Senior Software Engineer – Editor Agent Squad

Job description

Work from anywhere in Europe! Hello. We're Prismic. At Prismic, we believe the future is all about autonomous websites & hyper-personalised user journeys. Our mission is clear: enable marketers & engineers to shape highly empathic web journeys at scale. We are at a pivotal moment for Prismic. The rise of agentic AI systems is transforming how content is created, edited, and scaled. What used to be a sequence of manual actions is becoming a set of interactions with agents that understand intent and produce concrete results. To lead this shift, we are building agents that will become primary interfaces to the product. The Editor Agent is central to this strategy. The Editor Agent operates within the same editing surface as our users.

You will design and build the systems that allow the Editor Agent to: -Interpret intent -Plan editing actions -Execute changes safely within the editing surface -Remain observable, testable, and evolvable over time The Editor Agent must expose a clear interface for both human and programmatic callers, and it must grow in capability without becoming fragile as we expand what it can do. What you will be doing 🔧 -Design and implement the core architecture of the Editor Agent, enabling it to transform instructions into reliable editing operations. -Build agentic workflows that orchestrate LLMs, tools, and internal APIs to create or modify pages within the editor. -Engineer systems that allow the agent to assemble rich page structures: forms, CTAs, testimonials, logos, generated images, and other reusable components. -Develop clear and stable interfaces so…
