including cross-team strategic efforts like Design Systems or micro-frontends • Deep proficiency in agentic development — AI tools are already part of your daily engineering workflow, not something you're exploring • Strong experience designing modular, testable frontend systems capable of supporting complex, AI-driven user workflows, with a solid grasp of frontend security best practices • A strategic, economically-minded thinker who can zoom out to the organisational level, influence decisions, and balance long-term maintainability with delivery velocity At Matillion, we are committed to providing compensation in line with market standards based on the role, job family, job level and country. This role’s estimated annual salaried pay range for this position is £76,000 - £114,000. The final salary will be based on your relevant skills, experience, and qualifications demonstrated in the hiring process.
