Sr. Engineer, Backend (MCP) at Zapier

This role is ideal for a senior backend engineer with 6+ years of experience who is passionate about the intersection of AI and platform infrastructure. You should have a proven track record of building complex production systems and APIs, specifically using Python or Node.js. Since you'll be working on the Model Context Protocol (MCP), a background in building extensible platform products or developer tools is highly valued. This is a high-visibility position within a fully remote, "AI-first" organization. With a generous salary range reaching up to $261,200, you’ll be at the forefront of AI orchestration, helping define how agents interact with 8,000+ integrations. The role offers significant architectural influence, as you will be shaping the foundational protocol used by both internal teams and external developers. **You might be a good fit if you:** * Have extensive experience designing scalable APIs and robust backend services (Python/Node.js). * Are excited about building the "plumbing" for AI agents, including orchestration and context window management. * Possess a platform-oriented mindset, prioritizing extensibility and developer experience. * Thrive in remote-first environments and can turn ambiguous, high-level goals into concrete technical roadmaps.
