Marketing Analytics Lead

At ZBiotics, we make genetically engineered probiotics that improve daily life. As a group of motivated, yet down-to-earth people, we are fueled by two things: a love for science and a commitment to being people-first. GMO products like ours – built to create benefits for people in their daily lives – are the future. As the first to market, we believe it’s our duty to set a high bar for product quality, safety, and transparency for others to follow.

In 2019, ZBiotics launched Pre-Alcohol™ – the world's first genetically engineered probiotic drink – designed to break down acetaldehyde, an unwanted alcohol byproduct. In 2024, we launched Sugar-to-Fiber™ – a genetically engineered probiotic drink mix – that creates fiber from the sugar you already eat, contributing to microbiome health. With a full line of genetically engineered probiotics in development, our team is growing.

We’re looking for people as excited as we are to build this new category of consumer products. ZBiotics is headquartered in San Francisco and backed by venture investors including Y Combinator and Khosla Ventures, among others.

We're looking for a Marketing Analytics Lead who is equally at home writing a SQL query and designing a survey, who can build a dashboard and explain what it means to a non-technical stakeholder, and who brings enough statistical rigor that A/B testing is second nature. This person will be embedded in the Marketing team—working directly with the CMO, VP of Growth, and Brand Director—while partnering closely with our central Data & Analytics team on infrastructure and standards.

As Marketing Analytics Lead, you are the analytical engine behind ZBiotics' growth marketing function. You ensure that the team's performance data is accurate, accessible, and actionable—and that our decisions are grounded in rigorous analysis, not instinct alone.

You own the data infrastructure that powers marketing reporting, the measurement frameworks that connect spend to outcomes, and the analytical partnership that keeps Marketing leadership operating with a clear view of where we are and where we're headed.

This is not a reporting-only role. You'll shape how we think about attribution, incrementality, and brand impact—areas where the right frameworks matter as much as the right data.

You will report to the Chief Marketing Officer, with a dotted line to the VP of Growth Marketing, who will be a primary internal client. You will also partner regularly with the Brand team on awareness campaigns and qualitative insights work, and with our central Data & Analytics team, keeping them informed on marketing data infrastructure decisions and aligned on shared standards.

The following are essential functions to this role:

• Own marketing analytics across DTC and Amazon, including paid acquisition, retention, LTV, and channel-level performance.
• Build and maintain attribution models for DTC acquisition that account for multi-touch and organic effects—not just last-click.
• Analyze Amazon performance data including traffic, conversion, ad spend efficiency, and organic/paid contribution.
• Identify performance trends and surface actionable insights to growth leads on a regular cadence.
• Support the Growth Marketing and Ecommerce teams on the design and analysis of A/B and multivariate tests across paid channels, email, website, and Amazon storefronts.
• Set standards for test design, sample sizing, and statistical significance across the marketing team.
• Be the resident expert on when a test result is meaningful and when it isn't—and communicate that clearly.

• Support the ecommerce team on updating Marketing on website and digital…
