Social Media & Affiliate Manager
Why SellerX
We're not just building a company; we're crafting a legacy. Your role at SellerX is pivotal because we firmly believe that our company is only as exceptional as the team we assemble. Join us in shaping the future of eCommerce and be a part of a company that values innovation, collaboration, and continuous growth.
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.
Sounds exciting but you're not sure if you tick all the boxes?
We are always happy to read your application and hear your story. Everyone's talent is unique!
