Engineering Senior Recruiter

Rainmaker is pioneering a modern cloud seeding system to mitigate water scarcity and inclement weather. Rainmaker is a high-performance research, engineering, and operations company. Our work requires scientific rigor, technical excellence, disciplined execution, and strong cross-functional communication across the cross-functional teams.

We are hiring a Senior Recruiter to help build Rainmaker's recruiting engine: the system that hires exceptional technical, scientific, and operational talent with an extraordinary bar of excellence.

You will own recruiting end to end: how we source, how we run interviews, how we make decisions, and how candidates experience Rainmaker from first contact to signed offer. You will partner closely with the Head of People, leadership, and hiring managers, but recruiting execution is yours.

Build the recruiting engine

You will build the system that enables Rainmaker to hire exceptional people consistently, from sourcing and structured interview loops to closing playbooks and the weekly operating review that keeps every search tied to company priorities. The goal is to make hiring fast, predictable, and disciplined as the company grows, so that quality is the reliable output of a system rather than the product of heroics.

You will own sourcing strategy and proactive pipeline-building for every critical role, because the people who meet Rainmaker's standard aren't always the ones applying. Reaching them takes structured target mapping, sharp outreach, and the judgment to tell who is genuinely exceptional.

Run a rigorous, evidence-based hiring process

Even the people we choose not to hire should leave with respect for the company and the seriousness of its work.

Protect Rainmaker's bar and culture

You will be the steward of hiring quality across every search, defining what great looks like for each role and holding that line against pressure for speed, convenience, or headcount. Hiring is where Rainmaker's culture is reinforced or eroded, and your most important job is to grow the company without ever lowering the standard that makes it exceptional.
