Senior Full Stack Engineer

At Complexio, we’re building the intelligence layer for enterprise AI—automatically creating a

connected understanding of an organisation’s people, processes and systems, and turning

that into real-time automation and insight. Our platform ingests structured and unstructured

data, constructs a living Event Knowledge Graph, and orchestrates multiple AI models to

uncover hidden workflow opportunities and drive autonomous action.

As a Senior Frontend Full Stack Engineer, you will join us at an exciting inflection point: you’ll

help shape the way thousands of enterprise-users engage with our platform. You’ll work with

a team of software engineers, data scientists, product experts and business analysts to craft

next-generation web applications and user experiences that bring our powerful automation

engine to life. Your role will be foundational in translating data-rich insights into intuitive,

performant, and scalable interfaces - bridging the gap between advanced AI infrastructure

and real-world business impact.

If you are passionate about working at the intersection of rich front-end engineering,

full-stack product delivery and enterprise AI innovation, and you thrive in a fast-moving,

deeply technical team, then we’d love to hear from you.
