The Role

Ready to build and scale? At A11, we believe that execution matters more than theory. We are looking for a (Senior) Growth Marketing Manager (m/f/d) who thrives in dynamic environments, enjoys moving between different industries and business models, and knows how to build marketing systems that deliver real results.

In this role, you will lead transformative marketing projects that challenge industry standards and deliver measurable impact for a wide range of established companies and young businesses.

Our marketing team is part of A11's Commercial division and consists of a diverse group of ambitious, curious and data-driven experts who support B2B and B2C companies in growing. We cover everything from Paid Media, CRM and MarTech through to Demand Generation, Lifecycle Marketing and Marketing Operations, and we work closely with our Data team whenever tracking and analytics topics overlap. We are also AI-native by design: we work with tools such as Claude, Gemini, Lovable, Pletor and Superscale, among others, and continuously test and refine new AI workflows to stay one step ahead. You will work across the entire marketing funnel, from strategy through execution to tracking and reporting, as a generalist with an individual focus, for example in one of the following areas:

• Performance Marketing (Paid Media: Search or Social)

Be responsible for:

• Leading growth projects with high C-level visibility, pragmatically and across different marketing stacks, industries and company stages

• Developing and implementing tailored strategies that match each client's growth stage, goals and internal structures
• Supporting our Associate Partners and Partners with project proposals and potential client acquisition
• Providing professional exchange and expertise: well-founded advice on channels, trends and best practices as a trusted point of contact
• Working with clients on site (remotely where needed) to ensure smooth implementation and build strong stakeholder relationships

Typical projects may include:

• Launching new channels, testing messaging or developing GTM strategies for new products or markets
• Developing and testing creatives and landing pages with GenAI tools and internal agents, as well as testing bidding tactics to optimise KPIs such as ROAS, CPA or retention
• Working closely with our Data team as well as Tech and Product to ensure clean tracking and relevant dashboards
• Driving app marketing initiatives, from ASO and app install campaigns through to in-app engagement and retention strategies
• Deriving insights and acting on them: monitoring key KPIs, identifying blockers and supporting quick, smart decisions

Your Profile:

• Senior-level experience in growth marketing, ideally in an agency or consultancy
• T-shaped marketing profile with a focus on Google Ads and Paid Social (Meta, TikTok, Snapchat, Reddit); LinkedIn is an advantage
• Data-minded: confident handling numbers, understanding tracking and attribution concepts, recognising patterns and turning them into concrete actions
• Confident using AI tools and marketing automation, with curiosity about what comes next
• Adaptable and eager to learn: you move confidently between companies of different sizes, industries and marketing maturity
• Strong communication and presentation skills
• You question existing rules of the game and continuously strive for improvement
• Willingness to travel within Europe and the UK for on-site client assignments
• Fluent in German and English; further languages (French, Spanish, Italian, Danish, Swedish) are an advantage

Please note that this position is based in Berlin, with frequent travel to our clients' offices.
