The Ideal Candidate

You’re a hands-on media buyer who enjoys the challenge of growing sales profitably. You’ve managed e-commerce campaigns on Meta, know how to make decisions when performance changes, and are comfortable being accountable for a four-figure daily budget. You can explain what the numbers are telling you, what you’ll test next, and when it makes sense to scale or pull back.

You bring more than platform expertise. You’re curious about customers, offers, and the reasons people buy. You can spot promising angles, brief copywriters and designers clearly, and use campaign results to make creative feedback more specific. When an ad performs poorly, you look across the full customer journey before deciding what needs to change.

You take ownership of your projects, communicate your thinking concisely, and stay attentive to live campaign performance, including weekend checks when needed.
