Marketing Lead - Growth & Acquisition

The Context

Mill is at a pivotal point in our growth. We have found strong momentum in our Consumer business, and we are now focused on scaling household adoption of a new category that combines hardware, software, and service to change how people manage food waste.

At the same time, we are building toward a broader set of business lines. Alongside Consumer growth, we are developing commercial and institutional offerings that extend our impact through partners and enterprise environments. The two are complementary. Consumer establishes demand and habit, while Commercial expands reach and scale over time.

As we scale, we need to grow our acquisition engine with the same discipline we've brought to product. We are looking for a senior, hands-on growth marketer who can own paid and performance channels end to end — building an efficient, diversified, and continuously improving customer acquisition engine that serves both consumer and commercial buyers.

This role reports to the GM of Consumer and works closely with Growth, Analytics, Creative, Sales, and Business Operations.

The Mandate

This person owns Mill's customer acquisition engine — the paid channels, performance metrics, and testing infrastructure that turn marketing spend into efficient, scalable growth across our consumer and commercial business lines. The remit is both strategic and deeply operational:

• Own the paid acquisition engine. Own the paid acquisition engine. Manage strategy, budget, and day-to-day execution across paid social, paid search, programmatic/display, affiliate, and marketplace channels.
• Drive full-funnel growth. Drive full-funnel growth. Own the media mix and budget allocation across channels, set bidding and pacing strategy, and continuously reallocate spend toward the highest-efficiency opportunities.
• Build rigorous measurement and experimentation. Build rigorous measurement and experimentation. Own attribution, CAC/LTV modeling, and incrementality testing; run a disciplined test-and-learn program across audiences, offers, and channels.
• Partner on high-performing creative. Partner on high-performing creative. Brief Creative and agency partners on what's working in-market, and run a rapid creative-testing cadence to keep performance improving.
• Optimize the conversion funnel. Optimize the conversion funnel. Partner with Product and Growth on landing pages, checkout flow, and onboarding to lift conversion rate and improve payback period.
• Build the commercial acquisition motion. Build the commercial acquisition motion. Partner with Sales and Business Operations to build paid lead-generation and co-marketing programs that fill the pipeline for partner and enterprise buyers.

• Turn data into advantage. Turn data into advantage. Partner with Analytics and Data Science to understand what's driving (and limiting) efficient growth, and translate that insight into targeting, channel, and creative decisions.
• Apply learnings forward. Apply learnings forward. Build Mill's growth playbook so each channel, cohort, and campaign compounds on the last.
