Principal Growth Marketer

Healthcare is broken at the first step: patients can't find the right care, understand what it costs, or access the medications they need. Mochi Health is fixing this.

We're building an AI-driven marketplace that makes healthcare discoverable—connecting patients to the right providers, transparent pharmacy pricing, and affordable medications. Over the past few years, we've grown rapidly by combining clinical expertise with technology that actually works for real people, not just hospital systems.

Our platform does what legacy healthcare can't: it gives patients transparent pricing before they pay, personalized medication management that follows them across providers, and long-term access to their own medical records. We're proving that healthcare can be more affordable, more human, and far more intuitive than what exists today.

Join a team that's rebuilding healthcare from the patient up. At Mochi Health, you'll work alongside people who value bold thinking, inclusive collaboration, and getting meaningful work into the world. If you want to do the most impactful work of your career, this is where to do it.

The Role

As Principal Growth Marketer at Mochi Health, you'll own patient acquisition, activation, and retention across our entire platform. You'll build and lead the growth function—spanning performance marketing, lifecycle marketing, growth product, analytics, and conversion optimization—to scale our patient base while maintaining efficient unit economics in a competitive, regulated market.

This role is equal parts strategist, builder, and operator. You'll develop the growth playbook that brings us to millions of patients, build the infrastructure to execute it, and drive the day-to-day execution that hits aggressive growth targets. You'll work at the intersection of healthcare, consumer marketing, and marketplace dynamics—balancing patient trust, clinical quality, and business growth.

A Note on This Role: ~80% IC, ~20% Management

This is fundamentally an individual-contributor role, not a management-heavy position. The majority of your time will be spent directly in the work: designing experiments, digging into data, writing strategy, optimizing campaigns, and solving growth problems hands-on. You'll lead a small, high-leverage team of 5-7 people—enough to execute against the strategy, without pulling you away from the work itself.

If you're looking for a role where you mostly delegate and review, this isn't it. We need someone who wants to stay close to the data, the campaigns, and the experiments—someone energized by doing the work, not just directing it.

This is a high-impact role for someone who has scaled consumer health or marketplace businesses, thrives on data and experimentation, and understands that in healthcare, growth must be built on trust and clinical outcomes, not just performance marketing tactics.
