Growth Manager (Marketing focus)

About you

• Clear thinking. You use evidence to form a view on a commercial problem and identify the assumptions worth testing. You can make a practical decision even when the data is incomplete.
• Marketing instincts. You notice what earns people's attention and can explain why a campaign or proposition works. You bring original ideas and the judgement to connect 
• them to a customer need.
• Drive and ownership. You set yourself demanding goals, take initiative and follow through when the work becomes difficult. You take responsibility for the result and find ways to keep moving.
• Curiosity and learning. You pick up unfamiliar topics quickly, seek out feedback and experiment with AI and new tools.
• Teamwork and communication. You communicate fluently in English and turn ideas into clear briefs for colleagues and partners. You help others succeed, give candid feedback and welcome challenges to your thinking.
• Relevant experience. You bring around 1–2 years in strategy consulting, ideally at McKinsey, BCG or Bain, or in a startup or scale-up. Experience in both environments, including through internships, is a plus.
