Manager, Retail Media & Shopper Marketing

eJam•Santa Ana, CA

About The Position

eJam is a bootstrapped consumer products company that has built, scaled, and exited multiple brands — all without ever taking a dollar of outside capital. Our portfolio includes category leaders ranked at the top of Amazon, carried in major retailers nationwide, and sold across DTC, marketplaces, and every channel in between. We’re not a startup hoping something works. We’re a team that has done it repeatedly — taken products from zero to eight figures, landed them on retail shelves nationwide, and built real brands that consumers love. We operate like a holding company with the speed of a startup: small team, no bureaucracy, massive ownership. This is the place where you’ll see the entire machine — sourcing, product development, packaging, manufacturing, compliance, marketing, marketplace strategy, retail — all under one roof. If you want to learn how consumer products actually get built and shipped at scale, there is no faster education than this. This is a delivery role. You are not here to build strategies that sit in a deck or manage processes that produce reports. You are here to produce results—measurable, visible, tied to the P&L. Every platform you manage, every campaign you launch, every dollar you allocate will be evaluated on what it actually delivered: incremental revenue, new customer acquisition, contribution margin improvement, market share gains. You will set targets with the CMO, commit to them, and be held accountable for hitting them. If something isn’t working, you are expected to identify it, fix it, and communicate it—not wait for someone to notice.

Responsibilities

Amazon Advertising. Full-funnel strategy and hands-on execution across Sponsored Ads (SP, SB, SD), Amazon DSP (display, video, OTT/CTV, Streaming TV, Prime Video Ads), and Amazon Marketing Cloud (AMC). You build campaigns, write AMC queries, configure audience segments, optimize bids, and analyze performance at the ASIN level. You own the relationship between advertising spend and business outcomes—TACoS, organic rank, Subscribe & Save enrollment, NTB acquisition, branded search lift—not just ROAS.
Retail Media Networks. Strategy, execution, and budget management across Walmart Connect, Target Roundel, Instacart Ads, DoorDash Ads, ibotta, and Criteo Retail Media. Each platform has different ad formats, bidding mechanics, measurement models, and audience data. You understand the differences and allocate budget accordingly. You evaluate emerging platforms and new ad formats as they launch and make the call on whether to test them.
Shopper Marketing Coordination. You are the bridge between digital retail media and in-store activation. When sales has an endcap display going live at 500 Target stores, you plan the Roundel campaign to amplify it. When a new SKU launches into Walmart, you coordinate the Walmart Connect strategy with the sell-in timeline. You work directly with the VP of Sales to align retail media spend with joint business plans, promotional calendars, and retailer-specific programs. You ensure that what’s happening on the screen and what’s happening in the store are part of the same plan.
Measurement & Reporting. You build the measurement framework connecting retail media performance to actual business outcomes across six-plus platforms. You think beyond last-touch ROAS—you measure incrementality, isolate the lift that media actually caused versus what would have happened organically, and connect advertising data to P&L metrics (contribution margin, inventory velocity, market share). You own budget forecasting, monthly reconciliation, and performance reporting to leadership.
Process & Playbooks. You establish campaign naming conventions, budget governance, and performance review cadences across all platforms. You create SOPs that document what works so the function can scale beyond you. You monitor platform roadmaps and rapidly test new capabilities.
AI & Automation. You use AI tools to multiply your output as a solo operator. Campaign structure generation, bulk keyword research, creative copy iteration, cross-platform reporting aggregation, competitive analysis—you have built workflows that let one person do the work that used to require a team. You are not waiting for someone to build you an AI toolkit; you are building it yourself.
