Note: The job is a remote job and is open to candidates in USA. Builder.io is the collaborative AI development platform where teams and AI agents build, review, and ship together on existing apps and sites. As a Senior Software Engineer, you will design and build the APIs and SDKs that power Publish, contributing to the future of AI-driven content workflows and ensuring seamless integration into diverse customer tech stacks.

Responsibilities

• 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

Skills

• 6+ years of experience in full-stack web development with a proven track record of shipping complex, production-grade features independently
• Deep expertise in React and TypeScript/Node.js, with strong instincts for performance, architectural patterns, and the rendering challenges specific to visual editors and component-driven systems
• Strong API and backend fluency, including experience designing and building scalable REST or GraphQL APIs, and a genuine interest in the platform and infrastructure layer, not just the UI
• 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
• 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

Benefits

• Unlimited time off. 3 weeks is the minimum that we will ask you to take each year
• Mental health days. We encourage you to take at least one per quarter to recharge
• Paid parental leave. 12 weeks of full pay for the birth and care of a newborn child, or for the placement of a child for adoption or foster care
• $500 home office improvement budget. Help get what you need to be comfortable working in a digital-first environment
• $500 annual learning & development budget. Feel supported and empowered to continue developing your skills
• Co-working space reimbursement. Work from any WeWork at anytime with an All Access pass, or reimburse up to $300/month at another local co-working space
• Health Insurance. 100% employer-paid premiums for medical, dental, and vision insurance for employees, and 50% covered for eligible dependents
• Additional Insurance. Depending on location, Builder covers your life insurance, short- and long-term disability, and you'll have access to supplemental benefits like accident and critical illness insurance
• 401k (for US based team members). Contribute to your financial future
• Real equity. We have a four year vesting schedule with a one year cliff. We also have a ten (10!!) year exercise window 🤯  (yeah, we're pretty stoked about it!)
