Job description

We offer

• No bullshit work environment
• Scale a venture that already has customers, revenue and real constraints
• Personal impact from day one
• Career option to move with the venture into its own company
• Awesome colleagues
• Onboarding phase mostly on site
• After that, a high share of home office and self-directed work

What you'll do

• Own the acquisition engine of a live commerce venture — traffic, feeds, conversion, margin
• Get products ranked and sold across marketplaces and comparison channels, not just in ad accounts
• Steer pricing and promotions against contribution margin, not against ROAS
• Kill the promotions that buy volume and lose money — and find the ones that don't
• Bring blended CAC down while volume goes up. That's the job.
• Run paid and organic social as part of the same engine — one funnel, not a channel silo
• Test and scale ads inside AI assistants — the channel that has no playbook yet

Your toolkit

• Feeds — Google Merchant Center down to attribute level: shipping, availability, GTIN, price history
• Feed layers — ChannelEngine or comparable, and the catalog behind them
• Marketplaces & comparison channels — Idealo, PriceRunner and their local equivalents
• Paid — Google, Meta, Shopping and social. Solid across the board, but the feed stays the core.
• Analytics — GA4, GTM, Looker or similar. You read attribution without fooling yourself.
• LLM ads — the emerging AI ad surfaces. Nobody is an expert yet; you're willing to be early.

Growth philosophy

• Contribution margin over ROAS
• Ranking is a product problem before it's a media problem
• Every promotion is a hypothesis with a price tag
• Fix the feed before you raise the budget
• Volume that only exists while you pay for it isn't growth
• New channels get tested small, scaled fast, and killed without drama

Requirements

• You've run acquisition for a real catalog, not for a landing page
• You can explain why a product dropped out of Shopping ranking — naming the attribute and the margin in the same sentence
• You're comfortable being accountable for gross profit, not for traffic
• You'd rather rebuild a feed than launch another campaign
• Fluent communication in English
