Role Overview

We're looking for a Head of Social Media who lives online and knows how to make a brand feel native everywhere it shows up. You'll run Matter's day-to-day social presence: planning the calendar, publishing across platforms, jumping on trends in real time, and keeping our community engaged, leveraging creators to create content. You'll also manage a growing roster of influencers, affiliates, and UGC creators, making sure every partnership feels on-brand and performs.

This is a hands-on, in-the-weeds role for someone who's fast, plugged into culture, and as comfortable shooting a quick TikTok as they are managing a creator pipeline. You'll work closely with the founding team, who set the high-level brand direction. Your job is to bring it to life across feeds, every day.

Core Responsibilities

Owned Social Channels

• Own the day-to-day across Instagram, TikTok, YouTube, X, and Reddid; planning, scheduling, publishing, and engaging

• Maintain the content calendar and posting cadence, keeping a steady, high-quality flow across every channel.

• Oversee all UGC and influencer content, ensuring creators are posting consistently, content aligns with Matters brand standards and deliverables are executed on time.

• Adapt content to what each platform rewards, and move quickly on trends, formats, and cultural moments

• Repurpose top-performing content to secondary channels (e.g., Facebook) without losing quality

Community & Engagement

• Manage comments, DMs, and community interactions in a voice that feels unmistakably Matter

• Stay tapped into relevant conversations and communities (especially on X and Reddit) where authenticity earns trust

• Spot and surface UGC, trends, and audience insights worth acting on

Influencer, Affiliate & Creator Management

• Source, brief, and manage a roster of influencers, UGC creators, and ambassadors across Instagram, TikTok, and YouTube

• Run Matter's affiliate creator program day-to-day, helping creators build and monetize their own Matter meal plans

• Build and manage a UGC pipeline, leveraging tools like Storytime to source and coordinate creators

• Keep partnerships on-brand, on-schedule, and performing

Content & Brand Consistency

• Produce and lightly edit content yourself when needed: quick reels, photos, captions, on-the-fly posts

• Coordinate freelance editors, designers, and creators to keep output flowing

• Keep tone, visuals, and messaging consistent so social feels like one brand, not ten

Data & Reporting

• Track engagement, growth, reach, and conversion across channels and creator programs

• Use performance data to sharpen content and decide where to put effort

• Report on what's working, what's not, and what's next

What We're Looking For

• 2–4 years in social media management and/or creator marketing, ideally in consumer, food, wellness, fitness, or lifestyle brands

• Genuinely terminally online. You know what's trending before it trends and understand the native language of each platform

• Hands-on experience publishing and growing accounts across Instagram, TikTok, YouTube, X, and Reddit

• Experience managing influencers, affiliates, or UGC creators and getting consistent, on-brand output

• A self-starter who can shoot, write, and post quickly without heavy oversight

• A sharp eye for what feels on-brand and an allergy to low-quality content

• Comfortable moving fast, juggling many things at once, and building from the ground up

Why Matter

• Run the social presence of a category-defining brand and grow it from day one

• Build the creator and affiliate programs behind Matter's social engine

• Tight, direct collaboration with the founding team

• Competitive compensation + meaningful equity
