Social Media & Affiliate Manager

Description

About the role

We're have a vinyl accessories & matcha brand selling across Amazon and our own DTC stores, and we're looking for a Social Media & Affiliate/Influencer Manager who treats every post, partnership, and piece of creative as a hypothesis to be tested—not a box to be checked.

This is **not** a "make the feed look nice" job. We care about pretty content only insofar as it drives reach, clicks, conversions, and revenue. You'll own the full loop: build a thesis, ship it fast, read the data, kill what's losing, and pour fuel on what's working. If you get excited by a creator post that quietly 10x'd your ROAS and you immediately want to figure out *why* and replicate it, you'll fit right in.

You'll wear two hats that increasingly overlap: running our organic and paid-adjacent social presence, and building an affiliate/influencer engine that scales creator partnerships profitably across both Amazon and DTC.

What you'll own

Social media (growth-first)

- Run our social channels (TikTok, Instagram, YouTube Shorts, [others]) as a testing ground, not a brand museum—prioritizing formats and hooks that drive measurable downstream action.

- Build and maintain a content testing calendar: clear hypotheses, variants, and success metrics for hooks, formats, offers, and CTAs.

- Partner with creative to produce high-volume, performance-oriented content (UGC, short-form video, founder/POV content) rather than a handful of polished hero assets.

- Identify winning organic content and flag it for paid amplification and creator briefs.

Affiliate & influencer

- Build, run, and scale our affiliate and influencer program from sourcing through negotiation, briefing, activation, and renewal.

- Recruit creators across tiers (nano to mid-tier and up) with an emphasis on conversion efficiency, not just follower count.

- Manage affiliate platforms and links (e.g., Amazon Associates / Influencer Program, [LTK, ShareASale, Impact, Levanta, Archer, etc.]) and structure commission and incentive models that stay profitable.

- Develop creator briefs that give enough direction to stay on-brand while leaving room for the native, authentic content that actually converts.

Measurement & growth

- Define and track the metrics that matter: ROAS/MER on creator spend, CAC by channel, conversion rate, EPC, affiliate revenue, content-attributed sales on both Amazon and DTC.

- Run a structured testing cadence—document what you tested, what you learned, and what you're scaling or cutting.

- Build attribution as best you can across the Amazon/DTC split (Amazon Attribution, brand referral bonus, UTM discipline, promo/affiliate codes) and be honest about its limits.

- Report results in plain language: what moved the number, what didn't, and what's next.

What we're looking for

- A testing mindset, full stop. You think in hypotheses and experiments. You're comfortable being wrong fast and iterating, and you'd rather ship 20 scrappy tests than 1 perfect campaign.

- 3-5 years in social, influencer, affiliate, or growth marketing—ideally for a DTC and/or Amazon brand.

- Demonstrable results: you can point to programs or content you grew and the numbers behind them.

- Hands-on experience building and managing influencer/affiliate relationships at scale.

- Strong comfort with analytics—you live in dashboards, spreadsheets, and platform reporting, and you can turn data into decisions.

- Solid creative instincts paired with commercial judgment: you know a scroll-stopping hook when you see AND you ask whether it sells.

- Familiarity with the Amazon ecosystem (Brand Registry, Amazon Influencer Program, Attribution, Brand Referral Bonus) is a strong plus.

Nice to have

- Experience with paid social or working closely with a paid media team.

- Basic video editing / familiarity with content tools (CapCut, etc.).

- Experience standing up an affiliate program from scratch.

- A network of creators you can tap on day one.

How we'll know you're winning

In your first 90 days, you'll have a documented testing calendar live, a baseline set of metrics we trust, and at least a few creator partnerships and content formats proven out with real numbers behind them—so we know what to scale.
