Zapier is looking for a Senior Software Engineer, MCP (Backend) to design and scale the systems that enable AI agents to interact with Zapier’s automation ecosystem via the Model Context Protocol. You will own critical APIs, build platform primitives, and define how agents meaningfully access the real world through Zapier.

- Design, implement, and evolve core APIs that enable agents to take meaningful actions across Zapier’s ecosystem.
- Build systems that support scalable orchestration, robust logging, and high-availability execution.
- Collaborate on the architecture for MCP primitives like memory, context windows, and reasoning steps.
- Integrate with Zapier’s existing execution infrastructure and help build the interfaces between LLMs and automations.
- Partner closely with Product, Platform, and Sales teams to ensure the protocol serves both external and internal needs.
- Drive design decisions that prioritize scalability, performance, security, and clarity for developers and AI systems alike.
What We're Looking For
- 6+ years of experience designing, developing, and maintaining complex production systems.
- Comfortable writing backend services (Python or Node.js ideal).
- Experience with API design, database modeling, or CI/CD pipelines.
- Experience using AI tools to accelerate development process (e.g., GitHub Copilot, Cursor).
- Platform thinking with focus on extensibility, documentation, and robust foundations.
- Customer empathy and curiosity to meet customer needs.
- Bias toward action and ability to create structure, clarity, and momentum.
- Ownership mindset, taking initiative and being an effective communicator.
- Self-starter comfortable with ambiguity, turning loosely defined problems into concrete action.
Nice to Have
