What are the responsibilities and job description for the Social Media & Affiliate Manager position at SellerX?
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.
The role is fully remote and based in the USA.
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.
