Senior Customer Engineer

At Builder.io, we’re reimagining how teams build for the web. Our collaborative AI development platform helps product, design, engineering, and marketing teams work together with AI agents to build, review, and ship production-ready experiences on top of their existing codebases and design systems. Through Fusion and Publish, our flagship products, we help enterprise teams move faster, reduce handoffs, and deliver high-quality digital experiences at scale.

About the Role:

As a Senior Customer Engineer, you will play a critical role in guiding our enterprise customers through complex integrations and ensuring they extract the maximum value from Builder. Leveraging your deep technical expertise, you’ll lead major projects, conduct advanced workshops, and provide tailored support for our largest and most strategic customers across the EMEA region. You will be instrumental in influencing our product roadmap, fostering customer success, and positioning Builder as a key partner.

Key Responsibilities:

• Lead Enterprise Customer Implementations

Own the end-to-end technical onboarding and implementation process for strategic enterprise customers, ensuring successful deployment, platform integration, and alignment to the customer’s business goals.

• Drive Adoption and Long-Term Customer Value

Partner with customers throughout the full lifecycle, from onboarding through expansion and optimization, to drive activation, sustained usage, and measurable business impact across technical and business teams.

• Serve as a Senior Technical Advisor

Act as a trusted advisor and subject matter expert on Builder’s platform, helping customers identify high-value use cases, apply best practices, and translate product capabilities into scalable implementation patterns.

• Design and Deliver High-Impact Enablement

Lead onboarding sessions, technical workshops, advanced trainings, executive briefings, and hands-on enablement engagements for audiences ranging from senior stakeholders to developers and working teams.

• Own Advanced Troubleshooting and Technical Escalations

Serve as an escalation point for complex technical issues, partnering with customers, Support, Product, and Engineering to diagnose challenges, unblock implementations, and deliver high-quality resolutions.

• Influence Product and Technical Roadmap

Synthesize customer feedback, implementation patterns, and emerging use cases across accounts, and partner with Product and Engineering to inform roadmap priorities, product improvements, and customer experience enhancements.

• Develop Scalable Resources and Best Practices

Create and improve enablement assets, documentation, playbooks, code samples, implementation guides, and repeatable frameworks that help customers adopt Builder successfully at scale.

• Partner Cross-Functionally to Deliver Customer Outcomes

Collaborate closely with Sales, Sales Engineering, Customer Success, Product, Support, and Engineering to ensure smooth handoffs, consistent customer experiences, and strong execution against strategic customer goals.

What We’re Looking For:

• Strong Front-End Engineering Experience

6+ years of experience with HTML, CSS, JavaScript, and modern front-end frameworks such as React, Vue, Angular, or similar. You have a track record of delivering scalable, maintainable front-end solutions in production environments.

• Enterprise Implementation Experience

Experience leading technical implementations for enterprise customers, including discovery, solution design, onboarding, troubleshooting, and adoption. You are comfortable working with both hands-on engineers and executive stakeholders.

• Headless and Composable Architecture Knowledge

Deep familiarity with APIs, GraphQL, CMS integrations, design systems, component-based architectures, and enterprise-scale content workflows.

• AI and Workflow Fluency

Experience working with AI-powered development workflows, prompt-based systems, or LLM-enabled products. You can help customers move beyond experimentation and understand how AI can fit into real production workflows.

• Customer-Facing Technical Judgment

Strong ability to explain complex technical concepts clearly, guide customers through tradeoffs, and build trust with technical and non-technical audiences.

• Problem-Solving Mindset

A proactive and detail-oriented problem solver who can diagnose complex issues, identify root causes, and drive practical solutions across customer and internal teams.

• Strategic Thinking

Ability to identify patterns across customers, connect technical work to business outcomes, and turn customer needs into actionable feedback for Product, Engineering, and Go-to-Market teams.

• Adaptability and Ownership

Comfortable operating in a fast-moving environment with evolving products, priorities, and customer needs. You take ownership, communicate clearly, and continuously look for ways to improve the customer experience.

Builder.io is the collaborative AI development platform where teams and AI agents build, review, and ship together on existing apps and sites. We do it through two products — Fusion and Publish — built to replace the sequential handoffs that have always slowed teams down.

Fusion enables every role across product development to produce production-ready features from your real codebase and design system. Publish empowers marketing to launch pages and campaigns using those same components without engineering bottlenecks.
