Marketing Analyst

Show
The Marketing Analyst is the measurement engine of the marketing team. You bring clarity to how Corston's marketing is performing across channels and audiences, build the reporting and dashboards the team relies on, and surface the insights that shape where we invest. Your primary focus will be digging into how our paid media campaigns perform as a primary focus, but also working across the web, CRM, and commercial data to connect activity to outcomes, making the case for what we should do next.
