We believe all Zapiens should be rewarded competitively and equitably, using practices that are simple and transparent. This philosophy ensures we’re able to find, grow, and retain exceptional people from a broad range of backgrounds. Here’s how we define our compensation principles:

Competitive: Zapier pays well among the technology sector.
Equitable: Consistent pay practices; Pay for impact
Simple: Pay is well understood, and pay practices are built for scale.
Transparent: Zapiens know how pay works, including how their pay is determined.

A Candidate's compensation package is finalized once the interview process is concluded and accounts for demonstrated experience, job knowledge, skills, abilities, and internal equity. We use a business impact approach to base pay, which means we set pay for all Zapiens based on their demonstrated impact on Zapier’s success. In alignment with that philosophy, the upper half of a pay range is typically reserved for individuals who have consistently demonstrated a high impact in their current role and level while at Zapier.

Hi there!

Zapier is leading the way in AI automation. We’ve helped businesses increase productivity and serve their customers better through an extensive platform of integrations, robust workflow automations, and practical AI applications. Zapier’s External Platform Zone is building the infrastructure that will power the next generation of automation. At the core of this effort is Model Context Protocol (MCP) — an open standard designed to let AI agents seamlessly reason, act, and orchestrate workflows across Zapier’s 8,000+ integrations. We’re hiring a Senior Backend Engineer to help design and scale the systems that enable this vision. You’ll own APIs, build platform primitives, and work closely with cross-functional partners to define how agents access the real world through Zapier. If you’re excited about working on foundational systems, love thinking in protocols and architecture, and want to help define how AI agents get work done — this is your role.

As a Sr. Backend Engineer working on MCP, you’ll:

Design, implement, and evolve core APIs that enable agents to take meaningful actions across Zapier’s integration ecosystem
Build systems that support scalable orchestration, robust logging, and high-availability execution
Influence and collaborate on the core performance for MCP focusing on memory, context windows, token usage, and reasoning steps
Integrate with Zapier’s existing execution infrastructure and help build the interfaces between LLM clients and Zapier
Partner closely with Product, Design, Platform, and Sales teams to ensure the protocol serves both external and internal needs
Drive design decisions that prioritize scalability,...
