Staff Data Scientist

About The Role
We are looking for a highly skilled Senior Data Scientist who can translate complex business problems into advanced analytical solutions. The ideal candidate combines deep expertise in statistical modeling, machine learning, and data engineering with a strong focus on Generative AI (GenAI), Large Language Models (LLMs), and Deep Learning. This role requires both technical leadership and strategic vision—from driving AI/ML innovation to mentoring junior team members, and collaborating across product, consulting, and engineering teams to bring AI-powered solutions to life. By applying your expertise in data science to the ad-server and retail media domains, you will contribute to delivering targeted and impactful advertising campaigns, optimizing ad inventory, and maximizing ROI for the organization.

○ Profi ciency in Python, PyTorch/TensorFlow, Hugging Face, and cloud-based ML platforms (AWS/GCP/Azure) with MLOps practices.

○ Skilled in building scalable data pipelines and ML systems for training, evaluation, and deployment at scale.

○ Solid grounding in Responsible AI principles including fairness, explainability, and bias mitigation.

• AI/ML & Generative AI Innovation

○ Lead the design, development, and deployment of scalable ML and DL solutions, with emphasis on LLMs and GenAI.

○ Build training, fine-tuning, evaluation, and serving pipelines for LLMs across use cases like content generation, summarization, semantic search, personalization, and multimodal AI.

○ Drive applied research, incorporating the latest in GenAI and foundation models into production-ready systems.

○ Ensure solutions are optimized for performance, security, reliability, and cost.

• Leadership & Collaboration

○ Provide technical and strategic leadership to cross-functional teams of Data Scientists and Analysts.

○ Collaborate with engineering and product teams to integrate AI solutions into customer-facing platforms.

○ Mentor junior data scientists; set and promote best practices in MLOps, Responsible AI, and ML system design.

○ Stay ahead of industry trends and incorporate them into roadmap planning.

• Project Management & Strategy

○ Drive the execution of business plans and projects

○ Manage the continuous improvement of data science initiatives

○ Direct the gathering and assessment of data for project goals

○ Develop contingency plans and adapt to changing business needs
