About Us

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.

What You’ll Own — And Deliver

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.

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.

What You’ll Accomplish in Year 1

• Within 60 days, deliver a full audit of existing retail media spend across all platforms with specific reallocation recommendations. Present a 12-month retail media plan to the CMO with projected outcomes by platform and brand.
• Deliver measurable performance improvement across Amazon Ads, Walmart Connect, Target Roundel, Instacart, DoorDash, and ibotta for eJam’s brand portfolio. You will set targets with the CMO, execute against them, and report on what you delivered—not what you launched.
• Deliver a unified measurement framework that connects retail media performance to P&L outcomes and is actively used for budget decisions—not a theoretical model, but a working system that leadership relies on to allocate spend.
• Deliver an integrated shopper marketing calendar, built with the sales team, that produces coordinated digital and in-store activations for every major promotional window, product launch, and joint business plan. The calendar drives execution, not just planning.
• Deliver documented SOPs, campaign playbooks, and naming conventions for every platform—complete enough that another operator could pick them up and execute without you in the room.
• Implement AI-powered workflows that allow you to manage six-plus platforms efficiently as a solo operator. Demonstrate measurable productivity gains from AI adoption in campaign management, reporting, and analysis.
• Deliver a data-backed recommendation on whether eJam should engage an agency partner, bring on a junior team member, or continue with the solo model—with projected ROI for each option and a clear path forward.

Requirements

YOU’LL THRIVE HERE IF YOU

• Have personally built and optimized campaigns in Amazon DSP, written AMC queries, and managed Sponsored Ads at the ASIN level. Not directed others—you’ve done the work yourself.
• Have hands-on experience across at least two additional retail media networks (Walmart Connect, Target Roundel, Instacart, Criteo, or similar), and understand how their measurement, bidding, and audience models differ.
• Come from CPG or consumer products, with a strong grasp of retail seasonality (Prime Day, Q4, back-to-school), product launches, and how media spend connects to sell-in windows and in-store velocity.
• Prefer being a hands-on operator. You’re not looking to manage a team—you want to be in-platform, building campaigns, analyzing performance, and solving problems directly.
• Think beyond ROAS. You can explain incrementality, identify when a high-ROAS campaign shouldn’t scale, and tie performance back to contribution margin and market share.
• View digital and in-store as a single system. You plan media to support in-store activations, collaborate with sales, and think across the full shopper journey.
• Use AI as a force multiplier in your day-to-day work—automating analysis, accelerating execution, and increasing your output without increasing headcount.
• Manage budgets with discipline. You forecast, reconcile, reallocate based on performance, and communicate clearly to leadership.
• Deliver measurable outcomes—not just activity. You can point to specific decisions and campaigns that drove revenue, margin, or market share—and back it up with data.
