Job description

E-Commerce Manager — Marketplace & Social Commerce (Amazon, Walmart, Shopify, Whatnot, TikTok Shop)

**Location:** New York, NY

**Reports to:** CEO

**Type:** Full-time

---

Now we're building a direct-to-consumer and marketplace business to grow our brands, reach shoppers directly, and create a more diversified, resilient sales mix. This is a ground-floor opportunity to shape that effort.

The Role

We're hiring our first **E-Commerce Manager** to own and grow the company's presence across **Amazon, Whatnot, and TikTok Shop**.

This is a builder's role. You'll start as a hands-on operator — writing listings, running ad campaigns, hosting live shows, and analyzing performance yourself. As the channels prove out, you'll grow into the leader of the function: managing third-party agencies, hiring and directing internal team members, and setting strategy across all three platforms.

The ideal person is equally comfortable in the weeds (optimizing a product detail page or going live on camera) and at the whiteboard (building the channel roadmap and P&L). You're scrappy, data-driven, and excited to build something from zero.

What You'll Own

Amazon (Seller Central)

• Own the full Seller Central operation: catalog and listing quality, content and A+, pricing, Buy Box, and Brand Registry.
• Build and optimize the SKU catalog, including bringing our broad off-price assortment online (a backlog of ~180+ SKUs to build and list).
• Manage advertising (Sponsored Products/Brands/Display) — either directly or through an agency — against clear ROAS/ACoS targets.
• Coordinate inventory, FBA/FBM strategy, replenishment, and account health with our operations and supply chain teams.

Whatnot

• Launch and grow the company's live-selling presence, leveraging our depth of branded and value inventory — a natural fit for live-auction and closeout formats.
• Plan, host, and produce recurring live shows; build a repeat audience and community.
• Own show merchandising, pricing/auction strategy, fulfillment coordination, and post-show analytics.

TikTok Shop

• Build the TikTok Shop channel across our consumer brands (starting with XO Poppy), including catalog, live shopping, and the affiliate/creator program.
• Recruit and manage creator and affiliate partnerships; brief content, negotiate commissions, and track performance.
• Drive short-form content strategy and live shopping events, in partnership with agencies and creators.

Agency & Team Management

• Select, onboard, and manage third-party agencies (ads, content, creator sourcing, listing services); hold them accountable to scope, budget, and results.
• As channels scale, define roles, hire, and build out an internal e-commerce team — and lead them as a player-coach.
• Own the channel calendar, promotional planning, and cross-functional coordination with operations, brand, compliance, and finance.
• Build the growth roadmap and set targets across all three channels.
• Own channel-level reporting and unit economics; make data-driven decisions on assortment, pricing, and spend.
• Track profitability by channel and SKU, factoring in fees, ad spend, returns, and fulfillment costs.

What We're Looking For

Required

• 3–6+ years running e-commerce/marketplace channels, with hands‑on ownership of at least one of Amazon Seller Central, TikTok Shop, or Whatnot (Amazon strongly preferred).
• Demonstrated results growing revenue and margin on marketplace or social‑commerce platforms.
• Strong analytical skills — comfortable in spreadsheets, reading channel dashboards, and managing to KPIs (ROAS/ACoS, conversion, sell‑through, contribution margin).
• Experience managing agencies or external vendors and holding them to results.
• A builder's mindset: self‑directed, resourceful, and comfortable being the whole team before you have one.

Preferred / Nice to Have

• Experience with live commerce (Whatnot, TikTok Live, Amazon Live) — including hosting on camera.
• Background in consumer electronics, accessories, or fast-moving consumer goods.
• Familiarity with the off‑price/closeout model and moving diverse, value‑driven assortments.
• Creator/influencer marketing and affiliate program experience.
• Working knowledge of listing tools, feed management, and marketplace analytics platforms.

Why This Role

• **Build from zero.** You'll define the channels, the playbook, and eventually the team.
• **Real inventory, real brands.** Established portfolio and supply behind you — not a startup guessing at product‑market fit.
• **Room to grow.** This role is designed to scale from individual contributor into a department leader.
