Hi there!Zapier’s Integration Platform Zone builds the connective tissue for a smarter, more powerful automation platform — one that’s ready for AI-native workflows, enterprise scale, and a new generation of integrations.
We’re hiring a backend leaning Sr. Full Stack Engineer (Backend leaning) to help us expand the Knowledge by Zapier team. Knowledge by Zapier’s mission is to empower all AI tools, internal or external, with knowledge from our 8,000+ integrations. This is done through the Link service, which syncs data from integrations, structures it to be more AI-friendly, and provides powerful retrieval capabilities. This role offers a unique opportunity to shape how Zapier understands and leverages integration data, influencing every AI product we build, and be on the leading edge of AI software products.
If you love designing intuitive systems, working across the stack (with a tilt toward backend), and enabling automation at scale, this is the team for you.
Design, scale, and maintain internal tools, APIs, and user interfaces that unlock the power of files, data, and knowledge across thousands of integrations
Work primarily in backend systems, with the ability to contribute to frontend code (React, TypeScript) as needed
Partner closely with AI and infrastructure teams to power data syncing, search, structured outputs, and test automation
Lead technical initiatives, mentor teammates, and contribute to architectural decisions that set long-term direction for the product
Help define and implement improvements to our developer-facing surfaces, including dashboards and docs
We’re looking for FullStack engineers who bring:
Strong backend experience using Python (Django preferred), Node.js, or similar frameworks
Familiarity with frontend tools like React and TypeScript, and a willingness to contribute as needed
Experience designing and consuming REST APIs, event-based systems, and scalable backend workflows
Comfort working across cloud environments, CI/CD pipelines, and observability stacks
You value collaboration, pairing, and async communication in a remote team environment
You’re customer-focused. Whether internal or external, you care about solving real problems and creating great experiences
You love learning and are curious about ambiguous or novel problems. You’re comfortable asking questions, digging in, and figuring things out
You’ve used AI tooling for work or personal use—or you are willing to dive in and learn fast. You explore new tools, workflows, and ideas to make things more efficient, and are eager to deepen your understanding of AI and use it regularly
RAG Background: Experience building or optimizing Retrieval-Augmented Generation (RAG) systems, including designing data pipelines, working with vector databases, or implementing semantic search and structured retrieval to make knowledge more accessible to AI models.
LLM experience: Experience building or supporting LLM-powered products in production
Feedback & Telemetry: Familiarity with collecting telemetry or usage metrics to inform product improvements.
Cross-Codebase Contributions: Comfort navigating and contributing across multiple services and codebases in a large, distributed system.
