You are excited about building products where AI plays an active role in content workflows, and you want to help shape what that looks like in practice. * Strong product intuition. You care as much about why you are building something as how, and you are comfortable making product micro-decisions and navigating ambiguity without waiting for perfect requirements. * A customer-first mindset. You are comfortable speaking directly with enterprise customers, asking the right questions to uncover root problems, and owning the resolution end-to-end. * Cloud fluency. Experience architecting scalable systems on AWS or Google Cloud. * High agency. You do not wait for a ticket to be perfectly defined; you seek out the problem, define the solution, and deliver value iteratively. The items above are a starting point for a conversation, not a hard list of requirements. If this role excites you, we hope you will apply! ## Description Builder.io's Publish engineering team builds the platform that empowers marketing and content teams to launch pages and campaigns using production-grade components, without engineering bottlenecks. This is a full-stack platform engineering team. You will work across the APIs, SDKs, and plugins that power Publish, as well as the visual layer that sits on top of it. The platform must integrate reliably into diverse customer codebases and tech stacks, making backend fluency and API design just as important as frontend craft. We are moving fast toward agentic Publish workflows, where AI can autonomously create, manage, and ship content experiences, and this team will be at the center of building that future. If you are excited about building scalable platform infrastructure that sits at the intersection of developer tooling, content management, and AI-driven automation, this is the team for you. As a Senior Software Engineer at Builder.io, you will… * Design and build the APIs, and SDKs that power Publish, ensuring they are scalable, well-documented, and reliable for the engineering teams that integrate them into their own codebases. * Contribute to the agentic future of Publish, building the backend infrastructure and APIs that will power AI-driven content creation, management, and publishing workflows. * Act as a technical bridge between the platform and the customer, translating complex enterprise requirements into scalable solutions and shortening the feedback loop between user pain and feature release. * Navigate the complexity of a visual CMS at scale. You are not just shipping features; you are building a platform that must render reliably and integrate seamlessly across wildly diverse customer tech stacks, hosting environments, and design systems. * Shape the technical direction of the Publish platform, leading through code reviews, pair programming, and taking proactive ownership of technical debt and quality issues. You will help raise the technical bar through design docs, architectural decisions, and giving substantive feedback on others' designs. * Drive drama-free launches, anticipating edge cases, surfacing risks early, scoping projects to the right balance of effort and value, and delivering work that stands up to scrutiny. ## Related Videos - [WeAreDevelopers LIVE – AI, Freelancing, Keeping Up with Tech and More](https://www.wearedevelopers.com/videos/1786-wearedevelopers-live-ai-freelancing-keeping-up-with-tech-and-more) - [Putting the Graph In GraphQL With The Neo4j GraphQL Library](https://www.wearedevelopers.com/videos/257-putting-the-graph-in-graphql-with-the-neo4j-graphql-library) - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [Stop using Node.js like in 2020!
