Executive Assistant and Operations Lead

Capture6 is a climate technology company focused on scaling solutions that help decarbonize the global economy and support a more sustainable, water-secure future. We’re an entrepreneurial, fast-moving team working at the intersection of technology, infrastructure, and climate impact.

The Executive Assistant and Operations Lead will provide high-impact leverage to the CEO of Capture6, while also owning key operational workflows in People/HR and general operations.

This is a remote-first role based in the Bay Area, with regular trips into our San Francisco office for key meetings, team sessions, and events, plus periodic travel for company offsites and partner engagements.

This is an ideal position for an ambitious Executive Assistant / Operations Lead who thrives under pressure, is a self-starter, and is energized by helping a mission-driven climate company scale. You are equally comfortable in the details (calendars, logistics, payroll support) and in more strategic work (prioritization, special projects, and cross-functional coordination).

You’ll be a central partner to the CEO—helping them focus on what matters most for Capture6’s mission, keeping the trains running on time, and ensuring our people operations and internal processes are smooth, compliant, and well-organized.
