About the Role

We’re looking for a proactive, self-sufficient Digital Marketing Manager who understands digital marketing and knows how to put a plan into action. This is a hands-on role focused primarily on digital marketing execution, with additional responsibility for improving the user experience across our website and e-commerce platform.

You’ll manage the day-to-day digital marketing calendar, coordinate campaigns, keep content moving, and ensure the right messages reach the right audiences at the right time. From email campaigns and LinkedIn posts to website updates, product content, and e-commerce initiatives, you’ll keep projects organized and deliverables on schedule.

We need someone who has done this work before, knows what needs to happen and when, and can move forward independently without extensive direction or step-by-step instructions. Priorities can shift quickly, and no two days will look exactly alike. You should be comfortable juggling multiple projects, anticipating what comes next, and adjusting quickly while maintaining a high level of accuracy.
