About the team:

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 Software Engineer at Builder.io, you will…

• Build and ship features across the Publish platform, spanning the visual editing experience, component rendering, and the integrations that make Publish work across diverse customer tech stacks, owning implementation, testing, and production verification.
• Work at the intersection of developer infrastructure and non-technical UX, contributing to the hard problem of making a component-driven, code-backed CMS feel seamless for marketers while staying reliable and composable for engineering teams.
• Partner with Product and Design to translate requirements into well-scoped solutions, surfacing edge cases early and making sensible trade-offs between speed and quality.
• Contribute to customer-facing integrations across frameworks, hosting environments, and design systems, ensuring Publish works reliably in the real-world environments our enterprise customers bring.
• Participate in the customer feedback loop, reviewing customer session recordings to understand friction, then connecting those insights directly to the features you are building.
• Write clean, performant, maintainable code, with particular attention to browser rendering, real-time preview, and component serialization challenges unique to a visual CMS.
• Collaborate actively across a global team, writing clear context, reviewing peers' code thoughtfully, and continuously raising the quality bar.

You will thrive in this role if you have…

• 3–5+ years of experience in full-stack web development with a track record of shipping features to production in a team environment.
• Strong proficiency in React and TypeScript/Node.js, with solid fundamentals in how browsers render, how components are composed, and how to write code others can build on.
• Curiosity about AI and agentic systems. 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.
• Solid API and backend foundations, including experience building or consuming REST APIs, and a genuine interest in the platform layer, not just UI.
• An eye for product quality, you notice when something feels off for the end user and advocate for getting it right, not just shipping it.
• Comfort with ambiguity, you do not need a perfectly scoped ticket to make progress; you ask good questions, make reasonable assumptions, and flag blockers early.
• Familiarity with REST APIs and modern web integration patterns, including how frontend applications communicate with backend services and third-party platforms.
• A collaborative, growth-oriented mindset, you seek feedback, learn from senior engineers around you, and take ownership of your work from first commit to production.

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!

The base salary range for this role is €90,000 - €105,000. This role is also eligible for meaningful company equity and benefits.
This position is fully remote and open to candidates in multiple locations. Compensation may vary by country and local market and will be discussed early in the interview process. Final offer amounts are determined based on experience, role-related knowledge, skills, and abilities.
