Position Summary

We are looking for a Data Scientist to create cutting edge solutions for our Marketing Intelligence Engine (MIE), specializing in application of AI and ML to real-time bidding, investment decisions, and inflight campaign optimization.

The ideal candidate has hands-on experience implementing solutions in a modern architecture stack and enjoys working in a startup-like environment, both independently and with cross-functional teams.


Execute the Strategy:

  • Collaborate with a global team of data scientists, engineers, and product managers to deliver media measurement and optimization products to hundreds of users.
  • Apply AI, ML, and optimization algorithms to cross-campaign optimization, bidder algorithms, and data-driven investment decision making in a world of increasing media fragmentation and privacy-centric measurement.
  • Build data science with engineering toolkits for job orchestration, MLOps, CI/CD, RESTful APIs, and scalable infrastructure.
  • Scale data science across our agencies’ client portfolio. Data science should be simple, easy-to-explain, and anchored in business value.

Innovation and Development:

  • Push the boundaries of machine-assisted human decisioning, for example, automated optimization recommendations that supercharge the decision-making ability of campaign managers and media investment teams.
  • Foster a culture of innovation, encouraging the exploration of new techniques and technologies that enhance and scale our product capabilities.

Collaboration and Communication:

  • Move in lockstep with team members across Data Science, Product, and Engineering, ensuring clear and effective communication of product roadmaps, statuses, challenges, and successes.
  • Collaborate closely with product teams to understand their needs and integrate AI/ML technologies into our products that meet those needs, driving value and efficiency.

Desired Skills & Experience

Key technical skills:

  • Python: Advanced knowledge of Python is essential (Numpy, Pandas,…), with the ability to write efficient, clean, and commented code for model and package development, automation processes and application development. Experience writing RESTful APIs is a plus, e.g., FastAPI.
  • Machine Learning: Expertise in machine learning, including regression, classification, and ensemble methods like Random Forest and Gradient Boosting. Skilled in model development and feature engineering. Experience with Deep Learning is a plus.
  • Optimization: Proven familiarity and hands-on experience with optimization techniques and tools a big plus. Including but not limited to proficiency in software such as CPLEX, Gurobi, AMPL, GAMS or experience crafting custom optimization routines, employing methods such as genetic algorithms and stochastic gradient descent.
  • Statistical Analysis: Knowledge of Bayesian modelling is a preferred, while experience with Pyro is a plus. This may include hypothesis testing, time series forecasting and backtesting.
  • Data Management: Proficient in data manipulation and transformation techniques. Experience with SQL databases, ETL processes and frameworks (Dagster, Airflow, dbt,…), and data modeling as well as cloud-based data warehousing solutions like Snowflake or Google BigQuery. Understanding of data governance and quality control.
  • MLOps: Experience in overseeing the life cycle of machine learning models from development to production. This includes observability, reproducibility and evaluation of both data and models. Experience with MLflow a plus.
  • CI/CD: Experience with agile development methodologies, such as Scrum or Kanban. Proficiency in automation tools and frameworks for continuous integration and delivery (CI/CD), and monitoring model performance in production environments.
  • Cloud: Experience with cloud platforms (e.g. AWS, Azure, GCP) and containerization technologies like Docker and Kubernetes.


  • 3+ years of hands-on experience in designing and productionizing machine learning models and AI applications preferred.
  • Bachelor’s degree or higher in a CS or quantitative discipline: Computer Science/ Math/Statistics/Engineering preferred.
  • Excellent communication skills, with the ability to articulate complex technical concepts to non-technical stakeholders.
  • Experience with media optimization is a strong plus, especially in real-time bidding and non-linear optimization algorithms. Practical experience in other industries, for example, financial time series, is welcome too.
  • Demonstrated problem-solving and analytical thinking skills, with a focus on delivering practical and innovative solutions.
  • Adaptability and willingness to embrace new technologies and challenges in a fast-paced and evolving environment.
