About the role

• Performance Marketing Manager driving e-commerce growth for a profitable watch startup. Overseeing budgets, channel strategies, and optimizing conversion rates across multiple platforms.

Responsibilities

• We are highly profitable, offer outstanding products and already sell worldwide through our existing shops — and this is just the beginning.
• We are currently rebuilding our infrastructure to be ready for the next stage of growth.
• For this we are looking for a performance marketing professional with real e‑commerce understanding: you don’t just manage budgets, you think about performance holistically, from the ad to the conversion in the shop.
• Channel ownership & expansion: You will take strategic and operational responsibility for existing channels.
• Agency management & search strategy: You will be the main point of contact for our Google & Bing Ads agency. You will steer the collaboration, challenge results, develop the strategic roadmap for Search + Shopping and unlock synergies across channels.
• Unlocking new potential: You will proactively build new social and native channels and elevate our remarketing to the next level.
• E‑commerce & conversion focus: For you, performance marketing doesn’t end at the ad. You analyze our shops’ performance, understand the user journey and provide data‑driven recommendations to improve shops and landing pages in order to maximize conversion rate and ROAS.
• International scaling: We operate worldwide. You will roll out successful campaign setups into new markets and support the launch of additional shops in the future.
• Collaboration & interfaces: You will work in a small, high‑performing team, coordinate closely with our newsletter specialist and collaborate intensively with our data team to make optimal use of tracking and analytics infrastructure.

Requirements

• Analytical marketer with shop knowledge: You have left the “wild years” of performance marketing behind, know the platforms inside out and are now eager to take true ownership in an extremely profitable environment.
• Experience: You bring 3–5 years of solid professional experience in performance marketing, ideally in a dynamic e‑commerce or scale‑up environment.
• Network expertise: You are confident working with Meta, Google Ads, Bing Ads, Outbrain/Taboola and RTB House.
• Pioneering mindset: You have first‑hand experience with or at least a strong strategic interest in channels such as TikTok and Pinterest.
• E‑commerce mindset: You are not just an “ads pusher.” You have a deep understanding of shop mechanics, conversion rate optimization (CRO) and the interaction between traffic quality and shop usability.
• Team player: You are a genuine team player who works collegially (e.g., in tandem with shop management) and enjoys sharing knowledge.

Benefits

• As a welcome gift you’ll receive a €300 watch budget — so you can experience our products from day one!
• Modern office with top equipment — you’ll get everything you need: laptop, monitor, headset.
• Flexible working hours, hybrid working model and a pleasant working atmosphere.
• Monthly additional benefits: €50 tax‑free allowance + job ticket + e‑bike card + fuel card.
• Personal development through a variety of training opportunities and career development prospects.
• Strong team spirit with regular events, attractive employee discounts and genuine camaraderie.
