Senior Software Engineer – Dev Tools Squad

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 turning point for how websites are built.

The old way was: choose tools, model content, write code, migrate pages, fix bugs, repeat.

The new way is: say what you want, and the system builds, fixes, and improves the site with you.

To lead this change, we are building the Autonomous Website Experience. Prismic should not feel like a tool you must learn before you can build. It should feel like a system that understands your goal and moves you forward from day one: from the first demo, to full migration, to daily updates.

Our role is to remove the heavy work behind building and running a site: shaping the structure, mapping content, wiring code, migrating pages, keeping everything correct and up to date. We turn intent into a real website that works, and keeps working.

As Prismic scales, our ambition grows: we are not just improving developer tooling — we are redefining how websites are created and maintained.

We’re looking for a Senior Software Engineer to join our Dev Tools Squad and design, build, and ship the systems that make a website drive itself.

You will work on the technical foundations of the Autonomous Website Experience: turning intent into working systems, generating sites from ideas or URLs, migrating real-world websites safely and fast, and ensuring sites remain healthy, current, and consistent over time.

This role sits at the intersection of developer experience, AI systems, modelling, and infrastructure.

Everything we build must be:

-Fast

-Correct

-Observable

-Trusted by developers and marketers

-Designed to grow in power without breaking as we expand its capabilities

-Design and build systems that transform high-level intent (a prompt, a URL, a goal) into a working, production-ready website.

-Build MCP server tools that remove boilerplate and let developers focus on building experiences, not low-level CMS-specific code.

-Create AI-powered workflows (including GitHub integrations) that suggest and implement code changes automatically, accelerating development and migrations.

-Develop safe and observable website migration systems that can map real-world sites into Prismic structures reliably.

-Evolve Prismic modelling with new field types and schema capabilities to unlock richer, more composable and future-proof website architectures.

-Reimagine how developers work with content by enabling branching and Git-like workflows for custom types and content.

-Ensure everything we ship is correct, traceable, and resilient as we expand the scope and autonomy of the system.

-Contribute to the long-term architecture that allows the Autonomous Website Experience to grow in capability without introducing instability.

-TypeScript (NodeJS)

-AWS

-SST

-Serverless architecture

-PostgreSQL

-LangGraph

-Playwright

-GitHub Actions

-React

-Cursor / Claude Code

Ideally, you:

-Build and maintain robust backend systems, and care deeply about developer experience as much as API design.

-Have worked on SDKs, frameworks, platforms, or internal developer tooling where DX is a first-class concern.

-Understand software modelling: schemas, validation, migrations, and how to evolve systems without breaking user workflows.

-Think in systems: you design solutions that remain stable and extensible as complexity grows.

-Have experience integrating AI into developer workflows, or are excited about GitHub bots, code generation, and automated code assistance.

-Care about quality engineering practices: testing, observability, traceability, and shipping code others can extend safely.

-Approach problems from the developer’s perspective: you’ve felt the pain of bad abstractions, and you design to remove friction.

-Are pragmatic: you know how to rethink fundamentals while still delivering incremental value.
