Senior Social Media Manager

Hoofddorp, NetherlandsFull-timeSeniorPosted Nov 6, 2026

Job description

Vertage is a new brand with a lot to say, and social is where much of it will be seen first. As Senior Social Media Manager, you own how Vertage and its leaders show up online. LinkedIn is the priority. Instagram and Tik. Tok extend our reach to new audiences and future talent.

Your role

Your first priority is to build the profile of our new brand and the online presence of our executive leaders. You run the social presence across our brand and leadership channels, from the content calendar to the posts themselves. You decide what we say, in which format and when, and you work closely with communications, brand, talent and regional teams to keep it consistent.

A large part of the role is working with senior leaders. You help them build a credible, recognisable presence on LinkedIn, and you turn their ideas into posts that sound like them. This is an individual role with a global remit. You work without a team, freelancers or agencies, so you are hands-on: you plan, write, design and edit.

There is a budget for paid social and tools.
