Senior Software Engineer, Builder Studio

We are seeking a senior full-stack software engineer to help build an innovative AI-powered platform that enables users to create custom software applications using natural language. In this role, you will own key product capabilities, from interactive builder interfaces and AI-driven code generation to secure execution environments and automated workflows. You will solve complex engineering challenges at the intersection of large language models, application development, and cloud infrastructure. Working closely with product, design, and early customers, you will turn emerging ideas into reliable, scalable experiences that make software creation accessible to non-technical users. This is an opportunity to shape a new product from the ground up within a fast-moving, AI-native environment that values technical excellence, ownership, and experimentation.

• At least five years of experience building and shipping production software, with substantial hands-on expertise across both frontend and backend development.

• Strong proficiency in TypeScript and React, including experience building complex, stateful user interfaces such as editors, visual canvases, application builders, or real-time collaborative tools.

• Solid backend engineering and API design skills, ideally with event-driven architectures or workflow systems involving retries, idempotency, and observability.

• Practical experience deploying large language model capabilities in production, including agent loops, tool calling, context management, code generation, or model evaluations.

• Strong understanding of the limitations and failure modes of AI models, with the ability to design systems that handle uncertainty and maintain reliability.

• Experience making sound security decisions for systems that execute untrusted or AI-generated code, including sandboxing, delegated authentication, scoped tokens, and secrets management.

• A proven track record of taking an ambiguous product from an early prototype to a dependable, customer-facing solution, balancing speed, scope, and quality.

• Strong product judgment and empathy for non-technical users, with a focus on making complex functionality understandable and accessible.

• Current, practical fluency with AI-assisted software development and a strong commitment to engineering quality, initiative, and end-to-end ownership.

• Preferred qualifications: Experience building low-code, no-code, AI application-builder products, or developer tools; familiarity with edge or serverless technologies such as Cloudflare Workers and Durable Objects; experience with Ruby on Rails at scale; or a background in go-to-market, sales, marketing technology, or RevOps environments.

• Familiarity with technologies used across the platform, including Node.js, Python, MongoDB, Elasticsearch, Kubernetes, Docker, Terraform, and Google Cloud Platform, is beneficial.
