Growth Marketing Manager

Company Overview

Function was founded with a singular focus: empower you to live 100 healthy years. We’re doing that by using the best available technology to help prevent disease and optimize health at scale. Among many accolades, Function has been recognized as one of TIME100’s Most Influential Companies of 2025.

Backed by leading investors including Andreessen Horowitz (a16z), Function serves hundreds of thousands of members and is rapidly expanding into the enterprise market. We are building the default health platform for employers—bringing preventative, data-driven healthcare to millions of lives.

We’re looking for world-class talent who believe deeply in our mission, operate with urgency, and are excited to help shape the future of healthcare.

Role

We’re seeking a highly creative, AI-first Growth Marketing Manager to drive member activation across our employer (B2B2C) channel. This is a hands-on builder role for someone who is equally strong in strategy and execution—someone who can design growth systems, run campaigns, and use AI to fundamentally rethink how activation is done.

You will operate as the “mission control” for member growth, partnering across Sales, Client Success, RevOps, PMM, Lifecycle Marketing, and Data to turn ideas into scalable, repeatable activation engines.

We’re looking for individuals who actively experiment with new tools and workflows, bringing a creative, scrappy, and execution-first approach to growth. This role is intentionally scoped as a high-potential IC with the opportunity to grow into a leadership role as the function scales. This person has a high ownership mindset with a strong bias toward action, thrives in ambiguity, and operates effectively in fast-moving environments. Above all, they are deeply motivated by Function’s mission to transform healthcare and are excited to build and scale new ways of driving impact.

Responsibilities

Own Member Activation Strategy & Execution:

• Design and execute end-to-end activation strategies that drive enrollment, engagement, and utilization across employer clients.
• Translate business goals into clear growth plans across segmentation, messaging, incentives, and channel mix.
• Balance strategy with hands-on execution—this is not a purely strategic role.

Lead With An AI-First Growth Approach

• Use AI tools to generate campaign ideas, messaging, segmentation strategies, and experimentation roadmaps.
• Build and optimize AI-powered workflows for campaign creation, testing, and iteration.
• Continuously identify ways to replace manual processes with AI-driven systems to increase speed and performance.
• Bring new, creative approaches to growth that go beyond traditional lifecycle marketing.

Build Scalable Playbooks & Systems

• Create repeatable activation playbooks that can scale across diverse employer clients.
• Develop frameworks for launches, comms calendars, segmentation, and campaign execution.
• Turn one-off success into repeatable, systemized growth motions.

Act As “Mission Control” For Activation

• Orchestrate cross-functional execution across Sales, Client Success, Marketing, PMM, RevOps, and Data.
• Ensure alignment on timelines, deliverables, and performance goals.
• Enable internal teams and client stakeholders (HR/benefits teams) with toolkits, messaging, and launch frameworks.

Measure, Experiment & Optimize

• Own activation funnel performance (signup, conversion, utilization, time-to-activation).
• Run continuous experimentation across messaging, incentives, channels, and timing.
• Partner with Data and RevOps to analyze performance and identify key growth drivers.

Qualifications / Skills

• 5–8 years of experience in growth, lifecycle marketing, or B2B2C activation (ideally in employer benefits, healthcare, or SaaS).
• Proven ability to own and execute growth initiatives end-to-end (not just support or coordinate).
• Demonstrated experience using AI tools to drive marketing workflows, ideation, and execution.
• Strong experimentation mindset with experience in funnels, cohorts, and performance optimization.
• Ability to operate in a scrappy, fast-paced environment with high ownership and limited structure.
• Experience working cross-functionally across Sales, Client Success, RevOps, Product Marketing, and Data.
• Strong communication and storytelling skills across both internal and external audiences.

Nice to Have

• Experience in employer benefits, digital health, or B2B2C subscription models.
• Familiarity with behavior change, incentives, or engagement strategies.
• Experience building enablement materials for client-facing teams.
• Exposure to high-growth or venture-backed environments.
