About the Role

The Senior Data Science Engineer at Dentsu will lead the design and implementation of scalable, production-grade data science solutions that power our digital identity resolution and personalization capabilities across Dentsu platforms. You will collaborate with cross-functional teams—including product managers and data engineers—to architect machine learning pipelines, optimize model performance, and ensure seamless integration into cloud-native environments.

We seek an expert in deep learning techniques
applied to time series data.
The successful candidate will design, implement, and optimize time series models—within

  • Articulate trade-offs in model interpretability, generalization, and operational complexity, justifying the use of algorithmic models from both performance and deployment perspectives. Demonstrate where and why learned representations outperform the heuristic approach (e.g. in edge case detection, false-positive reduction, adaptive behavior over time).
  • Architect and implement end-to-end machine learning solutions for digital identity resolution.
  • Collaborate with engineering teams to ensure model scalability, reliability, and performance in production environments.
  • Partner with product and operations teams to define success metrics and monitor model impact.

Qualifications

  • 5+ years of experience in data science or machine learning roles.
  • Proven experience in coding and delivering deep learning solutions
    for time series data.
