Senior Software Engineer

About the team:

Builder.io’s Fusion engineering team is a fast-growing team focused on developing the Fusion project, an AI Software Engineer that enables Product Managers, Designers and Engineers within an organization to contribute seamlessly to your company's codebase and product. This global team is responsible for innovating ways to accelerate the development of interactive experiences and product features, making product development accessible across the organization.

As a Senior Software Engineer, you will...

• Partner heavily with Product Managers and Design to not just build, but help shape and define world-class product experiences based on technical feasibility and user impact.
• Own the full feature cycle, from joining customer calls to identify friction points, to architecting the solution, implementation, testing, and verifying success in production.
• Engineer the bridge between intent and execution: You will build the product that translates a Designer’s vision or a PM’s requirement into real production code within a customer’s codebase. You are solving the hard problem of making an inherently rigid, developer-centric world (Git, CI/CD, code structures) accessible to non-technical users.
• Act as a technical bridge between the code and the customer. You will translate complex customer requirements into scalable technical solutions and shorten the feedback loop between user pain and feature release.
• Lead technical decision-making for your features, prioritizing speed-to-value without sacrificing code quality or long-term maintainability.
• Navigate the complexity of "Code-as-Data": You will connect the dots between our platform and the customer's diverse technical environments. You aren't just shipping features; you are building a system that must intelligently navigate, understand, and modify external codebases reliably.

You will thrive in this role if you have…

• 6+ years of experience in full-stack web development with a proven track record of shipping complex products to production.
• Deep expertise in React (or other modern frontend development framework) and Node.js/TypeScript, with an eye for performance and architectural patterns.
• Strong Product Intuition: You care about why you are building something as much as how. You are comfortable making product micro-decisions and dealing with ambiguity.
• A Customer-First Mindset: You are comfortable speaking directly with customers, asking the right questions to uncover the root problem, and owning the resolution.
• Cloud Fluency: Experience architecting scalable systems on AWS or Google Cloud.
• High Agency: You don't 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!
