Marketing Strategy Consultant – MMM & Analytics (Mid-level) (m/w/d) (Hybrid/On-site)

Company Description Founded in 2014, we at Haensel AMS are an international, Berlin based, technology & data analytics solution provider. We specialized on everything around marketing measurement solutions, such as event tracking, 1st party customer data, attribution, media-mix modelling, CLTV, etc. We deploy and manage innovative machine learning and big data solutions tailored to the individual needs of our mainly international clients.

Role Description Join HAMS as a full-time Strategy Consultant in Berlin. In this role, you will bridge the gap between complex data science and executive decision-making. You will be the primary point of contact for our international clients, transforming Marketing Mix Modeling (MMM) outputs into high-impact growth strategies.

Your main responsibilities will include: Strategic Client Advisory:

Lead weekly consulting sessions with clients to review MMM performance, interpret model outputs, and provide clear, data-backed guidance on marketing spend. Insight Synthesis:

Dive deep into statistical model outputs (decay, saturation, and ROI curves) to distill actionable growth strategies for executive-level stakeholders. Budget Planning & Forecasting:

Develop data-driven investment roadmaps and predictive scenarios, helping clients understand the future impact of shifting spend across channels. Cross-Functional Feedback Loop:

Act as the "voice of the client" for our technical DS team, ensuring our models evolve to answer the most pressing business questions. Client Engagement:

What We’re Looking For: Educational Background:

An MSc or PhD degree in a quantitative field (e.g., Mathematics, Physics, Computer Science, Econometrics, or a related discipline). Alternatively, professional experience in Marketing Science, or Consulting where you have demonstrated the ability to bridge complex data with business strategy. Statistical & Analytical Expertise:

Extensive knowledge of statistics and data analytics. You must be comfortable "interrogating" the data to find the story behind the numbers. Communication Mastery:

Exceptional ability to explain technical concepts (like Bayesian priors or seasonality) to non-technical stakeholders without losing the "so what". Technical Proficiency : Strong command of Python, including libraries such as pandas and pymc. Industry Experience : Ideally, 2+ years of experience working with Marketing Mix Modeling (MMM), attribution, or large-scale marketing budget optimization . Nice-to-Haves:

Proficient in SQL across various dialects (e.g., Snowflake, BigQuery, Redshift), experience with data visualization tools (e.g., Tableau, Power BI, Looker).

What You Can Expect From Us: Exciting & Challenging Projects: Innovative projects for leading international clients that push the boundaries of what's possible. Culture of Continuous Growth: Thrive in an environment of learning, improvement, and that rewards your contributions.
