Senior Associate, Full-Funnel Growth Creative

Mammoth Brands • New York, NY

5d • $71,200 - $89,000 • Hybrid

About The Position

Mammoth Brands (formerly Harry’s Inc.) is the modern CPG company behind brands Harry’s, Flamingo, Lume, Mando, and Coterie. We’re building a new model—and home—brands, founders, and talent looking to solve unmet needs, improve peoples’ lives, and ultimately challenge the status quo. Our mission is to “Create Things People Like More.” Simply put: everything we do should be better than what already exists. If it’s not, we don’t do it. This guides everything we do, from developing the best product experiences, to making Mammoth Brands a great place to work, to exploring innovative ways to give back to our community.
We got our start in 2013 when our co-founders created Harry's. They built the brand differently—online first, prioritizing direct relationships with customers—and in the process learned they’d created something bigger: a playbook and platform that could help other brands grow and scale to their full potential, and a vision to reimagine consumer packaged goods. Today, Mammoth Brands is a growing portfolio of brands and the largest CPG company built in the last 20 years. Even as we grow, we take extra care to maintain the small, scrappy, entrepreneurial culture that helped to get us where we are today: to create a company that people like more, that better serves its customers, employees, and community. As a company, we’re also committed to making a positive impact and have donated over $20 million through our network of nonprofit partners to date.
We build brands that move fast and think big — and we hire people who are curious about AI, willing to experiment with it in their day-to-day work, and excited to accelerate what's possible. We prioritize giving our team the tools, training, and space to build real fluency, so you grow alongside the technology and help shape how we use it.

Most performance creative roles live in one lane: you're either the strategist with the deck, the maker with the camera, or the media buyer with the dashboard. This role owns all three.
As Senior Associate, Full-Funnel Growth Creative, you'll run the complete loop — from pulling insights and writing the brief, to shooting and editing the asset, to trafficking it into paid channels and reading the results. You'll do this across three brands (Harry's, Flamingo and Lume), contributing towards our high-velocity creative engine that turns consumer understanding into measurable growth for new products.
You'll sit within the Upstream team and report to the Director of Upstream Innovation, Brand Marketing, working closely with Growth, Makers, and Supply Chain. This is a rare opportunity to drive creative output and media performance simultaneously — with real accountability, real visibility, and real impact.

Requirements

• You're a full-stack growth creative — someone who gets energized by owning the whole thing, not just one piece of it. You probably have a background in performance marketing, content creation, or growth, and at some point realized the lane was too narrow. You're equally comfortable in a spreadsheet and behind & in-front of a camera when necessary.
• Customer-obsessed: you instinctively ask what the customer needs to hear, not just what the brand wants to say.
• Data-fluent: you can pull and interpret performance data independently, and you use it to make better creative decisions — not just to report on the past.
• A maker: you're hands-on by default. Shooting, editing, and designing are things you actually do, not things you delegate.
• AI-believer and adoptor: you see AI tools as a creative accelerator and are actively building fluency in the latest generation of generative video, image, and copy tools because you truly believe it’s not only the future, but the present
• Socially native: you understand the nuance of how audiences consume content differently on TikTok vs. Meta vs. YouTube, and you design briefs for those differences instinctively.
• Fast and iterative: high-output environments energize you. You can move quickly without losing craft or curiosity.
• A clear communicator: you can tailor a message — written or verbal — to any room, from a creative review to a leadership readout.
• Proactive: you're comfortable with ambiguity and will create structure where there isn't any rather than waiting for it.
• 2–4 years of experience in performance marketing, growth creative, or a related role — ideally at a DTC brand, agency, or startup where you touched creative and media together.
• Hands-on experience with paid social platforms — Meta Ads Manager and/or TikTok Ads Manager — including campaign setup, daily optimization, and reporting.
• Proficiency in creative production tools: Adobe Premiere, Photoshop, Illustrator, After Effects, and/or Figma.
• Comfort with Excel or Google Sheets for data manipulation, performance analysis, and test tracking.
• Experience briefing and producing UGC or creator-led content.

Nice To Haves

• Bonus: experience managing media across Google, Snap, or YouTube in addition to Meta and TikTok.
• Bonus: experience working across multiple brands simultaneously.

Responsibilities

• Mine performance data, consumer insights, and platform trends to identify what's working, what's stale, and what's worth testing next.
• Develop testable creative hypotheses — framing the 'why' behind each concept before production begins.
• Write clear, actionable creative briefs (for yourself and external collaborators) that translate consumer truth into executional direction.
• Conduct ongoing competitive analysis across Harry's, Flamingo, and Lume category landscapes to surface opportunities and whitespace.
• Ideate, concept, and script, 5+ net-new creative concepts per week, per product for paid social. Strong candidates will also be able to shoot and edit when appropriate.
• Produce assets across formats: short-form video, static, UGC-style, and light motion — comfortable owning end-to-end with minimal handoffs.
• Use AI tools (e.g. Veo, Imagen, ChatGPT) to generate, iterate, and accelerate asset production.
• Support content capture on set — from scrappy phone shoots to larger-scale productions.
• Traffic and launch campaigns across paid social channels (Meta, TikTok, Snap, YouTube, and others), independently managing day-to-day ad operations.
• Monitor key performance metrics daily, flag meaningful trends, and make real-time optimizations to maximize efficiency of spend.
• Build and maintain a structured testing and learning plan — clear hypotheses, defined success metrics, and stakeholder-ready readouts.
• Translate performance results into the next iteration of creative, closing the loop between what ran and what gets made next.
• Report on learnings to cross-functional stakeholders, clearly communicating what worked, what didn't, and what we do next.
